File Issues and View Release Notes

DoltLab's source code is currently closed, but you can file DoltLab issues or view DoltLab's release notes in our issues repository.

Backup and Restore Volumes

DoltLab currently persists all data to local disk using Docker volumes. To backup or restore DoltLab's data, we recommend the following steps which follow Docker's official volume backup and restore documentation, with the exception of DoltLab's postgres server. To backup the postgres server we recommend dumping the database with pg_dump and restoring the database from the dump using psql.

Backing Up and Restoring Remote Data and User Uploaded Data

To backup DoltLab's remote data, the database data for all database on a given DoltLab instance, leave DoltLab's services up and run:
# backup remote data stored in DoltLab RemoteAPI's volume and save to a tar file
docker run --rm --volumes-from doltlab_doltlabremoteapi_1 -v $(pwd):/backup ubuntu tar cvf /backup/remote-data.tar /doltlab-remote-storage
This will create a tar file called remote-data.tar in your working directory.
To backup user uploaded files, run:
# backup remote data stored in DoltLab RemoteAPI's volume and save to a tar file
docker run --rm --volumes-from doltlab_doltlabfileserviceapi_1 -v $(pwd):/backup ubuntu tar cvf /backup/user-uploaded-data.tar /doltlab-user-uploads
This will create a tar file called user-uploaded-data.tar in your working directory.
Before restoring DoltLab's volumes from a backup, first, stop the running DoltLab services, prune the Docker containers, and remove the old volume(s):
cd doltlab
​
# stop the DoltLab services
docker-compose stop
​
# prune containers
docker container prune
​
# remove the remote data volume
docker volume rm doltlab_doltlab-remote-storage
​
# remove the user uploaded data
docker volume rm doltlab_doltlab-user-uploads
Next, start DoltLab's services using the start-doltlab.sh script. After the script completes, cd into the directory containing the remote-data.tar backup file and run:
# restore remote data from tar
docker run --rm --volumes-from doltlab_doltlabremoteapi_1 -v $(pwd):/backup ubuntu bash -c "cd /doltlab-remote-storage && tar xvf /backup/remote-data.tar --strip 1"
To restore user uploaded data, cd into the directory containing user-uploaded-data.tar and run:
# restore remote data from tar
docker run --rm --volumes-from doltlab_doltlabfileserviceapi_1 -v $(pwd):/backup ubuntu bash -c "cd /doltlab-user-uploads && tar xvf /backup/user-uploaded-data.tar --strip 1"

Backing Up and Restoring PostgreSQL Data

For backing up data from DoltLab's postgres server, we recommend executing a data dump with pg_dump. To do so, keep DoltLab's services up and run:
For DoltLab v0.7.0 and later, use --network doltlab below.
# dump postgres to postgres-dump.sql
docker run --rm --network doltlab_doltlab -e PGPASSWORD=<POSTGRES_PASSWORD> -v $(pwd):/doltlab-db-dumps postgres:13-bullseye bash -c "pg_dump --host=doltlab_doltlabdb_1 --port=5432 --username=dolthubadmin dolthubapi > /doltlab-db-dumps/postgres-dump.sql"
The value of PGPASSWORD should be the POSTGRES_PASSWORD set when DoltLab was first deployed.
To restore a postgres server from postgres-dump.sql, first stop the running DoltLab services, remove the stopped containers, and remove the old postgres server volume:
cd doltlab
​
# stop DoltLab
docker-compose stop
​
# remove containers
docker container prune
​
# remove old postgres data volume
docker volume rm doltlab_doltlabdb-data
Next, edit the postgres-dump.sql file by adding the line SET session_replication_role = replica; near the top of the file:
SET statement_timeout = 0;
SET lock_timeout = 0;
SET idle_in_transaction_session_timeout = 0;
SET client_encoding = 'UTF8';
SET standard_conforming_strings = on;
SELECT pg_catalog.set_config('search_path', '', false);
SET check_function_bodies = false;
SET xmloption = content;
SET client_min_messages = warning;
SET row_security = off;
​
/* We add this to disable triggers and rules during import */
SET session_replication_role = replica;
...
​Start DoltLab's services again using the start-doltlab.sh script. After the script completes, cd into the directory containing the postgres-dump.sql file and run:
For DoltLab v0.7.0 and later, use --network doltlab below.
# import the postgres dump into the running server
docker run --rm --network doltlab_doltlab -e PGPASSWORD=<POSTGRES_PASSWORD> -v $(pwd):/doltlab-db-dumps postgres:13-bullseye bash -c "psql --host=doltlab_doltlabdb_1 --port=5432 --username=dolthubadmin dolthubapi < /doltlab-db-dumps/postgres-dump.sql"

Send Service Logs to DoltLab Team

DoltLab is comprised of multiple services running in a single Docker network via Docker compose. Logs for a particular service can be viewed using the docker logs <container name> command. For example, to view to logs of doltlabapi service, run:
docker logs doltlab_doltlabapi_1
If you need to send service logs to the DoltLab team, first locate the logs on the host using the docker inspect command, then cp the logs to your working directory:
DOLTLABAPI_LOGS=$(docker inspect --format='{{.LogPath}}' doltlab_doltlabapi_1)
cp "$DOLTLABAPI_LOGS" ./doltlab-api-logs.json
Next change permissions on the copied file to enable reads by running:
chmod 0644 ./doltlab-api-logs.json
Finally, download the copied log file from your DoltLab host using scp. You can then send this and any other log files to the DoltLab team member you're working with via email.

Upgrading DoltLab

Upgrading to newer versions of DoltLab requires downtime. This means that DoltLab Admins will need to kill the old version of DoltLab, and install the newer one.
In addition, some early versions have different database schemas than newer ones. If the docker volumes of an old version of DoltLab contain non-precious or test-only data, then DoltLab Admins can simply remove these Docker volumes and run the start-doltlab.sh script from the newer DoltLab version. This script will simply create new Docker volumes with the appropriate schema for that DoltLab version.
If you want to upgrade your DoltLab version without losing any data, please follow the upgrade guidelines below.

Upgrade from DoltLab v0.6.0 to v0.7.0+

Starting with DoltLab v0.7.0, the ./start-doltlab.sh script will create a doltlab docker network externally, instead of allowing Docker Compose to create the network automatically. If you're upgrading to v0.7.0 or higher from an earlier DoltLab version, remove any doltlab or *_doltlab networks on the host before installing v0.7.0.

Upgrade from DoltLab v0.3.0+

DoltLab versions >= v0.3.0 support schema migrations without data loss. To upgrade to a DoltLab version after v0.3.0, simply stop your old version of DoltLab, then download and unzip the newer DoltLab version to the same location as your previous version. This will ensure that when you start the new version of DoltLab using the start-doltlab.sh script, the old DoltLab version's Docker volumes get attached to the new version's containers.
# stop old DoltLab
cd doltlab
docker-compose stop
cd ../
rm -rf doltlab
​
# download and unzip newer DoltLab
curl -OL https://doltlab-releases.s3.amazonaws.com/linux/amd64/doltlab-latest.zip
unzip doltlab-latest.zip -d doltlab
​
# start DoltLab
cd doltlab
./start-doltlab.sh

Upgrade from DoltLab v0.2.0 to v0.3.0

To upgrade without data loss, follow the same instructions for upgrading found in the Upgrade from DoltLab v0.1.0 v0.2.0 section.

Upgrade from DoltLab v0.1.0 to v0.2.0 Without Data Loss

To upgrade DoltLab v0.1.0 to v0.2.0, leave DoltLab v0.1.0's services running and connect a PostgreSQL client from inside the doltlab_doltlab Docker network to the running doltlab_doltlabdb_1 server. On the DoltLab host machine, run:
# dump data from DoltLab v0.1.0's postgres server to doltlab-db-dumps
docker run --rm --network doltlab_doltlab -e PGPASSWORD=<POSTGRES_PASSWORD> -v $(pwd):/doltlab-db-dumps postgres:13-bullseye bash -c "pg_dump --data-only --host=doltlab_doltlabdb_1 --port=5432 --username=dolthubadmin dolthubapi > /doltlab-db-dumps/doltlab-v0.1.0-dump-data-only.sql"
The value of PGPASSWORD should be the POSTGRES_PASSWORD set when DoltLab v0.1.0 was first deployed. You should now see the SQL dump file called doltlab-v0.1.0-dump-data-only.sql.
Next, edit the doltlab-v0.1.0-dump-data-only.sql file by adding the line SET session_replication_role = replica; near the top of the file:
SET statement_timeout = 0;
SET lock_timeout = 0;
SET idle_in_transaction_session_timeout = 0;
SET client_encoding = 'UTF8';
SET standard_conforming_strings = on;
SELECT pg_catalog.set_config('search_path', '', false);
SET check_function_bodies = false;
SET xmloption = content;
SET client_min_messages = warning;
SET row_security = off;
​
/* We add this to disable triggers and rules during import */
SET session_replication_role = replica;
...
You can now stop the DoltLab v0.1.0 services and delete the Docker caches and stopped containers on the host by running:
cd doltlab
​
# stop DoltLab
docker-compose stop
​
# remove containers
docker container prune
Next, remove the Docker volume used with DoltLab v0.1.0's doltlab_doltlabdb_1 postgres server by running:
docker volume rm doltlab_doltlabdb-data
​Download DoltLab v0.2.0, unzip it's contents, and start DoltLab v0.2.0's services by running the start-doltlab.sh script.
After the script completes, confirm DoltLab v0.2.0's services are running with docker ps:
docker ps

Now, connect a PostgreSQL client from inside the doltlab_doltlab Docker network to the running doltlab_doltlabdb_1 server to perform the data dump import. Then, update the has_dolt column in the users table.
# import the data dump into the running DoltLab v0.2.0 postgres server
docker run --rm --network doltlab_doltlab -e PGPASSWORD=<POSTGRES_PASSWORD> -v $(pwd)/doltlab-db-dumps:/doltlab-db-dumps postgres:13-bullseye bash -c "psql --host=doltlab_doltlabdb_1 --port=5432 --username=dolthubadmin dolthubapi < /doltlab-db-dumps/doltlab-v0.1.0-dump-data-only.sql"
​
# update the users table to prevent DoltLab v0.2.0 error
docker run --rm --network doltlab_doltlab -e PGPASSWORD=<POSTGRES_PASSWORD> -v $(pwd)/doltlab-db-dumps:/doltlab-db-dumps postgres:13-bullseye bash -c "psql --host=doltlab_doltlabdb_1 --port=5432 --username=dolthubadmin dolthubapi -c 'update users set has_dolt = 'false';'"
You have now completed the upgrade, and should no be running DoltLab v0.2.0 with your postgres data from DoltLab v0.1.0.

Connect with the DoltLab Team

If you need to connect to a DoltLab team member, the best way to do so is on Discord, in the #doltlab server.

Authenticate a Dolt Client to use a DoltLab Account

As of Dolt v0.39.0, the dolt login command can be used to authenticate against DoltLab instances.
To authenticate a client against DoltLab with this command, use the --auth-endpoint, --login-url, and --insecure arguments to point your Dolt client at the DoltLab instance you want to authenticate against.
--auth-endpoint should point at the DoltLab RemoteAPI Server running on port 50051. --login-url should point at the DoltLab instance's credentials page. --insecure a boolean flag, should be used since DoltLab does not currently support TLS gRPC connections.
dolt login --insecure --auth-endpoint doltlab.dolthub.com:50051 --login-url http://doltlab.dolthub.com/settings/credentials
Running the command will open your browser window to the --login-url with credentials populated in the "Public Key" field. Simply add a "Description" and click "Create", then return to your terminal to see your Dolt client successfully authenticated.
Credentials created successfully.

Next, login to your DoltLab account, click your profile image, then click "Settings" and then "Credentials".
Paste the public key into the "Public Key" field, write a description in the "Description" field, then click "Create".
Your Dolt client is now authenticated for this DoltLab account.

Monitor DoltLab with cAdvisor and Prometheus

As of DoltLab v0.3.0, Prometheus gRPC service metrics for DoltLab's Remote API Server, doltlabremoteapi, and DoltLab's Main API server, doltlabapi, are published on port 7770.
The metrics endpoints for these services are available at endpoints corresponding to their container name. For DoltLab's Remote API, thats :7770/doltlabremoteapi, and for DoltLab's Main API that's :7770/doltlabapi.
You can view the doltlabremoteapi service metrics for our DoltLab demo instance here, http://doltlab.dolthub.com:7770/doltlabremoteapi and you can view the doltlabapi service metrics here http://doltlab.dolthub.com:7770/doltlabapi.
To make these endpoints available to Prometheus, open port 7770 on your DoltLab host.
We recommend monitoring DoltLab with cAdvisor, which will expose container resource and performance metrics to Prometheus. Before running cAdvisor, open port 8080 on your DoltLab host as well. cAdvisor will display DoltLab's running containers via a web UI on :8080/docker and will publish Prometheus metrics for DoltLab's container at :8080/metrics by default.
Run cAdvisor as a Docker container in daemon mode with:
docker run -d -v /:/rootfs:ro -v /var/run:/var/run:rw -v /sys:/sys:ro -v /var/lib/docker/:/var/lib/docker:ro -v /dev/disk/:/dev/disk:ro -p 8080:8080 --name=cadvisor --privileged gcr.io/cadvisor/cadvisor:v0.39.3
To run a Prometheus server on your DoltLab host machine, first open port 9090 on the DoltLab host. Then, write the following prometheus.yml file on the host:
global:
scrape_interval: 5s
evaluation_interval: 10s
scrape_configs:
- job_name: cadivsor
static_configs:
- targets: ["host.docker.internal:8080"]
- job_name: prometheus
static_configs:
- targets: ["localhost:9090"]
- job_name: doltlabremoteapi
metrics_path: "/doltlabremoteapi"
static_configs:
- targets: ["host.docker.internal:7770"]
- job_name: doltlabapi
metrics_path: "/doltlabapi"
static_configs:
- targets: ["host.docker.internal:7770"]
Then, start the Prometheus server as a Docker container running in daemon mode:
docker run -d --add-host host.docker.internal:host-gateway --name=prometheus -p 9090:9090 -v "$(pwd)"/prometheus.yml:/etc/prometheus/prometheus.yml:ro prom/prometheus:latest --config.file=/etc/prometheus/prometheus.yml
--add-host host.docker.internal:host-gateway is only required if running the Prometheus server on the DoltLab host. If running it elsewhere, this argument may be omitted, and the host.docker.internal hostname in prometheus.yml can be changed to the hostname of your DoltLab host.

Connect to an SMTP Server with Implicit TLS

Starting with DoltLab v0.4.2, connections to existing SMTP servers using implicit TLS (on port 465, for example) are supported. To connect using implicit TLS, edit the docker-compose.yaml included in the DoltLab zip. Under the doltlabapi section, in the command block, add the following argument:
...
doltlabapi:
...
command:
...
-emailImplicitTLS
...
After adding the argument, restart DoltLab for it to take effect. Additionally, TLS verification can be skipped by adding the additional argument -emailInsecureTLS.

Troubleshoot SMTP Server Connection Problems

DoltLab requires a connection to an existing SMTP server in order for users to create accounts, verify email addresses, reset forgotten passwords, and collaborate on databases.
Starting with DoltLab v0.4.1, the default user admin is created when DoltLab starts up, which allows admins to sign in to their DoltLab instance even if they are experiencing SMTP server connection issues.
To help troubleshoot and resolve SMTP server connection issues, we've published the following go tool to help diagnose the SMTP connection issues on the host running DoltLab.
Starting with DoltLab v0.4.2, this tool is now included as an executable binary in DoltLab's zip, called smtp_connection_helper.
For usage run ./smtp_connection_helper --help which will output:
​
'smtp_connection_helper' is a simple tool used to ensure you can successfully connect to an smtp server.
If the connection is successful, this tool will send a test email to a single recipient from a single sender.
By default 'smtp_connection_helper' will attempt to connect to the SMTP server with STARTTLS. To use implicit TLS, use --implicit-tls
​
Usage:
​
./smtp_connection_helper \
--host <smtp hostname> \
--port <smtp port> \
--from <email address> \
--to <email address> \
--message {This is a test email message sent with smtp_connection_helper!} \
--subject {Testing SMTP Server Connection} \
--client-hostname {localhost} \
--auth <plain|login|external|anonymous|oauthbearer|disable> \
[--username smtp username] \
[--password smtp password] \
[--token smtp oauth token] \
[--identity smtp identity] \
[--trace anonymous trace] \
[--implicit-tls] \
[--insecure]
​
​
To send a test email using plain authentication, run:
./smtp_connection_helper \
--host existing.smtp.server.hostname \
--port 587 \ #STARTTLS port
--auth plain \
--username XXXXXXXX \
--password YYYYYYY \
--from [email protected] \
--to [email protected]
Sending email with auth method: plain
Successfully sent email!
To send a test email using plain authentication with implicit TLS, run:
./smtp_connection_helper \
--host existing.smtp.server.hostname \
--port 465 \ #TLS Wrapper Port
--implicit-tls \
--auth plain \
--username XXXXXXXX \
--password YYYYYYY \
--from [email protected] \
--to [email protected]
Sending email with auth method: plain
Successfully sent email!
To quickly get up and running with an existing SMTP server, we recommend using Gmail's. Once you've created a Gmail account, navigate to your account page and click the Security tab. Under the section "How you sign in to Google", click 2-Step Verification. If you have not yet setup 2-Step Verification, follow the prompts on this page to enable it.
After 2-Step Verification is set up, at the bottom of the page click "App passwords". Select app Mail and select a device, then click "Generate" to generate a password. This generated password can be supplied along with your Gmail email address to send emails with smtp_connection_helper and DoltLab.
./smtp_connection_helper \
--host smtp.gmail.com \
--port 587 \
--auth plain \
--username [email protected] \
--password <generated App password> \
--from [email protected] \
--to [email protected]
Sending email with auth method: plain
Successfully sent email!

Prevent Unauthorized User Account Creation

DoltLab for non-enterprise use currently supports explicit email whitelisting to prevent account creation by unauthorized users.
To enable DoltLab's email whitelisting feature, edit the docker-compose.yaml file included in DoltLab's zip.
Under the doltlabapi section, in the command block, remove the argument -dolthubWhitelistAllowAll. Restart your DoltLab instance for this to take effect.
Once DoltLab is restarted, your DoltLab instance will now check a PostgreSQL table called email_whitelist_elements before permitting account creation. Only user's with email addresses present in this table will be able to create accounts on your DoltLab instance.
To whitelist an email for account creation in your instance, you will need to insert their email address into the email_whitelist_elements table.
As of DoltLab v0.4.2, a script to easily connect to your DoltLab instance's running PostgreSQL server is included in the zip, called shell-db.sh.
Use this script by supplying the POSTGRES_PASSWORD you used to start your DoltLab instance, as PGPASSWORD here. Run:
PGPASSWORD=<your postgres password> ./shell-db.sh
You will see a dolthubapi=# PostgresSQL prompt connected to your DoltLab instance.
You can now execute the following INSERT to allow a specific user with [email protected] to create an account on your DolLab instance:
INSERT INTO email_whitelist_elements (email_address, updated_at, created_at) VALUES ('[email protected]', CURRENT_TIMESTAMP, CURRENT_TIMESTAMP);

Use an external PostgreSQL server with DoltLab

You can connect a DoltLab instance to an external PostgreSQL server version 13 or later. To connect, in DoltLab's docker-compose.yaml, supply the host and port for the external server to doltlabapi's -pghost and -pgport arguments.
doltlabapi:
...
command:
...
-pghost <host>
-pgport <port>
...
You can also remove the doltlabdb section and all references to it and doltlabdb-data in the docker-compose.yaml file.
Before (re)starting DoltLab with this change, you will also need to execute the following statements in your external PostgreSQL server:
CREATE ROLE dolthubapi WITH LOGIN PASSWORD '$DOLTHUBAPI_PASSWORD';
CREATE DATABASE dolthubapi;
GRANT ALL PRIVILEGES ON DATABASE dolthubapi TO dolthubapi;
CREATE EXTENSION citext SCHEMA public;
GRANT ALL PRIVILEGES ON ALL TABLES IN SCHEMA public TO dolthubapi;

Expose a DoltLab instance with ngrok

As of DoltLab v0.5.5, DoltLab instances can be exposed with ngrok. "How to expose DoltLab with ngrok" contains the instructions for this process, however, we do not recommend doing this for production DoltLab instances. This process requires one of DoltLab's services to be run without authentication, which may expose sensitive data. Do this at your own risk.

DoltLab Jobs

Jobs were recently introduced on DoltHub and are available now on DoltLab ^v0.7.0. DoltLab Jobs are stand-alone, long-running Docker containers that perform specific tasks for DoltLab users behind the scenes. DoltLab v0.7.0 includes a single Job type, the Import Job, for large file imports. But, additional Jobs will be added in subsequent versions of DoltLab.
As a result of the new Jobs infrastructure, DoltLab now requires more memory and disk. The amount of each of these depends on how users will use your instance. Here are the current end user limits of DoltLab Jobs as of v0.7.0:
Job Type
Database Size Limit
File Size Limit
File Import
150 GB
1 GB for .csv, 200 MB for .sql
If you want to run a DoltLab instance that can support these end user limits, we recommend running DoltLab on a host with at least 64 GB of memory, and 20 TBs of disk. These recommended amounts will decrease as we continue to improve Dolt's resource efficiency and utilization.

Import Jobs

Under the hood, when a user uploads a file to DoltLab, a new Job is kicked off that copies that file into a new Docker container running a dolt binary. This Job container executes dolt table import <file> or dolt sql < <file>, depending on the file type of the uploaded file, which imports the data into a clone of the target database. The container finishes by opening a pull request containing the imported data.
What's import to note about the Import Job process is how it can impact disk and memory utilization on a DoltLab host.
For example, let's say a user uploads a 100 MB .csv on a 10 GB DoltLab database. First, the uploaded file is downloaded into the Job container, writing, temporarily, the 100 MB file to disk. Second, the target database is cloned into the container, using an additional 10 GB's of disk. Finally, the import process begins with dolt table import <file>, which uses additional disk (a variable amount), in the form of temporary files that Dolt writes to disk in order to perform the import.
Importing also uses a variable amount of memory depending on the size of the cloned database and the size of the file being imported. In our example, the import completes in about 30 seconds, but uses about 5 GB of memory at its peak.
For this reason, we recommend running DoltLab on a host with as much disk and memory as you can, especially if your users plan on doing large file imports, or a large number of imports in parallel.
Import performance, memory and disk utilization are all areas of concentration for our team in the coming months. We are committed to bringing all of these down for Dolt, DoltHub, and DoltLab, so stay tuned for updates.

Disable Usage Metrics

By default, DoltLab collects first-party metrics for deployed instances. We use DoltLab's metrics to determine how many resources to allocate toward its development and improvement.
As of v0.7.0, DoltLab does not collect third-party metrics, and additionally, DoltLab's first-party metrics can be disabled. To disable metrics, edit the start-doltlab.sh script and remove run_with_metrics from the _main function.

Migrate Old Format DoltLab Databases

Unlike DoltHub, DoltLab does not support automatic database migration for old format Dolt databases. Instead, old format database hosted on DoltLab need to be migrated manually. To migrate a DoltLab database:
  1. 1.
    Create a new database on DoltLab.
  2. 2.
    Clone the database you want to migrate.
  3. 3.
    Run dolt migrate in the cloned database.
  4. 4.
    Add the remote of the new DoltLab database to the cloned database with dolt remote add <remote name> http://<host ip>:50051/<owner>/<new db name>.
  5. 5.
    Push the migrated clone to the new database with dolt push <remote name> <branch name>.
Starting with DoltLab v0.7.6, DoltLab allows administrators to customize the logo used across their DoltLab instance. At the time of this writing, custom logos used on DoltLab can have a maximum height of 24px and a maximum width of 112px. If a custom logo is used on DoltLab, the footer of the DoltLab instance will display the text "Powered by DoltLab" below the custom logo.
You can use a custom logo on DoltLab by creating an admin-config.yaml file. By default, DoltLab will look for this file in the unzipped doltlab directory that contains DoltLab's other assets. However, this path can be overridden by setting the environment variable ADMIN_CONFIG.
# admin-config.yaml
logo: /path/to/custom/logo.png
Add the field logo to the admin-config.yaml file with the absolute path of custom logo. png, svg, and jpeg are the supported image file types for the custom logo.
Save the file, and restart your DoltLab instance using the start-doltlab.sh script. When DoltLab restarts, you will see the custom logo in place of the DoltLab logo.

Customize automated emails

Starting with DoltLab v0.7.6, DoltLab allows administrators to customize the automated emails their DoltLab instance sends to its users. Included in the DoltLab zip is a directory called templates that stores the golang text template files your DoltLab instance will use to generate emails. Each file is named according to use case and the names of the files should NOT be changed.
  • email/collabInvite.txt sent to invite user to be a database collaborator.
  • email/invite.txt sent to invite a user to join an organization.
  • email/issueComment.txt sent to notify user that an issue received a comment.
  • email/issueState.txt sent to notify user that an issue's state has changed.
  • email/pullComment.txt sent to notify user that a pull request received a comment.
  • email/pullCommits.txt sent to notify user that a pull request received a commit.
  • email/pullReview.txt sent to notify user that a pull request review's state has changed.
  • email/pullState.txt sent to notify user that a pull request's state has changed.
  • email/recoverPassword.txt sent to provide user with a link to reset their password.
  • email/resetPassword.txt sent to notify a user that their password has been reset.
  • email/verify.txt sent to a user to verify their email account.
To alter the text within one of the above files, we recommend only changing the hardcoded text between the Actions and replacing the use of {{.App}}, which normally evaluates to "DoltLab", with the name of your company or team.
You should not change any template definitions, indicated with {{define "some-template-name"}} syntax, within these files as doltlabapi specifically uses these definitions.
To better illustrate how to modify these files, let's look at an example. Here is the default email/verify.txt template:
{{define "verifySubject" -}}
[{{.App}}] Please verify your email address.
{{- end}}
​
{{define "verifyHTML" -}}
<html>
<body>
<p>To secure access to your {{.App}} account, we need you to verify your email address: {{.Address}}.
<p><a href="{{.BaseURL}}/users/{{.Username}}/emailAddresses/{{.Address}}/verify?token={{.Token}}">Click here to verify your email address.</a>
<p>You’re receiving this email because you created a new {{.App}} account or added a new email address. If this wasn’t you, please ignore this email.
</body>
</html>
{{- end}}
​
{{define "verifyText" -}}
Hi,
​
To secure access to your {{.App}} account, we need you to verify your email address: {{.Address}}.
​
Click the link below to verify your email address:
​
{{.BaseURL}}/users/{{.Username}}/emailAddresses/{{.Address}}/verify?token={{.Token}}
​
You're receiving the email because you created a new {{.App}} account or added a new email address. If this wasn't you, please ignore this email.
{{- end}}
Above, three templates are defined verifySubject, verifyHTML, and verifyText. We will not add or remove any of these templates and we won't change their names, but we will replace the {{.App}} field with the name of our company, Acme, Inc.'s DoltLab instance, "AcmeLab". We'll also modify the hardcoded text to be specific to our DoltLab instance's users.
After replacing {{.App}} with "AcmeLab", our file looks like:
{{define "verifySubject" -}}
[AcmeLab] Please verify your email address.
{{- end}}
​
{{define "verifyHTML" -}}
<html>
<body>
<p>To secure access to your AcmeLab account, we need you to verify your email address: {{.Address}}.
<p><a href="{{.BaseURL}}/users/{{.Username}}/emailAddresses/{{.Address}}/verify?token={{.Token}}">Click here to verify your email address.</a>
<p>You’re receiving this email because you created a new AcmeLab account or added a new email address. If this wasn’t you, please ignore this email.
</body>
</html>
{{- end}}
​
{{define "verifyText" -}}
Hi,
​

​
Click the link below to verify your email address:

​
You're receiving the email because you created a new AcmeLab account or added a new email address. If this wasn't you, please ignore this email.
{{- end}}
Lastly, let's customize this email with the contact information of our AcmeLab admin, in case users have any questions. We want to add the same information to the verifyHTML template and the verifyText template so that it appears for either supported email format:
{{define "verifySubject" -}}
[AcmeLab] Please verify your email address.
{{- end}}
​
{{define "verifyHTML" -}}
<html>
<body>
<p>Thank you for signing up for AcmeLab!
<p>To secure access to your AcmeLab account, we need you to verify your email address: {{.Address}}.
<p><a href="{{.BaseURL}}/users/{{.Username}}/emailAddresses/{{.Address}}/verify?token={{.Token}}">Click here to verify your email address.</a>
<p>You’re receiving this email because you created a new AcmeLab account or added a new email address. If this wasn’t you, please ignore this email.
<p> If you need further assistance, please reach out to Kevin at [email protected]
</body>
</html>
{{- end}}
​
{{define "verifyText" -}}

Once we save our edits, we can restart our DoltLab instance for the changes to take affect.

Customize DoltLab colors

Starting with DoltLab v0.8.1, DoltLab allows administrators to customize the color of certain assets across their DoltLab instance.
You can specify custom RGB values for DoltLab's assets by defining them in an admin-config.yaml file. By default, DoltLab will look for this file in the unzipped doltlab directory that contains DoltLab's other assets. However, this path can be overridden by setting the environment variable ADMIN_CONFIG.
# admin-config.yaml
theme:
custom:
rgb_accent_1: "252, 66, 201"
rgb_background_accent_1: "24, 33, 52"
rgb_background_gradient_start: "31, 41, 66"
rgb_button_1: "61, 145, 240"
rgb_button_2: "31, 109, 198"
rgb_link_1: "31, 109, 198"
rgb_link_2: "61, 145, 240"
rgb_link_light: "109, 176, 252"
Add the field theme, then custom to the admin-config.yaml file. In the custom block, specify the RGB values you'd like for each of the possible fields. The values above are the default RGB values used in DoltLab.
After adding your custom values, save the file, and restart your DoltLab instance using the start-doltlab.sh script. When DoltLab restarts, you will see the custom colors across the site.

Use a domain name with DoltLab

It's common practice to provision a domain name to use for a DoltLab instance. To do so, secure a domain name and map it to the stable, public IP address of the DoltLab host. Then, supply the domain name as the value to the HOST_IP environment variable when starting DoltLab. Let's look at an example using services offered by AWS.
Let's say we've have set up and run an EC2 instance with the latest version of DoltLab and have successfully configured its Security Group to allow ingress traffic on 80, 100, 4321, and 50051. By default, this host will have a public IP address assigned to it, but this IP is unstable and will change whenever the host is restarted.
First, we should attach a stable IP to this host. To do this in AWS, we can provision an Elastic IP Address (EIP).
Next, we should associate the EIP with our DoltLab host by following these steps. Once this is done, the DoltLab host should be reachable by the EIP.
Finally, we can provision a domain name for the DoltLab host through AWS Route 53. After registering the new domain name, we need to create an A record that's attached to the EIP of the DoltLab host. To do so, follow the steps for creating records outlined here.
Your DoltLab host should now be accessible via your new domain name. You can now stop your DoltLab server and replace the value of the environment variable HOST_IP with the domain name, then restart DoltLab.
In the event you are configuring your domain name with an Elastic Load Balancer, ensure that it specifies Target Groups for each of the ports required to operate DoltLab, 80, 100, 4321, and 50051.
