Operations guides for Sourcegraph with Docker Compose

Operations guides specific to managing Sourcegraph with Docker Compose installations.

Trying to deploy Sourcegraph? Refer to our installation guide.

Featured guides

Deploy

Refer to our installation guide for more details on how to deploy Sourcegraph.

Migrating from another deployment type? Refer to our migrating to Docker Compose guides.

Configure

We strongly recommend that you create and run Sourcegraph from your own fork of the reference repository to track customizations to the Sourcegraph Docker Compose YAML. This will make upgrades far easier.

  • Create a fork of the sourcegraph/deploy-sourcegraph-docker repository.

    WARNING: Set your fork to private if you plan to store secrets (SSL certificates, external Postgres credentials, etc.) within the repository.

  • Clone your fork using the repository's URL.

    git clone $FORK_URL
  • Add the reference repository as an upstream remote so that you can get updates.

    git remote add upstream https://github.com/sourcegraph/deploy-sourcegraph-docker
  • Create a release branch to track all of your customizations to Sourcegraph. This branch will be used to upgrade Sourcegraph and install your Sourcegraph instance.

    # Specify the version you want to install
    export SOURCEGRAPH_VERSION="v3.29.1"
    # Check out the selected version for use, in a new branch called "release"
    git checkout $SOURCEGRAPH_VERSION -b release
  • Make and commit customizations to the Sourcegraph Docker Compose YAML to your release branch.

Configuration best practices

  • The version argument in the YAML file must be the same as in the standard deployment
  • Users should only alter the YAML file to adjust resource limits, or duplicate container entries to add more container replicas

Upgrade

This requires you to have set up configuration for Docker Compose.

When you upgrade, merge the corresponding upstream release tag into your release branch.

# fetch updates
git fetch upstream
# merge the upstream release tag into your release branch
git checkout release
git merge upstream v$SOURCEGRAPH_VERSION

Address any merge conflicts you might have.

If you are upgrading a live deployment, make sure to check the release upgrade notes for any additional actions you need to take before proceeding. Then run:

# Fully stop the Docker Compose instance of Sourcegraph currently running
docker-compose down --remove-orphans
# Start Docker Compose again, now using the latest contents of the Sourcegraph configuration
docker-compose up -d

You can see what's changed in the Sourcegraph changelog.

Use an external database

The Docker Compose configuration has its own internal PostgreSQL and Redis databases. To preserve this data when you kill and recreate the containers, you can use external services for persistence.

Manage storage

The Sourcegraph Docker Compose definition uses Docker volumes to store its data. These volumes are stored at /var/lib/docker/volumes by default on Linux.

Guides for managing cloud storage and backups are available in our cloud-specific installation guides:

Backup and restore

The following instructions are specific to backing up and restoring the sourcegraph databases in a Docker Compose deployment. These do not apply to other deployment types.

WARNING: Only core data will be backed up.

These instructions will only back up core data including user accounts, configuration, repository-metadata, etc. Other data will be regenerated automatically:

  • Repositories will be re-cloned
  • Search indexes will be rebuilt from scratch

The above may take a while if you have a lot of repositories. In the meantime, searches may be slow or return incomplete results. This process rarely takes longer than 6 hours and is usually much faster.

Back up sourcegraph databases

These instuctions will back up the primary sourcegraph database the codeintel database.

  1. ssh from your local machine into the machine hosting the sourcegraph deployment
  2. cd to the deploy-sourcegraph-docker/docker-compose directory on the host
  3. Verify the deployment is running:
docker-compose ps

  1. Stop the deployment, and restart the databases service only to ensure there are no other connections during backup and restore.
docker-compose down
docker-compose -f db-only-migrate.docker-compose.yaml up -d
  1. Generate the database dumps
docker exec pgsql sh -c 'pg_dump -C --username sg sg' > sourcegraph_db.out
docker exec codeintel-db -c 'pg_dump -C --username sg sg' > codeintel_db.out
  1. Ensure the sourcgraph_db.out and codeintel_db.out files are moved to a safe and secure location.

Restore sourcgraph databases

Restoring sourcegraph databases into a new environment

The following instructions apply only if you are restoring your databases into a new deployment of sourcegraph ie: a new virtual machine

If you are restoring a previously running environment, see the instructions for restoring a previously running deployment

  1. Copy the database dump files, into the deploy-sourcegraph-docker/docker-compose directory.
  2. Start the database services
docker-compose -f db-only-migrate.docker-compose.yaml up -d
  1. Copy the database files into the containers
docker cp sourcegraph_db.out pgsql:/tmp/sourcegraph_db.out
docker cp codeintel_db.out codeintel-db:/tmp/codeintel_db.out
  1. Restore the databases
docker exec pgsql sh -c 'psql -v ERROR_ON_STOP=1 --username sg -f /tmp/sourcegraph_db.out sg'
docker exec codeintel-db sh -c 'psql -v ERROR_ON_STOP=1 --username sg -f /tmp/condeintel_db.out sg'
  1. Start the remaining sourcegraph services
docker-compose up -d
  1. Verify the deployment has started
docker-compose ps

Restoring sourcegraph databases into an existing environment

  1. cd to the deploy-sourcegraph-docker/docker-compose and stop the previous deployment and remove any existing volumes
docker-compose down
docker volume rm docker-compose_pgsql
docker volume rm docker-compose_codeintel-db
  1. Start the databases services only
docker-compose -f db-only-migrate.docker-compose.yaml up -d
  1. Copy the database files into the containers
docker cp sourcegraph_db.out pgsql:/tmp/sourcegraph_db.out
docker cp codeintel_db.out codeintel-db:/tmp/codeintel_db.out
  1. Restore the databases
docker exec pgsql sh -c 'psql -v ERROR_ON_STOP=1 --username sg -f /tmp/sourcegraph_db.out sg'
docker exec codeintel-db sh -c 'psql -v ERROR_ON_STOP=1 --username sg -f /tmp/condeintel_db.out sg'
