Management Operations
Manage storage
The Sourcegraph Docker Compose yaml file 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:
- Storage and backups for Amazon Web Services
- Storage and backups for Google Cloud
- Storage and backups for Digital Ocean
Access the database
The following command allows a user to shell into the Sourcegraph database container and run psql to interact with the container's postgres database:
docker exec -it pgsql psql -U sg #access pgsql container and run psql docker exec -it codeintel-db psql -U sg #access codeintel-db container and run psql
Database Migrations
The frontend container in the docker-compose.yaml file will automatically run on startup and migrate the databases if any changes are required, however administrators may wish to migrate their databases before upgrading the rest of the system when working with large databases. Sourcegraph guarantees database backward compatibility to the most recent minor point release so the database can safely be upgraded before the application code.
To execute the database migrations independently, follow the docker-compose instructions on how to manually run database migrations. Running the up (default) command on the migrator of the version you are upgrading to will apply all migrations required by the next version of Sourcegraph.
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.
Back up Sourcegraph databases
These instructions will back up the primary sourcegraph database and 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:

4\. 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
5\. 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
6\. Ensure the sourcegraph_db.out and codeintel_db.out files are moved to a safe and secure location.
Restore 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
3\. Copy the database files into the containers
docker cp sourcegraph_db.out pgsql:/tmp/sourecgraph_db.out docker cp codeintel_db.out codeintel-db:/tmp/codeintel_db.out
4\. 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'
5\. Start the remaining Sourcegraph services
docker-compose up -d
6\. Verify the deployment has started

7\. Browse to your Sourcegraph deployment, login and verify your existing configuration has been restored
Restore 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
2\. Start the databases services only
docker-compose -f db-only-migrate.docker-compose.yaml up -d
3\. Copy the database files into the containers
docker cp sourcegraph_db.out pgsql:/tmp/sourecgraph_db.out docker cp codeintel_db.out codeintel-db:/tmp/codeintel_db.out
4\. 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'
5\. Start the remaining Sourcegraph services
docker-compose up -d
6\. Verify the deployment has started

7\. Browse to your Sourcegraph deployment, login and verify your existing configuration has been restored
Monitoring
You can monitor the health of a deployment in several ways:
- Using Sourcegraph's built-in observability suite, which includes dashboards and alerting for Sourcegraph services.
- Using
docker psto check on the status of containers within the deployment (any tooling designed to work with Docker containers and/or Docker Compose will work too).- This requires direct access to your instance's host machine.
