Update

Pull the latest images, restart, done. Migrations run on boot.

Update to latest

terminal
docker-compose pull app executor
docker-compose up -d app executor

Database schema migrations apply automatically on first request after boot. Data in Docker volumes is preserved.

Pin a version

Replace latest in docker-compose.yml with a tag:

docker-compose.yml
image: ghcr.io/mlab-sh/ir.mlab.sh:v0.9.0

Rollback

If a release introduces a regression: re-pin to the previous tag, docker-compose up -d app executor. Schema rollbacks are not automatic — restore the MySQL/ClickHouse volumes from backup if a migration is involved.

Always back up before major upgrades. Snapshot the mysql_data and clickhouse_data volumes (or run the logical dump from the installation page) before bumping a major version.
