Releasing Loki Build Image

The loki-build-image is the Docker image used to run tests and build Grafana Loki binaries in CI.

The build and publish process of the image is triggered upon a merge to main if any changes were made in the folder ./loki-build-image/.

To build and use the loki-build-image:

Step 1

1. create a branch with the desired changes to the Dockerfile
2. update the version tag of the loki-build-image pipeline defined in .drone/drone.jsonnet (search for pipeline('loki-build-image')) to a new version number (try to follow semver)
3. run DRONE_SERVER=https://drone.grafana.net/ DRONE_TOKEN=<token> make drone and commit the changes to the same branch
   1. the <token> is your personal drone token, which can be found by navigating to https://drone.grafana.net/account.
4. create a PR
5. once approved and merged to main, the image with the new version is built and published
   • Note: keep an eye on https://drone.grafana.net/grafana/loki for the build after merging (example)

Step 2

1. create a branch
2. update the BUILD_IMAGE_VERSION variable in the Makefile
3. run loki-build-image/version-updater.sh <new-version> to update all the references
4. run DRONE_SERVER=https://drone.grafana.net/ DRONE_TOKEN=<token> make drone to update the Drone config to use the new build image
5. create a new PR
