Publishing a release

Warning

These steps are currently structured in a manner that is convenient for Mathesar developer but leaves a window open during which the documentation will be out of sync with other assets required for installation and upgrades.

For example: the docs get published as soon as the release PR is merged into master. At that point the tag won’t yet exist in GitHub (meaning readers won’t be able to download the referenced docker-compose file) and the image won’t yet exist on DockerHub.

We would like to improve this process. But in the mean time, be sure to follow these steps quickly so as to reduce the duration of this “out of sync” window.

1. Set a VERSION variable in your shell

   Run this command to set a local variable within your shell to the version number of the release you’re making.

   VERSION=1.2.3 # ⚠️ CUSTOMIZE THIS
   

   Note

   Do not prefix the version with v.

2. Merge the release notes PR (if not yet done)

   This should merge the release notes file into the release branch.

3. Merge the release PR

   This should merge the release branch into master.

   Before moving on, ensure the release branch is deleted within GitHub after merge. This should happen automatically after merging. The PR should show an entry in the activity timeline like:

   seancolsen deleted the 0.1.5 branch 1 minute ago

4. Create the tag

   Locally tag the commit you’ve just merged with the version number of the release. Then push to GitHub.

   git checkout master
   git pull
   git branch -d $VERSION
   git tag $VERSION
   git push origin $VERSION
   

   A draft release will be automatically created on GH once this tag is pushed.

5. Publish Docker images

   1. Log in to DockerHub

      docker login
      

      (Use your personal Docker credentials. Your personal Docker account will need to be a member of our mathesar Docker org.)

   2. Locally clone the repo into a clean directory and go there.

      REPO_DIR=$(pwd)
      CLEAN_REPO_DIR=$(mktemp -d)
      cd $CLEAN_REPO_DIR
      git clone -b master --single-branch --no-tags "$REPO_DIR" .
      

      (This ensures that files which are ignored by git don’t end up in the Docker image.)

   3. Run the following commands:

      docker buildx build \
        -t mathesar/mathesar-caddy:$VERSION \
        -t mathesar/mathesar-caddy:latest \
        --builder=cloud-mathesar-release-builder \
        --platform=linux/amd64,linux/arm64 \
        --push \
        -f Dockerfile.caddy .
      
      docker buildx build \
        -t mathesar/mathesar-prod:$VERSION \
        -t mathesar/mathesar-prod:latest \
        --builder=cloud-mathesar-release-builder \
        --platform=linux/amd64,linux/arm64 \
        --push .
      

      These commands build, push, and tag the images as latest.

   4. Clean up

      cd "$REPO_DIR"
      rm -rf $CLEAN_REPO_DIR
      docker logout
      

6. Update the draft GitHub release and publish it

   gh release edit \
     --latest \
     --title "Version $VERSION (alpha release)" \
     --notes "__[Release notes](https://docs.mathesar.org/releases/$VERSION/)__" \
     --draft=false \
     $VERSION
   

7. Merge master into develop

   GitHub will automatically create a PR for this. Find it and merge it.
