devth/helm repository overview

⁠helm-docker

⁠Usage

This Docker image includes helm along with:

• gcloud
• kubectl
• envsubst
• jq
• vals⁠

And helm plugins:

• viglesiasce/helm-gcs.git
• databus23/helm-diff
• helm/helm-2to3

⁠Docker

Docker images are automatically built on Docker Hub⁠:

• Docker tags correspond to Helm release⁠ versions.
• latest is always the latest fully released version (non-beta/RC).
• master is always the latest commit on master.

⁠Building

To test a local build:

docker build -t devth/helm .

⁠Release procedure

Use the following to:

• Bump VERSION in the Dockerfile⁠
• Commit and create tag matching the version

NB: the sed syntax works with MacOS built-in sed.

gh issue list
VERSION=v3.6.3
ISSUE=124
# use GNU sed
sed -i "3s/.*/ENV VERSION $VERSION/" Dockerfile
git diff # ensure it looks good
git commit -am "Bump to $VERSION; fix #$ISSUE"
git tag $VERSION
git push && git push --tags

Close an issue without fixing it:

gh issue close 109

Optionally test building the image before pushing:

docker build .

⁠Re-release

To re-build a particular tag we need to delete the git tag locally and remotely:

git push origin :$VERSION
git tag -d $VERSION

Then re-tag and push:

git tag $VERSION
git push --tags
