kubernetes helm

Auto-trigger docker build for kubernetes helm when new release is announced.

NOTES

The latest docker tag is the latest release version (https://github.com/helm/helm/releases/latest)

Please avoid to use latest tag for any production deployment. Tag with right version is the proper way, such as renaultdigital/helm:3.1.1

Same image as alpine-docker with:

• curl
• helm-push: latest
• yq: v3.3.0

    -v ~/.cache/helm:/root/.cache/helm \

Why we need it

Mostly it is used during CI/CD (continuous integration and continuous delivery) or as part of an automated build/deployment

The Processes to build this image

• Enable Travis CI cronjob on this repo to run build daily on master branch
• Check if there are new tags/releases announced via Github REST API
• Match the exist docker image tags via Hub.docker.io REST API
• If not matched, build the image with release version and push to https://hub.docker.com/
• Get the latest version from https://github.com/helm/helm/releases/latest, pull the image with that version, tag as renaultdigital/helm:latest and push to hub.docker.com
