Auto-trigger docker build for kubernetes helm when new release is announced
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 alpine/helm:3.1.1
If you need run kubectl with helm together, please use another image alpine/k8s

# Run helm with special version. The tag is helm's version

Mostly it is used during CI/CD (continuous integration and continuous delivery) or as part of an automated build/deployment
- 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
alpine/helm:latestand push to hub.docker.com
