Release Docker

This is the task to release all services for the networknt organization to the docker hub. It first checkout repositories into a workspace and switch to the release branch defined in the release-docker.yml file. If the workspace exists, then it will switch to the release branch and run git pull origin (release-branch) to ensure the codebase is the same as remote.

Then the release process is started with the following step for each repository.

• check out release branch or pull the latest from the release branch.
• generate CHANGELOG.md from local release branch and github.com API.
• check in the CHANGELOG.md to the release branch
• run mvn clean install to build the service
• build docker image with the Dockerfile in each service
• push the docker images to the docker hub
• read CHANGELOG.md for the current release into a StringBuffer.
• call GitHub API to create a new release note and tag

Note that before release, all projects should be built successfully in the release branch by [develop-build][]. After the release, you might need to change the GitHub release a little bit to add the upgrade guide.

Here is an example of the release-docker.yml config file for networknt projects in the master branch.
