Releasing a New Version

Only contributors can release new versions.

In order to release a new version, you must have Docker running locally. It is easiest if you are using a tool like Docker Machine, but as long as you are able to run the docker commands, everything is good.

Releasing a new version involves two steps: building and pushing. To build the new image, you issue a build command with the appropriate tag. The tag follows the format timberio/grease-builder:$(version).

The $(version) should be the current version number. The version number should be incremented based on Semantic Versioning specifications.

To build the new image, use the following command from the directory:

docker build -t TAG ./

replacing TAG with the appropriate tag. Once the image has successfully built, you can push the image to the repository using the following command:

docker push TAG

replacing TAG with the appropriate tag. Note that in order to do this you must be logged in and have write permissions on the timberio/grease-builder image in DockerHub.
