Kubernetes How-to Guides

We have a number of guides to help you deploy Gaffer on Kubernetes.

Versioning

Each of our images will be tagged in DockerHub with the version of the software they represent. Every release, we update the image for that tag and add a new release which has the corresponding git tag.

So if we tag this code in git as 1.0.0 and publish the resulting gaffer image at gaffer version 1.11.0, the following images would be pushed to Docker Hub:

• gchq/gaffer:latest
• gchq/gaffer:1
• gchq/gaffer:1.11
• gchq/gaffer:1.11.0
• gchq/gaffer:1.11.0_build.1.0.0

Note that we maintain mutable versions of latest, as well as the major, minor and bugfix versions of Gaffer. If you want to ensure that your image will never change when doing a pull from docker, make sure to use the version with the git tag in the build metadata.

This process is automated by Github actions.
