Cross-Cluster Image Promotion Techniques

Many organizations decide to have multiple container clusters to segregate different environments. This leads to the problem of how to move container images created in one cluster to another cluster. The need to move images across cluster typically arises when one needs to implement a promotion process where the next environment for the given app is not in the same cluster as the current environment. This situation is common regardless of the container cluster manager and delivery pipeline being used. In this article, I will assume using OpenShift as the container cluster manager and Jenkins as the delivery pipeline tool.
