By default codefresh on-premises uses codefresh builders to run your builds. In case you configured more than one builder, you might need to know on which builder pod specific build was run on for debug purposes for example in case of networking issues in your k8s cluster
One of the ways you can use for this purpose is to output the builder pod name to the build logs so it can be easily found there in future.
You just need to add
echo $CF_HOST_NAME to the commands list of one of the freestyle steps in the pipeline for which you need to track the builder name it runs on.
