Debugging Openshift Docker Registry using Visual Studio Code
Overview Red Hat has augmented docker's registry with some enhancement before deploying it in Openshift cluster. In some cases we might want to debug it, to find out reasons why some stuff doesn't work or for educational purposes. In this post we will describe steps required to do debugging for the docker registry (a.k.a docker distribution) from Visual Studio Code. We are going to run the openshift docker registry in a separate deployment config. Repository identification First, docker registry is created using Go Language; and in this case, the source code for the enhanced docker registry lives in github repository https://github.com/openshift/origin for some versions and in https://github.com/openshift/docker-distribution for later versions. In this post I will use the version in openshift 3.6 ( https://github.com/openshift/origin/tree/v3.6.1 ) because of selfish reasons our sandbox/development openshift cluster uses this version. The main source code file lives...
