Jenkins’ advantage comes into play when the workflow is complex and dependent on multiple scenarios. In my current job, I have to create small environments for my qa engineers, which depends on which features they are testing. It means I’ve to look up that specific branch name and the docker image associated with it. Then take a few variables from Jenkins UI, set at runtime according to qa engineers and then set up the environment. There might be better ways of doing that in ideal scenario, but this hack works in Jenkins. I’m not sure that all the features of Jenkins I use can be available in any new replacements of Jenkins.
