Hi there!
I have no real issue with the changes, just one question: do you think that we should use the same envFrom clause in the case of initJob? The initcontainer is an option,. but not the default, and it would make sense for me to load the same envs in the job that does the migration.

@Demonsthere
You're right, it should be present for initJob as well. 👍
