I work mostly with deployments and updates to our environments, and the most helpful thing my developers can do for me is provide validation steps to confirm the state after each change.

We've caught issues ranging from expired passwords, missing files / files with incorrect permissions / write failures, sync issues and other obscure gotchas.

Catching a failed step during deployment can sometimes prevent a huge rollback effort and save a lot of time.

What about containerzired deployment? Isn't Docker the silver bullet? Or at least will it allow to mitigate your issues easily?

Docker alone isn't remotely close to comprehensive test driven infrastructure.
