That's not all that docker or any containerization gives you. For most people I've seen it's about infrastructure as code and quickly deploying Dev/staging environments. Yes you can do the same with ansible or terraform but what if you only want to test locally? Do you really want to wait for a VM to be carved out? Or just run a command and have things come up?

Also, not needing to support log extraction or deal with unit scripts or SSH or bin packing applications onto VMs or mucking with ansible/packer/etc. Personally I don’t want to spend my time on needlessly tedious, uninteresting problems.
