The only argument I have heard for Docker that makes any sense to me lately is that when your developers are using macOS and your servers run Linux, it’s nice to have dev/prod parity. Practically I think this speaks to either using better development environments, or writing code that is much more portable than what people try to get away with.
Get something running in any environment really quickly because it is already a separate environment
Nobody has to deal with package managers messing up their system, or have to deal with package manager managers that lets them switch between different versions of a package manager just so they can run some obscure dependency before getting to the project
