>Seriously though, knowing docker really well is more likely to improve my career
Unfortunately true -- for now. However, your career would be even better served by gaining experience in non-fad technologies.
Also, "career development" is an offensive reason to deploy a technology for your employer. I recognize that it is common, but it's still improper to prioritize resume points over the employer's long-term stability and interests. Personally, when a candidate gives off that vibe to me, I pass on them every time.
>Does Ansible provide isolation of different dev environments? I think not.
I don't understand. Anything you can script in Docker, you can script in Ansible. They both allow the user to pass in arbitrary shell commands and execute anything they want on the target. How does this not accommodate "isolation of different dev environments"?
Maybe you mean that since you can execute a Docker container on your Mac, you don't need to set up a "local" env? Docker transparently uses a virtual machine to execute a Linux kernel on the Mac. You can execute an Ansible script on a normal VM the same way (optionally using something like Vagrant to give more simplistic, Docker-like (which is really Vagrant-like) CLI management).
