A ranted on my blog about why I don't like Docker. Or Podman.
@liw For my requirements, this.
'I prefer to use virtual machines. They’re slower to set up, and start up a little slower too, but they’re convenient for me, and I *understand* them well.
They also behave more like a real Linux system running on bare metal hardware than containers do.
There are fewer limitations that get in my way'.
I'm not anti-Docker just more comfortable using VM's I can backup, clone, snapshot.
For lightweight, disposable services I see why Docker is attractive.
