You should also clarify that you pulled your statements out of your butt to look edgy. Everyone in every team I worked for the last ten years use docker. Docker is old tech. If you and your cavemen devs ignore what it is, that's your problem.

I hit the nail hard considering you went ballistic.

Keep making up stories how you use best practices only and do everything by the book.

I bet my testicles that in similar fashion, you are lecturing others on IAM while you store credentials in notepad and swnd it via mail. And lectures about backup, RTO, RPO, while you don't have any systematic backup and never heard about use of geographicaly isolated backup, or WORM.

Docker is old tech, yes, doesn't mean every dev in the world uses it. They don't. Jails/zones are even older (hell a chroot). Did developers all use those before due to them being 'old tech'. No.
