This made me laugh. Configuration management systems like ansible, chef, salt, and puppet only exist because people wanted to manage a large numbers of systems and keep them consistent and replaceable, i.e treat them like cattle instead of pets. They were born out of the pets vs cattle analogy.
I realize containerization has taken that a step further but it's funny to hear someone talk about these tools like they're something archaic.
Probably more accurate to say "mutable" vs "immutable".
Harder to have pets in immutable if it's actually immutable.
If you want to replace them why would you not use a golden image? The same thing goes for VMs, not only containerized. You can sit there and wait for ansible to run, or just have your image come up immediately with what you need. It makes it take longer with 0 benefit.
And where do you think the golden images come from? The steps must be reproducible, versioned, audited, scripted and in the third hands of outsourced minions with 8 or 12h time lapse.
The golden rule of CICD does it survive if you're visited by truck-kun?
