Hm. That doesn't really sound bad. Thanks man, I guess I will take some time to read into it. Currently on proxmox, but AFAIK it does containers too.
It's really not! I migrated rapidly from orchestrating services with Vagrant and virtual machines to Docker just because of how much more efficient it is.
Granted, it's a different tool to learn and takes time, but I feel like the tradeoff was well worth it in my case.
I also further orchestrate my containers using Ansible, but that's not entirely necessary for everyone.
I only use like 10 VMs, guess there's no need for overkill with additional stuff. Though I'd like a gui, there probably is one for docker? Once tested a complete os with docker (forgot the name) but it seemed very unfriendly and ovey convoluted.
There's a container web UI called Portainer, but I've never used it. It may be what you're looking for.
I also use a container called Watchtower to automatically update my services. Granted there's some risk there, but I wrote a script for backup snapshots in case I need to revert, and Docker makes that easy with image tags.
There's another container called Autoheal that will restart containers with failed healthchecks. (Not every container has a built in healthcheck, but they're easy to add with a custom Dockerfile or a docker-compose.)
Thanks for the tips! But did i get it right here? A container can has access to other containers?
The Docker client communicates over a UNIX socket. If you mount that socket in a container with a Docker client, it can communicate with the host's Docker instance.
It's entirely optional.
Ah okay. Sounds safe enough. Thanks again :-)
Of course!
