Currently I’m running some services though Docker on a Proxmox VM. Before I had Proxmox, I thought containers were a very clean way of organizing my system. I’m currently wondering if I can just install the services I always use on the VM directly. What are the pros and cons of that?
Personally, I always like to use containers when possible. Keep in mind that unlike virts, containers have very minimal overhead. So there really is no practical cost to using them, and they provide better (though not perfect) security and some amount of sandboxing for every application.
Containers mean that you never have to worry about whether your VM is running the right versions of certain libraries. You never have to be afraid of breaking your setup by running a software update. They’re simpler, more robust and more reliable. There are almost no practical arguments against using them.
And if you’re running multiple services the advantages only multiply because now you no longer have to worry about running a bespoke environment for each service just to avoid conflicts.
