- x86x87 4y agoContainers are not regular processes. One could argue that you can have a container without any process in it. A container is an abstract idea that normally comes together through the synergy of [at least] cgroups, namespaces and overlay filesystems.
- sureglymop 4y agoThey are regular linux processes, you can find them in /proc or display them with ps... Croups, namespaces etc are Linux features that can be used with any process. But i guess i see now what you are saying. That it's a "meta" term for that idea of abstraction.
