From what I have seen, rootless podman seems to take more effort (even if marginal) than rootful one. I want to make a more informed decision for the containers, so I would like to ask.
- What is a rootless podman good for? How much does it help in terms of security, and does it have other benefits?
- One of the benefits commonly mentioned is for when container is breached. Then, running container on sudo-capable user would give no security benefits. Does it mean I should run podman services on a non-privileged user?
Thank you!
Rootless podman means that it is less likely to bork the system. It is also nice to have per user containers.
Another benefit is that you can run podman in a service user. This makes sandboxing much easier.
