11:14 a.m.
I'm new to podman, and fairly new to containers in general, so any advice is
appreciated.
I'm running rootless podman in an environment with very little space allocated to
/home. To get around this, I'd like to set up storage for my containers in a directory
outside of my home while still running rootlessly. I'd prefer not to have the default
location for container storage changed for all rootless users if possible (i.e. don't
want to change /etc/containers/storage.conf if I can help it), I just want to override the
defaults for a single user.
My understanding is that I could accomplish this by creating a local config file for my
login and changing the locations of runroot and graphroot to the paths I want podman to
write container data to. So I created a file ~/.config/containers/storage.conf (it
didn't exist previously) and added the following minimal configs:
[storage]
driver = "overlay"
runroot = "/run/user/999"
graphroot = "/opt/resources/podman/containers/storage"
[storage.options]
mount_program = "/usr/bin/fuse-overlayfs"
After creating my the config file above though, none of my podman commands work running as
my user login. E.g doing
podman info
Gives me the following error:
Error: mkdir /run/containers/storage: permission denied
It seems like podman is ignoring my user-specific config file and using the runroot path
specified in /etc/container/storage.conf (which is set to /run/containers/storage), which
is what I'm trying to avoid. I can restore rootless podman functionality by deleting
my user-specific storage.conf file and reverting back to the default settings, but that
doesn't get me any closer to fixing my issue.
Details:
OS: RHEL 8.4
Podman Version: 3.2.3

If you have root permissions on this system, why not bind mount your
large storage to your homedir?
But this does look like a bug. Could you cehck if podman3.4 has this
problem?
Podman 3.3 was just released in RHEL8.5

Many thanks, Dan and Pavel. I will see about getting access to a dev
environment where I can try out 3.4, since I'm keen to see if this is
currently possible in podman.
Bind mounting some additional storage into my home is an option if needed,
and I had considered going this route. For this particular application, my
goal was to eventually surrender my root permissions entirely and have
everything running with as minimal privs I can get away with.
