Failed to set up id mapping.
I ran into the same error recently but I was increasing the default map
size. I had to:
1. Stop the container
2. Make the container privileged
3. Start then stop the container
4. Make the container unprivileged
After that it worked with the new ID's in the unprivileged container
I made the container privileged and set both UID/GID mappings. The
container started and the ownership of files is correct. Resetting
the container to unprivileged reverts back to the error.
I'm guessing that remapping UID/GID 48 is not permitted in a
non-privileged container.
I would guess the same thing
Is there a better way to do this?
I would also be interested if there is a better way to do this as the
method I listed above may not always be possible for some situations.
Anyone?
