[podman] path to fuse-overlayfs

[tobwen]

Is this a BUG REPORT or FEATURE REQUEST? (leave only one on its own line)

/kind feature

Description
Right now, it's not possible to point to the binary of fuse-overlayfs; neither via CLI, nor via config. It only works in PATH-variable.

[giuseppe]

you can specify its value in ~/.config/containers/storage.conf:

  [storage.options]
    mount_program = "/usr/bin/fuse-overlayfs"

and you can also override from the command line using --storage-opt

and you can also override from the command line using --storage-opt

Tried so, didn't work. Something with key/value. Can't remember, will pull the new PR and repost.

what command have you tried?

[tobwen]

See first line :-)

[giuseppe]

could you try something like:

podman --storage-opt='overlay.mount_program=/path/to/fuse-overlayfs' ...

[tobwen]

This one works. Thanks!

Maybe you could add it as an example in man?

[TomSweeneyRedHat]

Working on the man page addition.

[TomSweeneyRedHat]

I"m assuming this part '--stoge-opt' s/b '--storage-opt'

Yeah. Sorry for that, but it seems as this needs #2659
