Describe the bug
Running
podman run --rm -p 8080:80 --name octoprint docker.io/octoprint/octoprint:latest
works without problems. When I add --read-only
to the command, I get
[s6-init] making user provided files available at /var/run/s6/etc...exited 0.
[s6-init] ensuring user provided files have correct perms...s6-chown: fatal: unable to chown /var/run/s6/etc/cont-init.d/v3-dir-structure-check: Read-only file system

s6-supervise (child): fatal: unable to exec run: Permission denied
s6-supervise octoprint: warning: unable to spawn ./run - waiting 10 seconds
[services.d] done.
That is expected with s6 and my understanding is that S6_READ_ONLY_ROOT=1
environment variable should fix that.
Indeed,
podman run --rm -p 8080:80 --name octoprint --read-only -e S6_READ_ONLY_ROOT=1 docker.io/octoprint/octoprint:latest
gives me a working OctoPrint UI on host's 'http://localhost:8080/' URL ... except the output of the container now shows a stream of
MJPG Streamer Version.: 2.0
i: Using V4L2 device.: (null)
i: Desired Resolution: 640 x 480
i: Frames Per Second.: -1
i: Format............: JPEG
i: TV-Norm...........: DEFAULT
i: init_VideoIn failed
messages.
I even tried to add an explicit -e ENABLE_MJPG_STREAMER=false
but that does not help either.
Container Details
please run `docker inspect --format '{{ index .Config.Labels "org.opencontainers.image.created"}}' octoprint/octoprint:<tag_you_are_using>' and list the date returned.
