VOLUME from Dockerfile is not overwritten

/kind bug

Description

I want to run the official teamspeak image. I want to overwrite the data directory with a directory of my own. Neither -v nor --mount will overwrite the VOLUME from the Dockerfile. Podman run will always create a volume. I do not run podman rootless.

Steps to reproduce the issue:

podman run --user 9987:9987 \
 --mount type=bind,src=/mnt/HC_Volume_4317526/teamspeak/data,target=/var/ts3server \
 -v /etc/teamspeak/:/var/run/ts3server/ \
 -p 9987:9987/udp \
 -e TS3SERVER_LICENSE=accept \
 --name teamspeak \
 --network podstack \
 --ip 10.90.0.5

Using -v produces the same result

podman run --user 9987:9987 \
 -v /mnt/HC_Volume_4317526/teamspeak/data:/var/ts3server \
 -v /etc/teamspeak/:/var/run/ts3server/ \
 -p 9987:9987/udp \
 -e TS3SERVER_LICENSE=accept \
 --name teamspeak \
 --network podstack \
 --ip 10.90.0.5

Describe the results you received:

Only the directory /var/run/ts3server is bind mounted to the host:

podman inspect teamspeak | jq '.[0].Mounts'

Describe the results you expected:

I expected to both /var/run/ts3server and /var/ts3server to be bind mounted to the host

I'll take this one

Can you provide the name of the image being used in the examples here? I can't reproduce with Podman 1.8.0 trying to mount over an image volume in a custom-built image, so it might be specific to this image.

[mheon]

Actually, just a podman inspect of the image would help a lot... My initial suspicion is that there's something slightly different about this volume mount (trailing / maybe? Something messing up our normal comparison) and inspect should tell us that path

Hey, Don't have access to my terminal currently, but it was this image https://hub.docker.com/layers/teamspeak/library/teamspeak/3.11.0/images/sha256-c6bc812dfa39c58ce35d8f742acee51fc33ab6509c1824d071be732b24a17875?context=explore And you are right it included a trailing / in the volume. I added trailing slashes in the `-v` parameter yesterday . No effect. Matthew Heon <notifications@github.com> schrieb am So., 16. Feb. 2020, 01:25:
