Guided Exercise: Volume Mounting

[biltonbilmes]

Hallo Team,

I"m trying to understand what i"m missing in 

Guided Exercise: Volume Mounting

I see we mount the ~/www using Z option but it fails because of lack of directory listing permission.

Then we create the volume html-vol, import the tar file and then run without using Z. In my case it is show same error i.e. directory listing permission.

am I"m missing something. What is weird is, if I use Z option it works

podman run --name podman-container-name --rm -it -p 8000:8000 --volume vol-html:Z registry.ocp4.example.com:8443/redhattraining/podman-python-server

but without Z it fails

I might be wrong, but i think there is typo in the manual. One must always use 'Z'

Hello @biltonbilmes 

1) Please, looks at man:

--volume, -v=[[SOURCE-VOLUME|HOST-DIR:]CONTAINER-DIR[:OPTIONS]]

2) Please, be accurate:

[student@workstation persisting-mounting]$ podman run -ti --rm --name podman-server -p 8000:8000 --volume html-vol:/server registry.ocp4.example.com:8443/redhattraining/podman-python-server

So you miss /server directory inside container. In case with ":Z" Z is correct option, but /server is missed, so Z take place of /server;  in case  you do not use ":Z" html-vol suppose to be directory inside container. Both cases are wrong.

Good luck

Because Podman manages the volume, you do not need to configure SELinux permissions.
