--volume is not a valid flag for a pod.

You can specify it to podman create or podman run

I've closed the issue but please feel free to comment further

@giuseppe What do you mean by --volume is not valid for a pod ? Do you mean that the following command isn't expected to work ?

$ podman pod create -p 8080:8080 --name mypod --volume ./html:/var/www/html:z

Have a look at Podman in Action by Daniel Walsh, Chapter 4.2, page 80. Now, if you want to close issues, be my guest but the most important is to fix them.

Yes, podman create --volume exists but Podman v3.4.4 is too old. The flag was added by #11409 which made it into Podman 4.0.0.

[nicolasduminil]

@vrothberg I'm not talking about podman create ... --volume ... but about podman pod create ... --volume ... And what do you mean by "Podman 3.4.4 is too old" ? Too old for what ? To be able to run the mentioned command ? The documentation instructs to install podman by running apt-get install podman and, doing that, podman 3.4.4 gets installed.

[vrothberg]

@nicolasduminil, apologies, I wrote create --volume but meant pod create --volume. The latter was added by #11409 and is only available with Podman v4.0 and after.

The documentation instructs to install podman by running apt-get install podman and, doing that, podman 3.4.4 gets installed.

That seems like an issue in the Podman book. @rhatdan can you take a look? I guess the book requires Podman 4.0.

More recent versions of Ubuntu ship newer versions of Podman. Maybe that's an alternative.

sorry, my mistake as I've assumed --volume does not work with pod. As @vrothberg pointed out though, it requires a new version of Podman so there is nothing we can do upstream to address it, it must be fixed by the distro to provide an updated version.

[rhatdan]

Yes the book assumes podman 4.0 or later.
