tmpfs options are not parsed

[LordAro]

According to the docs, I should be able to specify some options when creating a tmpfs mount - https://docs.podman.io/en/latest/markdown/podman-run.1.html#tmpfs-fs

I've specified these in the nomad job file as:

        tmpfs = [
          "/tmp/csi/keys:rw,size=1000k"
        ]

But it seems not to be working, when I podman container inspect directly I get:

...
               "Tmpfs": {
                    "/tmp/csi/keys:rw,size=1000k": "rw,rprivate,nosuid,nodev,tmpcopyup"
               },
...

Which rather suggests that it's mounted a folder named /tmp/csi/keys:rw,size=1000k rather than /tmp/csi/keys

• nomad 1.6.2
• nomad-driver-podman 0.5.1
• podman 4.3.1

I'm very new to this, so maybe I'm missing something obvious...

Hi @LordAro 👋

Thanks for the report. I think we're missing logic here to split the input string into destination and options.

nomad-driver-podman/driver.go

Lines 1359 to 1365 in 259a211

	for _, dst := range driverConfig.Tmpfs {
	bind := spec.Mount{
	Destination: dst,
	Type: "tmpfs",
	}
	binds = append(binds, bind)
	}

I will try to to push a fix next week.

Just tripped over this myself tonight trying to get the Ceph CSI driver running, looks like the parser is still doing the simple operation here.
