shouldn't the current directory be the default context for "podman build"?
by Robert P. J. Day 12 Dec '24

12 Dec '24

"man podman-build" suggests that the context argument is optional: SYNOPSIS podman build [options] [context] podman image build [options] [context] ... If no context directory is specified, then Podman will assume the current working directory as the build context, which should contain the Containerfile. but if i have a directory with nothing but a Containerfile, i get: $ podman build Error: no context directory specified, and no containerfile specified $ OTOH, specifying context of current directory: $ podman build . STEP 1: FROM alpine:latest ... etc etc ... thoughts? rday

rootless podman, docker-credential-gcloud, and snaps
by Ioan Rogers 21 Jun '21

21 Jun '21

Hi, I'm on Ubuntu, and I've recently encountered an issue when trying to use rootless podman with the docker-credential-gcloud helper installed via snap. This works fine when using the official google-cloud-sdk apt packages, and it used to work with snap packages until last October. Here's what I see now: ``` $ podman pull gcr.io/private/image Trying to pull gcr.io/private/image... 2021/02/01 13:19:17.474248 cmd_run.go:994: WARNING: cannot create user data directory: cannot create "/root/snap/google-cloud-sdk/166": mkdir /root/snap: permission denied cannot create user data directory: /root/snap/google-cloud-sdk/166: Permission denied error getting credentials - err: exit status 1, out: `` Error: unable to pull gcr.io/private/image: Error initializing source docker://gcr.io/private/image:latest: error getting username and password: error getting credentials - err: exit status 1, out: `` ``` So it looks like the credential helper is being executed as root now. I'm not sure in which component the problem lies, or where I should file an issue. Any pointers would be appreciated. Thanks Ioan Rogers Sent with ProtonMail Secure Email.

Hi, I have a problem mapping a cifs network share to a container. It's an auto-mount and from the /etc/auto.mnt I can see it's mounted with: -fstype=cifs,rw,noperm,vers=3.0 The mount is attached to the /mnt/share-name I run image of the container with: sudo podman run --pod pod-name --detach --name container-name -v /mnt/share-name:/usr/src/app/share:rw,z ......... I get: Error: failed to set file label on /mnt/share-name: operation not supported Wonder if anybody could help me and point me to the right direction. Thanks

Hi guys I'm trying a popular image, perhaps very popular(not sure if with podman consumers though) off which a rootful container produces no logs. I've tried podman vers 2.0 & 3.1, with the same results. Adding debug to: -> $ podman container restart cni-net.disc --log-level=debug ...

overlayfs driver VS images - overlayfs: unrecognized
by lejeczek 27 Apr '21

27 Apr '21

Hi guys. First thing which came to mind was to try driver newer version of the driver or newer kernel all together - when I got this upon container creation: .... overlayfs: unrecognized mount option "volatile" or missing value overlayfs: unrecognized mount option "volatile" or missing value .... But before I do that - would there be a way to tamper with the image perhaps and/or other bits involved in order to get get rid of the problem? many thanks, L.

I've never seen this error. Is this a default install of RHEL 8.3? Try adding a new user to the system and running the podman with that new user.
