Permissions on top level of mounted volume in rootless container
by Peter Upfold 12 Apr '21

12 Apr '21

Hello, I'm struggling a little with the permissions set on the top level directory of a volume that is mounted in a rootless container. My Containerfile: https://gist.github.com/PeterUpfold/2f63ad5341ffd9079bc2683a5bb2744c The top level directory of the volume mount, /var/www/html/websites/windows, ends up with root:nobody and 0755 permissions inside the container. I've seen similar issues on this list: Daniel Walsh's suggestion of `--annotation run.oci.keep_original_groups=1` seems to work beautifully to change the ownership of the volume folder in the container to be windowsnoob:windowsnoob, as I would want it, _if_ I'm doing `podman run`. However, I'm trying to create a pod as follows. Is it possible to have this permissions configuration work in this scenario? podman pod create -n windowsnoob -p 8081 podman build -t windowsnoob-fpm . podman create --name windowsnoob-fpm --pod windowsnoob -v /var/www/html/websites/windows:/var/www/html/websites/windows:Z,noexec,nodev,rw windowsnoob-fpm podman pod start windowsnoob At the moment, doing this and checking the permissions on the /var/www/html/websites/windows volume in the created container (via `podman exec -it [container] bash`) still shows the following: drwxr-xr-x. 2 root nobody 28 Feb 14 09:45 windows (Note that I can write to a subfolder already owned by windowsnoob:windowsnoob _inside_ the volume just fine — I don't believe this is an SELinux issue, or a permissions issue on anywhere except the top level of the volume mount!) Thank you for any insight you might be able to provide! Peter Upfold

unknown capability CAP_PERFMON
by lejeczek 06 Apr '21

06 Apr '21

Hi guys. My podman created a network, just with: -> $ podman network create /home/podmania/.config/cni/net.d/cni-podman0.conflist then created a pod: -> $ podman pod create --network cni-podman0 --hostname some ---name some then tried to create a container: -> $ podman run -it --pod=some --name some-nettols docker.io/pmietlicki/nettools ERRO[0000] error starting some container dependencies ERRO[0000] "container_linux.go:370: starting container process caused: unknown capability \"CAP_PERFMON\": OCI runtime error" Error: error starting some containers: internal libpod error Is that a limitation by design? I see that while run "rootless" and am on CentOS Stream with: podman-3.1.0-0.13.module_el8.5.0+733+9bb5dffa.x86_64 4.18.0-294.el8.x86_64 many thanks, L.

New Podman CVE: CVE-2021-20291
by Matt Heon 05 Apr '21

05 Apr '21

Hi, In the last few days, a new CVE affecting Podman, CVE-2021-20291, was made public. This vulnerability affects the containers/storage library and can cause a denial of service if the user pulls a specially-crafted image, causing most Podman commands to hang. The Podman team does not feel that this is a serious vulnerability, as any affected Podman image pull can be killed without adverse effect on other Podman processes and running containers. However, we still encourage all users to upgrade to the latest Podman release, Podman v3.1.0, which resolves the issue. Thanks, Matt Heon

I am trying to give my container its own IP address. I am using the macvlan and have it setup. Am I doing this wrong? [ameyer@podman01 ~]$ sudo podman run --privileged --ip 10.150.11.41 --mac-address 2A:7C:AA:ED:A2:AE --name=pihole --dns=1.1.1.1 -e TZ=America/Chicago -e SERVERIP=10.150.11.41 -e ServerIP=10.150.11.41 -e WEBPASSWORD=secret -e DNS1=1.1.1.1 -e DNS2=1.0.0.1 -e DNSSEC=true -e CONDITIONAL_FORWARDING=true -e CONDITIONAL_FORWARDING_IP=10.150.10.1 -e CONDITIONAL_FORWARDING_DOMAIN=lan -e TEMPERATUREUNIT=f -v pihole_pihole:/etc/pihole:Z -v pihole_dnsmasq:/etc/dnsmasq.d:Z docker.io/pihole/pihole ERRO[0002] Error adding network: failed to allocate all requested IPs: 10.150.11.41 ERRO[0002] Error while adding pod to CNI network "podman": failed to allocate all requested IPs: 10.150.11.41 Error: error configuring network namespace for container 6b7fa7c2d16a880388c835e6688484480bda0b3260c1a71fead835d0858bc7cb: failed to allocate all requested IPs: 10.150.11.41 [ameyer@podman01 ~]$

image signing
by Hendrik Haddorp 29 Mar '21

29 Mar '21

Hi, is OpenPGP the only supported image signing open supported by podman / skopeo or are there other options? Using OpenGPG works quite fine for me so far but in the end we are trying to sign an image using an IBM 4765 crypto card and so far have not figured out how this can play together. thanks, Hendrk

Podman Machine vs. Podman Machine
by Anders F Björklund 28 Mar '21

28 Mar '21

Hi all! I will rename Podman Machine (podman-machine) and Docker Machine (docker-machine) to avoid using the Red Hat and Docker trademarks and mixup with "podman machine". My new project ended up being called Ice Machine, since it's used with Floe Linux. <https://boot2podman.github.io/2021/01/24/reboot-new-project.html> Once the new feature stabilizes, I can add a link from the old web sites as well. Like from < https://podman.io/blogs/2019/01/14/podman-machine-and-boot2podman.html> Currently it says to use Vagrant and Fedora, rather than Podman and Fedora CoreOS <https://boot2podman.github.io/2020/07/22/machine-replacement.html> /Anders PS. The remaining projects will stay up, but are not further developed beyond Podman 1.9.3 and Docker 19.03 as presented in the "port-mortem. It was still used in previous versions of minishift and minikube, but has been forked and adapted to each project instead of being shared...
