Users will now be able to deploy our portainer agent on podman and connect to that via a portainer instance to manage the podman environment.

Known issues:

App Templates

Create new container with template – Error “Failure – name or ID cannot be empty”

Container

Stats (rootless) – Does not work because root privileges are required
Stats (rootful) – “error”
Podman-attach - Does not connect automatically
Recreate container (recreate) – Error “Failure – Unable to re-create container”
Pause – Only works for root container
Resume – Only works for root container
Duplicate / Edit error

Images

Import – Image is displayed locally with podman images but you can’t start a container with the image

Volumes

Browse existing volumes -> Does not show any files from the volume. Portainer shows error: Failure - open /var/lib/docker/volumes/NginxTestVolume/_data: no such file or directory

Events

Content of events : Shows “Unsupported event” as an event. i.e. the creation of a new container is shown as an “unsupported event”

Sweet! Is there a roadmap of some sorts which covers these issues?

Hi @wzzrd,

These are not currently scheduled for a release at this time, But we do see opportunity for these issues to be addressed as we grow our support for all container platforms. We do welcome feedback and contributions around podman.

Hi, I'm trying to run portainer on podman as root, but I always get the following error :
Error: cannot open sd-bus: No such file or directory: OCI not found

This happens when I try to run portainer as root. The command I'm trying is:
podman run -d -p 8000:8000 -p 9443:9443 --privileged --name portainer --restart=always -v /var/run/podman/podman.sock:/var/run/docker.sock -v portainer_data:/data docker.io/portainer/portainer-ce:latest

Does someone have a solution ? I found no mention of this error anywhere. I am running this as root on a fresh debian install.

@LeVraiRoiDHyrule

This should get you a little further:

podman run -d -p 8000:8000 -p 9000:9000 -p 9443:9443 --privileged --name portainer \
    --restart=always \
    -v /run/podman/podman.sock:/var/run/docker.sock \
    -v portainer_data:/data \
    cr.portainer.io/portainer/portainer-ce:latest

You can eliminate -p 9000 if you don't want http access. Note the difference in the volume mapping of the Podman socket.

Just trying out Portainer with Podman myself, and I'm seeing a few issues (running as root). "Failure - unable to find bridge plugin" seems to be the most significant, as I'm not able to get any data about my container networks.

Anyone figured out a fix for this?

Thanks for your answer. Unfortunately, I'm still getting the same error with this run command.

Are you able to launch other containers using Podman?

Portainer 2.15.1 running on top of up-to-date Fedora Workstation I am experiencing a network name issue.

It seems the name value is referencing the driver field value instead of the name field value.
"podman" != "bridge"

wrong name field is used here:

when I click on "bridge" network it shows proper name:

wrong name field is used here:

I am unable to create new containers because it errors out on the network name being invalid.

I had the same issue, but I was able to fix it by setting the cgroup manager to cgroupfs:
podman run -d -p 8000:8000 -p 9443:9443 --privileged --name portainer --cgroup-manager cgroupfs --restart=always -v /run/podman/podman.sock:/var/run/docker.sock:Z -v portainer_data:/data docker.io/portainer/portainer-ce:latest

I am unable to create new containers because it errors out on the network name being invalid.

I worked around this for now by creating a new bridge network named "bridge2". That one shows up with the correct name and appears to work fine.

Anyone has any insights about the issue with recreating containers?
I get an error 500 form the API with the message crun: cannot set memory swappiness with cgroupv2: OCI runtime error
Since I can start/stop/create/delete containers I don't fully understands what's the issue with recreating one...
Any more info or where to look or anything or an explanation why it cant be done/fixed?

A quick update to this old (but popular) thread: Portainer version 2.22.0 STS includes our first official support for Podman. Being our first release of this there may be some issues still, but for those of you with Podman enviroments that are willing to help us test and refine the feature, feedback on this release would be much appreciated.
