/kind bug

Description

When creating networks via docker compose, functionality which worked via virtualbox no longer works with podman machine.

Steps to reproduce the issue:

Create a docker-compose.yml:

services:
  testservice:
    image: docker.io/alpine:latest
    volumes:
      - "testvol:/testvol"
    networks:
      - "testservice-net"

networks:
  testservice-net:

volumes:
  testvol:

Run docker-compose up

Describe the results you received:

For what it's worth, I got docker-compose working here using largely the approach suggested by #11397 (comment).

Same problem here in MacOS.
Even when I logged in Podman VM, created a custome network in rootfull mode, and run podman run with the created custom network, the same problem happened.

Can you paste the output of the file. It looks like it does not contain proper json.

linhmtran168 · 2021-09-03T09:34:15Z

@Luap99 This is the content of created /etc/cni/net.d/podmantest.conflist file. I think it's a valid json.

Luap99 · 2021-09-03T09:41:41Z

Yeah the network file looks good. It looks like one of the cni plugins is failing. Can you run the process with strace -f this should show where it fails.

linhmtran168 · 2021-09-03T10:07:54Z

@Luap99 Since the VM created by podman machine is running Fedora CoreOS, it doesn't include strace. I tried to use toolbox to install strace, but in the toolbox, podman command failed to run. I'm new to podman and CoreOS as well, so could you tell me how to use strace to debug podman inside CoreOS VM?

Luap99 · 2021-09-03T10:13:12Z

Ah, I am not a coreos user so I don't know what the best way to install strace or such tools.
Maybe a easier option is to remove the podman-machine plugin part from the config file. I think plugin might cause troubles.

linhmtran168 · 2021-09-03T11:17:52Z

@Luap99 Thank you. It's just as you said removing the podman-machine part make the podman run command succeeded. It even works with rootless network. But now the forward port mapping to MacOS host is not working anymore.

In the MacOS host, if I don't use custom network, forward port mapping is working fine.

$ podman run --rm -it --name nginx -p 8888:80 nginx

But with custom network, the port is not forwarded (it works fine inside the podman VM though)

podman run --network podmanmacos1 --rm -it --name nginx -p 8888:80 nginx

Luap99 · 2021-09-03T11:21:13Z

Yes the podman-machine plugin sets up the port forwarding, so there is a bug with the plugin. I will see if I can find it.

jpapejr · 2021-09-03T11:59:55Z

I’ve been seeing this “unexpected end of JSON input” error all day yesterday while playing with the latest podman for Mac (after the docker announcement) and I’ve seen it with some rather simple used cases to. I’ll do some testing and report back the images and use cases that fail. Part of the problem is that even with log-level=trace I don’t get any more detail on why the failure happens than the base CLI output.

However, just adding the -P to publish the ports results in a working container

Happens in the same manner whether rootless or rootful connection.

When no ports are set we still have to return the CNI result back. Otherwise CNI will fail with `unexpected end of JSON input`. Fixes containers/podman#11413 Signed-off-by: Paul Holzinger <[email protected]>

Luap99 · 2021-09-03T13:16:41Z

TLDR, the bug is that you cannot use the machine plugin without ports.
PR containers/podman-machine-cni#3 to fix this.
