Podman Machine VM config does not get created when an Ignition file is provided #23544

cheesesashimi · 2024-08-07T23:03:50Z

Issue Description

Whenever the --ignition-path argument is provided to podman machine init, Podman silently fails to write the <machine-name>.json config file. If I add the --now flag or when I try to run podman machine start <machine-name>, I get the following error:

$ podman machine init --ignition-path=./ignition.json

$ rpm -q podman                     
podman-5.1.2-1.fc40.x86_64

Steps to reproduce the issue

Create a new Podman machine VM by running the following command: podman machine init --ignition-path=./ignition.json.
Try to start the newly created VM by running podman machine start.

Describe the results you received

Whenever I run podman machine init --ignition-path=./ignition.json, it fails to create the podman-machine-default.json and podman-machine-default.ign files. Running this with --log-level=debug below provides the following output:

$ podman machine init --log-level=debug --ignition-path=./ignition.json

By comparison, omitting the --ignition-path flag yields the following normal behaviors:

Describe the results you expected

I would have expected the podman-machine-default.json file to be created and the VM should be able to start by running podman machine start <vm-name>.

Podman in a container

Additional environment details

Additional information

This only occurs whenever the --ignition-path= option is provided to podman machine init. Otherwise, it works as it should. I did a bit of debugging and code spelunking to try to figure out how / why this is happening, and found this:

https://github.com/containers/podman/blob/main/pkg/machine/shim/host.go#L193-L198

So essentially, we return early and never make it to this part:

https://github.com/containers/podman/blob/main/pkg/machine/shim/host.go#L237-L247

I feel like I have enough context that I can submit a PR to fix this issue. However, what I'm not sure of is what the preferred behavior should be whenever a user provides their own Ignition config. In other words, should the ready.service unit be added to the user-provided Ignition config or should the user-provided Ignition config be used as-is:

https://github.com/containers/podman/blob/main/pkg/machine/shim/host.go#L200-L220

Personally, I'm of the opinion that the ready.service unit should not be added to user-supplied Ignition, but I could be persuaded otherwise. Anyway, please let me know if there is any further information that would be helpful here.

I would welcome a PR and nice find! The behavior is like so. If the user provides an ignition file, we do no additional ignition changes (so no ready unit). And yes, we should be writing a JSON and we should write a regression test as such with your PR (just init and check the json is there, we dont have to start it). lmk if you need any help with this one.

I am running into this bug as well. Is there a work-around that can be used in the meantime?

gaufde · 2024-10-03T06:20:28Z

@baude I've been trying to figure out a work-around for this issue by either modifying the default ignition file and replacing it with my own, or creating the missing JSON file.

When I try the above methods and then try podman machine start the process just hangs and it never actually starts. However, I just realized, that the reason it hasn't appeared to work is probably because of the ready.service unit. Right now I see it only mentioned that the user needs to handle this themselves.

--ignition-path

Fully qualified path of the ignition file.

If an ignition file is provided, the file is copied into the user’s CONF_DIR and renamed. Additionally, no SSH keys are generated, nor are any system connections made. It is assumed that the user does these things manually or handled otherwise.

Is there documentation somewhere for me to learn how to do this manually or add the necessary units to my butane file?

Also, is that right that an ignition file that has been tested to work on FCOS running elsewhere (e.g on a VPS) would have problems starting using podman machine start (assuming this issue about the JSON file is fixed)?

What is the progress of this ? Do we know what constitute service.ready yet - Also can someone maybe point me to more reading material on it - I also would like a workaround - I mean for those that don't included SSH authorize public keys and users and potentially only specify other things in their ignition file, it would have been nice to be able to have a working podman machine afterwards.

Any details regarding that service.ready unit will help!
