Git artifacts detached from revision

[wsams]

Pre-requisites

• I have double-checked my configuration
• I can confirm the issues exists when I tested with :latest
• I'd like to contribute the fix myself (see contributing guide) (I would fix myself but I am not allowed at my organization. I may only report during business hours.)

What happened/what you expected to happen?

When using a standard git input artifact in Argo Workflows v3.4.3 or latest to clone a repository, the resulting source directory will not be on the branch that was cloned.

If you were to exec into the container that ran a git clone and run git branch you will see (based on the workflow I provided),

* (no branch)
  main
  feature/2022q4

We recently upgraded from v3.2.7 where the clone would have been on the branch feature/2022q4 based on the sample workflow I've provided.

Version

v3.4.3

Paste a small workflow that reproduces the issue. We must be able to run the workflow; don't enter a workflows that uses private images.

apiVersion: argoproj.io/v1alpha1
kind: Workflow

  generateName: test-git-clone-

  templates:

            path: /clone

              repo: https://github.com/wsams/latex

Logs from the workflow controller

I ran,

kubectl logs -n argo-ns deploy/workflow-controller | grep ${workflow}

but as far as I can tell nothing related to this git clone was logged.

Logs from in your workflow's wait container

I ran the following because this workflow completes successfully. There are no errors in any of these steps.

We changed the Git library in v3.4. That is probably the cause, but a revert isn’t going to happen anytime soon.

I think there might be a workaround. Have you tried branch: instead?

[alexec]

Also, please make sure you don’t have both a label and branch with the same name. Git does allow that.

Hi @alexec , thanks for the update. I'll give branch a try. It looks like we have to switch to singleBranch mode, but I think that will be okay - we're only interested in one of the branches. I do have a workaround in place, but if branch works that would be cleaner. Here's what I have at the moment. I added a revision input parameter that will set the revision on the git artifact. And then in the script body I checked it out. These workarounds should be fine for now.
