Get podname's of each stage in workflow

[kollurukailash]

A workflow has step1 -> step2 -> step3. When triggered, How to get pod names at each step1, step2, step3.?

Purpose:
Currently, all my logs of workflow were saved as artifact in s3. And to get them through rest API
/artifacts/{namespace}/{name}/{podName}/{artifactName}.
need the pod name.

See pod.name: https://github.com/argoproj/argo-workflows/blob/master/docs/variables.md#containerscript-templates

If you are using v1 pod names, they are the same as the node ID in node statuses. You can get the node statuses from the workflow spec (via GET call).

So, we scrape from /api/v1/workflows/{namespace}/{workflow_name} right ?

yes

How should I obtain the pod name when the pod-name version is v2 ?

[BrunoGrandePhD]

@wanlxp Given that the GET endpoint doesn't return the pod name when using pod names v2, I got around this by creating an output parameter that captures the pod name (see below). This way, the pod name gets included in the GET response.

outputs:
  parameters:
    - name: pod-name
      value: "{{pod.name}}"

Posting here because its related and this came up when I was searching: The above is correct for getting the pod name, but the container name will be main !
