Expected Behavior

Pipelines with tasks that have retries set should rerun a taskRun where it fails.

Actual Behavior

It does not rerun

Steps to Reproduce the Problem

  1. Run the below pipeline run,
  2. watch the resources which complete too quickly to have run the 30 second sleep

Additional Info

Below are the sample resources, a watch of the task run and the taskRun after its completed.

Note the tasks complete too quickly to have actually executed and the retried status entries are all duplicates. On previous versions I'm seeing this work as expected with a different pod per task retry. I'm not seeing any issue or pr to explicitly change this behaviour around a pod per retry which implies it might be accidental.

@vdemeester FYI
0f20c35#diff-14481606a469dcd50f6cb9f5540e3b06R543 and 0f20c35#diff-14481606a469dcd50f6cb9f5540e3b06L322

Looks like its the same issue I described in slack, the assumption of a 1:1 mapping between a taskRun and a pod. The retry pod will never be created. Not sure how to fix given we have the same issue around not being able to uniquely identify a pod which failed/is retrying or has retried, could do a count for the pods but then once completed we wont know which status to attach to the task run

Something is weird though, I thought the retries in pipeline would generate new TaskRuns instead of re-using the same… It is interesting that it does not 😅

Reusing the same TaskRun is weird, as this means we are doing the following:

  1. Create TaskRun
  2. TaskRun Fails
  3. Update the TaskRun status to force the reconciler re-running it

This.. well… doesn't work well as of now as the pod being already there… it fails instantly (where it would re-create it before for some odd reason – well not so odd podName gets removed)

  • The way retries are implemented make the assumption that a TaskRun can spin multiple Pod (depending on what we do). In a gist, if a TaskRun fails but had a number of retries in the Pipeline, it clear the status (removing lots of things, and podName) and makes the assumption that the TaskRun reconciler will re-create a Pod.
  • The way TaskRun works (as of 0.10.1) makes a TaskRun able to have only 1 Pod and will not re-create one, ever (except if you delete the Pod and clear the status)

This puts this fix in a weird state (and it makes it a huge fix to do as far as I can see)

  1. Either we make the assumption that there is a 1-1 relation between TaskRun and Pod, and then we need to rewrite how retries work. We can add a little something in the TaskRun to make it know how much it should retry (more or less moving the retries feature to the TaskRun reconciler), and letting it handle that or we create a TaskRun for each retry (and let the feature on the PipelineRun reconciler).
  2. Or, on retries, we delete the Pod, clear the status and let the TaskRun reconciler do its things — this is the worse, as we litteraly are removing Pod (and thus logs of the failure), I can't see a good reason to do that

Clearing the status and deleting the pod does not sound like something we want to do. at least not until we have a way of storing status and log somewhere else.

If I understood correctly the change that broke things is the fact that the reconciler does not rely for podName from the taskRun anymore. My suggestion would be to revert that change for now to fix this. We can then take time in 0.11 to design a new way for retries to work together with #1709.
