Expected Behavior

Expected task to run, fail, or be refused as invalid when added originally

While writing this report it finally failed

Some detail as to why this happened and maybe where to look to debug this would be great. I tried looking for the pod, describing the pipelinerun, I had a little look at the tekton-pipeline-controler’s logs but gave up quite quick as they’re pretty hard to read in the terminal

Actual Behavior

Pipeline sat with an incomplete pending task, no pod for the task, pipeline run also doesn’t show a pod for ages

Steps to Reproduce the Problem

1. Create KIND cluster
2. Deploy operator (I was using 0.22.0-1)
3. Deploy config all
4. Apply task below + tkn hub install -> tkn hub install task git-clone golang-build golang-test
5. Apply pipeline below (modify FILLTHISIN parts)
6. Apply PVC below
7. Run pipeline using tkn
