A FAILED pipeline execution stuck in "PREPARING WORKSPACE" state is blocking further execution of the pipeline.
This can cause future executions of this pipeline to remain in QUEUED status and not execute.
Environment
Aria Automation Pipelines / Code Stream 8.x
Cause
In the Kubernetes workspace in CI task, the pod can get created & CI agent link available, without the task progressing from WORKSPACE_CREATION to 'RUNNING'.
Resolution
In order to delete a stuck execution, its possible to reveal the Delete action via a keyboard combination:
Option + Shift + D on Mac.
On Windows or Linux, the combination is: Alt + Shift + D.
This has to be done on Executions page of Aria Pipelines, and it toggles the appearance of "Delete" in this menu
Alternative, workaround:
If executions are limited by the concurrency value, no further executions get scheduled until this is increased.
