Remove PipelineTask Timeout in Favor of TaskRunSpecs

[danielhelfand]

As of #2389, PipelineRuns now support the ability to define runtime settings of TaskRuns associated with a PipelineTask.

Prior to this, #2038 was introduced as a way to specify a timeout for a PipelineTask. Seeing as it seems the design moving forward will be to define these runtime settings all via PipelineRuns/TaskRuns, would it make sense to remove the Timeout property from PipelineTasks?

If we want to do this id kind of like to revisit all the PipelineTask fields and make sure we are happy with them. A while ago I tried to categorize them:

Used to instantiate the TaskRun:

• taskref
• taskspec
• resources
• workspaces
• timeout
• params

Used to decide when and how to run (i.e. workflow logic):

• conditions/when
• retries
• runafter

These are modified at runtime via PipelineTaskRunSpecs:

• ServiceaccountName
• PodTemplate

The specific fields you mentioned, one is at Pipeline authoring time, one is at PipelineRun time - if we remove timeout from PipelineTasks, this means Pipeline authors can't set it - which might be frustrating?

I think there are questions around:

• Which make sense to ONLY set at runtime?
• Which make sense to OVERRIDE at runtime but also allow at Pipeline authoring time?
