How to schedule a one time run, non-repeating pipeline in AzurDevOps. I want to create this pipeline for our UAT environment, but I don't want to run it manually, so I was thinking is there a way I can put multiple specific dates to run the pipeline?
In short, we can't schedule a non-repeating pipeline in DevOps because it defines a schedule using cron syntax. Each Azure Pipelines scheduled trigger cron expression is a space-delimited expression with five entries(Minutes, Hours, Days, Months, Days of week).
If you need to run pipeline at some specific days, as a workaround, please schedule it on your end and call the Rest API to run your pipeline.
