Cancelling a Deploy a Release step: release deployed, but marked as cancelled

I have a project A with a Deploy a Release step which deploys a release from project B. I start a deployment in A and cancel it. The end result is that the Deploy a Release step is marked as cancelled, but actually project B is deployed.

Problems I can see with this:

1. The cancellation request doesn’t cause child deployment to be cancelled.

At the time when cancellation was requested (07:24:13), the child deployment was still not started, so it should have got cancelled.
Event if it was started, but still in package acquisition phase, the cancellation should be propagated from parent to child and the child deployment should be cancelled.

2. The status in parent project is incorrect

Task summary shows:


This clearly suggests that this step was cancelled. But Task Log shows:

Either the child task should really be cancelled (preferred), or at least the status in parent project should correctly show what really happened (that the child project was deployed).

Hi Jakub,

Thanks for getting in touch! I can certainly see the confusion with this behavior, both with the child project actually deploying when cancelling the parent, and the misleading text in the error message. This is actually “by design” currently, but we certainly agree that this behavior and/or error text should be improved on.

Cancelling the parent project shows the step as cancelled, but the child project’s task will run through to completion. There’s debate on if the child task should be cancelled here (I’m leaning this way myself), but we should at least update the wording here. After a long discussion with my team, these changes will be harder to implement than it first appeared. The following enhancement issue will be used for updating this behavior, and you can track its progress at the following link.

If you’re wanting to cancel the child task, the only workaround is to go into the child task and cancel it directly (which you can follow with the View deployment link in the log). If you have many deploy a release steps, this should still only have to be done once each time, as cancelling the task will prevent the next from starting.

My apologies that this has caused confusion here. Please don’t hesitate to reach out if you have any questions or concerns moving forward. :slight_smile:

Best regards,

Thanks for the reply, @Kenneth_Bates.
I’ll track the GitHub issue.

Regarding your comment that “If you have many deploy a release steps, this should still only have to be done once each time, as cancelling the task will prevent the next from starting.” - it is true only for sequential deployment steps. In our case, we have up to ~70 parallel Deploy a Release steps in various projects, so the problem we face is that we cancel the master project, but still all those 70 projects continue deploying. We’d need to cancel each of them individually, which I’m sure you understand is an extremely tedious and unreliable way to cancel a broken production deployment.

Hi Jakub,

That is a great (and unfortunate) point, and I didn’t think about that. That certainly sounds extremely tedious. Would something like a manual intervention step in your parent project immediately before the Deploy a Release steps in order to pause the deployment which you could cancel at that point help out at all here? You could scope this step to run only in production as well.

I hope that helps. Let me know what you think or if you have any further questions. :slight_smile:

Best regards,


Thanks for the suggestion, but a manual intervention step wouldn’t really help here - it would help only if I wanted to cancel the deployment immediately after starting it (before any “real” deployments - the parallel Deploy a Release steps - are started), while what I want is to be able to cancel an ongoing deployment (i.e. when the parallel phase has already started). For example, when one of the Deploy a Release steps completes and we immediately discover that it has broken the environment, we want to cancel the rest of the deployment to be able to roll back quickly - currently this is impossible, because all the remaining ~70 projects continue deploying unless stopped manually one by one.

Hi Jakub,

Thanks for following up, and I can see exactly what you mean here. After a good long think about this, I’m not sure how close to the ideal solution we can get. I think the closest would be to have a custom script to grab all of these separate child deployments to cancel, which you could then manually trigger right after you click the Cancel button on the parent project. The following is a sample script on cancelling a deployment which might help get you started if this sounds like it would help.

I was trying to find a way to be able to trigger this script to be run based on the cancellation, but I don’t think that’d be possible out of the box. A possible future option would be to subscribe to an event and trigger a script like this based on that event. The following UserVoice suggestion might be worth throwing some votes to. :slight_smile:

I’m sorry it’s not better news! Let me know what you think or if you have any other questions going forward. :slight_smile:

Best regards,


Thanks for the tip. My team will discuss whether we want to invest in building a cancellation automation. Can you share what the decision regarding is going to be - will the child deployments cancel, or will only the log message be corrected? We really hope cancellation of child steps will be supported out of the box.

As for UserVoice - all of my votes are on way more important items, mostly related to improvements related to variables. Unfortunately your team ignores them for years already (the oldest one is from February 2014).
