GitHub Actions: Concurrency

Using the "concurrency" keyword, you can better control your GitHub Action workflows to ensure they run how you want them to run. For example, you want to make sure you are only have one workflow deploying to production at any specific time.
This video will walk you through getting started with the "concurrency" keyword in GitHub Actions

Ur a godsend was doing research on how to implement this for a company's project. Thanks so much!

[@MickeyGousset]

Glad it was helpful!

The best video channel on GitHub workflow with proper hands on example

Thank you so much!

[@DevaMARICHAMY]

Clear and crisp explanation! Thank you so much!

[@bulelanibotman]

thank you so much! i absolutely love your calm voice, i understand stuff very nicely

[@FoysalAhmedfashuvo]

Thanks for the detailed video. It helped me to better understand the concept :)

I want to prevent 2 different workflows from running at the same time, but its still important for me that all workflows are being run, so i cant have pending workflows getting cancelled, just because a new one is added to the queue. Is there anyway around this?

[@morganl9601]

Found any solution ? I'm in the exact same situation.

[@MrBa143]

@@morganl9601 Wasnt possible to my knowledge

[@mymawazo1449]

use the "needs" keyword i.e job1 "needs" job2. You can then add if: always or if: success

[@MrBa143]

@@mymawazo1449 Wouldnt that be 2 jobs in 1 workflow? Not 2 different workflows

[@mymawazo1449]

@@MrBa143 Ah your right, I misunderstood your question. From what I can gather, a hack would be, to use a repository_dispatch custom event from one workflow which you can then listen for in another workflow. I've not tried this but it might work,

Thanks a lot

[@grzegorzbajson3897]

Thanks for this video. Would you have any idea how to implement this concurrency between different repos within one Organisation?

[@MickeyGousset]

Oooohhh that is an interesting idea but it won’t work out of the box I don’t think, because it’s based off the same workflow being started.
What’s your scenario with this?

[@grzegorzbajson3897]

@@MickeyGousset Many multiservices from different repo tested in one k8s cluster. So far I implemented my own locking mechanism that uses org variable, but it's not reliable, because there is no atomic operation for reading-and-writing var value.

[@MickeyGousset]

@@grzegorzbajson3897 ah so you want to make sure that if one repo is deploying that a second repo waits till the first is done? Let me think on that

[@grzegorzbajson3897]

@@MickeyGousset Yes, that's right. Thanks!

[@SohailKhan-ll9kh]

Hey Mickey. Where can I find this particular file in the repositories?

[@MickeyGousset]

If you’re referring to the workflow file, it should be in the .github folder, and then in a folder called workflows.

[@SohailKhan-ll9kh]

Great. Do you know which repo its in?

[@janjoosse3325]

Nice video!
