Add a Post-Merge Hook to Repository

Hello,

I would like to be able to add a post-merge like hook that would ssh into a production web server and pull changes from a repository that has had a pull request merged into it. I've read all the other posts on this and I see that a webhook is the most recommended method. However I am not comfortable with publishing a page that executes code on my public-facing server. Is there another way to use a webhook that I'm unaware of that would prevent potential unauthorized code execution on my public-facing server?

I am quite surprised that this isn't a feature that has been made more accessible (i.e. without having to write my own add-on) to paying customers. It seems like this should be a standard part of the hooks available to Stash.

Anyway, any insight would be greatly appreciated.

-Tim.

Hi Tim,

Stash Pull Requests use 'git merge' command for sure.

Kind regards,

You should write a plugin that has a listener to PullRequestMergedEvent and does the SSH/deployment you need in the event handler.

As I alluded to in my original post, I was hoping to avoid having to learn Java, learn the Atlassian libraries, and then write my own plugin. I just don't have the time at the moment.

As a workaround, I was able to get a webhook add-on to do what I needed by locking down a specific port on my webserver to only allow traffic from my development server's ip address.

But like I said, this sort of functionality seems like it should just be part of the out-of-box functionality.

Hi Tim,

Maybe you don't need to write a plugin, but configure a Git post-merge hook?

If this answer was helpful, please allow me to ask you to mark my answer as accepted in order to have it in the top of the thread, also helping other customers.

Thanks in advance!

That's not a bad idea. I had the same thought, but I wasn't sure I could do that without interfering with Stash's operations. Also, I've read elsewhere that a merge from a Stash Pull Request doesn't actually use the 'merge' command. Can you shed a little more light on this?

 

Thanks!

Interesting, I'll have to play around with this. Thanks for your insight!
