Have you ever found yourself staring at a failed CI build, wondering desperately what happened? Or, have you ever needed a fresh machine on-demand to test out an idea in? Have you been working on Linux, but need to test something on OpenBSD? Starting this week, builds.sr.ht can help with all of these problems, because you can now SSH into the build environment.
The next time your build fails on builds.sr.ht, you’ll probably notice the following message:
After the build fails, we process everything normally - sending emails, webhooks, and so on - but keep the VM booted for an additional 10 minutes. If you do log in during this window, we keep the VM alive until you log out or until your normal build time limit has elapsed. Once you’ve logged in, you get a shell and can do anything you like, such as examining the build artifacts or tweaking the source and trying again.
$ ssh -t email@example.com connect 81809 Connected to build job #81809 (failed): https://builds.sr.ht/jobs/~sircmpwn/81809 Your VM will be terminated 4 hours from now, or when you log out. bash-5.0 $
You can also connect to any build over SSH by adding
shell: true to your build
manifest. When you do, the VM will be kept alive after all of the tasks have
finished (even if it doesn’t fail) so you can SSH in. You can also SSH in before
the tasks have finished, and tail the output of the build in your terminal. An
example use case might be getting a fresh Alpine environment to test build your
This was accomplished with a simple build manifest:
image: alpine/edge shell: true sources: - https://git.alpinelinux.org/aports tasks: - "prep-abuild": | abuild-keygen -an
Since build manifests run normally in advance of your shell login, you can do things like install your preferred editor and dotfiles, pull down your SSH keys through build secrets, or anything else you desire to set up a comfortable working environment.
Furthermore, by leveraging the builds.sr.ht API, you can write scripts which take advantage of the shell features. Need a NetBSD shell? With a little scripting you can get something like this working:
With experimental multiarch support being rolled out, soon you’ll be just a few keystrokes away from an ARM or PowerPC shell, too.
I want to expand more on SSH access in the future. Stay tuned and let me know if you have any cool ideas!
