builds.sr.ht is our build automation platform. We're going to walk through the process of running jobs on builds.sr.ht and a look at few useful features.
Unlike platforms like Jenkins, builds.sr.ht does not allow you to pre-configure jobs. And unlike platforms like Travis, jobs are not inherently tied to a git repository. Each job on builds.sr.ht is described ad-hoc with a build manifest, which can be submitted to builds.sr.ht for processing.
Let's start with a basic manifest:
image: alpine/edge tasks: - example: | echo "hello world"
This is a build manifest, written in YAML. When we submit
this to builds.sr.ht, it will boot up an Alpine
Linux virtual machine using the edge release of
Alpine Linux. Then it will execute each of our build tasks - in this case,
Submitting jobs on the web
builds.sr.ht has a web submission form, where you can paste a build manifest and
submit the job without any additional configuration. This is a useful way of
testing build manifests before giving them a permanent home, or running one-off
tasks. Visit the job submission form and paste in
the example manifest. Add a note, perhaps
my first job, and click
run the job.
You'll be redirected to the job detail page. In a moment, one of our job runners
will pick up the task and start processing it. Within a few seconds, you should

Adding git repositories to builds
Let's try a new build manifest. This one is going to compile and test the scdoc project.
image: alpine/edge sources: - https://git.sr.ht/~sircmpwn/scdoc tasks: - build: | cd scdoc make - test: | cd scdoc make check
Before starting your tasks, builds.sr.ht will clone each repository listed in
sources to the build environment. You can have as many or as few (including
zero) git repositories as you like.
image: alpine/edge packages: - meson sources: - https://git.sr.ht/~emersion/mrsh tasks: - configure: | cd mrsh meson build - build: | cd mrsh ninja -C build - test: | cd mrsh ninja -C build test
This time, builds.sr.ht will install Alpine Linux's meson
starting your build. This uses Alpine's native
apk package manager - other
images use different package managers.
Testing on other platforms
Portability is important - so let's try running the same manifest on another operating system.
image: freebsd packages: - meson sources: - https://git.sr.ht/~emersion/mrsh tasks: - configure: | cd mrsh meson build - build: | cd mrsh ninja -C build - test: | cd mrsh ninja -C build test
This one happens to work without any changes, but note that some images have different names for packages, different distributions of coreutils, and so on.
Adding these builds to your git repository
If you put a build manifest in
.build.yml at the top of your repo, a build job
will be created each time you push new commits. You can also create multiple
manifests, for example to test multiple platforms, by putting several build
