--- title: Getting started with builds.sr.ht --- # Getting started with builds.sr.ht 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. ## Build manifests 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: ```yaml image: alpine/edge tasks: - example: | echo "hello world" ``` This is a build manifest, written in [YAML](http://yaml.org/). When we submit this to builds.sr.ht, it will boot up an [Alpine Linux](https://alpinelinux.org/) virtual machine using the edge release of Alpine Linux. Then it will execute each of our build tasks - in this case, saying "hello world". ## 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](https://builds.sr.ht/submit) and paste in the example manifest. Add a note, perhaps "my first job", and click "submit" to 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 see "hello world" shown under the "example" task. ## Adding git repositories to builds Let's try a new build manifest. This one is going to compile and test the [scdoc](https://git.sr.ht/~sircmpwn/scdoc) project. ```yaml 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. ## Adding dependencies scdoc is a simple project with no dependencies. Let's try a slightly more complex one: [mrsh](https://git.sr.ht/~emersion/mrsh), which depends on [meson](https://mesonbuild.com/). Here's a build manifest for it: ```yaml 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 package](https://pkgs.alpinelinux.org/package/edge/main/x86_64/meson) before 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. ```yaml 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 manifests at `.builds/*.yml`. ---
