builds.sr.ht docs

builds.sr.ht is a service on sr.ht that allows you to submit "build manifests" for us to work on. We spin up a virtual machine per your specifications and run your scripts in it. This is generally used to compile and test patches, deploy websites, build and publish packages, and so on.

How jobs are submitted

Unlike some other build systems, builds.sr.ht does not let you configure builds on the website itself. Instead, you write build manifests - YAML files that tell builds.sr.ht what to do. You can then submit these manifests via the API and we'll assign a runner and execute your job.

For convenience, there are ways of submitting builds automatically throughout the sr.ht ecosystem - for example by pushing to repositories on git.sr.ht. These integrations are discussed below. For details on submitting jobs via the API, see the API reference.

Build manifests

Build manifests are YAML files that contain a description of your build environment and steps to run in that environment. A very simple example could be:

image: alpine/edge
tasks:
- say-hello: |
   echo hello   
- say-world: |
   echo world   

When you submit this build, we'll fire up a virtual machine running an up-to-date image of Alpine Linux. Then, we'll copy your scripts into the machine and run them one at a time. More complex build jobs will probably use more features of the build.yml - here's an example that deploys web.synapse-bt.org:

image: archlinux
packages:
  - nodejs
  - npm
  - rsync
sources:
  - https://git.sr.ht/~sircmpwn/receptor
environment:
  deploy: synapse@synapse-bt.org
secrets:
  - 7ebab768-e5e4-4c9d-ba57-ec41a72c5665
tasks:
  - setup: |
      cd receptor
      npm install      
  - build: |
      cd receptor
      npm run build:production      
  - deploy: |
      cd receptor
      sshopts="ssh -o StrictHostKeyChecking=no"
      rsync --rsh="$sshopts" -rP index.html $deploy:/var/www/web.synapse-bt.org/
      rsync --rsh="$sshopts" -rP dist $deploy:/var/www/web.synapse-bt.org/

Build images

View the full list of supported build images.

Secrets

builds.sr.ht can keep track of secrets for you, like SSH keys or PGP keys, and include them in builds for the purpose of deployment. You can manage your secrets at the secrets dashboard. Each secret will only be included in the runtime image if the job was submitted using an OAuth key which has access to the secrets specified in the build manifest.

Build environment

Each task's script is given a preamble that looks like this:

#!/usr/bin/env bash
. ~/.buildenv
set -x
set -e

The actual shell varies depending on your build image. ~/.buildenv contains the environment variables you specified in your manifest, but feel free to modify it to communicate state between build steps.

Build status badges

If you add tags to your build, or enter search terms, you can use these to create a build status badge like this (the example being the latest status of builds.sr.ht itself):

builds.sr.ht status

The image URL and a markdown snippet are shown in the sidebar of the search results page or tag detail page.

Integrations

Do you have something that integrates with builds.sr.ht? Submit a patch for this page!

dispatch.sr.ht

dispatch.sr.ht offers a variety of integrations with builds.sr.ht, including support for connecting builds.sr.ht to external services like GitHub. This should be your first stop when looking for an integration.

git.sr.ht

git.sr.ht will automatically submit builds for you if you store a manifest in the repository as .build.yml. Each time you push, a build with this manifest will be submitted. If the repo you pushed to is present in the manifest's sources array, we'll edit it to point to the ref you just pushed. You can also submit several builds on each push by providing .builds/*.yml.

hg.sr.ht

hg.sr.ht will also automatically submit builds for you. The mechanism is identical to that of git.sr.ht as described above.
