Rebuilderd is an independent verification system for binary packages. It allows verification of pre-compiled packages by repeating the build step in an identical environment and then verifies that the package is identical. Right now only Arch Linux packages can be verified.
If you run a rebuilder or consider running a rebuilder feel free to join the #archlinux-reproducible IRC channel.
On a single machine you just enable
rebuilderd.service and the worker service(s):
Afterwards you can verify rebuilderd is correctly running with a single worker by running:
# rebuildctl status
If you get an error that no authentication cookie could be found, you might need to add yourself to the
rebuilderd user group.
Continue with the next section to sync packages that our worker can rebuild.
To securely run a rebuilder network we need to configure a secret key for administration with rebuildctl, and another secret key that is used by our workers to sign up. The secrets can be generated with
pwgen -1s 32.
[http] # it is highly recommended to bind to localhost and setup nginx as a reverse proxy for https bind_addr = "127.0.0.1:8080" [auth] # set the generated secret for administration here cookie = "INSECURE-CHANGE-ME" [worker] # set the generated secret for our workers here signup_secret = "INSECURE-CHANGE-ME"
Next we head over to our worker machines to set them up. Install
## The rebuilderd to connect to endpoint = "https://rebuilder.example.com" # change this to the generated secret for our workers signup_secret = "INSECURE-CHANGE-ME"
Syncing packages to rebuild
The rebuilder setup will not do anything by default until you explicitly configure where to sync packages from. The sync profiles are configured in
/etc/rebuilderd-sync.conf. The profile names are supposed to be unique. You configure it to only build packages of a specific maintainer with the
maintainer option. By default it is importing packages of all maintainers.
## rebuild all of core [profile."archlinux-core"] distro = "archlinux" suite = "core" architecture = "x86_64" source = "https://ftp.halifax.rwth-aachen.de/archlinux/$repo/os/$arch" ## rebuild community packages of specific maintainers, or whitelist packages by name. ## If no filter is set, all packages are imported, if both filters are set the package only ## has to match one of them to be included. #[profile."archlinux-community"] #distro = "archlinux" #suite = "community" #architecture = "x86_64" #source = "https://ftp.halifax.rwth-aachen.de/archlinux/$repo/os/$arch" #maintainers = ["somebody"] #pkgs = ["some-pkg", "python-*"] #excludes = ["tensorflow*"]
Afterwards you can enable
email@example.com to automatically sync the profile.
An Ansible playbook with a rebuilderd role can be found in Arch Linux's infastructure repository. Use this as inspiration as the Ansible repository is heavily dependent on how the Arch Linux infrastructure is set up.
Tips and tricks
Requeueing failed builds
There is currently no builtin way to requeue, you can run the following command to add all failed builds to the queue again:
# rebuildctl pkgs ls --distro archlinux --suite core --status BAD --json | jq -r '..name' | xargs -L1 rebuildctl queue push archlinux core
Failed to allocate scope: Unit build.scope already exists
This is happening if multiple versions of repro are running at the same time. This is going to be fixed in a future version.
