Installation¶

Most people never install touchmark by hand: they create a hub from the template, and the hub's CI runs it. Install it on your machine to try a pack on a checkout, to run setup once, or to plan from a laptop.

Every release has archives for Linux, macOS and Windows on amd64 and arm64, and the image for linux/amd64 and linux/arm64. All of them carry the same binary, and the version is the same everywhere: the tag vX.Y.Z, the image tags X.Y.Z, X.Y and latest, and touchmark version.

Pin a version, and let Dependabot (the Action) or Renovate (the image) propose the next one in a pull request you review.

From an archive¶

v=X.Y.Z
base=https://github.com/bedrock-python/touchmark/releases/download/v$v
curl -fsSLO "$base/touchmark_${v}_linux_amd64.tar.gz"
curl -fsSLO "$base/checksums.txt"
sha256sum --check --ignore-missing checksums.txt
gh attestation verify "touchmark_${v}_linux_amd64.tar.gz" --repo bedrock-python/touchmark
tar -xzf "touchmark_${v}_linux_amd64.tar.gz" touchmark
./touchmark version

gh attestation verify checks the archive's build provenance: that GitHub Actions built it in bedrock-python/touchmark. Releases has the stricter checks, down to the workflow that signed.

On Windows, take touchmark_X.Y.Z_windows_amd64.zip and put touchmark.exe on your PATH. On macOS, darwin_arm64 or darwin_amd64.

With Go¶

go install github.com/bedrock-python/touchmark/cmd/touchmark@latest

Go 1.26 or newer. A binary built this way reports the module version in touchmark version.

The image¶

ghcr.io/bedrock-python/touchmark holds touchmark and git (2.45 or newer, no git-lfs) on Alpine, and runs as the non-root user touchmark (uid 65532). Its entrypoint is touchmark. It has a shell because the CIs that run it need one (GitLab's Docker executor runs the job script with sh), but touchmark never starts a shell: it runs git with an argument list. Its system git config trusts every directory (safe.directory), so a hub checkout that belongs to another user, as in most CI jobs, can be read.

docker run --rm ghcr.io/bedrock-python/touchmark:X.Y.Z version

On your machine, in a checkout of a target, with the hub next to it; --user lets apply write files you own:

docker run --rm --user "$(id -u):$(id -g)" -v "$PWD:/work" -v "$HOME/src/engineering-assets:/hub:ro" -w /work \
  ghcr.io/bedrock-python/touchmark:X.Y.Z status --hub /hub --repo acme/billing

Requirements¶

• git 2.31 or newer for check, status, apply and manifest; git 2.45 or newer for plan and distribute, which read every target into a repository of their own with lazy fetches off, check-attr --source and --attr-source. An offline plan (a hub pull request without read credentials) reads no target and runs on 2.31. The image brings its own git.
• A full clone of the hub. touchmark reads the hub's whole history and refuses a shallow or partial clone.
• Network access to the platforms in hub.yml, for plan, distribute, doctor, setup and migrate. check, status, apply and manifest work offline.

Next: create a hub on GitHub, on GitLab or on Gitea or Forgejo.
