chant on Fly and containers

For a team that runs on Fly Machines and containers: Apps and Machines applied straight to the Machines API, Sprites for sandboxes, and Docker files from the same TypeScript.

Works

• Fly Apps and Machines applied straight to the Machines API by flyApply, with no flyctl and no state file
• The whole deploy offline against the mudflaps emulator first, then against real Fly by dropping one override
• Sprites as disposable build sandboxes and agent workers, rewound to a checkpoint when a step fails
• Docker Compose services and multi-stage Dockerfiles from TypeScript

Differs

By forge

GitHub

• --generate github writes the pull-request workflow under .github/workflows/, run on pull_request and on push to the target branch.
• Both jobs use the job's own github.token. On a pull request from a fork that token is read-only, so the plan note and the status are not posted.

GitLab

• --generate gitlab writes .gitlab-ci.yml, and apply runs one at a time per environment through resource_group.
• A CI job token cannot write merge request notes, so set a project access token with the api scope as the masked variable CHANT_FORGE_TOKEN.

Forgejo

• --generate forgejo writes the GitHub workflow in the Forgejo dialect under .forgejo/workflows/: the runner label, action references by URL, and no permissions block.
• Forgejo workflows are GitHub-dialect, so chant audit applies its GitHub rules to them.

First step

npm install --save-dev @intentius/chant-lexicon-fly
npx chant init my-app --lexicon fly

Or hand this step to your coding agentIt stops at a pull request or a report.

Read https://intentius.io/chant/for/fly/.
Set up chant with the fly lexicon in this repository.
Install it with `npm install --save-dev @intentius/chant-lexicon-fly`, run `npx chant init . --lexicon fly`, and read every `skills/*/SKILL.md` it writes before you author anything.
Run `npx chant build` and `npx chant lint` until both pass, and open a pull request with the result. Deploy only to the mudflaps emulator, and only when I ask.
Never deploy to a real cloud account or shared environment (with `chant run`, `chant components` or a platform's own CLI), approve (a pull request review, `chant approve` or `chant run approve`), override a policy denial (`chant approve policy-override`), or merge; never cut or publish a release (`chant release cut --yes` or `chant release publish`), push or delete a `ci/*` tag (`chant ci tick` pushes them), or change the value of an existing flag; never touch `.chant/allowed_signers` or `chant/lifecycle`.
