make-cloudflare

Cloudflare Pages direct upload for mkrun, in Python: publish a built directory with no Node on the machine and no wrangler in the pipeline.

# Makefile.py in a consuming repo
# /// script
# requires-python = ">=3.11"
# dependencies = ["mkrun>=0.4", "make-cloudflare>=0.1"]
# ///
from make_cloudflare import cloudflare  # importing is what registers the group

$ mk cloudflare.deploy site/dist --project mkrun     # production (branch main)
$ mk cloudflare.deploy site/dist --branch try        # a preview, on its own URL
$ mk cloudflare.projects                             # what the account has
$ mk cloudflare.deployments --limit 5                # one project's recent ones
$ mk -n cloudflare.deploy site/dist                  # the plan; nothing is sent

Credentials are the two variables wrangler already reads, so a repository that deploys from CI needs no new secret: CLOUDFLARE_ACCOUNT_ID and CLOUDFLARE_API_TOKEN (a token with Cloudflare Pages: Edit). The token's name ends in TOKEN, so mkrun treats it as a credential — it is withheld from the environment until a task asks for it, redacted in everything printed, and readable from the encrypted store. The project can come from --project or from CLOUDFLARE_PAGES_PROJECT in the repo's env layer.

Why this exists

wrangler pages deploy is four HTTPS calls and a hash. Reaching them through npx costs a Node toolchain in repositories that otherwise have none — a Rust one, a frontage one — and a node_modules in the deploy image of every one of them.

POST /accounts/<acct>/pages/projects/<p>/upload-token   -> a short-lived JWT
POST /pages/assets/check-missing                        -> what is not stored yet
POST /pages/assets/upload                               -> the files, batched
POST /pages/assets/upsert-hashes
POST /accounts/<acct>/pages/projects/<p>/deployments    -> the manifest

Three things make a naive port wrong, and all three fail silently — every call returns 200 and the site serves the old bytes, or none:

• The hash is BLAKE3 of a strange input: the base64 text of the contents with the extension (no dot) appended, first 32 hex characters. Not of the bytes, and not SHA-256. tests/test_pages.py locks it with a golden value.
• _headers, _redirects and _routes.json are not assets. They are fields on the deployment. Walk them in as ordinary files and the deploy reports success while the site's CSP stops applying.
• check-missing, upload and upsert-hashes take the JWT, not the account token, and carry no /accounts/<id> prefix — the JWT already names the account.

What it does not do

Pages Functions. A directory holding _worker.js or functions/ is refused by name rather than half-deployed: bundling a Worker is a build step, not an upload, and wrangler should keep doing it.

Steps 2 and 3 are undocumented. They exist because wrangler uses them, and Cloudflare can change them without a changelog; the documented deployments endpoint alone cannot upload a file. That is the real cost of dropping wrangler, and it is the reason this is a small module with a golden test rather than a wrapper nobody reads.

Nothing here is specific to any owner or account. The group name is cloudflare, and it merges with a repo's own cloudflare.* tasks — groups are namespaces — so only a same-named task collides; this package claims deploy, projects and deployments, nothing else. blake3 is the one dependency, and it lives here rather than in the runner so mkrun itself stays dependency-free.
