The publish workflow was pushing platform/Dockerfile (Go-only) to the Fly registry, but tenant machines run the combined image (Go + Canvas reverse proxy). This caused "canvas unavailable" after machine update. Changes: - Fly registry build: platform/Dockerfile → platform/Dockerfile.tenant - GHCR: keeps Go-only image (for self-hosted/dev use) - Path triggers: add canvas/** and manifest.json (tenant image includes both) Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

|
|
# `docker login` on macOS unconditionally writes credentials to the
|
|
# osxkeychain credential helper, even when DOCKER_CONFIG/config.json
|
|
# declares `credsStore: ""` and even when invoked with `--config`.
|
|
# Verified locally 2026-04-16 — after a successful login, Docker
|
|
# rewrites the same config file to:
|
|
# { "auths": { "ghcr.io": {} }, "credsStore": "osxkeychain" }
|
|
# i.e. the auth lives in the Keychain, not the config file. The
|
|
# Mac mini runner is a launchd user agent with a locked Keychain,
|
|
# so storage fails with `User interaction is not allowed (-25308)`.
|
|
#
|
|
# Six prior PRs (#273, #319, #322, #341, #484, #486) all kept calling
|
|
# `docker login` and tried to coerce credsStore — none worked.
|
|
# The only reliable fix is to skip `docker login` entirely and write
|
|
# the auth strings directly. `docker/build-push-action@v5` and the
|
|
# daemon honor the `auths` map for push without needing login.
|
|
#
|
|
# Fly registry username MUST be literal "x" (verified 2026-04-15) —
|
|
# any other value returns 401. FLY_API_TOKEN lives in GitHub Actions

# secrets AND in `fly secrets` on molecule-cp; see
|

# docs/runbooks/saas-secrets.md before rotating.
