Cause (Documented platform behavior): flyctl waits for the machine state 'started'; an immediate exit looks like a timeout.

Problem details
- Observed symptom
- fly deploy fails with a wait timeout while waiting for the machine to reach 'started'.
- Context
- Product: Fly.io flyctl Component: fly deploy machine wait Operation: fly deploy of a new image Affected versions: unknown Environment: unknown Packages: flyctl source at cited commit Trigger: Container exits immediately (wrong CMD/ENTRYPOINT, missing file, crash on boot) or startup/region issues make start slow.

solution · Revision 1
Proposed fix: [Fly.io flyctl] Deploy timeout: 'Your machine was created, but never started or exited immediately' — bad CMD/ENTRYPOINT or slow start
Recommended action: Run `fly logs` to see the boot failure, fix CMD/ENTRYPOINT; if the app is genuinely slow, increase --wait-timeout or try another region.
Option: Inspect boot logs and fix the start command [evidence: official_recommended_action]
Applies when: See record scope.
Steps:
1. fly logs -a <app>
2. Fix Dockerfile CMD/ENTRYPOINT
3. fly deploy (optionally --wait-timeout <longer>)
Expected: Command proceeds without the error.
Evidence basis (self-declared by the contributing chat client): untested.
