Docker healthcheck uses hardcoded port instead of API_PORT

[luandro]

Description

The healthcheck in docker-compose.yml always calls localhost:3001:

healthcheck:
  test:
    [
      "CMD",
      "bun",
      "--silent",
      "-e",
      "fetch('http://localhost:3001/health').then(r => process.exit(r.ok ? 0 : 1))",
    ]

Deployments that set API_PORT to a different value will be marked unhealthy even when running correctly.

Impact

• Containers with non-default API_PORT will fail health checks
• Kubernetes/Docker orchestration may repeatedly restart healthy containers
• False negative health status in production deployments

Recommendation

Update the healthcheck to dynamically use the API_PORT environment variable:

healthcheck:
  test:
    [
      "CMD",
      "bun",
      "--silent",
      "-e",
      "fetch(\`http://localhost:\${process.env.API_PORT || 3001}/health\`).then(r => process.exit(r.ok ? 0 : 1))",
    ]

Priority

Medium - affects deployment reliability but only when using non-default ports
