Action Checklist
- Verify Dockerfile compatibility with Sandbox resource limits Ensure the image does not exceed allocated memory or CPU quotas
- Update deployment configuration to reference the container image Check vercel.json or dashboard settings for new container options
- Validate environment variables and secrets mapping Confirm that existing secrets are correctly injected into the container
- Test networking and port binding in the staging environment The sandbox may have specific restrictions on outbound traffic or listening ports
- Monitor logs for initialization errors during the gradual rollout Use Vercel Observability to track startup performance and failures
