Security and requirements

Level: Standard. What this template needs:
  • Nothing beyond a standard container: no extra privileges, host mounts or published ports.
What Levelrail adds around it:
  • Automatic HTTPS and an ingress shield in front of every domain.
  • Deploys are gated on the health check before traffic switches.
  • One-step rollback to the previous revision.
  • Exposure report shows what is reachable from outside.
  • Host firewall rules managed for published ports.
