Operations

The Delphi platform deploys as nine services plus a bastion host, each running on its own cloud instance. Each service has its own operations page covering runbook, configuration, and troubleshooting in tabs.

For first-boot mechanics (init.sh, S3 config sync, fetch-env.sh, and Docker Compose startup), use Bootstrap and init. This section starts once hosts exist and you need to operate or debug a specific role.

Instance vCPU and RAM are in Provision instances.

The generic docs describe the service roles and optional containers that can appear in a Delphi deployment. A customer's exact container inventory comes from the generated deployment configuration, enabled feature flags, image tag, and generated Docker Compose files. Use Release compatibility to see which service roles changed in each release; keep the customer-specific inventory with the deployment handover or runbook.

Use the cards below as the central firewall checklist by service role. They intentionally stay high-level; per-container ports and env variables live on each service page. TelPro entries marked webrtc apply only when the Featurewebrtc flag is enabled. In this platform release, those TelPro WebRTC entries are the only feature-flagged port requirements; the other flags change containers, env, or UI surfaces without adding public firewall rules.
