ISD Architecture
The figure below depicts the component view of the ISD architecture. As mentioned earlier, it consists of two modules, Orchestration and the Data & Intelligence module.
ISD consists of the following services.
- 1.Autopilot = Verification service
- 2.SAPOR = Connect with Spinnaker and git/S3 Repo for updating dynamic accounts
- 3.Visibility = Implementation of approval service
- 4.Dashboard = Collate data for graphical presentation of applications and pipelines
- 5.OES-Gate = Authentication gateway
- 6.Sapor-gate = OPTIONAL: spin-gate with basic-auth for Sapor communication
- 7.Controller = OPTIONAL: remote deployments (Not shown in the Schematic below)
- 8.OES-UI = Serves the UI elements (Not shown in the Schematic below)
These services also use two databases:
- 1.OES-db : Postgres DB customized for OES
- 2.OES-redis : Used by OES-gate
Apart from these, OES includes all the Spinnaker components, configured in HA mode. Spinnaker services functional roles are as follows:
- Deck (GUI)
- Gate (API)
- Clouddriver (Deployments)
- Orca (Orchestrator)
- Echo (Notifications)
- Front50 (DB Frontend)
- Redis (Execution cache)
Key communication paths in the ISD:
- 1.SAPOR Service communicates with the Spinnaker Gateway and makes API calls to retrieve data, update pipelines, etc.
- 2.SAPOR can also be configured to use Sapor-gate which uses Basic Authentication. This is useful in cases where Spinnaker is configured with 2-factor authentication.
- 3.Application is designed based on API-gateway architecture. All data from the web-browser goes through:
- OES-gate or
- Spin-gate
ISD requires 5 ingress points:
- 1.Spinnaker UI : spin-deck service on port 9000
- 2.Spinnaker Gate: spin-gate service on port 8084
- 3.OES UI: OES-UI service on port 8080
- 4.OES gate: OES-API service on port 8084
- 5.Controller: For an agent to contact the controller, we need an ingress/LB. Note that TLS + gRPC traffic needs to be routed to the controller, shown in red.
