Application Delivery

An ApplicationSet groups services on a ReleaseTrack; an Application (built from source) or ExternalApplication (prebuilt image) defines the service; a DeploymentConfig tunes it per environment.

ApplicationSet​

# .../release-track/main-track/application-set/payments/payments.yaml
apiVersion: lowops.manifests.v1
kind: ApplicationSet
metadata:
  name: payments
  release-track: main-track
  organizational-unit: retail-banking
  organization: fincorp
spec:
  description: "Core payment services released together."

Application (built from a BuildDefinition)​

# .../application-set/payments/application/payment-api.yaml
apiVersion: lowops.manifests.v1
kind: Application
metadata:
  name: payment-api
  application-set: payments
  release-track: main-track
  organizational-unit: retail-banking
  organization: fincorp
spec:
  description: "Payment processing API."
  target: CLOUD_RUN                # CLOUD_RUN | KUBERNETES | COMPUTE
  meshStrategy: DISABLED           # SIDECAR | PROXYLESS | DISABLED
  source: payment-api              # a BuildDefinition
  container: payment-api           # a container produced by that BuildDefinition
  project: login-svc

ExternalApplication (prebuilt image)​

# .../application-set/payments/external-application/httpbin.yaml
apiVersion: lowops.manifests.v1
kind: ExternalApplication
metadata:
  name: httpbin
  application-set: payments
  release-track: main-track
  organizational-unit: retail-banking
  organization: fincorp
spec:
  description: "Diagnostic echo service."
  target: CLOUD_RUN
  meshStrategy: SIDECAR
  source: docker-io                # an ExternalRegistry
  container: mccutchen/go-httpbin  # the image within that registry
  project: login-svc

DeploymentConfig (per environment)​

The metadata.name must match the application's name. Create one per environment to vary version, env vars, scaling, ports, and health.

# .../environment/prod/project/login-svc/deployment-config/payment-api.yaml
apiVersion: lowops.manifests.v1
kind: DeploymentConfig
metadata:
  name: payment-api               # matches the Application name
  project: login-svc
  environment: prod
  organizational-unit: retail-banking
  organization: fincorp
spec:
  version: v1.4.0
  container:
    env:
      - name: LOG_LEVEL
        value: info
  ports:
    8080: http
  scaling:
    min: 2
    max: 10
  health:
    liveness:
      protocol: HTTP
      port: 8080
      path: /healthz
