Dependencies

Depends on:
  • gcp/gke (required) — Kubernetes cluster
Depended on by:
  • agno/runner creates Kubernetes Deployments internally

​
Example

provider: kubernetes
resource: deployment
name: my-app
config:
  cluster:
    provider: gcp
    resource: gke
    name: my-cluster
  namespace: production
  replicas: 3
  selector:
    app: my-app
  containers:
    - name: app
      image: gcr.io/my-project/my-app:latest
      ports:
        - container_port: 8080
          name: http
      env:
        APP_ENV: production
      resources:
        cpu: "500m"
        memory: "512Mi"
        cpu_limit: "1"
        memory_limit: "1Gi"
      readiness_probe:
        http_get:
          path: /health
          port: 8080
        period_seconds: 5
  strategy: RollingUpdate

Notes

  • The deployment waits up to 5 minutes for all replicas to become ready before timing out.
  • The cluster, namespace, and selector fields are immutable — changing them requires deleting and recreating the resource.
  • Environment variables from Kubernetes Secrets use the format "secret_name.key" in env_from_secret.
  • Rolling updates use 25% max surge and 25% max unavailable by default.
