Artifact Hub

This page contains a few copy/paste-ready examples for common component-chart scenarios.

Example: Basic web API (Deployment + Service)​

containers:
  - name: demo
    image: nginx
    imageTag: "latest"

service:
  ports:
    - port: 80

Example: Ingress with TLS (cert-manager)​

containers:
  - name: api
    image: mendhak/http-https-echo
    imageTag: "38"

service:
  ports:
    - port: 8080

ingress:
  certmanager: true
  ingressClassName: nginx
  rules:
    - host: api.example.com
      path: /
      servicePort: 80
  tls: true
  tlsClusterIssuer: lets-encrypt-http-issuer

Example: Persistent volume (StatefulSet) + mount​

When at least one writable volume is mounted into a container, the chart switches to a StatefulSet and uses a headless serviceName.

serviceName: my-app

containers:
  - name: postgres
    image: postgres
    imageTag: "17"
    volumeMounts:
      - containerPath: /var/lib/postgresql/data
        volume:
          name: data
          readOnly: false

volumes:
  - name: data
    size: 10Gi

Example: ExternalSecret (External Secrets Operator) + mount via volume secret​

This creates the ExternalSecret resource which in turn creates a Kubernetes Secret (target.name). You can then reference/mount that Secret using volumes.

externalSecrets:
  - name: app-secrets
    refreshInterval: "1h"
    secretStoreRef:
      name: my-secret-store
      kind: SecretStore
    target:
      name: app-secrets
      creationPolicy: Owner
    data:
      - secretKey: DATABASE_URL
        remoteRef:
          key: /prod/app/database_url

containers:
  - name: api
    image: mendhak/http-https-echo
    imageTag: "38"
    volumeMounts:
      - containerPath: /etc/secrets
        volume:
          name: app-secrets
          readOnly: true

volumes:
  - name: app-secrets
    secret:
      secretName: app-secrets

Example: Create a ServiceAccount​

serviceaccount:
  name: my-app
  annotations:
    eks.amazonaws.com/role-arn: arn:aws:iam::123456789012:role/my-app

containers:
  - name: api
    image: mendhak/http-https-echo
    imageTag: "38"

Example: Create a ConfigMap + consume via env​

configmap:
  name: api
  data:
    LOG_LEVEL: info

containers:
  - name: api
    image: mendhak/http-https-echo
    imageTag: latest
    envFrom:
      - configMapRef:
          name: api

Example: Render extraObjects verbatim​

containers:
  - name: api
    image: mendhak/http-https-echo
    imageTag: "38"

extraObjects:
  - apiVersion: policy/v1
    kind: PodDisruptionBudget
    metadata:
      name: my-app
    spec:
      minAvailable: 1
      selector:
        matchLabels:
          app.kubernetes.io/name: devspace-app
          app.kubernetes.io/component: my-app
