→‎Creating your own images
Regel 949: Regel 949:
To begin with, the registry will need storage for its images. True to our earlier experiments, we start by creating a persistent volume claim. (I'll assume there's a persistent volume to fulfill it; if not, check above how to create one yourself.)

<pre>
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: registry-files
spec:
  storageClassName: default
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 20Gi
</pre>


The registry deployment:


To do: Set up Docker Registry. Push images to it. Start them in a pod.
<pre>
apiVersion: apps/v1
kind: Deployment
metadata:
  name: registry
spec:
  selector:
    matchLabels:
      app: registry
  replicas: 1
  template:
    metadata:
      labels:
        app: registry
    spec:
      volumes:
      - name: registrystorage
        persistentVolumeClaim:
          claimName: registry-files
      containers:
      - name: registry
        image: registry:2
        ports:
        - containerPort: 5000
        volumeMounts:
        - mountPath: /var/lib/registry
          name: registrystorage
</pre>
 
And a Service + Ingress to make it accessible on a new hostname. I found that Docker doesn't support accessing a registry with a path prefix, so we have to give it its own hostname. Luckily, with Traefik, it's easy to route; you'll only have to add a record in DNS.
 
<pre>
apiVersion: v1
kind: Service
metadata:
  name: registry-service
spec:
  selector:
    app: registry
  ports:
    - name: registry
      port: 5000
      protocol: TCP
---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: registry-ingress
spec:
  rules:
  - host: kuberegistry.sjorsgielen.nl
    http:
      paths:
      - path: /
        backend:
          serviceName: registry-service
          servicePort: 5000
</pre>
 
After a minute, as before, https://kuberegistry.sjorsgielen.nl/v2/ (replace with your own hostname) should return 200 OK with a page content of "{}".
