Private Docker Registry in DigitalOcean Kubernetes with s3 storage in Spaces

№ 10420 В разделе "Администрирование" от December 4th, 2019,

Prepare Configmap with auth information. Use command htpasswd -Bbn vlad 123 to create login and password for users. No need to restart all pods of registry to apply changes. May be you want to store it in Secret resource, at your choice.

Example:

---
apiVersion: v1
kind: ConfigMap
metadata:
  creationTimestamp: null
  name: registry-auth
data:
  htpasswd: |
    vlad:$2y$05$anFCx3pAPG/BNxPsEKcau.LPKjWFN7hHkoXbvIMp7Jie97uYafuSq

Now create bucket my-own-registry in Spaces with access key id and secret key. Do not forget to set http_secret and nodeSelector. http_secret required if you want multiple pods.

Example:

---
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: registry
spec:
  replicas: 2
  template:
    metadata:
      labels:
        name: registry
    spec:
      containers:
      - name: registry
        image: registry:2
        ports:
        - name: registry
          containerPort: 5000
        volumeMounts:
        - mountPath: /auth
          name: auth
        env:
        - name: REGISTRY_HEALTH_STORAGEDRIVER_ENABLED
          value: "false"
        - name: REGISTRY_AUTH
          value: "htpasswd"
        - name: REGISTRY_AUTH_HTPASSWD_REALM
          value: "Registry Realm"
        - name: REGISTRY_AUTH_HTPASSWD_PATH
          value: /auth/htpasswd
        - name: REGISTRY_STORAGE
          value: "s3"
        - name: REGISTRY_STORAGE_S3_ACCESSKEY
          value: "TVV3WXZ233MEPEBXFP7X"
        - name: REGISTRY_STORAGE_S3_SECRETKEY
          value: "ERlofd+hb9Ps1oBR5jUJuPa9NIMRSLxvUyulKJnt8S0"
        - name: REGISTRY_STORAGE_S3_BUCKET
          value: "my-own-registry"
        - name: REGISTRY_STORAGE_S3_REGION
          value: "fra1"
        - name: REGISTRY_STORAGE_S3_REGIONENDPOINT
          value: "https://fra1.digitaloceanspaces.com"
        - name: REGISTRY_LOG_LEVEL
          value: "info"
        - name: REGISTRY_HTTP_ADDR
          value: "0.0.0.0:5000"
        - name: REGISTRY_HTTP_SECRET
          value: sexy_pony
        resources:
          limits:
            cpu: 100m
            memory: 200Mi
          requests:
            cpu: 50m
            memory: 50Mi
      volumes:
      - name: auth
        configMap:
          name: registry-auth
      nodeSelector:
        doks.digitalocean.com/node-pool: infra

Last step easily shares registry. Set limit for image size in proxy-body-size, value 0 means no limits.

Example:

---
apiVersion: v1
kind: Service
metadata:
  name: registry
  labels:
    name: registry
spec:
  ports:
  - port: 80
    targetPort: registry
    protocol: TCP
    name: registry
  selector:
    name: registry
  type: ClusterIP

---
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    certmanager.k8s.io/cluster-issuer: letsencrypt-prod
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/proxy-body-size: "0"
  name: registry
spec:
  rules:
  - host: registry.k8s.blindage.org
    http:
      paths:
      - backend:
          serviceName: registry
          servicePort: registry
        path: /
  tls:
  - hosts:
    - k8s.blindage.org
    - '*.k8s.blindage.org'
    secretName: k8s-blindage-tls

Хорошая шпаргалка по пластикам для печати drive.google.com/file/d/1NKB3- В принципе, данные практически сходятся с моими blindage.org/?p=10199
