#Install Via YAML

#When to Use This Method?

Recommended for:

• Advanced users with Kubernetes expertise who prefer a manual approach.
• Production-grade deployments requiring enterprise storage (NAS, AWS S3, Ceph, etc.).
• Environments needing fine-grained control over TLS, ingress.
• Full YAML customization for advanced configurations.

#Prerequisites

• Install the Alauda Container Platform Registry cluster plugin to a target cluster.
• Access to the target Kubernetes cluster with kubectl configured.
• Cluster admin permissions to create cluster-scoped resources.
• Obtain a registered domain (e.g., registry.yourcompany.com) Create a Domain
• Provide valid NAS storage (e.g., NFS, GlusterFS, etc.).
• (Optional) Provide valid S3 storage (e.g., AWS S3, Ceph, etc.). If no existing S3 storage is available, deploy a MinIO (Built-in S3) instance in the cluster Deploy MinIO.

#Installing Alauda Container Platform Registry via YAML

#Procedure

1. Create a YAML configuration file named registry-plugin.yaml with the following template:

   apiVersion: cluster.alauda.io/v1alpha1
   kind: ClusterPluginInstance
   metadata:
     annotations:
       cpaas.io/display-name: internal-docker-registry
     labels:
       create-by: cluster-transformer
       manage-delete-by: cluster-transformer
       manage-update-by: cluster-transformer
     name: internal-docker-registry
   spec:
     config:
       access:
         address: ""
         enabled: false
       fake:
         replicas: 2
       global:
         expose: false
         isIPv6: false
         replicas: 2
         resources:
           limits:
             cpu: 500m
             memory: 512Mi
           requests:
             cpu: 250m
             memory: 256Mi
       ingress:
         enabled: true
         hosts:
           - name: <YOUR-DOMAIN>   # [REQUIRED] Customize domain
             tlsCert: <NAMESPACE>/<TLS-SECRET>  # [REQUIRED] Namespace/SecretName
         ingressClassName: "<INGRESS-CLASS-NAME>"  # [REQUIRED] IngressClassName
         insecure: false
       persistence:
         accessMode: ReadWriteMany
         nodes: ""
         path: <YOUR-HOSTPATH>  # [REQUIRED] Local path for LocalVolume
         size: <STORAGE-SIZE>  # [REQUIRED] Storage size (e.g., 10Gi)
         storageClass: <STORAGE-CLASS-NAME>  # [REQUIRED] StorageClass name
         type: StorageClass
       s3storage:
         bucket: <S3-BUCKET-NAME>             # [REQUIRED] S3 bucket name
         enabled: false                        # Set false for local storage
         env:
           REGISTRY_STORAGE_S3_SKIPVERIFY: false  # Set true for self-signed certs
         region: <S3-REGION>                        # S3 region
         regionEndpoint: <S3-ENDPOINT>  # S3 endpoint
         secretName: <S3-CREDENTIALS-SECRET>             # S3 credentials Secret
       service:
         nodePort: ""
         type: ClusterIP
     pluginName: internal-docker-registry

2. Customize the following fields according to your environment:

   spec:
     config:
       ingress:
         hosts:
           - name: "<YOUR-DOMAIN>"                # e.g., registry.your-company.com
             tlsCert: "<NAMESPACE>/<TLS-SECRET>"   # e.g., cpaas-system/tls-secret
         ingressClassName: "<INGRESS-CLASS-NAME>"  # e.g., cluster-alb-1
       persistence:
         size: "<STORAGE-SIZE>"                    # e.g., 10Gi
         storageClass: "<STORAGE-CLASS-NAME>"      # e.g., cpaas-system-storage
       s3storage:
         bucket: "<S3-BUCKET-NAME>"                # e.g., prod-registry
         region: "<S3-REGION>"                    # e.g., us-west-1
         regionEndpoint: "<S3-ENDPOINT>"          # e.g., https://s3.amazonaws.com
         secretName: "<S3-CREDENTIALS-SECRET>"     # Secret containing AWS_ACCESS_KEY_ID/AWS_SECRET_ACCESS_KEY
         env:
           REGISTRY_STORAGE_S3_SKIPVERIFY: "true"  # Set "true" for self-signed certs

3. How to create a secret for S3 credentials:

   kubectl create secret generic <S3-CREDENTIALS-SECRET> \
     --from-literal=access-key-id=<YOUR-S3-ACCESS-KEY-ID> \
     --from-literal=secret-access-key=<YOUR-S3-SECRET-ACCESS-KEY> \
     -n cpaas-system

   Replace <S3-CREDENTIALS-SECRET> with the name of your S3 credentials secret.

4. Apply the configuration to your cluster:

   kubectl apply -f registry-plugin.yaml

#Configuration Reference

#Mandatory Fields

#Verification

1. Check plugin:

   kubectl get clusterplugininstances internal-docker-registry -o yaml

2. Verify registry pods:

   kubectl get pods -n cpaas-system -l app=internal-docker-registry

#Updating/Uninstalling Alauda Container Platform Registry

#Update

Execute the following command on the global cluster::

# <CLUSTER-NAME> is the cluster where the plugin is installed
kubectl edit -n cpaas-system \
  $(kubectl get moduleinfo -n cpaas-system -l cpaas.io/cluster-name=<CLUSTER-NAME>,cpaas.io/module-name=internal-docker-registry -o name)

#Uninstall

Execute the following command on the global cluster:

# <CLUSTER-NAME> is the cluster where the plugin is installed
kubectl get moduleinfo -n cpaas-system -l cpaas.io/cluster-name=<CLUSTER-NAME>,cpaas.io/module-name=internal-docker-registry -o name | xargs kubectl delete -n cpaas-system
