Update postgres resources of harbor

How to Update Harbor Advanced Parameters Using kubeopsctl

Prerequisites

Before proceeding, ensure you have:

• kubeopsctl installed and configured.
• Access to your Kubernetes cluster.
• The necessary permissions to apply changes to the Harbor deployment.

Understanding advancedParameters

Harbor allows advanced configuration via the harborValues.advancedParameters section. This section provides fine-grained control over various components, such as PostgreSQL, Redis, and logLevel, by defining resource allocations and other configurations.

Example Structure of advancedParameters

The advancedParameters section in kubeopsctl.yaml follows this structure:

harborValues:
  advancedParameters:
    postgres:
      resources:
        requests:
          memory: "512Mi"  # Minimum memory requested by PostgreSQL
          cpu: "200m"       # Minimum CPU requested by PostgreSQL
        limits:
          memory: "1Gi"     # Maximum memory PostgreSQL can use
          cpu: "500m"       # Maximum CPU PostgreSQL can use
    
    internal:
      redis:
        resources:
          requests:
            memory: "256Mi"  # Minimum memory requested by Redis
            cpu: "100m"      # Minimum CPU requested by Redis
          limits:
            memory: "512Mi"  # Maximum CPU Redis can use
            cpu: "300m"      # Maximum CPU Redis can use

    logLevel: "debug"  # Adjust logging level for debugging purposes

• postgres: Defines resource limits for the PostgreSQL database.
• redis: Configures Redis instance resources.
• logLevel: Allows setting the logging level.

Modify these values based on your cluster’s available resources and workload requirements.

Step 1: Update Your kubeopsctl.yaml Configuration

Ensure that your kubeopsctl.yaml file includes the harborValues.advancedParameters section. If necessary, update or add parameters to customize your Harbor deployment.

Step 2: Apply the Configuration with kubeopsctl

Once your kubeopsctl.yaml file is ready, apply the changes using the following command:

kubeopsctl apply -f kubeopsctl.yaml

This command updates the advanced parameters for the Harbor deployment.

Step 3: Verify the Changes

To confirm that the new configuration has been applied, run:

kubectl get pod -n <your-harbor-namespace> -o yaml | grep -A6 -i 'resources:'

Replace <your-harbor-namespace> with the namespace where Harbor is deployed.

Alternatively, describe any component to check the applied settings:

kubectl describe pod <component-pod-name> -n <your-harbor-namespace>

Conclusion

Using kubeopsctl, you can efficiently update various advanced parameters in your Harbor deployment. The advancedParameters section allows fine-tuned configuration for multiple components, ensuring optimal resource usage and performance.

If you encounter any issues, check the logs with:

kubectl logs -n <your-harbor-namespace> <component-pod-name>
