Customizing Logging Stack Applications

This page provides instructions on how you can customize the Logging Stack Applications in DKP.

Retrieve the Workspace Namespace

1. On the Management Cluster, execute the following command to get the namespace of your workspace:

   CODE

   dkp get workspaces

2. Copy the value under the NAMESPACE column for your workspace.

3. Set the WORKSPACE_NAMESPACE variable to the namespace copied in the previous step

How to customize Logging Stack Applications

1. On the Attached or Managed Cluster, retrieve the kubeconfig for the cluster.

2. Apply the ConfigMap directly to the managed/attached cluster using the name, logging-operator-logging-overrides:

   CODE

   cat <<EOF | kubectl apply -f -
   apiVersion: v1
   kind: ConfigMap
   metadata:
     name: logging-operator-logging-overrides
     namespace: ${WORKSPACE_NAMESPACE}
   data:
     values.yaml: |
       <insert config here>
   EOF

Customized ConfigMap Example

This is an example of an ConfigMap that contains customized resource request and limit values for fluentd:

apiVersion: v1
kind: ConfigMap
metadata:
  name: logging-operator-logging-overrides
  namespace: kommander
data:
  values.yaml: |
    fluentd:
      resources:
        limits:
          cpu: 1
          memory: 2000Mi
        requests:
          cpu: 1
          memory: 1500Mi
