Dell Container Storage Modules (CSM) for Observability Helm deployment

The Container Storage Modules (CSM) for Observability Helm chart bootstraps an Observability deployment on a Kubernetes cluster using the Helm package manager.

Prerequisites

  • Helm 3.x
  • The deployment of one or more supported Dell CSI drivers

Install the CSM for Observability Helm Chart

Steps

  1. Create a namespace where you want to install the module

    kubectl create namespace karavi
    
  2. Install cert-manager CRDs

    
    kubectl apply --validate=false -f https://github.com/jetstack/cert-manager/releases/download/v1.10.0/cert-manager.crds.yaml
    
  3. Add the Dell Helm Charts repo

      helm repo add dell https://dell.github.io/helm-charts
    
  4. Copy only the deployed CSI driver entities to the Observability namespace

    PowerFlex

    1. Copy the config Secret from the CSI PowerFlex namespace into the CSM for Observability namespace:

      
      kubectl get secret vxflexos-config -n [CSI_DRIVER_NAMESPACE] -o yaml | sed 's/namespace: [CSI_DRIVER_NAMESPACE]/namespace: [CSM_NAMESPACE]/' | kubectl create -f -
      

      If the CSI driver secret name is not the default vxflexos-config, please use the following command to copy secret:

  5. Configure the parameters and install the CSM for Observability Helm Chart

    A default values.yaml file is located here that can be used for installation. This can be copied into a file named myvalues.yaml and either used as is or modified accordingly.

    Note:

    • The default values.yaml is configured to deploy the CSM for Observability Topology service on install.
    • If CSM for Authorization is enabled for CSI PowerFlex, the karaviMetricsPowerflex.authorization parameters must be properly configured in your values file for CSM Observability.
    • If CSM for Authorization is enabled for CSI PowerScale, the karaviMetricsPowerscale.authorization parameters must be properly configured in your values file for CSM Observability.
    • If CSM for Authorization is enabled for CSI PowerMax, the karaviMetricsPowerMax.authorization parameters must be properly configured in your values file for CSM Observability.
    
    helm install karavi-observability dell/karavi-observability -n [CSM_NAMESPACE] -f myvalues.yaml
    

    Alternatively, you can specify each parameter using the ‘–set key=value[,key=value]’ and/or ‘–set-file key=value[,key=value] arguments to ‘helm install’. For example:

    
    helm install karavi-observability dell/karavi-observability -n [CSM_NAMESPACE] \
    --set-file karaviTopology.certificateFile=<location-of-karavi-topology-certificate-file> \
    --set-file karaviTopology.privateKeyFile=<location-of-karavi-topology-private-key-file> \
    --set-file otelCollector.certificateFile=<location-of-otel-collector-certificate-file> \
    --set-file otelCollector.privateKeyFile=<location-of-otel-collector-private-key-file>
