IBM Cloud
Improve your IBM Cloud infrastructure monitoring by integrating Prometheus. This straightforward guide walks you through the configuration process, making it simpler and more user-focused. Let’s jump right in!
Initial setup and tool installation
- Begin by installing the ibmcloud tool on your machine. Get it here.
- If you're using an RHEL machine, opt for this version: RHEL ibmcloud tool.
Plugin installation
- Enhance the functionality of the ibmcloud tool by installing the following plugins:
- ibmcloud plugin install container-service
- ibmcloud plugin install container-registry
- ibmcloud plugin install observe-service
Connection and configuration
- Ensure kubectl is installed on your system.
- Connect to the IBM Cloud CLI with this command: ibmcloud login -a cloud.ibm.com -r jp-tok -g Default --sso (Note: Include --sso only if you're using a federated ID.)
- To focus on your specific cluster for this session, use: ibmcloud ks cluster config --cluster c50pifut05bcc7pangi0.
- Check if the connection to your cluster is successfully established: kubectl config current-context.
Integrating Prometheus with IBM Cluster
- Ensure the Helm package manager for Kubernetes is installed. Helm streamlines Prometheus installation and management.
- Next, add the Prometheus repository to your Helm list and update it:
csharpCopy codehelm repo add prometheus-community https://prometheus-community.github.io/helm-charts
helm repo update- Install the Prometheus Helm chart into the 'monitoring' namespace (this will be created automatically if it does not exist): helm install prometheus prometheus-community/kube-prometheus-stack --namespace monitoring --create-namespace.
- Validate Prometheus installation by checking the status of the pods: kubectl --namespace monitoring get pods -l "release=prometheus".
Dive into Prometheus dashboard
- Access the Prometheus dashboard on IBM cluster using port forwarding: kubectl port-forward --namespace monitoring svc/prometheus-kube-prometheus-prometheus 9090.
