Google's GKE

Effortlessly optimize your GKE cluster with KRS. This powerful tool, running locally on your machine, analyzes your GKE cluster for improvement. Leverage KRS to gain valuable insights and recommendations for a smoother Kubernetes experience.

Prerequisite

• A Google Cloud Account
• Installing Google Cloud SDK on your macOS

Getting Started

1. Execute the following command to install Google Cloud SDK in your system

   tar xfz google-cloud-sdk-195.0.0-darwin-x86_64.tar.gz
   ./google-cloud-sdk/install.sh
   

2. Enable Google Cloud Engine API

   

3. Authenticate Your Google Cloud using gcloud auth

   gcloud init
   

   In your browser, log in to your Google user account when prompted and click Allow to grant permission to access Google Cloud Platform resources.

4. Creating GKE Cluster

   gcloud container clusters create k8s-lab1 --disk-size 10 --zone asia-east1-a --machine-type n1-standard-2 --num-nodes 3 --scopes compute-rw
   

5. Viewing it on Google Cloud Platform

   

6. Viewing the new context on Docker Desktop

   

7. Verifying the Google Kubernetes Cluster

   kubectl get nodes
   NAME                                      STATUS   ROLES    AGE    VERSION
   gke-k8s-lab1-default-pool-5dfb7153-3fr7   Ready    <none>   3m1s   v1.29.4-gke.1043002
   gke-k8s-lab1-default-pool-5dfb7153-nl3v   Ready    <none>   3m1s   v1.29.4-gke.1043002
   gke-k8s-lab1-default-pool-5dfb7153-rkg8   Ready    <none>   3m2s   v1.29.4-gke.1043002
   

8. Initialize the KRS

   krs init
   Services initialized and scanner loaded.
   

9. Running the scanner

   krs scan
   
   Scanning your cluster...
   
   Cluster scanned successfully...
   
   Extracted tools used in cluster...
   
   
   The cluster is using the following tools:
   
   +-------------+--------+-----------------------------+---------------+
   | Tool Name   |   Rank | Category                    | CNCF Status   |
   +=============+========+=============================+===============+
   | autoscaler  |      5 | Cluster with Core CLI tools | unlisted      |
   +-------------+--------+-----------------------------+---------------+
   | fluentbit   |      4 | Logging and Tracing         | unlisted      |
   +-------------+--------+-----------------------------+---------------+
   

10. Checking the Krs Recommendation

    krs recommend
    
    Our recommended tools for this deployment are:
    
    +-----------------------------+------------------+-------------+---------------+
    | Category                    | Recommendation   | Tool Name   | CNCF Status   |
    +=============================+==================+=============+===============+
    | Cluster with Core CLI tools | Recommended tool | k9s         | unlisted      |
    +-----------------------------+------------------+-------------+---------------+
    | Logging and Tracing         | Recommended tool | elk         | unlisted      |
    

11. Installing Kubeview

    git clone https://github.com/benc-uk/kubeview
    cd kubeview/charts/
    helm install kubeview kubeview
    

12. Running the scanner again

    krs scan
    
    Scanning your cluster...
    
    Cluster scanned successfully...
    
    Extracted tools used in cluster...
    
    
    The cluster is using the following tools:
    
    +-------------+--------+-----------------------------+---------------+
    | Tool Name   |   Rank | Category                    | CNCF Status   |
    +=============+========+=============================+===============+
    | kubeview    |     30 | Cluster with Core CLI tools | unlisted      |
    +-------------+--------+-----------------------------+---------------+
    |             |      3 | Cluster Management          | unlisted      |
    +-------------+--------+-----------------------------+---------------+
    | autoscaler  |      5 | Cluster with Core CLI tools | unlisted      |
