In this blog, I would like to Introduce Helm Chart which I built for vRealize LogInsight Cloud. 

It deploys fluentd as deamonset to collect logs from Kubernetes Cluster. I have verified with the following flavors 

• Tanzu Kubernetes Grid (TKG) K8 Cluster
• Vanilla K8 Clusters deployed on vSphere/AWS 

What is Helm ? 

Helm is a package manager for Kubernetes. Helm is the best way to find, share, and use software built for Kubernetes.

What are Helm charts?

Helm Charts are Kubernetes YAML manifests combined into a single package that can be deployed to on K8 environments. Once packaged, installing a Helm Chart into your cluster is as easy as running a single helm command, which simplifies the deployment & upgrade process

Architecture 

Pre-requisites 

You need to have the following pre-requisites 

1. vRealize LogInsight Cloud API Token 
2. Helm Version = \’3.x\’
3. Admin access to the Kubernetes Cluster

Installing the Chart – Procedure 1 

Step 1 – Add Chart Repo 

helm repo add loginsight-cloud https://munishpalmakhija.github.io/loginsight-cloud-helm/

Step 2 – Get Values file in your working directory 

helm show values loginsight-cloud/loginsight-cloud-helm  > values.yaml

Step 3 – Update Values file with API Token and other relevant details.  

cat values.yaml

Step 4 – Install Chart.  

helm install test-vrlic loginsight-cloud/loginsight-cloud-helm -f values.yaml

Step 5 – Verify Kubernetes Pods  

kubectl get pods -A | grep test-vrlic

Step 6 – Verify Helm Release 

helm list

Installing the Chart – Procedure 2

Step 1 – Add Chart Repo 

helm repo add loginsight-cloud https://munishpalmakhija.github.io/loginsight-cloud-helm/

Step 2 – Install Chart by setting values during run time.  

helm install test-vrlic loginsight-cloud/loginsight-cloud-helm --set vrlic.apiKey=SETME --set tag.environment=DEMO

Step 3 – Verify Kubernetes Pods  

kubectl get pods -A | grep test-vrlic

Step 4 – Verify Helm Release 

helm list
