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
