Configure Log forwarding from VMware Tanzu Kubernetes Cluster to vRealize Log Insight Cloud

What is VMware Tanzu Kubernetes Grid

Standalone VMware Tanzu Kubernetes Grid provides organizations with a consistent, upstream-compatible, regional Kubernetes substrate across software-defined datacenters (SDDC) and public cloud environments, that is ready for end-user workloads and ecosystem integrations

 

With vRealize Log Insight Cloud we support number of Log Sources and you will see instructions for VMware Tanzu Kubernetes Grid  as well

 

Once the logs are flowing you can create a Dashboard to visualize your TKG environment like the below sample dashboard

Pre-requisites

Working Setup of Tanzu Kubernetes Cluster following the documentation or using the fling (Demo Appliance for Tanzu Kubernetes Grid) created by our friend William Lam 

I have used Demo Appliance for Tanzu Kubernetes Grid in my lab

Procedure

The following section includes steps for running vRealize Log Insight Cloud Fluentd plugin as a Daemon set

Step 1

Generate vRealize Log Insight Cloud API Key from here 

Step2

 

Copy following files from the shared repo https://github.com/munishpalmakhija/tkg-demos/tree/master/vrealize/loginsight-cloud

  • fluent.conf
  • vrlic.yaml

For the next release of the Demo Appliance, these files will be automatically be downloaded under the vRealize folder since it has been merged in the official repo of the Demo Appliance

Step 3

Update the fluent.conf file with the given configuration. You only need to update <Access Key> : generated in Step 1

Step 4

Create a ConfigMap in Kubernetes for fluent.conf

kubectl -n kube-system create configmap lint-fluent-config --from-file=fluent.conf

Step 5

Apply the creation/changes of new daemon set configuration to the cluster

kubectl apply -f vrlic.yaml

You can verify that pod is successfully running

kubectl get pods --all-namespaces | grep fluentd

If everything is successful you can search for logs using “environment contains tanzu_k8s_grid”
