I want to setup checkmk in kubernetes cluster, please guide if any additional document i need to follow to configure checkmk server in kubernetes cluster to access GUI and connect with collectors to get the metrics…
In that case, you have to follow this Deploying Checkmk in Kubernetes | Checkmk . Once Checkmk monitoring instance has been deployed in your K8 setup (please read the disclaimer as well) then you just need to follow the Youtube tutorial to configure the connection to the cluster-collector.
