Next, install the Kubernetes dashboard by running the kubectl apply command as shown below. 1. 6. The view lists applications by workload kind (for example: Deployments, ReplicaSets, StatefulSets). But now, you should know that the Kubernetes dashboard pod can do anything a cluster administrator can do. Ensure that you're either a cluster administrator or a user with the appropriate permissions to access the AKS cluster. To deploy it, run the following command: To protect your cluster data, Dashboard deploys with a minimal RBAC configuration by default. The resources include: In this example, we'll use our sample AKS cluster to deploy the Azure Vote application from the AKS quickstart. internal endpoints for cluster connections and external endpoints for external users. See Deployments and YAML manifests for a deeper understanding of cluster resources and the YAML files that are accessed with the Kubernetes resource viewer. This manifest defines a service account and cluster role binding named You can specify additional labels to be applied to the Deployment, Service (if any), and Pods, kubectl delete clusterrolebinding kubernetes-dashboard -n kube-system kubectl create clusterrolebinding kubernetes-dashboard --clusterrole=cluster-admin --serviceaccount=kube-system:kubernetes-dashboard You will now notice that the service type has changed to NodePort, and the service exposes the pods internal TCP port 30265 using the outside TCP port of 443. Prometheus is an open source project that was originally created at SoundCloud in 2012, and contributed to the Cloud Native Computing Foundation (CNCF) in 2016 as the second open source software project after Kubernetes itself.
