This tutorial uses. How I reduced the docker image size by up to 70%? 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. If the name is set as a number, such as 10, the pod will be put in the default namespace. The Azure Portal Kubernetes management capabilities and the YAML editor are built for learning and flighting new deployments in a development and testing setting. / customized version of Ghostwriter theme by JollyGoodThemes Kubernetes Dashboard is the official web-based UI for Kubernetes user interface, consisting of a group of resources to simplify cluster management. The Helm chart readme has detailed information and examples. Dashboard offers all available secrets in a dropdown list, and allows you to create a new secret. The Azure CLI will automatically open the Kubernetes dashboard in your default web-browser. environment variables. From the Kubernetes resources view, users can see the live status of individual deployments, including CPU and memory usage, as well as transition to Azure monitor for more in-depth information about specific nodes and containers. Now, if you run the kubectl get command again you will see the deployment kubernetes-dashboard has gone. The UI can only be accessed from the machine where the command is executed. The namespace name may contain a maximum of 63 alphanumeric characters and dashes (-) but can not contain capital letters. The container image specification must end with a colon.

Since AKS is a managed Kubernetes service, it doesnt allow you to see internal components such as the etcd store, the controller manager, the scheduler, etc. You will use the public IP address for the control plane node, the username, and add the private key you used when creating the cluster. You can specify the minimum resource limits To complete this task, you need to install Azure CLI on your machine and install Web UI on your AKS cluster. Authenticate to the cluster we have just created. Each workload kind can be viewed separately. you can define your application in one or more manifests, and upload the files using Dashboard.
