Setup the Kubernetes dashboard on Docker for Windows

A useful tool when you are new to Kubernetes is the Kubernetes Dashboard.

Unfortunately the Kubernetes Dashboard is not included out-of-the-box with Docker for Windows however it can be easily setup for your local cluster.

To setup the dashboard use the following command:

kubectl apply -f 
https://raw.githubusercontent.com/kubernetes/dashboard/v1.10.1/src/deploy/recommended/kubernetes-dashboard.yaml 
The output should look like this:

secret/kubernetes-dashboard-certs created
serviceaccount/kubernetes-dashboard created
role.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
rolebinding.rbac.authorization.k8s.io/kubernetes-dashboard-minimal created
deployment.apps/kubernetes-dashboard created
service/kubernetes-dashboard created

To view the Dashboard in your web browser run:

kubectl proxy

And nagivate to your Kubernetes Dashboard at:

http://localhost:8001/api/v1/namespaces/kube-system/services/https:kubernetes-dashboard:/proxy/.

The first time you open the dashboard you have to enter an authentication token.

Creating an authorization token

To create an authorization token, we first need a Service Account:

kubectl create serviceaccount admin-user

Now we need a clusterrolebinding to assign the ClusterRole to the created admin-user:

kubectl create clusterrolebinding cluster-admin-binding --clusterrole cluster-admin --user admin-user

Check an associated secret:

kubectl get serviceaccounts admin-user -o yaml

As a last step we need to request the secret data:

kubectl describe secret admin-user-token-5s5rv

Now you can copy and past the generated token in the Token field.

Podman– Command execution failed with exit code 125

After updating WSL on one of the developer machines, Podman failed to work. When we took a look through Podman Desktop, we noticed that Podman had stopped running and returned the following error message: Error: Command execution failed with exit code 125 Here are the steps we tried to fix the issue: We started by running podman info to get some extra details on what could be wrong: >podman info OS: windows/amd64 provider: wsl version: 5.3.1 Cannot connect to Podman. Please verify your connection to the Linux system using `podman system connection list`, or try `podman machine init` and `podman machine start` to manage a new Linux VM Error: unable to connect to Podman socket: failed to connect: dial tcp 127.0.0.1:2655: connectex: No connection could be made because the target machine actively refused it. That makes sense as the podman VM was not running. Let’s check the VM: >podman machine list NAME         ...

VS Code Planning mode

After the introduction of Plan mode in Visual Studio , it now also found its way into VS Code. Planning mode, or as I like to call it 'Hannibal mode', extends GitHub Copilot's Agent Mode capabilities to handle larger, multi-step coding tasks with a structured approach. Instead of jumping straight into code generation, Planning mode creates a detailed execution plan. If you want more details, have a look at my previous post . Putting plan mode into action VS Code takes a different approach compared to Visual Studio when using plan mode. Instead of a configuration setting that you can activate but have limited control over, planning is available as a separate chat mode/agent: I like this approach better than how Visual Studio does it as you have explicit control when plan mode is activated. Instead of immediately diving into execution, the plan agent creates a plan and asks some follow up questions: You can further edit the plan by clicking on ‘Open in Editor’: ...
