Error upgrading Podman

If you are using Podman Desktop, you are in fact using a combination of 2 tools. One is Podman, an open source container, pod, and container image management engine.

The other is Podman Desktop itself which is a graphical layer on top of Podman (and other container engines).

Podman Logo

This means that you can use different versions of Podman in combination with different versions of Podman Desktop.  For example, as you can see in the screenshot below I’m using version 5.2.0 of Podman whereas my Podman Desktop version is v1.12.0.

Error: vm "podman-machine-default" already exists on hypervisor

Today after upgrading Podman, Podman Desktop started to return the following error message when I tried to initialize the podman virtual machine:

Error: vm "podman-machine-default" already exists on hypervisor


I tried to fix it by removing the virtual machine distribution from wsl:

wsl --unregister podman-machine-default

When I tried to initialize the podman virtual machine again, it failed again but with a different error message:

Error extracting compressed file: \"unexpected EOF\"" Error: unexpected EOF

To fix that problem I had to reset the virtual machine:

podman.exe machine reset
Warning: this command will delete all existing Podman machines and all of the configuration and data directories for Podman machines
The following machine(s) will be deleted:

Are you sure you want to continue? [y/N]

Now I could re-download and initialize the virtual machine successfully:

podman.exe machine init
Downloading VM image: v20240728061533-5.1-rootfs-amd64.tar.zst: done
Extracting compressed file: podman-machine-default-amd64: done
Importing operating system into WSL (this may take a few minutes on a new WSL install)...
Import in progress, this may take a few minutes.
The operation completed successfully.

To start your machine run: podman machine start

.NET 8–Keyed/Named Services

A feature that a lot of IoC container libraries support but that was missing in the default DI container provided by Microsoft is the support for Keyed or Named Services. This feature allows you to register the same type multiple times using different names, allowing you to resolve a specific instance based on the circumstances. Although there is some controversy if supporting this feature is a good idea or not, it certainly can be handy. To support this feature a new interface IKeyedServiceProvider got introduced in .NET 8 providing 2 new methods on our ServiceProvider instance: object? GetKeyedService(Type serviceType, object? serviceKey); object GetRequiredKeyedService(Type serviceType, object? serviceKey); To use it, we need to register our service using one of the new extension methods: Resolving the service can be done either through the FromKeyedServices attribute: or by injecting the IKeyedServiceProvider interface and calling the GetRequiredKeyedServic...

Kubernetes–Limit your environmental impact

Reducing the carbon footprint and CO2 emission of our (cloud) workloads, is a responsibility of all of us. If you are running a Kubernetes cluster, have a look at Kube-Green . kube-green is a simple Kubernetes operator that automatically shuts down (some of) your pods when you don't need them. A single pod produces about 11 Kg CO2eq per year( here the calculation). Reason enough to give it a try! Installing kube-green in your cluster The easiest way to install the operator in your cluster is through kubectl. We first need to install a cert-manager: kubectl apply -f https://github.com/cert-manager/cert-manager/releases/download/v1.14.5/cert-manager.yaml Remark: Wait a minute before you continue as it can take some time before the cert-manager is up & running inside your cluster. Now we can install the kube-green operator: kubectl apply -f https://github.com/kube-green/kube-green/releases/latest/download/kube-green.yaml Now in the namespace where we want t...
