Rancher Desktop provides Kubernetes and container management for Mac, Windows and Linux. Moreover it gives the ability to build, push, and pull images via the nerdctl project, which we can use to check namespaces and images downloaded just after installing Rancher Desktop:

> nerdctl namespace ls
NAME        CONTAINERS    IMAGES    VOLUMES
buildkit    0             0         0
k8s.io      22            16        0

> nerdctl images --namespace k8s.io

Using Dockerfile for simple application image can be built:

> nerdctl build --tag python-localstack-client -f app/Dockerfile .

> nerdctl namespace ls
NAME        CONTAINERS    IMAGES    VOLUMES
buildkit    0             0         0
default     0             1         0
k8s.io      22            16        0

> nerdctl images
REPOSITORY                  TAG       IMAGE ID        CREATED           PLATFORM       SIZE
python-localstack-client    latest    90019635255f    20 seconds ago    linux/arm64    300.3 MiB

Then container in Rancher Desktop can be started:

> nerdctl run --name python-localstack-client --rm python-localstack-client

> nerdctl ps -a
