shpod is a container image based on the Alpine distribution
and embarking a bunch of tools useful when working with Kubernetes:
- kubectx + kubens
It also includes tmux, a custom prompt, and completion for all of the above.
Its goal is to provide a normalized environment, to go with the training materials at https://container.training/, so that you can get all the tools you need regardless of your exact Kubernetes setup.
To use it, you need a Kubernetes cluster. You can use Minikube, microk8s, Docker Desktop, AKS, EKS, GKE, anything you like, really.
The shpod.sh script will:
- apply the shpod.yaml manifest to your cluster,
- wait for the pod
shpodto be ready,
- attach to that pod,
- delete resources created by the manifest when you exit the pod.
To execute it:
curl https://raw.githubusercontent.com/jpetazzo/shpod/master/shpod.sh | sh
If you don't like
curl|sh, and/or if you want to execute things
step by step, check the next section.
Deploy the shpod pod:
kubectl apply -f https://raw.githubusercontent.com/jpetazzo/shpod/master/shpod.yaml
Attach to the shpod pod:
kubectl attach --namespace=shpod -ti shpod
If you are using the shell script above, when you exit shpod, the script will delete the resources that were created.
If you want to delete the resources manually, you can use
kubectl delete -f shpod.yaml, or delete the namespace
and the ClusterRoleBinding with the same name:
kubectl delete clusterrolebinding,ns shpod
The YAML file is a Kubernetes manifest for a Pod, a ServiceAccount, a ClusterRoleBinding, and a Namespace to hold the Pod and ServiceAccount.
