kubectl-plugins

Some of my plugins for kubectl.

Installation

Clone the repo and add it to your path (or download individual files and make sure they are executable and on your path).

For Example, to install these plugins in $HOME/kubectl-plugins, do the following:

git clone https://github.com/luksa/kubectl-plugins $HOME/kubectl-plugins
export PATH=$PATH:$HOME/kubectl-plugins

Plugins

kubectl force delete

Force deletes an object by removing its finalizers and then deleting it.

Example usage:

kubectl force delete po my-stuck-pod

kubectl really get all

Lists absolutely all resources in a namespace, not just the ones returned by kubectl get all.

Example usage:

# List all resources in the current namespace
kubectl really get all

# List all resources in the specified namespace
kubectl really get all -n my-namespace

# List all resources in the whole cluster (all cluster-scoped 
# resources and all namespaced resources in all namespaces)
kubectl really get all --all-namespaces

# List all resources in the whole cluster with the label foo=bar
kubectl really get all --selector foo=bar

# List all resources in the whole cluster in YAML format
kubectl really get all -o yaml

kubectl really delete all

Deletes absolutely all resources in a namespace, not just the ones that kubectl delete all deletes.

Example usage:

kubectl really delete all
kubectl really delete all -n some-namespace

kubectl ssh node

Provider-agnostic way of opening a remote shell to a Kubernetes node.

Enables you to access a node even when it doesn't run an SSH server or when you don't have the required credentials. Also, the way you log in is always the same, regardless of what provides the Kubernetes cluster (e.g. Minikube, Kind, Docker Desktop, GKE, AKS, EKS, ...)

You must have cluster-admin rights to use this plugin.

The primary focus of this plugin is to provide access to nodes, but it also provides a quick way of running a shell inside a pod.

Example usage:

kubectl ssh node             # access the node in a single-node cluster 
kubectl ssh node my-node     # access a node in a multi-node cluster

You can get your node name with the kubectl get nodes command.

You can also execute a command inside the node and quit like with command below:

kubectl ssh node my-node ls   # access a node in a multi-node cluster and execute ls

The kubectl ssh command runs the busybox image by default. You can override this by setting the KUBECTL_SSH_IMAGE environment variable.

export KUBECTL_SSH_IMAGE=alpine
kubectl ssh node my-node

Pull requests welcome

If anyone wants to help improve these plugins, please feel free to submit a pull request any time.

I don't have time to polish these plugins or create the krew metadata and submit them to the krew plugin repository. If you can do this, I and the rest of the Kubernetes community will be forever grateful!
