Kubernetes time-saving aliases

When preparing for Kubernetes certifications like the CKA or CKAD, saving time during the exam is crucial. One of the best ways to be efficient is by setting up terminal aliases for common kubectl commands. Here is a handy list of time-saving aliases you can use.

General Aliases

These are your standard shortcuts for everyday commands.

alias k='kubectl' # Base command shortcut
alias ks='kubectl -n kube-system' # Execute command in the kube-system namespace
alias kdesc='kubectl describe' # Describe a specific resource

Create Resources

Use these aliases when creating or applying new resources to your cluster from YAML files.

alias kcf='kubectl create -f' # Create a resource from a file or stdin
alias kaf='kubectl apply -f' # Apply a configuration to a resource by filename or stdin

Get Resources

Viewing the status of your cluster is something you will do constantly. Here are some quick commands to fetch pods, nodes, and more.

alias kgn='kubectl get nodes' # List all nodes in the cluster
alias kgp='kubectl get pods' # List all pods in the current namespace
alias kgpa='kubectl get pods --all-namespaces' # List all pods across all namespaces
alias kgs='kubectl get services' # List all services in the current namespace
alias kgd='kubectl get deployments' # List all deployments in the current namespace

Delete Resources

When tearing down resources or cleaning up, use these helpful delete aliases to speed up the process.

alias kd='kubectl delete' # Delete a resource by filename, stdin, resource and name
alias kdp='kubectl delete pod' # Delete a specific pod
alias kds='kubectl delete service' # Delete a specific service
alias kdd='kubectl delete deployment' # Delete a specific deployment
alias kdn='kubectl delete namespace' # Delete a specific namespace

Setting up these aliases at the very beginning of your session can save you valuable minutes and eliminate repetitive typing during your certification exams!
