I made a Kubernetes Cheat Sheet: I was tired of looking up all the Kubernetes commands

Kubernetes Cheatsheet

Have you ever found yourself wasting twenty minutes trying to find the right command to complete a task while working on a Kubernetes project? I certainly have. I’ve been working on several Kubernetes projects lately, and I found remembering all the necessary commands challenging.

To solve this problem, I created a database of commands that would help me analyze the cluster and complete different tasks quickly. This way, I don’t have to memorize everything, and I can always access my documentation whenever needed.

Since I believe many people might benefit from such a database, I decided to share it with others. I will keep updating it as I learn more and complete different tasks.

To make it easy to use, I’ve organized the commands based on the tasks they accomplish. Here are the commands:

Create Resources

• Kubectl run … : creates a pod
• Kubectl create … : reates a deployment, service, replicasets, or other resources
• Kubectl create -h : get help on using the create command
• Kubectl run -h : Get help on using the run command
• Kubectl apply -f : create a resource from a definition file

View Resources

• Kubectl get : list a resource in the current namespace
• Kubectl get -o wide : list the specified resource with more details
• Kubectl get — -all-namespaces and Kubectl get -A : lists all the specified resources in all the namespaces
• Kubectl get -n : lists all the specified resources in a specified namespace
• Kubectl get -o yaml > : get a resource in a definition file format
• Kubectl get -l = : Lists all the resources with the specified label
• Kubectl describe : View detailed information about a resource

Delete Resources

• Kubectl delete : deletes a Kubernetes resource
• Kubectl delete : delete multiple resources
• Kubectl delete -all : deletes all of the specified resource types
• Kubectl delete -n : Delete all specified resources in a specific namespace
• Kubectl delete — -all -n : Delete all specified resources in a specific namespace
