 This repository contains my personal set of notes, based on the video lecture series "Docker Containers and Kubernetes Fundamentals - Full Hands-On Course" from FreeCodeCamp.org [kTp5xUtcalw](https://www.youtube.com/watch?v=kTp5xUtcalw). My notes are mostly arranged to serve as cheat sheets for using Docker and Kubernetes. They are broken into the following pages:
 
 - [Docker Cheat Sheet](./docker_cheat_sheet.html)
+- [Kubernetes Cheat Sheet](./kubernetes_cheat_sheet.html)
 - [YAML Cheat Sheet](./yaml_cheat_sheet.html)

+# Kubernetes Cheat Sheet
+
+## kubectl CLI
+
+### Context
+
+|                                      |                             |
+|--------------------------------------|-----------------------------|
+|`kubectl config current-context`      |Get the current context      |
+|`kubectl config get-contexts`         |List all context             |
+|`kubectl config use-context [contextName]`|Set the current context  |
+|`kubectl config delete-context [contextName]`|Delete a context from the config file|
+
+### Misc.
+
+|                                      |                             |
+|--------------------------------------|-----------------------------|
+|`kubectl create -f [YAML file]`       |Create an object using YAML  |
+
+---
+
+### `kubectx`
+
+- Separate program that acts as an alias for `kubectl config use-context`
+    - *Fast way to switch between clusters and namespaces in kubectl*
+
+---
+
+### Declarative vs Imperative
+
+#### Declarative Example - YAML File
+
+```yaml
+apiVersion: v1
+kind: Pod
+metadata:
+  name: myapp-pod
+  labels:
+    app: myapp
+    type: front-end
+spec:
+  containers:
+    name: nginx-container
+    image: nginx
+```
+
+#### Imperative Example - Series of commands
+
+```sh
+kubectl run mynginx --image=nginx --port=80
+
+kubectl create deploy mynginx --image=nginx --port=80 --replicas=3
+
+kubectl create service nodeport myservice --targetPort=8080
+
+kubectl delete pod nginx
+```
+
+### YAML required properties
+
+- Root level required properties
+    - `apiVersion`
+        - Api version of the object
+    - `kind`
+        - type of object
+    - `metadata.name`
+        - unique name for the object
+    - `metadata.namespace`
+        - scoped environment name (will default to current)
+    - `spec`
+        - object specifications or desired state
