## resources on kubernetes

<br>

### tl; dr

<br>

1. a **kubernetes cluster** consists of nodes (similar to servers) 
2. **nodes** run **pods**, which are collections of **docker containers**
3. **containers** in a pod share the same network
4. **deployment** is a kubernetes object responsible for launching and maintaining pods
6. **services** objects allow pods to communicate with other pods

##### tools


- [Minikube](https://github.com/kubernetes/minikube) implements a local Kubernetes cluster on macOS, Linux, and Windows. You can install it following [this instructions](https://minikube.sigs.k8s.io/docs/start/).
- [kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/) is a command line interface for running commands against Kubernetes clusters.
- [kubectx](https://github.com/ahmetb/kubectx) is a tool to switch between k8s contexts.
- [k14s](https://k14s.io/): Kubernetes Tools that follow Unix philosophy to be simple, and composable.
