I’m just amazed of how well Josh Long explains and demos concepts

minikube in 1 min
minikube is a Kubernetes Cluster SetUp,
minikube is a tool that lets you run Kubernetes locally, it runs a single-node Kubernetes cluster on your personal computer.
Think of minikube as a service.
You need to start and stop it when you want to use it in a development context. We started minikube earlier by running:minikube start / minikube stop
- Starting the cluster configures a k8s “context” within
~/.kube/config.
This entry defines the way in which kubectl will communicate with a cluster. - It’s a good idea to get into the habit of stopping your local cluster when not in use, as it will eat your system resources when idle.

I really recommend this Kubernetes Crash Course for Absolute Beginners on YouTube
Simple Dev-Ops
The best explanation for me(so far) about DevOps
Ops – it operates the application in production
That is, it assure service uptime and availability(responsiveness)
### Deploy to produciton
### Monitoring (for service uptime/availability)
– if the service is down, it will restart it
– if the machine/server is going crazy(if there is high load, no disk space, etc..), it will alert, intervene, solve, investigate
– if the application throws a lot (of unexpected) errors/exceptions
### Service responsiveness
– scaling, add a new node
