Summary - Minikube

Combine start, status and dashboard to set up a cluster.

Summary: Minikube

In this group:

Minikube runs a Kubernetes cluster locally; kind and k3d are similar tools.
minikube start (--driver, --cpus, --memory, --nodes, -p), stop and delete manage the cluster life cycle.
Local images are used via minikube image load or docker-env.
addons enable installs components such as metrics-server, ingress and dashboard.
status, ip, service --url and dashboard --url are for access and status.

minikube start --driver=docker --cpus=4 --memory=8g
minikube addons enable metrics-server
minikube image load api:1.0

Exercise A clean start

Write four commands: delete the existing Minikube cluster; start again with the Docker driver, 2 CPUs and 4g memory; enable the metrics-server add-on; show the status.

Show example solution

minikube delete
minikube start --driver=docker --cpus=2 --memory=4g
minikube addons enable metrics-server
minikube status

Test yourself

If a pod created with a locally built image gives ErrImagePull, what is the likely cause?
- The image wasn't loaded into the cluster and it's being pulled from a registry
- The port is wrong
- Minikube has stopped
- YAML indentation
Show answer

The image wasn't loaded into the cluster and it's being pulled from a registry — minikube image load and imagePullPolicy: IfNotPresent are the fix.
Stop the cluster but don't delete it.
