## TL;DR
|
|
|
|
```sh
|
|
# Install minikube.
|
|
sudo pacman -S 'minikube'
|
|
brew install 'docker' 'minikube'
|
|
|
|
# Shell completion.
|
|
source <(minikube completion "$(basename $SHELL)")
|
|
|
|
# Disable emojis in the commands.
|
|
export MINIKUBE_IN_STYLE=false
|
|
|
|
# Start the cluster.
|
|
minikube start
|
|
minikube start --cpus '4' --memory '8192'
|
|
|
|
# Pause the cluster without impacting deployed applications
|
|
minikube pause
|
|
|
|
# Halt the cluster.
|
|
minikube stop
|
|
|
|
# Permanently increase the default memory limit.
|
|
# Requires the cluster to restart.
|
|
minikube config set 'memory' '16384'
|
|
|
|
# Browse the catalog of easily installable Kubernetes services.
|
|
minikube addons list
|
|
|
|
# Create a(nother) cluster running a specific Kubernetes version.
|
|
minikube start -p 'old-k8s' --kubernetes-version='v1.16.1'
|
|
minikube config set 'kubernetes-version' 'v1.16.15' && minikube start
|
|
|
|
# Use a specific docker driver.
|
|
minikube start --driver='docker'
|
|
minikube config set 'driver' 'docker' && minikube start
|
|
|
|
# Disable new update notifications.
|
|
minikube config set 'WantUpdateNotification' false
|
|
|
|
# Get IP and port of a service of type NodePort.
|
|
minikube service --url 'nextcloud'
|
|
minikube service --url 'nextcloud' --namespace 'nextcloud'
|
|
|
|
# Use the integrated kubectl command.
|
|
minikube kubectl -- get pods
|
|
|
|
# Log into the minikube environment (for debugging).
|
|
minikube ssh
|
|
|
|
# Delete all the clusters.
|
|
minikube delete --all --purge
|
|
```

|
## Troubleshooting
|
|
|
|
### What happens if one uses the _LoadBalancer_ type with Services
|
|
|
|
On cloud providers that support load balancers, an external IP address would be provisioned to access the Service; on minikube, the _LoadBalancer_ type makes the Service accessible through the `minikube service` command.
|
|
|
|
### Use custom certificates
|
|
|
|
Minikibe's certificates are available in the `~/.minikube/certs` folder.
