== Install Minikube ==
Mac:

<syntaxhighlight lang="bash">
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-darwin-arm64
sudo install minikube-darwin-arm64 /usr/local/bin/minikube

</syntaxhighlight>

Ubuntu:
<syntaxhighlight lang="bash">
curl -LO https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo install minikube-linux-amd64 /usr/local/bin/minikube
minikube config set rootless true
</syntaxhighlight>

== Start Minikube ==
If use docker:

<syntaxhighlight lang="bash">
# Ubuntu:
# sudo usermod -aG docker $USER && newgrp docker
minikube start --cpus=4 --memory=4096 --addons=ingress --kubernetes-version=1.29.2
</syntaxhighlight>

For podman(does not work):
<syntaxhighlight lang="bash">
sudo chmod +w /etc/sudoers
# add this line to the END of the file
riguz ALL=(ALL) NOPASSWD: ALL 

sudo chmod -w /etc/sudoers
# To test:
# sudo -n -k podman version

minikube start --cpus=4 --memory=4096 --addons=ingress --container-runtime=containerd
</syntaxhighlight>

Install Kubectl(Ubuntu):

<syntaxhighlight lang="bash">
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

A registry for function images is required. For example, 'docker.io/tigerteam'.
? Registry for function images: localhost:5000/helloworld
Note: building a function the first time will take longer than subsequent builds
   🙌 Function built: localhost:5000/helloworld/helloworld:latest
$ func deploy
function up-to-date. Force rebuild with --build
   ✅ Function deployed in namespace "default" and exposed at URL:
   http://helloworld.default.127.0.0.1.sslip.io

== Access from host network==

<syntaxhighlight lang="bash">
kubectl port-forward --namespace kourier-system service/kourier 8080:80 --address 0.0.0.0
sudo ufw enable 8080

Then， access the service:
