安装 Kubernetes

Kind

# For AMD64 / x86_64
[ $(uname -m) = x86_64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.23.0/kind-linux-amd64
# For ARM64
[ $(uname -m) = aarch64 ] && curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.23.0/kind-linux-arm64
chmod +x ./kind
sudo mv ./kind /usr/local/bin/kind

kind create cluster

https://kind.sigs.k8s.io/docs/user/quick-start/#interacting-with-your-cluster

kind create cluster --config - <<EOF
kind: Cluster

Multipass

multipass delete k8s-control-plane && multipass purge

multipass launch -c 8 -m 16g -d 64g -n k8s-control-plane --cloud-init cloud-init/k8s-control-plane.yaml -vvvv

multipass shell k8s-control-plane

/var/log/cloud-init.log
/var/log/cloud-init-output.log

omz plugin enable kubectl

在国内安装有可能遇到无法下载的问题，可以使用代理的方式安装，参考：
