序

之前使用multipass裝ubuntu，然后再用microk8s搭建k8s，這會直接用orbstack及kind在本地搭建k8s及istio

安裝

orbstack

通過orbstack這個地址下載，主要是開銷低，用來替代docker desktop

添加國內(nèi)源
~/.orbstack/config/docker.json

{
	"registry-mirrors": [
        "http://hub-mirror.c.163.com",
        "https://docker.mirrors.ustc.edu.cn",
        "https://registry.docker-cn.com",
        "https://registry.hub.docker.com"
    ]
}

重啟orbstack

安裝go

brew install go
go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direct

安裝kind

go install sigs.k8s.io/kind@v0.20.0
export PATH=$HOME/go/bin:$PATH
kind create cluster
Creating cluster "kind" ...

Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

Have a nice day! ??

使用

kubectl cluster-info --context kind-kind
Kubernetes control plane is running at https://127.0.0.1:51562
CoreDNS is running at https://127.0.0.1:51562/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

kubectl get pods -A

安裝istio

curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.2.5 sh -

或者下載https://github.com/istio/istio/releases/download/1.18.2/istio-1.18.2-osx-arm64.tar.gz
解壓，并將istio-1.18.2/bin添加到PATH中

istioctl install --set profile=demo -y

? Istiod installed

小結(jié)

使用orbstack及kind在本地搭建k8s及istio顯得極為輕量，首先orbstack比multipass起個machine輕量許多，其次kind比k3s，minikube更為輕量，雖然是單節(jié)點(diǎn)，但是特別適合學(xué)習(xí)和研究。文章來源地址http://www.zghlxwxcb.cn/news/detail-621750.html
