Kind

Kind = Kubernetes in Docker，简单说就是把k8s run在docker上面，少了安装在本机上面的动作，
Kind也是个Kubernetes SIGs project，跟常用的minikube对比，把原本安装在vm上面改到container上面

手把手安装

安装前请先安装好go与docker

1.安装kind

GO111MODULE="on" go get sigs.k8s.io/[email protected]

执行结果

go: downloading sigs.k8s.io/kind v0.11.1
go: downloading github.com/spf13/cobra v1.1.1
go: downloading github.com/alessio/shellescape v1.4.1
go: downloading k8s.io/apimachinery v0.20.2
go: downloading golang.org/x/sys v0.0.0-20210124154548-22da62e12c0c
go: downloading sigs.k8s.io/yaml v1.2.0
go: downloading github.com/evanphx/json-patch v4.9.0+incompatible
go: downloading github.com/pelletier/go-toml v1.8.1
go: downloading github.com/inconshreveable/mousetrap v1.0.0
go: downloading github.com/evanphx/json-patch/v5 v5.2.0

2.新增cluster

kind create cluster

执行结果

Creating cluster "kind" ...
 ✓ Ensuring node image (kindest/node:v1.21.1) ?
 ✓ Preparing nodes ?
 ✓ Writing configuration ?
 ✓ Starting control-plane ?️
 ✓ Installing CNI ?
 ✓ Installing StorageClass ?
Set kubectl context to "kind-kind"
You can now use your cluster with:

kubectl cluster-info --context kind-kind

Thanks for using kind! ?

也是可以使用参数指定cluster的名称

kind create cluster --name test-kind-cluster

需要指定node image版本，可以加上tag

kind create cluster --name tag-version-kind --image kindest/node:v1.21.1

安装仪表版

kind不像minikube有自带仪表版，所以需要自行安装
1.安装dashboard

kubectl apply -f https://raw.githubusercontent.com/kubernetes/dashboard/v2.0.0-beta8/aio/deploy/recommended.yaml

确认一下有没有正常运作

kubectl get pod -n kubernetes-dashboard

执行结果

NAME                                         READY   STATUS    RESTARTS   AGE
dashboard-metrics-scraper-778b77d469-v85pw   1/1     Running   0          3m5s
kubernetes-dashboard-5cd89984f5-9vtsm        1/1     Running   0          3m5s

2.安装ClusterRoleBinding，提供刚刚建的cluster管理权限存取

kubectl create clusterrolebinding default-admin --clusterrole cluster-admin --serviceaccount=default:default

3.因为仪表板是使用token登入，所以把token汇出

token=$(kubectl get secrets -o jsonpath="{.items[?(@.metadata.annotations['kubernetes\.io/service-account\.name']=='default')].data.token}"|base64 -d)

echo $token

4.使用kubectl proxy进入仪板表

kubectl proxy

5.登入

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#/login

6.填入token就可以看到k8s资讯啦

kind的基础安装就到这边了
