下载安装包

sudo wget https://github.com/kubesphere/kubekey/releases/download/v1.1.0/kubekey-v1.1.0-linux-64bit.deb

使用 cilium 作为网络插件部署 KubeSphere

1.安装 KubeKey

sudo dpkg -i kubekey-v1.1.0-linux-64bit.deb

2.生成配置文件

sudo kk create config --with-kubernetes v1.19.8

3.修改配置文件，将网络插件修改为 cilium
注意将spec.network.plugin 的值修改为 cilium

sudo vi config-sample.yaml

apiVersion: kubekey.kubesphere.io/v1alpha1
kind: Cluster
metadata:
  name: sample
spec:
  hosts:
  - {name: node1, address: 10.160.6.136, internalAddress: 10.160.6.136, user: ubuntu, password: ********}
  roleGroups:
    etcd:
    - node1
    master: 
    - node1
    worker:
    - node1
  controlPlaneEndpoint:
    domain: lb.kubesphere.local
    address: ""
    port: 6443
  kubernetes:
    version: v1.19.8
    imageRepo: kubesphere
    clusterName: cluster.local
  network:
    plugin: cilium
    kubePodsCIDR: 10.233.64.0/18
    kubeServiceCIDR: 10.233.0.0/18
  registry:
    registryMirrors: []
    insecureRegistries: []
  addons: []

4.部署依赖

sudo kk init os -f config-sample.yaml

5.部署 KubeSphere

sudo kk create cluster -f config-sample.yaml --with-kubesphere v3.1.0

7.检查状态

安装hubble UI

kubectl apply -f https://raw.githubusercontent.com/cilium/cilium/v1.8/install/kubernetes/experimental-install.yaml

检查状态

安装 demo 服务，并在 hubble UI 查看服务依赖关系

1.安装 demo

kubectl apply -f https://raw.githubusercontent.com/cilium/cilium/1.9.7/examples/minikube/http-sw-app.yaml -n default

2.将 hubble UI 服务类型修改为 nodeport

kubectl exec xwing -n default -- curl -s -XPOST deathstar.default.svc.cluster.local/v1/request-landing
Ship landed
kubectl exec tiefighter -n default -- curl -s -XPOST deathstar.default.svc.cluster.local/v1/request-landing
Ship landed

4.在 hubble 上查看服务依赖关系
