需求

安装kubernetes - minikube本地环境

准备条件

  1. 一台vps(本文使用阿里云香港 - centos7.7)- 用国内的服务器折腾的好一会儿都被墙了,先不把时间浪费在这,直接上香港的服务器
  2. 一台能ssh连接到vps的本地电脑 (推荐连接工具xshell)

安装步骤

在安装前需要配置国内的镜像源

cat <<eof > /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=kubernetes
baseurl=https://mirrors.aliyun.com/kubernetes/yum/repos/kubernetes-el7-x86_64/
enabled=1
gpgcheck=1
repo_gpgcheck=1
gpgkey=https://mirrors.aliyun.com/kubernetes/yum/doc/yum-key.gpg https://mirrors.aliyun.com/kubernetes/yum/doc/rpm-package-key.gpg
eof

安装kubectl

yum install -y kubectl

shell 中开启 kubectl 命令自动补全

yum install bash-completion -y
echo "source <(kubectl completion bash)" >> ~/.bashrc

安装minukube

curl -lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64 \
  && chmod +x minikube
mkdir -p /usr/local/bin/
install minikube /usr/local/bin/
su - docker

启动本地 kubernetes 集群、 检查集群的状态

minikube start

* minikube v1.9.2 on centos 7.7.1908
* automatically selected the docker driver
* starting control plane node m01 in cluster minikube
* pulling base image ...
* downloading kubernetes v1.18.0 preload ...
    > preloaded-images-k8s-v2-v1.18.0-docker-overlay2-amd64.tar.lz4: 542.91 mib
* creating kubernetes in docker container with (cpus=2) (4 available), memory=2200mb (7821mb available) ...
* preparing kubernetes v1.18.0 on docker 19.03.2 ...
  - kubeadm.pod-network-cidr=10.244.0.0/16
* enabling addons: default-storageclass, storage-provisioner
! enabling 'default-storageclass' returned an error: running callbacks: [chmod: chmod deploy/addons/storageclass/storageclass.yaml.tmpl: permission denied]
* done! kubectl is now configured to use "minikube"

minikube status

m01
host: running
kubelet: running
apiserver: running
kubeconfig: configured
kubectl cluster-info

kubernetes master is running at https://172.17.0.2:8443
kubedns is running at https://172.17.0.2:8443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

to further debug and diagnose cluster problems, use 'kubectl cluster-info dump'.

开启kubernetes dashboard服务

minikube dashboard --url

* enabling dashboard ...
* verifying dashboard health ...
* launching proxy ...
* verifying proxy health ...
http://127.0.0.1:33457/api/v1/namespaces/kubernetes-dashboard/services/http:kubernetes-dashboard:/proxy/

开启kube-proxy端口映射,使其可以远程访问

kubectl proxy --port=33458 --address='0.0.0.0' --accept-hosts='^.*' &

这里需要记得去阿里云的安全组配置33458端口外网可以访问

然后就可以在浏览器访问k8s的dashborad了


Minikube 安装

清理 minikube 的本地状态

minikube delete
