申明：本文参考博客安装单机版kubernetes_帅凡x的博客-CSDN博客​​​​​​​安装单机版kuberneteshttps://blog.csdn.net/qq_42244644/article/details/124406032

准备系统：vmware下的centos7虚拟机

安装步骤：

1.首先关闭防火墙和selinux

修改文件vi /etc/selinux/config

2. 禁用swap

 

3. 修改内核参数和模块

修改文件vi /etc/sysctl.d/k8s.conf

执行命令

4. 安装docker

yum -y install yum-utils device-mapper-persistent-data lvm2

yum-config-manager -y --add-repo https://download.docker.com/linux/centos/docker-ce.repo

yum -y install docker-ce-18.06.3.ce-3.el7 docker-ce-cli-18.06.3.ce-3.el7 containerd.io

systemctl start docker

systemctl enable docker

安装完执行下docker version

5. 安装kubernates组件

修改文件vi /etc/yum.repos.d/kubernetes.repo

执行命令

yum -y install kubelet-1.13* kubeadm-1.13* kubectl-1.13*

systemctl start kubelet

systemctl enable kubelet

6. 下载kubernetes镜像

docker pull mirrorgooglecontainers/kube-apiserver:v1.13.3

docker pull mirrorgooglecontainers/kube-controller-manager:v1.13.3

docker pull mirrorgooglecontainers/kube-scheduler:v1.13.3

docker pull mirrorgooglecontainers/kube-proxy:v1.13.3

docker pull mirrorgooglecontainers/pause:3.1

docker pull mirrorgooglecontainers/etcd:3.2.24

docker pull coredns/coredns:1.2.6
 
# 打标签
docker tag mirrorgooglecontainers/kube-apiserver:v1.13.3 k8s.gcr.io/kube-apiserver:v1.13.3

docker tag mirrorgooglecontainers/kube-controller-manager:v1.13.3 k8s.gcr.io/kube-controller-manager:v1.13.3

docker tag mirrorgooglecontainers/kube-scheduler:v1.13.3 k8s.gcr.io/kube-scheduler:v1.13.3

docker tag mirrorgooglecontainers/kube-proxy:v1.13.3 k8s.gcr.io/kube-proxy:v1.13.3

docker tag mirrorgooglecontainers/pause:3.1 k8s.gcr.io/pause:3.1

docker tag mirrorgooglecontainers/etcd:3.2.24 k8s.gcr.io/etcd:3.2.24

docker tag coredns/coredns:1.2.6 k8s.gcr.io/coredns:1.2.6

7. 初始化

kubeadm init --kubernetes-version=v1.13.3 --pod-network-cidr=10.100.0.0/16

 

接下来根据提示做如下操作

mkdir -p $HOME/.kube
sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
sudo chown $(id -u):$(id -g) $HOME/.kube/config
kubectl apply -f https://cloud.weave.works/k8s/net?k8s-version=$(kubectl version | base64 | tr -d '\n')

成功后执行如下命令看是否成功

kubectl get pods --all-namespaces

至此安装完成
