Kubernetes 是一个开源系统，用于容器化应用的自动部署、扩缩和管理。它将构成应用的容器按逻辑单位进行分组以便于管理和发现。

配置镜像源

Debian / Ubuntu

apt-get update && apt-get install -y apt-transport-https curl https://mirrors.aliyun.com/kubernetes/apt/doc/apt-key.gpg | apt-key add - cat <<EOF >/etc/apt/sources.list.d/kubernetes.list deb https://mirrors.aliyun.com/kubernetes/apt/ kubernetes-xenial main EOF apt-get update

CentOS / RHEL / Fedora

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 setenforce 0

1.安装：按照顺序

yum install kubelet-1.13.12-0 yum install kubectl-1.13.12-0 yum install kubeadm-1.13.12-0

2.安装后执行如下命令，，先查看需要的镜像文件：

kubeadm config images list ----------------------------- k8s.gcr.io/kube-apiserver:v1.13.12 k8s.gcr.io/kube-controller-manager:v1.13.12 k8s.gcr.io/kube-scheduler:v1.13.12 k8s.gcr.io/kube-proxy:v1.13.12 k8s.gcr.io/pause:3.1 k8s.gcr.io/etcd:3.2.24 k8s.gcr.io/coredns:1.2.6

3.导入并配置对应的镜像文件

docker load -i registry.aliyuncs.com.google_containers.kube-apiserver.tar docker image ls tag f07fae2c3e6a k8s.gcr.io/kube-apiserver:v1.13.12 docker load -i registry.aliyuncs.com.google_containers.kube-controller-manager.tar docker image ls docker tag 90fd4a237264 k8s.gcr.io/kube-controller-manager:v1.13.12 docker load -i registry.aliyuncs.com.google_containers.kube-scheduler.tar docker image ls docker tag 54f3185a42a5 k8s.gcr.io/kube-scheduler:v1.13.12 docker load -i registry.aliyuncs.com.google_containers.kube-proxy.tar docker image ls docker tag 4022daa30d3e k8s.gcr.io/kube-proxy:v1.13.12 docker load -i registry.aliyuncs.com.google_containers.pause.tar docker image ls docker tag da86e6ba6ca1 k8s.gcr.io/pause:3.1 docker load -i registry.aliyuncs.com.google_containers.etcd.tar docker image ls docker tag 3cab8e1b9802 k8s.gcr.io/etcd:3.2.24 docker load -i registry.aliyuncs.com.google_containers.coredns.tar docker image ls docker tag f59dcacceff4 k8s.gcr.io/coredns:1.2.6

4.导入并修改好镜像名后执行

kubeadm init --pod-network-cidr=10.244.0.0/16

5.若出现报错

6.执行如下命令

kubeadm init --pod-network-cidr=10.244.0.0/16 --ignore-preflight-errors=swap

7.执行后若出现报错：

8.需要查看日志：

journalctl --no-page -xeu kubelet
--或者 journalctl --no-page -xeu kubelet|grep swap

9.查看配置文件：

cd /usr/lib/systemd/system/kubelet.service.d [[email protected] kubelet.service.d]# ls 10-kubeadm.conf

10.找出配置文件中环境配置文件路径

EnvironmentFile=-/etc/sysconfig/kubelet

11.修改环境配置文件：

KUBELET_EXTRA_ARGS="--fail-swap-on=false"

12.重启kubeadm

kubeadm reset

13.再次执行

kubeadm init --pod-network-cidr=10.244.0.0/16 --ignore-preflight-errors=swap

14.环境搭建成功
