docker 安裝 卸載 Kubernetes安裝

一般情況都會先學docker，然后再學Kubernetes。所有會先安裝docker，然后就是安裝Kubernetes。然后Kubernetes中包含了docker。安裝會報錯

1.docker安裝

依賴包

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

docker軟件包

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

安裝

yum install docker-ce 

啟動與停止

systemctl start docker
systemctl stop docker
systemctl enbale docker

 

查詢安裝情況

yum list installed | grep docker
containerd.io.x86_64 1.2.4-3.1.el7 @docker-ce-edge
docker-ce-cli.x86_64 1:18.09.3-3.el7 @docker-ce-edge

卸載

yum -y remove docker-ce-cli.x86_64
yum -y remove containerd.io.x86_64

刪除鏡像/容器等

rm -rf /var/lib/docker
rm -rf /var/run/docker

安裝kubernetes

yum install -y etcd kubernetes
