1、查看安装过的docker：

dockerlist=`yum list installed | grep docker`

dlength=${#dockerlist $@$ }

ditem=${dockerlist $0$ }

2、卸载docker：

#for loop

for ditem in ${dockerlist $@$ }

echo `yum remove -y ${ditem}`

echo "remove $ditem success"

done

3、删除容器镜像：

rm -rf /var/lib/docker

echo "remove docker success"

安装Docker-cker-CE

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

增加最新版本的Docker安装仓库

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

安装Docker-CE版本

yum -y install docker-ce

启动docker

systemctl enable docker

允许开机启动

systemctl start docker

mkdir -p /etc/docker

tee /etc/docker/daemon.json <<-'EOF'

{

"registry-mirrors": $"https://6csf38x3.mirror.aliyuncs.com"$

}

EOF

重启docker

systemctl daemon-reload

systemctl restart docker

jar包通过dockerfile打docker镜像

docker build -f ./Dockerfile -t dcxt .

运行刚才打包的镜像

docker run --name dcxt -u root -d -p 9021:9021 dcxt
