一、安装Docker
Docker部署Jenkins前提已经安装Docker，这边脚本安装Docker。
[root@ip-10-0-12-212 ~]
#!/usr/bin/bash
source /etc/init.d/functions
rely_software=(yum-utils device-mapper-persistent-data lvm2)
echo "-----------------#1.检测系统内核版本-----------------"
kernel_version=`uname -a |awk '{print $3}'|cut -d. -f1`
[ $kernel_version -ge 3 ] && action "The System Install Docker is ..." /usr/bin/true || action "The System Can not Install Docker is ...";exit
echo "-----------------#2.安装Docker依赖软件-----------------"
for i in ${rely_software[*]}
do
rpm -q $i &>/dev/null
if [ $? -eq 0 ];then
echo "$i is installed"
else
yum -y install $i &>/dev/null
action "$i is installing" /usr/bin/true
fi
done
echo "-----------------#3.添加Docker镜像源-----------------"
yum-config-manager --add-repo //mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
[ $? -eq 0 ] && action "Docker Image add is ..." /usr/bin/true || echo "Docker Image add is ..." /usr/bin/false;exit
echo "-----------------#4.安装Docker-----------------"
yum -y install docker-ce
rpm -qa |grep docker-ce
[ $? -eq 0 ] && action "Docker-ce is installed ..." /usr/bin/true || action "Docker-ce is install ..." /usr/bin/false;exit
echo "-----------------#5.启动Docker并设置开机自启-----------------"
systemctl enable --now docker
[ $? -eq 0 ] && action "Docker Start is ...;" /usr/bin/true || action "Docker start is ..." /usr/bin/false
docker_version=`docker -v |awk -F ',' '{print $1}'`
echo "-----------------#6.设置Docker加速器-----------------"
sudo mkdir -p /etc/docker
sudo cat >/etc/docker/daemon.json <<EOF
{
"registry-mirrors": ["//8mh75mhz.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
echo "-----------------#7.查看Docker是否安装完成-----------------"
cat << EOF
+-------------------------------------------------+
| $docker_version 安 装 已 完 成 |
| 请 使 用 相 关 服 务 ! |
+-------------------------------------------------+
EOF
echo "-----------------#8.迁移Docker根目录-----------------"
systemctl stop docker
mv /var/lib/docker/ /data/
sed -i 's#ExecStart=/usr/bin/dockerd#ExecStart=/usr/bin/dockerd --graph=/data/docker#g' /usr/lib/systemd/system/docker.service
systemctl daemon-reload
systemctl start docker.service
echo "-----------------#9.验证Docker根目录是否生效-----------------"
docker info |grep "Docker Root Dir"
sleep 5
echo ""-----------------你的小可爱已完成Docker全部部署-----------------"

二、编写Dockerfile
[root@ip-10-0-12-212 ~]
[root@ip-10-0-12-212 ~]
[root@ip-10-0-12-212 jenkins]

三、构建Dockerfile
[root@ip-10-0-12-212 jenkins]
... ...
Successfully built 1e2736247512
Successfully tagged datalake_jenkins:v1
四、运行Docker容器
[root@ip-10-0-12-212 jenkins]
