正式环境 - Docker部署文档

1、安装
1.1、安装文档

https://docs.docker.com/install/linux/docker-ce/binaries/

1.2、二进制安装下载路径

https://download.docker.com/linux/
https://mirrors.aliyun.com/docker-ce/linux/static/stable/x86_64/

1.3、下载二进制文件

wget https://mirrors.aliyun.com/docker-ce/linux/static/stable/x86_64/docker-20.10.9.tgz

1.4、解压二进制文件

tar zxvf docker-20.10.9.tgz

1.5、复制二进制文件

cp docker/* /usr/bin/

1.6、检查是否安装

docker version

1.7、配置 docker.service文件

vi /usr/lib/systemd/system/docker.service
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target
[Service]
Type=notify
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi-user.target

1.8、启动dockerd服务进程

systemctl daemon-reload
systemctl start docker.service

1.9、检验

ps aux|grep docker
docker run hello-world

1.10、设置开机启动

systemctl enable nginx.service
#systemctl start nginx.service
#systemctl stop nginx.service
#systemctl enable nginx.service
#systemctl disable nginx.service
#systemctl status nginx.service
#systemctl restart nginx.service
#systemctl list-units --type=service  #

2、配置镜像加速器
//针对Docker客户端版本大于 1.10.0 的用户 您可以通过修改daemon配置文件/etc/docker/daemon.json来使用加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://un1tt4qx.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

3、更改docker的数据目录

sudo mkdir -p /usr/local/docker-data/docker
sudo cp -ar /var/lib/docker/ /usr/local/docker-data/docker
sudo vim  /etc/docker/daemon.json
{
"registry-mirrors": ["https://un1tt4qx.mirror.aliyuncs.com"],
"graph":"/usr/local/docker-data/docker"
}
sudo systemctl daemon-reload
sudo systemctl restart docker
