docker安装部署

系统 centos
uname -a
uname -r
cat /etc/redhat-release   #查看操作系统版本
ls -l /sys/class/misc/device-mapper/

centos命令

yum包更新到最新

sudo yum update -y
安装需要的软件包、yum-util提供yum-config-manager功能  
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

设置yum源为阿里云

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

安装docker

sudo yum install docker-ce -y
docker -v 查看版本

配置docker镜像加速器

mkdir /etc/docker
vi /etc/docker/daemon.json
{
    "registry-mirrors": [
        "https://wa0xneb0.mirror.aliyuncs.com",
        "http://hub-mirror.c.163.com",
        "https://mirrors.tuna.tsinghua.edu.cn",
        "http://mirrors.sohu.com",
        "https://ustc-edu-cn.mirror.aliyuncs.com",
        "https://ccr.ccs.tencentyun.com",
        "https://docker.m.daocloud.io",
        "https://docker.awsl9527.cn"
    ]
}
sudo systemctl daemon-reload
sudo systemctl restart docker

注意：阿里云镜像 需要登录阿里云账号，获取对应的阿里云镜像加速器，每个账号不一样

国内镜像无法访问问题使用下面替换

https://1ms.run/

启动docker和相关状态查询命令

systemctl start docker
systemctl stop docker
systemctl restart docker
systemctl status docker

系统默认开机启动

systemctl enable docker
docker info

网卡转发

sysctl -a | grep -w net.ipv4.ip_forward 响应为1正常
否则，执行下面
cat <<EOF> /etc/sysctl.d/docker.conf
net.bridge.bridge-nf-call-ip6tables=1
net.bridge.bridge-nf-call-iptables=1
net.ipv4.ip_forward=1
EOF
sysctl -p /etc/sysctl.d/docker.conf

Ubuntu命令

包更新到最新

sudo apt update -y

安装必要依赖

sudo apt install -y apt-transport-https ca-certificates curl gnupg lsb-release

安装docker

如下两种操作容易失败

如果失败需要先卸载

sudo rm -f /usr/share/keyrings/docker-archive-keyring.gpg

第一种方式

sudo rm -f /usr/share/keyrings/docker-archive-keyring.gpg
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

第二种方式

sudo rm -f /etc/apt/sources.list.d/docker.list
curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://mirrors.aliyun.com/docker-ce/linux/ubuntu focal stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
cat /etc/apt/sources.list.d/docker.list

sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin

配置 Docker Hub 镜像加速器

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": [
    "https://docker.xuanyuan.me",
    "https://docker.1ms.run",
    "https://docker.m.daocloud.io"
  ]
}
EOF

重启 Docker 服务并验证配置

sudo systemctl daemon-reload
sudo systemctl restart docker

验证是否正常

sudo docker run hello-world
