Ubuntu18配置Docker

1.基本过程

1.更新软件源列表

复制代码

sudo apt update

2.安装软件包依赖

复制代码

sudo apt install apt-transport-https ca-certificates curl software-properties-common

3.在系统中添加Docker的官方密钥

复制代码

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
4.添加Docker源,选择stable长期稳定版

sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu bionic stable"

5.再次更新源列表

复制代码

sudo apt update

6.查看可以安装的Docker版本

复制代码

sudo apt-cache policy docker-ce

7.开始安装Docker

++这里以20.10版本为例++

复制代码

sudo apt-get install -y docker-ce=5:20.10.10~3-0~ubuntu-bionic docker-ce-cli=5:20.10.10~3-0~ubuntu-bionic containerd.io
9.查看安装的Docker版本

10.启动Docker服务

shell 复制代码

sudo systemctl start docker

11.设置开机自启动docker

复制代码

sudo systemctl enable docker

2.镜像加速设置

shell 复制代码

sudo systemctl start docker
sudo systemctl enable docker
sudo systemctl status docker

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
  "registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"],
  "exec-opts": ["native.cgroupdriver=systemd"],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "100m"
  },
  "storage-driver": "overlay2"
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker

查看是否配置成功

复制代码

docker info

3.Docker-compose安装

复制代码

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose
docker-compose --version
