Ubuntu18配置Docker

1.基本过程

1.更新软件源列表

sudo apt update

2.安装软件包依赖

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

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

sudo apt update

6.查看可以安装的Docker版本

sudo apt-cache policy docker-ce

7.开始安装Docker

这里以20.10版本为例

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

sudo systemctl start docker

11.设置开机自启动docker

sudo systemctl enable docker

2.镜像加速设置

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

docker info

3.Docker-compose安装

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
