Docker 安装

Install Docker CE

Set up the repository

sudo apt-get update
sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    software-properties-common
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add -
sudo apt-key fingerprint 0EBFCD88
sudo add-apt-repository \
   "deb [arch=amd64] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) \
   stable"

Install Docker CE

sudo apt-get update
sudo apt-get install docker-ce
sudo docker run hello-world

Configure Docker to start on boot

$ sudo systemctl enable docker

Install docker-compose on Linux systems：

安装

sudo curl -L "https://github.com/docker/compose/releases/download/1.24.1/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

or

pip install docker-compose

添加可执行权限

sudo chmod +x /usr/local/bin/docker-compose

测试

docker-compose --version

docker-compose开机启动

在 docker-compose.yml 中加入

restart: always
比如:
 restart: always
        volumes:
            - "./nginx.conf:/etc/nginx/nginx.conf:ro"

当系统重启后，docker daemon重启会自动运行容器，前提是docker-compose要成功的运行一次。
镜像加速:

sudo nano /etc/docker/daemon.json
{
 "registry-mirrors": ["https://bjtzu1jb.mirror.aliyuncs.com"]
}
