docker引擎安装

高版本docker引擎安装时已经自带有docker compose 安装参考docker官网Install Docker Engine on Ubuntu

方式一： 在线安装

参考apt方式安装

1、Set up Docker’s apt repository.

# Add Docker's official GPG key:
sudo apt-get update
sudo apt-get install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update

2、Install the Docker packages.

sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

方式二： 离线安装

deb离线安装包资源链接

## 解压后执行安装相关依赖
sudo dpkg -i ./*.deb -y

容器日志保留策略设置

修改后需重启docker引擎

sudo bash -c 'cat <<EOF >>/etc/docker/daemon.json
{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "10m",
    "max-file": "5"
  }
}
EOF
'
sudo systemctl restart docker

其他常用命令

## docker导出离线镜像
docker save -o ./xxx.tar <tag>:<version>

## docker导入离线镜像
docker load -i ./xxx.tar
