Docker安装

本文以阿里云镜像x86_64 debian系统为例：

1.安装必要的一些系统工具

1 2	sudo apt-get update sudo apt-get install ca-certificates curl gnupg

2.信任 Docker 的 GPG 公钥

1 2	sudo install -m 0755 -d /etc/apt/keyrings curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/debian/gpg \| sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

3.写入软件源信息

echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://mirrors.aliyun.com/docker-ce/linux/debian \
  "$(. /etc/os-release && echo "$VERSION_CODENAME")" stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

4.安装Docker

1 2	sudo apt-get update sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

具体可参考:https://developer.aliyun.com/mirror/docker-ce

国外服务器可以尝试一键脚本安装:

1	curl -fsSL https://get.docker.com \| bash -s docker

修改镜像源

sudo nano /etc/docker/daemon.json
#添加镜像地址
{
  "registry-mirrors": ["https://xxxxxxxx.mirror.aliyuncs.com"]
}
#重载daemon并重启Docker
sudo systemctl daemon-reload
sudo systemctl restart docker
