docker安装（debain）

sudo apt install -y apt-transport-https ca-certificates curl software-properties-common
curl -fsSL https://download.docker.com/linux/debian/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/debian $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list
sudo apt update
sudo apt install -y docker-ce docker-ce-cli containerd.io
sudo systemctl start docker
sudo systemctl enable docker
sudo docker --version
  • 安装docker-compose
# 下载Docker Compose二进制文件
sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# 设置为可执行文件
sudo chmod +x /usr/local/bin/docker-compose
# 验证安装
docker-compose --version

** 注意：下载docker-compose时候，因为需要访问外网，所以很慢，所以可以先下载到本地上传服务器。注意下载的版本最好不要是最新的，并且注意与服务器版本匹配。

  • 替换docker镜像源
sudo vi /etc/docker/daemon.json
{
  "registry-mirrors": ["https://registry.docker-cn.com"]
}
  • 这里要注意格式一定要正确，否则后面会报错
sudo systemctl daemon-reload
sudo systemctl restart docker
docker info
