安装docker

安装相关依赖

sudo apt-get install ca-certificates curl

添加密钥

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

网络原因curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc 可能会出现 curl: (35) Recv failure: Connection reset by peer，可以自行重试多执行几次，如果还不行可以使用阿里云或者其他的镜像加速

设置仓库地址

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

安装docker

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

换源

非必须，具体源站请自行查找

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'{  "registry-mirrors": "源地址"}EOF

sudo systemctl daemon-reload

sudo systemctl restart docker
