Docker Engine安装

官方安装步骤

# Add Docker's official GPG key:
sudo apt update
sudo apt install ca-certificates curl
sudo install -m 0755 -d /etc/apt/keyrings
sudo curl -fsSL https://download.docker.com/linux/debian/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.ascsudo tee /etc/apt/sources.list.d/docker.sources <<EOF
Types: deb
URIs: https://download.docker.com/linux/debian
Suites: $(. /etc/os-release && echo "$VERSION_CODENAME")
Components: stable
Architectures: $(dpkg --print-architecture)
Signed-By: /etc/apt/keyrings/docker.asc
EOFsudo apt update
sudo apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

一行命令复制安装（采用TUNA源）

apt update && apt install ca-certificates curl && install -m 0755 -d /etc/apt/keyrings && curl -fsSL https://mirrors.tuna.tsinghua.edu.cn/docker-ce/linux/debian/gpg -o /etc/apt/keyrings/docker.asc && chmod a+r /etc/apt/keyrings/docker.asc &&
cat > /etc/apt/sources.list.d/docker.sources << EOF
Types: deb
URIs: https://download.docker.com/linux/debian
Suites: $(. /etc/os-release && echo "$VERSION_CODENAME")
Components: stable
Architectures: $(dpkg --print-architecture)
Signed-By: /etc/apt/keyrings/docker.asc
EOF
&& apt update && apt install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin

添加镜像源

cat > /etc/docker/daemon.json << EOF
{"registry-mirrors": ["https://docker.m.daocloud.io"]
}
EOF
