ubuntu安装docker arm

在Ubuntu系统上安装Docker ARM版本通常适用于那些基于ARM架构（如ARM64或ARMv7）的设备，比如支持ARM的服务器、 Raspberry Pi或一些嵌入式设备。以下是基本步骤：

1. **更新系统**:

   sudo apt-get update && sudo apt-get upgrade

2. **安装依赖库**:

   sudo apt-get install apt-transport-https ca-certificates curl gnupg lsb-release

3. **添加Docker GPG密钥**:

   curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

4. **修改apt源**:

   echo \
   "deb [arch=arm64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
   $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

5. **刷新并安装Docker**:

   sudo apt-get update
   sudo apt-get install docker-ce docker-ce-cli containerd.io

6. **启动和启用Docker服务**:

   sudo systemctl start docker
   sudo systemctl enable docker

7. **验证安装**:

   sudo docker run hello-world
