Docker 是一个开源的应用容器引擎,可以打包、发布和运行应用。以下是在您的系统上安装 Docker 的步骤。
安装 Docker
系统要求
在开始安装之前,请确保您的系统满足以下要求:
- 操作系统:Ubuntu 18.04 或更高版本,CentOS 7 或更高版本,Debian 9 或更高版本
- 硬件:64 位处理器
安装步骤
- 更新系统包列表:
sudo apt-get update
- 安装 Docker:
sudo apt-get install docker-ce docker-ce-cli containerd.io
- 启动 Docker:
sudo systemctl start docker
- 验证安装:
sudo docker run hello-world
如果一切正常,您将看到以下输出:
Hello from Docker!
This message shows that your installation appears to be working correctly.
To generate this message, Docker took the following steps:
1. The Docker daemon was started.
2. The Docker client contacted the Docker daemon.
3. A new container from an image with ID hello-world was created.
4. That container was started.
5. The `/hello` command in that container was executed, which outputs the "Hello from Docker!" message.
6. The container was terminated.
