Docker Hub is a cloud-based registry service which allows you to link to code repositories, build your images and test them, stores manually pushed images, and links to Docker Cloud so you can deploy images to your hosts. It provides a centralized resource for container image discovery, distri...
镜像（Image）：一个只读的模板，其中包含了运行应用所需的所有内容。容器（Container）：镜像的运行实例。

这种文件系统可以一层一层地叠加修改文件。无论底下有多少层都是只读的,只有最上层的文件系统是可写的。当需要修改一个文件时,AUFS创建该文件的一个副本,使用CoW将文件从只读层复制到可写层进行修改,结果也保存在可写层。在Docker中,底下的只读层就是image,可写层就是Container。
Note that generally, I would not recommend bind-mounting /etc/passwd into the container; if you want to run the container as the same users as the user running on the host, using the id -u approach should work fine (as in; /etc/passwd would only be used to lookup the uid for a ...

It basically involves building an image from a Dockerfile that consists of instructions about container configuration or image pulling from a Docker registry. When this image is built in our Docker environment, then we should be able to run the image, which, further, creates a container. In ou...
