This article focuses on "how to use docker compose to build a fastDFS file server", interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to use docker compose to build a fastDFS file server.

Today, I will show you how to use docker compose to build a fastDFS file server. The details are as follows:

Platform: Mac M1

Remarks: about IP Address

With regard to the network model of docker, the Host mode of docker is mentioned in the above article:

If you start the container in host mode, the container will not get a separate Network Namespace, but will share a Network Namespace with the host. The container will not virtualize its own network card or configure its own IP, but will use the IP and port of the host. However, other aspects of the container, such as file systems, process lists, and so on, are isolated from the host.

The problem is that if you use the IP and port of the host, you can access the container if you enter localhost in the IP in the configuration file, but in fact it is not. The IP Address method for personal understanding (please correct if you have any questions) is as follows:
