About Docker
Docker refers to containerized technology, which is used to support the creation and experimentation of Linux Container. With Docker, you can use containers as lightweight, modular virtual machines, and you get a high degree of flexibility to efficiently create, deploy, and replicate containers, and migrate them from one environment to another.

Review
In the previous series, we created a database and learned to populate it with users and emails, but we haven't been able to implant into our programs yet. Before two chapters, we've seen how to create a Web form and leave a full login form.
In this article, we will build and implement our own user login system based on the Web Forms and databases we have learned. At the end of the tutorial we will implement new user registration, login and exit functions.
To keep up with this chapter,

Use Docker to deploy Gitlab and docker to deploy gitlab
The company's code server has been built using Gitosis, but it is too troublesome to manage users and permissions,Now we want to build Gitlab on the original server and install it directly using the official Gitlab method,This will cause a conflict with Gitosis, making Gitosis unavailable,To keep the two services at the same time, we thought of using

In front of our lab environment, only one Docker host container is running on this host. However, in a real environment, there will be multiple host containers that start, run, stop, and destroy related containers in these hosts, regardless of whether they are located in the same host.How can we manage such a multi-host environment efficiently?The first problem we faced was installing and configuring Docker

BackgroundAgile development has been popular for a long time, and now more and more enterprises are beginning to practice agile development advocated by people-centric, iterative, progressive development concept. The first goal of introducing Docker technology in this scenario is to use the virtualization provided by Docker to create a reusable development environment for the development team, allowing t
