Does the Docker deployed AnQiCMS container lose its data after stopping?
Does the data really get lost after Docker deployment of AnQiCMS? — Website operation experts give you an in-depth interpretation
Hello, I am your veteran website operations manager. In the digital wave, an efficient content management system (CMS) is the foundation of website operations, and Docker, with its lightweight and portable characteristics, is gradually becoming the preferred solution for deploying various applications.AnQiCMS is an enterprise-level content management system developed based on the Go language, which has won the favor of many users with its high efficiency and customizable features.
However, when we deploy AnQiCMS to a Docker container, a core issue often lingers in the minds of many operators and technical personnel: 'If my AnQiCMS container, which I run with Docker, stops running or even gets deleted, will my website data disappear with it?'This issue is crucial because it directly relates to the stable operation and data security of our website.Today, I will analyze the data persistence of Docker containers in detail from the perspective of a senior operator, combining the actual situation of AnQiCMS.
Understanding the data lifecycle of Docker containers
To answer this question, we first need to understand how Docker containers work.You can imagine a Docker container as a temporary, independent 'little world'.It has its own file system, running the AnQiCMS application, all operations are carried out in this isolated environment.This 'small world' is very clean and reusable, but it has a default feature:Its internal filesystem is temporary.
This means that once this container is stopped and removed (for example, you rundocker rmThe command and all data it generates during runtime, including uploaded images, modified configurations, system logs, and any changes inside the container's filesystem, will vanish along with it.Just like playing a game without save, every time you turn it off and restart, everything has to start from scratch.This is clearly something we do not want to see in a production environment.
The core data composition of AnQiCMS
So, what critical data does AnQiCMS generate during runtime that we need to pay special attention to and persist? According to our understanding of AnQiCMS' functions and architecture, its data can mainly be divided into two categories:
- Database DataThis is undoubtedly the 'heart' of AnQiCMS. It contains all the website content (articles, products, pages), category information, user data, multi-site configuration, various functional modules (such as friend links, messages, keyword library) and so on.AnQiCMS usually depends on relational databases like MySQL to store this core information.
- File System Data: This data is located in the file system of the AnQiCMS application, mainly including:
- User-uploaded media resources: Images, attachments, videos, etc., these are an important part of the website content.
- System configuration fileFor example, used to manage ports, database connections, and other key settings `config.'
