Debian is a very stable and secure Linux distribution that is very cautious in updating software packages. Debian systems are designed with the long term in mind, minimizing updates and modifications by splitting software packages into core and non-core parts to reduce possible bugs and security vulnerabilities. Therefore, using the Debian base image ensures the stability and security of your application.

Debian is famous for its powerful software package management system. Its software package library maintains a large number of software packages, covering various applications. , services, and tools that can easily meet the needs of most applications. Using the Debian base image, it is easy to install the required packages and build the application.
3. Community support
Debian This distribution has extensive community support around the world, and you can get strong help and support during use. Many Docker community members are also active members of the Debian community, which means using the Debian base image has access to better technical support and documentation resources.

The Docker image based on the Debian system is easy to customize to meet the requirements of specific applications. Debian official images provide multiple different versions on Docker Hub, with different sizes, various software packages, compatible Docker CLI versions, etc. to choose from, and can be customized using Dockerfile to facilitate users to customize according to their needs. Select, modify and maintain.
To sum up, Docker chose Debian as its official image due to factors such as its stability, security, richness of the software package library, community support and ease of customization.
