[Summary] Some of the more popular Docker basic images

With the continuous development of information technology, the application of virtualization technology is becoming more and more widespread. Among many virtualization technologies, Docker is increasingly favored by developers because of its lightweight, fast, and easy-to-use characteristics. favor. People can use Docker to build and deploy applications. However, before using Docker, we must first choose a base image that suits us. So, how to choose a Docker base image? This article will introduce you to some of the more popular Docker basic images and provide some useful reference opinions to help you make your choice.

1. Official Docker Image

The official Docker image is an image maintained by Docker officials. These images have been tested and certified by Docker officials and are very safe and reliable. All components of the official Docker image are developed and maintained by a professional development team, which can ensure good stability during runtime and can be updated and upgraded relatively easily. For example, we can use official Docker images to run MySQL, Nginx, Tomcat and other services.

2. Alpine Linux Image

Alpine Linux is a lightweight, safe, and simple Linux distribution, which is a very good choice for Docker. Compared with traditional Linux distributions, Alpine Linux adopts many streamlined strategies to reduce the size of containers. Alpine Linux also includes some security features, such as grsecurity and PIE (Position Indepent Executable), which can effectively reduce potential security vulnerabilities. Common services such as MySQL, Nginx, etc. can also use Alpine Linux to build Docker images.

3. Ubuntu Mirror

Ubuntu is one of the most popular Linux distributions. It is a fork of Debian and provides users with a complete and stable development environment. As a widely used Linux distribution, Ubuntu's community has many seemingly useful software packages that can meet some of our special needs. The Ubuntu image is also a very popular Docker base image.

4. CentOS Image

CentOS is a Linux operating system based on Red Hat Enterprise Linux (RHEL). The official Docker image is very stable and available. It is one of the preferred Linux distributions used by many businesses and individuals. CentOS images have good stability and can be easily and safely upgraded.

In short, when choosing a Docker base image, we must first choose according to our specific needs. For example, if we want the Docker image to be small enough and secure, we can choose the Alpine Linux image; if we need a long-term supported Linux distribution, then we can choose the Ubuntu or CentOS image. No matter which Docker base image we choose, before building a Docker container, we need to perform some necessary configuration and optimization on it to ensure the performance and reliability of the container.
