Is there a 32-bit version of docker?

Docker is one of the most popular containerization technologies currently. It provides a cross-platform way to package and deploy applications, making it easier for developers to write and deploy applications. As for Docker support, most current operating systems are 64-bit. So the question is, does Docker have 32-bit?

First of all, it should be noted that Docker does not officially support 32-bit systems. The reason is that Docker needs to use the latest Linux kernel features, and these features can only be fully supported on 64-bit systems. Therefore, if you want to use Docker, you need to make sure your operating system is 64-bit.

However, not all applications require 64-bit, and some applications can run on 32-bit systems. If your application only requires 32-bit operating system support, then you can use some unofficial Docker versions to run containers on 32-bit operating systems.

Among them, Diet Docker is a version of Docker that can run on 32-bit systems. It deletes some unnecessary dependencies and components in Docker, reducing the size of Docker to the minimum and supporting 32-bit systems. . Using Diet Docker, you can create and run containers on 32-bit systems to achieve the purpose of deploying applications across platforms.

In addition, there is a project called Docker PaX that provides a Docker installation script specially designed for 32-bit systems. It uses PaX kernel protection technology to allow containers to run safely on 32-bit systems.

In summary, although Docker officially does not support 32-bit systems, some unofficial Docker versions, such as Diet Docker and Docker PaX, can run on 32-bit systems. Although these versions do not have all the features of the official version, they can also provide reliable containerization support for applications that only require 32-bit operating system support.

In short, if you need to run Docker on a 32-bit system, you may consider using these unofficial Docker versions to do it. But at the same time, it should be noted that you need to be more careful when using these versions to ensure the safe operation of the container.
