- 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.
