Let's talk about which versions of Linux systems Docker supports

Docker is an open source platform for developing, delivering, and running applications. Docker uses containerization technology to package applications into an independent running environment, making application delivery and deployment easier and more efficient. For developers who use Docker, the first thing they need to know is which versions of Linux operating systems Docker supports.

Currently, the Linux operating system versions supported by Docker include the following:

1. Ubuntu

Ubuntu is one of the most popular Linux distributions , is also one of the operating systems recommended in Docker’s official documentation. The latest version of Docker already supports the Ubuntu 20.04 LTS operating system, as well as Ubuntu 18.04 LTS and Ubuntu 16.04 LTS.

2. Fedora

Fedora is a Linux-based operating system launched by Red Hat. Docker official documentation shows that Docker supports Fedora 31 and above.

3. CentOS

CentOS is one of the enterprise-level Linux operating systems and one of the operating systems recommended in Docker’s official documentation. Docker supports CentOS 7 and above.

4. Debian

Debian is a popular Linux distribution and one of the supported operating systems listed in the official Docker documentation. Docker supports Debian 10 and above.

5. Red Hat Enterprise Linux

Red Hat Enterprise Linux is a commercial-grade operating system supported and serviced by Red Hat. Docker can be deployed and used on Red Hat Enterprise Linux.

6. Oracle Linux

Oracle Linux is a Linux distribution launched by Oracle Corporation. Docker official documentation states that Docker supports Oracle Linux 7 and above.

It should be noted that since the essence of Docker is to use the namespace isolation technology of the Linux kernel to implement containerization, in addition to the Linux operating system recommended by official documents, other Linux distributions may also support Docker. But this requires developers to conduct their own testing.

In general, Docker supports many Linux operating system versions, and they are constantly being updated and improved. If you are using Docker for application development and deployment, it is recommended to choose the aforementioned officially recommended operating system version.
