Download the iso file required for installing the rockylinux system and extract important information

Recently, many domestic image sites have been blocked, which makes it impossible for us to pull images normally,

E.g. Centos Rockylinux、Ubuntu、Alpine、 Images at the operating system level such as Kirin cannot be downloaded,

There are also service level images such as Nginx, tomcat, MySQL, Python, etc. that cannot be downloaded. How do you make these images yourself?

This set of courses teaches you to make your own images, which can be made at the operating system level based on Iso files,

You can also mirror the code developed by Go, Python, Java, etc,

You can also mirror such open source services as Nginx, MySQL, and tomcat,

The image can be used for Docker, Containerd, Podman and other containers, as well as for k8s,

The self created image can also be transferred to the private image warehouse Harbor and downloaded at any time.
