A quick python script to list, test speed and download a CentOS ISO image. I'm using it just to avoid going on CentOS mirrorlist and lookup the URL to wget. It works with CentOS 6, 7 or 8.

The scripts have basically the same functionality but

• get-iso.py is in python 3 and it uses threads
• get-iso-2 is in python 2, here for historical reasons and doesn't use threads. I'm also not updating it..

This is pretty much a learning experiment, but get-iso.py is actually working quite well, I'm using it to download ISOs for KVM.

Prerequisites: pip3 install requests urllib3 pyOpenSSL bs4

Then get the py script and make it executable.

./get-iso.py (-v,-t,-d,-s)

Arguments:

• -v or --version, select the CentOS version. Valid options are 6, 7 or 8. Default is 7 (CentOS7).
• -d or --download, show the URL with the best download speed and then download the MINIMAL ISO, which for CentOS8 is the boot ISO since the full DVD is over 6 GB.
• -t or --tree, show best speed OS directory tree and exit. Useful for Anaconda kickstart.
• -s or --speed, show the speed of each URL tested.

Check the best speed and then download the latest CentOS8 ISO.

./get-iso.py -v 8 -d
