Use wget to download file from Google Drive
# First need to create share link from the file, and get the FILE ID from the sharing URL, example :
# https://drive.google.com/file/d/1xlsJtCx7EJXoxGn5SjCUIQ0DGJHsDs61/view?usp=sharing, then the FILE ID will be 1xlsJtCx7EJXoxGn5SjCUIQ0DGJHsDs61
# Run below command to download file, replace FILEID and FILENAME
wget --load-cookies /tmp/cookies.txt "https://docs.google.com/uc?export=download&confirm=$(wget --quiet --save-cookies /tmp/cookies.txt --keep-session-cookies --no-check-certificate 'https://docs.google.com/uc?export=download&id=FILEID' -O- | sed -rn 's/.*confirm=([0-9A-Za-z_]+).*/\1\n/p')&id=FILEID" -O FILENAME && rm -rf /tmp/cookies.txt

Podman Issue Overlay fs does not supported
##Got podman issue when run podman command :
##Error: could not get runtime: kernel does not support overlay fs: overlay: the backing xfs filesystem is formatted without d_type support, which leads to incorrect behavior. Reformat the filesystem with ftype=1 to enable d_type support. Running without d_type is not supported.: driver not supported
##Reinstall podman and containers-common does not work
##Edit /etc/containers/storage.conf
vi /etc/containers/storage.conf
##Find storage.options and make sure below line is in there
[storage.options]
mount_program = "/usr/bin/fuse-overlayfs"
