disk size issue about docker-to-linux HOT 1 CLOSED

ive solved my own problem, gonna write it here for anyone that havent worked much with sfdisk and have the same problem.

sudo dd if=/dev/zero of=linux.img bs=${IMG_SIZE} count=XX where XX is the amount of GB the disk (or image file) has.

the second one is inside the commands given to sfdisk , size parameter.
linux.img1 : start=2048, size=size, type=83, bootable where size is as follows :

Since i dont know how partitions works at all, ive multiplied final size by amount of gb so ive got something like : ( XX * 2 * 1024 * 1024 ) - 2048

so for 4 gb image image file partition, it should be linux.img1 : start=2048, size=8386560, type=83, bootable

Im sure this may not be the appropiate solution, but it works!
