I am trying to automate of building custom RasperryPI image, which includes mounting template image file to loopback filesystem and copying intended files into it. The image file is rather big (6G) and I put it on some hostimg and then copying it to task environment via
scp. Unfortunately, the transfer speed is too low and copying takes too long
... template.img 1% 115MB 95.4KB/s 18:10:00 ET template.img 1% 115MB 95.4KB/s 18:10:09 ET template.img 1% 115MB 96.0KB/s 18:03:59 ET ...
Is it possible to create some predefined
OS image or filesystem overlay to put onto existign image?
Note that I can’t use
Docker because it doesn’t support mounting loop devices without privileged mode and
CircleCI doesn’t allow this.
