If you read my previous posts, you should now have a raspberry-pi running alpine and docker. Resources are pretty limited on rpi0, so we are going to deploy programs using rust. Note: golang could have fit in there as well (and ofc all C and close to machine languages). Compiling from NOT a rpi0 Obviously, you don’t want to compile from a raspberry pi zero, unless you have all the time in the world and love waiting....
Prerequisites One raspberry pi zero W One sd card Enable all cgroups On you local linux, mount the partition containing alpine files. In the cmdline.txt, add the following: echo -ne " cgroup_enable=memory cgroup_enable=cpuset swapaccount=1" >> /run/media/youruser/xxx/cmdline.txt Docker needs all cgroups enabled, so this will do the trick On you rpi0 As simple as: sudo apk add docker sudo rc-update add docker boot sudo rc-service docker start To make sure your docker env doesn’t go in memory (512MB RAM won’t bring you far…), set it on mmcblk0p3 by editing /etc/docker/daemon....
Prerequisites One raspberry pi zero W One sd card Download Alpine linux We’ll use the almost latest version: 3.9.2 (3.9.3 would not work for some reason) The one to use for RPI is the raspberry pi (surprising :P) armhf. On your local computer (assuming you re using linux) Mount the sdcard (should be automated, if not, you probably know how to do that and you probably don’t need that tutorial)...
