Incus on OpenSuse(Tumbleweed, MicroOS)

5

I’m experimenting with MicroOS at the moment (seems great for a low maintenance container host) - many thanks for packaging incus.

I’ve been building a custom iso with kiwi-ng inside a privileged tumbleweed podman container. Mounting a zram device to the build directory makes builds complete in around 4 mins (& cleaning the build directory very quick) - see my notes for kpartx & how to create a build container at that link.

  • In my image I use systemd daemons & busybox applets as much as possible (so breakage should be zero even with a rolling release)

  • To use encrypted passwords in image configuration:

SALT=$(LC_ALL=C tr -dc '[:alnum:]' < /dev/urandom | head -c50)
openssl passwd -1 -salt $SALT YOUR_PASSWORD

In your build environment setup the kiwi-ng repo & install the depends:

zypper in git kiwi-systemdeps-iso-media kiwi-systemdeps-bootloaders kiwi-systemdeps-disk-images
  • Building the oem image type generates a qemu image & an iso image:
sudo kiwi-ng --profile Standard system build \
--description $DEVOPS/kiwi/build-tests/x86/tumbleweed/test-image-MicroOS \
--target-dir $DEVOPS
  • if testing images with qemu / Virtual Machine Manager - remove the iso image in the vm configuration / apply & add it back again / apply - after each build - libvirt seems to keep the old iso in memory (but possibly this is due to my use of zram)
