Atomic Updates
Updates applied fully or not at all
Bootable Containers
deploy an OS from OCI images
But why 🤔
We all know how to build a container
Boot from OCI Images
openSUSE's tukit
podman's btrfs storage driver
container-snap
Demo
Challenges
- long debug & test cycles
tukitis very snapper & openSUSE specific- bootloaders are weird
What's left?
- actual testing & usage
- proper
/etc/handling (👉️dcermak/bindicate) - better UX
- proper kernel & bootloader update handling
- real image builder support
- finish support in
tukit - garbage collection
Go to dcermak/container-snap and give it a try!
