OCI-SYSEXT

This tool aims to be a little bridge to transform an OCI image into a systemd-sysext compatible raw image.

Compile

CGO_ENABLED=0 go build -mod vendor -ldflags="-s -w"

Usage

./oci-sysext pull docker.io/alpine:latest
 ./oci-sysext create --image docker.io/alpine:latest --name my-alpine-raw --fs btrfs --os opensuse-microos

Usage notes

• Supported --fs are squashfs and btrfs

• --os flag is the /etc/os-release content of ID=, this is because systemd-sysext needs to know what systemd this will run on
