A simple docker image which takes a Cloud Config file and makes an ISO suitable for creating a CoreOS instance.
- /input: Directory containing the config YML file. Only the first file in the directory is used.
- /output: Directory containing the resulting ISO file, using the YML file's filename.
docker -it --rm run \
-v /Users/bob/coreos-config/files:/input \
-v /Users/bob/coreos-config/iso:/output \
