Afterburn

This is a small utility, typically used in conjunction with Ignition, which reads metadata from a given cloud-provider and applies it to the system. This can include adding SSH keys and writing cloud-specific attributes into an environment file (e.g. /run/metadata/afterburn), which can then be consumed by systemd service units via EnvironmentFile=.

Support

The supported cloud providers and their respective metadata are listed below. On CoreOS Container Linux, the supported providers and metadata are somewhat different.
