Tink Worker
Tink Worker is an agent that runs in the operating system installation environment. It is responsible for retrieving workflow actions from Tink Server and executing them. Actions are published as Docker containers with Tink Worker acting as their launcher. When an action finishes, Tink Worker reports the status to Tink Server
In Hook, Tinkerbell’s default operating system installation environment, Tink Worker is launched by a multi-staged process. A small program called hook-bootkit is launched as a serivce, reads the Kernel command line for Tink Worker specific parameters, then launches Tink Worker as a Docker container. See the LinuxKit configuration file and documentation for how hook-bootkit is launched.
