kanto-auto-deployer file change watchdog #24

Closed mikehaller closed 1 year ago

mikehaller commented 1 year ago

Background Eclipse Kanto Container Management recently implemented the automated initial deployment of containers based on json manifests. Integrators can define the "init_dirs" configuration property and kanto-cm will take care of creating and starting the containers when the service starts.

Initially, kanto-auto-deployer (KAD) in leda-utils was meant to be that feature. Now, it became obsolete. But we can implement more convenient features in KAD which will probably not be implemented in kanto-cm (as they're not for production use), to make reuse of the code.

File change watchdog Whenever a json manifest changes on disk (e.g. newly created, or touched/updated), KAD will delete the corresponding container and recreate it with the new settings. These will for example allow to add or change environment variables for a containerized process and KAD can automatically recreate the container. Kanto-cm would not pick up these changes, as in a production environment, such manual file changes are not be expected.

Note: For framing this idea, other features for KAD may be: auto-delete duplicate containers based on name, import container images from filesystem for offline installation ("AirGap")
