2023-12-21 ยท Full Changelog


@steiler added support for container healthchecks in #1426. Now you can specify healthcheck parameters for your containers in the lab topology file and Containerlab will configure the healthcheck for you.

This allows you to monitor health of your containerlab nodes as well as serves as a prerequisite for the upcoming dependency manager improvements to create dependencies on healthiness of the lab nodes.
