Please note a recent version of docker-compose is needed to allow the environment to start with the healthcheck keywork,
It was not working with the version 1.26.2 but is ok with 1.28.2

Ah right, the feature was introduced in docker-compose 1.27.0 (see commit).

We need to find a way to restrict the version of docker-compose to use then, maybe by changing the version field value at top of docker-compose.yml file.

Actually, healthcheck it is a feature introduced in version 2.1 of Compose file format.

Bumping version to 2.1 in compose files seems to fix the observed issue (just tested with docker-compose 1.25.0 packaged in debian buster).
