-* Docker + Interval - These checks depend on invoking an external application which is packaged within a Docker Container. The application is triggered within the running container via the Docker Exec API. We expect Consul agent user has access to the Docker HTTP API or the unix socket. Consul uses DOCKER_HOST to determine the Docker API endpoint. The application is expected to run, perform health check of the service running inside the container, exit with an appropriate exit code similar to the Script check. The check should be paired with an invocation interval. The shell on which the check has to be performed is configurable which makes it possible to run containers which has different shells on the same host.
