watchdock is a Docker monitoring web application. The application is self contained, no additional dependencies, services (except docker :-) or servers are needed.
The docker demon needs to be exposed as IP service with activated CORS:
-H tcp://0.0.0.0:5555 -api-enable-cors See also: https://docs.docker.com/reference/api/docker_remote_api_v1.10/#33-cors-requests
Launch index.html from a browser and set the docker host and port.
You can also try watchdock directly from watchdock.org.
