By default, Fleet will try to connect to servers running on default ports on localhost. Depending on your browser's settings, you may have to click through a security warning.
If you're using Docker via [Docker Toolbox](https://www.docker.com/products/docker-toolbox), you may have to modify the default values use the output of `docker-machine ip` instead of `localhost`. There is an example configuration file included in this repository to make this process easier for you. Use the `--config` flag of the Fleet binary to specify the path to your config. See `fleet --help` for more options.
