This docker container establishes a localtunnel pointing to a configurable endpoint.

The following environment variables need to be populated:

• LT_LOCAL_HOST - the host to which the tunnel should point. Set this to a URL in a container to which this container has access, for instance: my-other-container or 127.0.10.10
• LT_PORT - which port on the host LT_LOCAL_HOST the tunnel should be pointed to.
• LT_SUBDOMAIN - the subdomain that you want to receive.
• LT_HOST - to which localtunnel server the tunnel should be established. Defaults to https://localtunnel.me.

Keep in mind to enable autorestart for the container if you want it to reestablish the tunnel if it dies.
