Use websockets

Estimated reading time: 1 minute

First, create an overlay network to isolate and secure service traffic:

$> docker network create -d overlay demo

Next, create the service with websocket endpoints:

$> docker service create \
    --name demo \
    --network demo \
    --detach=false \
    --label \
    --label \
    --label \

Note: for this to work, you must have an entry for demo.local in your local hosts (i.e. /etc/hosts) file. This uses the browser for websocket communication, so you must have an entry or use a routable domain.

Interlock detects when the service is available and publishes it. Once tasks are running and the proxy service is updated, the application should be available via http://demo.local. Open two instances of your browser and text should be displayed on both instances as you type.
