First, create an overlay network to isolate and secure service traffic:
$> docker network create -d overlay demo 1se1glh749q1i4pw0kf26mfx5
Next, create the service with websocket endpoints:
$> docker service create \ --name demo \ --network demo \ --detach=false \ --label com.docker.lb.hosts=demo.local \ --label com.docker.lb.port=8080 \ --label com.docker.lb.websocket_endpoints=/ws \ ehazlett/websocket-chat
Note: for this to work, you must have an entry for
demo.localin 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
two instances of your browser and text should be displayed on both instances as you type.
