What is the KAAZING Gateway?

The Kaazing Gateway is a network gateway created to provide a single access point for real-time web based protocols that supports load balancing, clustering, and security management. It is designed to provide scalable and secure bidirectional event-based communication over the web; on every platform, browser, and device.

How to use this image

Up and Running

By default the gateway runs a WebSocket echo service similar to websocket.org.

You must give your gateway container a hostname. To do this, use the docker run -h somehostname option, along with the -e option to define an environment variable, GATEWAY_OPTS, to pass this hostname to the gateway configuration (your hostname may vary):

Note: the additional GATEWAY_OPTS options, -Xmx512m -Djava.security.egd=file:/dev/urandom, are added in order to preserve these values from the original Dockerfile for the gateway. The -Xmx512m value specifies a minimum Java heap size of 512 MB, and -Djava.security.egd=file:/dev/urandom is to facilitate faster startup on VMs. See the Dockerfile link referenced above for details.

You should then be able to connect to ws://somehostname:8000 from the WebSocket echo test.

Note: all of the above assumes that somehostname is resolvable from your browser. You may need to add an etc/hosts entry for somehostname on your dockerhost ip.

Custom Configuration

To launch a container with a specific configuration you can do the following:

For information on the syntax of the Kaazing Gateway configuration files, see the official documentation (specifically the *For Administrators* section).

If you wish to adapt the default Gateway configuration file, you can use a command such as the following to copy the file from a running Kaazing Gateway container:

As above, this can also be accomplished more cleanly using a simple Dockerfile:

Then, build with docker build -t some-custom-kaazing-gateway . and run:

GATEWAY_OPTS

For more information on the GATEWAY_OPTS environment variable, see Configure Kaazing Gateway Using the GATEWAY_OPTS Environment Variable.
