Deploying rdap-server

The server is a typical servlet Java WAR; so, simply put it into a servlet container. The following is an improvised example on how this might be done in Ubuntu/Tomcat; if any other means or environments are flavored, knock yourself out. (Payara and Wildfly have been tested as well as Tomcat).

Info General recommendation: if RedDog’s server will be at a production environment, configure a load balancer or a reverse proxy to protect the server.

Info When configuring the balancer/proxy, the context must be the same as the server. E.g. if the backend server is at example.com:8080/rdap, then the frontend service should be at example.com/rdap (note that the server context is /rdap).

Install Java

sudo apt-get install openjdk-8-jre

Install Tomcat

# Ubuntu repositories aren't used because their Tomcat is rather old.
# You will probably need to adapt this link because it keeps changing.
# See www-us.apache.org/dist/tomcat/tomcat-8
wget www-us.apache.org/dist/tomcat/tomcat-8/v8.5.23/bin/apache-tomcat-8.5.23.tar.gz
tar -xzvf apache-tomcat-8.5.23.tar.gz

Install RedDog on Tomcat

mkdir $CATALINA_HOME/webapps/rdap
cd $CATALINA_HOME/webapps/rdap
# www.reddog.mx/server-download.html
wget https://github.com/NICMx/releases/raw/master/RedDog/rdap-server-1.4.0.war
jar -xvf rdap-server-1.4.0.war
rm rdap-server-1.4.0.war

Add the data access implementation to the classpath

mv <path-to-your-implementation> WEB-INF/lib

For example:

mv ~/Downloads/rdap-sample-daa-impl-0.0.2.jar WEB-INF/lib

If classpath only contains one implementation and it includes a service provider configuration file, that’s all that it needs. Otherwise state the hub class of the intended implementation in the data-access.properties file.

echo "data-access-implementation = mx.nic.rdap.sample.SampleHub" > WEB-INF/data-access.properties

If the implementation requires configuration, now would be a good time to tweak it by adding more key-values to data-access.properties. This file is rdap-server’s expected data access configuration file.

Start Tomcat


RedDog server is now running and serving data provided by the implementation.
