AWS SigV4 Auth Plugin for Cassandra

This repo contains example code for using the AWS SigV4 Auth Plugin for Cassandra. These are based on the documentation
for the plugin at https://docs.aws.amazon.com/mcs/latest/devguide/identity-and-access-mgmt.html#IAM.Samples.Roles.

Building

In order to build the example code, you will need Maven version 3.6.3 or higher, which you can obtain from
https://maven.apache.org/. Once you have Maven installed, you can build a shaded (all dependencies included) JAR with
the command:

 mvn package

Once this is complete, you should have an target/aws-sigv4-auth-cassandra-java-driver-examples-1.0.3.jar file.

EC2

The OrdersFetcher is a standalone class for retrieving orders from the acme.orders table, as part of the example in the
documentation at https://docs.aws.amazon.com/mcs/latest/devguide/identity-and-access-mgmt.html#IAM.Samples.Roles.

You can copy the shaded JAR, along with the cassandra_truststore.jks file, to an EC2 instance that has an associated IAM role for MCS
access. You can execute the JAR with the command:

 java -Djavax.net.ssl.trustStore=./cassandra_truststore.jks \
   -Djavax.net.ssl.trustStorePassword=amazon \
   -jar aws-sigv4-auth-cassandra-java-driver-examples-1.0.3.jar \
   <region> <endpoint> <customer ID>

For example, to lookup orders for our pretend customer “1234” in us-east-2:

 java -Djavax.net.ssl.trustStore=./cassandra_truststore.jks \
   -Djavax.net.ssl.trustStorePassword=amazon \
   -jar aws-sigv4-auth-cassandra-java-driver-examples-1.0.3.jar \
   us-east-2 cassandra.us-east-2.amazonaws.com 1234
