32.2. GOOGLE_PING Configuration

Red Hat JBoss Data Grid works with Google Compute Engine in the following way:
  • In Library mode, use the JGroups' configuration file default-configs/default-jgroups-google.xml or use the GOOGLE_PING protocol in an existing configuration file.
  • In Remote Client-Server mode, define the properties on the command line when you start the server to use the JGroups Google stack ( see example in Section 32.2.1, “Starting the Server in Google Compute Engine”).
To configure the GOOGLE_PING protocol to work in Google Compute Engine in Library and Remote Client-Server mode:
  • Use JGroups bucket. These buckets use Google Compute Engine credentials.
  • Use the access key.
  • Use the secret access key.

Note

Only the TCP protocol is supported in Google Compute Engine since multicasts are not allowed.

32.2.1. Starting the Server in Google Compute Engine

This configuration requires access to a bucket that can only be accessed with the appropriate Google Compute Engine credentials.
Ensure that the GOOGLE_PING configuration includes the following properties:
  • the access_key and the secret_access_key properties for the Google Compute Engine user.

Example 32.1. Start the Red Hat JBoss Data Grid Server with a Bucket

Run the following command from the top level of the server directory to start the Red Hat JBoss Data Grid server using a bucket: 
bin/standalone.sh
  -c cloud.xml
  -Djboss.node.name={node_name}
  -Djboss.socket.binding.port-offset={port_offset}
  -Djboss.default.jgroups.stack=google 
  -Djgroups.google.bucket={google_bucket_name}
  -Djgroups.google.access_key={access_key}
  -Djgroups.google.secret_access_key={secret_access_key}
  1. Replace {node_name} with the server's desired node name.
  2. Replace {port_offset} with the port offset. To use the default ports specify this as 0.
  3. Replace {google_bucket_name} with the appropriate bucket name.
  4. Replace {access_key} with the user's access key.
  5. Replace {secret_access_key} with the user's secret access key.
