Mesos Artifacts for WSO2 products provide Marathon application definitions per product profile to deploy WSO2 products in a clustered manner on Mesos DC/OS.

For example, for WSO2 ESB the following artifacts are available for deployment on Mesos DC/OS. 

  • wso2esb-default.json
  • wso2esb-manager.json
  • wso2esb-worker.json

In addition, it has the Marathon application definition for its Configuration Registry database.

  • mysql-esb-db.json

As evident from the above file list, there is a Marathon application definition for default, worker, and manager WSO2 Carbon profiles of WSO2 ESB. The relevant Marathon applications for a worker manager profile is used in a worker manager separated cluster.

The following diagram illustrates the high-level architecture of a clustered WSO2 product deployment on Mesos, using Manager and Worker separation.

 

The following are the steps required to deploy a WSO2 product in a distributed manner on Mesos.

Step 1 - Build and load the WSO2 product Docker image

  1. Build the WSO2 product Docker image with the relevant profiles, based on the instructions provided in step 1 in the Deploying a WSO2 Product on Mesos section.
  2. Load the WSO2 product Docker images to the Mesos node, based on the instructions provided in step 2 in the Deploying a WSO2 Product on Mesos section.

Use the relevant profiles to build the Docker images.
For example, when the following command is executed for an ESB 4.9.0 manager - worker separated deployment, it builds the wso2esb-manager-mesos and wso2esb-worker-mesos Docker images.

build product profile docker images
/build.sh -v 4.9.0 -s mesos -r puppet -l manager|worker

After the build is successful, issue the docker images command to list the images that were successfully built.

Step 2 - Deploy the WSO2 product on Mesos in a distributed manner

Execute the following command to trigger the distributed deployment.

./deploy.sh -d

 

Step 3 - Access the UIs

Add a host entry in the /etc/hosts file (for Linux) for the Marathon LB hostname marathon-lb.marathon.mesos, resolving to Marathon Load Balancer Host IP.
For example, if the Marathon Load Balancer Host IP is 192.168.65.111, the /etc/hosts file entry is as follows:

/etc/hosts file
192.168.65.111	marathon-lb.marathon.mesos
