Follow the steps given below run a WSO2 product as a service on Private PaaS, on Docker:

 

Step 1: Deploy Private PaaS on a proffered IaaS

For more information on deploying Private PaaS, see Deploying PPaaS on a Preferred IaaS.

 

Step 2: Downloading the Product pack

Copy the respective product pack in the .zip format to the packs folder, which is in the /etc/puppet/modules/wso2installer/files/<SERVER_NAME> directory. 
Example: When configuring ESB navigate to the /etc/puppet/modules/wso2installer/files/wso2esb481/packs directory.

You can download the product pack from the respective products download page.

Example: Download ESB from here.

 

Steps 3: Importing the Docker image to the nodes

  1. Navigate to the <PRIVATE-PAAS-CARTRIDGES>/wso2esb/4.8.1/docker directory.

    cd <PRIVATE-PAAS-CARTRIDGES>/wso2esb/4.8.1/docker
  2. Run the build.sh file to build the Docker image.

    This will copy the plugins and the template module to the Docker image.

    ./build.sh
  3. List the Docker images.

    docker images

    Example response format: If you have successfully build the Docker image, you will get the following as a response:

    wso2/das        3.0.0              ac57800e96c2        2 minutes ago         777.6 MB
  4. Save the new image to a .tar file.

    docker save <NEW_IMAGE_NAME> > <LOCATION_OF_OF_TAR_FILE>

    For example:

    docker save myppaasimage > /tmp/myppaasimage.tar
  5. Copy the Docker image to the Kubernetes minion nodes.

    scp <IMAGE_NAME>.tar core@<NODE_IP>:

    Example:

    scp myppaasimage.tar core@172.17.8.102:

    Execute the kubectl get nodes command to get the IP address of the Kubernetes nodes.

  6. SSH into the Kubernetes node using one of the following commands:

    ssh core@<NODE_IP> or vagrant ssh node-01
  7. Load the .tar file to the Kubernetes node.

    docker load < <LOCATION_OF_OF_TAR_FILE>

    Example:

    docker load < /tmp/myppaasimage.tar

If there is more than one Kubernetes node, repeat step 4, 5 and 6 for the remaining nodes.

 

Step 4: Running the product as service on Private PaaS

  1. Navigate to the preferred WSO2 products application sample directory.

    cd <PRIVATE_PAAS_CARTRIDGES_HOME>/<SERVER_NAME>/<VERSION>/samples/applications/<SERVER_NAME>-<VERSION>-application/scripts/<IAAS>

    Example:

    cd <PRIVATE_PAAS_CARTRIDGES_HOME>/wso2das/3.0.0/samples/applications/wso2das-300-application/scripts/mock
  2. Deploy the application.

    ./deploy.sh
