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

 

Step 1: Downloading the Product pack

Panel

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.

Info

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

Example: Download ESB from here.

 

Steps 2: Exporting the Docker image to the nodes

Panel

  1. Run build.sh file to build the docker image.

    Info

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

    Code Block
    ./build.sh

  2. List docker images.

    Code Block
    docker images

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

     

    Code Block
    wso2/das        3.0.0              ac57800e96c2        2 minutes ago         777.6 MB

...

Login to each Kubernetes minion node and pull your docker image. 
Example: Execute the following command to pull the docker image with the docker image ID wso2/esb:4.8.1

...

  2. Save the new image to a  .tar  file.
     Code Block
    docker save <NEW_IMAGE_NAME> > <LOCATION_OF_OF_TAR_FILE>
    For example:
     Code Block
    docker save myppaasimage > /tmp/myppaasimage.tar
  3. Copy the Docker image to the Kubernetes minion nodes.
     Code Block
    scp <IMAGE_NAME>.tar core@<NODE_IP>:
    Example:
     Code Block
    scp myppaasimage.tar core@172.17.8.102:
     Info
    Execute the kubectl get nodes command to get the IP address of the respective Kubernetes node.
  4. SSH into the Kubernetes node using one of the following commands:
     Code Block
    ssh core@<NODE_IP> or vagrant ssh node-01
  5. Load the .tart file to the Kubernetes node.
     Code Block
    docker load < <LOCATION_OF_OF_TAR_FILE>
    Example:
     Code Block
    docker load 
...
  1. < 
...
  1. /tmp/myppaasimage.tar
 Info
If there is more than one Kubernetes node, repeat the steps 6 and 7 for the remaining nodes.
 
Step 3: Running the product as service on Private PaaS
 Panel
  1. Navigate to the preferred WSO2 products application sample directory.
     Code Block
    cd <PRIVATE_PAAS_CARTRIDGES_HOME>/<SERVER_NAME>/<VERSION>/samples/applications/<SERVER_NAME>-<VERSION>-application/scripts/<IAAS>
    Example:
     Code Block
    cd <PRIVATE_PAAS_CARTRIDGES_HOME>/wso2das/3.0.0/samples/applications/wso2das-300-application/scripts/mock
  2. Deploy the application.
     Code Block
    ./deploy.sh
