Step 3: Importing the Docker image to the nodes

Panel

  1. Download the Private PaaS cartridges from the product page.

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

    Code Block
    cd <PRIVATE-PAAS-CARTRIDGES>/wso2esb/4.8.1/docker

  3. Run the build.sh file to build the Docker image.

    Info

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

    Code Block
    ./build.sh

  4. List the Docker images.

    Code Block
    docker images

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

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

  5. 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

  6. 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 Kubernetes nodes.

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

    Code Block
    ssh core@<NODE_IP> or vagrant ssh node-01

  8. Load the .tar file to the Kubernetes node.

    Code Block
    docker load < <LOCATION_OF_OF_TAR_FILE>

    Example:

    Code Block
    docker load < /tmp/myppaasimage.tar
Info

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