<script>
jQuery(document).ready(function() {
jQuery(".wiki-content a").attr("target", "_blank");
});
</script> |
...
Step 1: Deploy Private PaaS on a proffered IaaS

Step 2: 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.

3: Importing the Docker image to the nodes
| Panel |
|---|
Navigate to the <PRIVATE-PAAS-CARTRIDGES>/wso2esb/4.8.1/docker directory. | Code Block |
|---|
cd <PRIVATE-PAAS-CARTRIDGES>/wso2esb/4.8.1/docker |
Run the build.sh file to build the docker Docker image. | Info |
|---|
This will copy the plugins and the template module to the docker Docker image. |
List the docker Docker images. Example response format: If you have 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 |
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 |
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. |
SSH into the Kubernetes node using one of the following commands: | Code Block |
|---|
ssh core@<NODE_IP> or vagrant ssh node-01 |
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 and 7 for the remaining nodes. |

4: Running the product as service on Private PaaS
| Panel |
|---|
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 |
Deploy the application.
