Running on Docker

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

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

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

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.
SSH into the Kubernetes node using one of the following commands:
```
ssh core@<NODE_IP> or vagrant ssh node-01
```

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

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

Deploy the application.
```
./deploy.sh
```
