Automate the Deployment of Your .war Application on a Payara-Full Pod in Kubernetes

Deploying applications in a Kubernetes environment can sometimes seem daunting, especially when you've been manually transferring and deploying your .war files inside a Payara-Full Pod. If you're tired of the manual process and looking for a reliable way to automate it, you've come to the right place. In this post, we will break down how to automate the deployment of your application effectively, saving you time and effort in the process.

The Problem: Manual Deployment Process

Currently, you are deploying your .war application by following these manual steps:

Copying the .war file into the Pod using the command:

Accessing the Pod console using:

Logging into the Payara console and deploying the application using:

This manual process can be tedious and leaves room for human error. Hence, automating this deployment becomes essential for efficiency and reliability.

The Solution: Automated Deployment Through Payara Autodeploy

To streamline your deployment process, you can utilize Payara’s autodeploy feature, which allows you to automatically deploy applications placed in a specific directory. Here's how you can achieve that:

Step 1: Prepare Your Payara Image

You may choose to create a custom Payara image with your .war file preloaded. This way, every time you deploy your Pod, the application is already included. However, a simpler method is to place your application in the autodeploy directory.

Step 2: Use the Payara Autodeploy Directory

Every Payara instance has an autodeploy directory. Follow these steps to utilize it:

Locate the Autodeploy Directory:
The autodeploy directory is located at:

Replace [your-domain] with the specific domain name that your Payara instance is using.

Copy Your .war File to Autodeploy:
Instead of manually copying it to the Pod, prepare your Kubernetes deployment configuration to copy your .war file directly to the autodeploy directory inside the container. You can do this using a Kubernetes ConfigMap or by modifying the volume mounts in your Pod specification.

Automate the Deployment:
Once the .war file is placed in the autodeploy directory and the Pod is restarted, Payara will automatically deploy the application. You can restart the Payara service using:

Upon restart, Payara will detect the new .war file in the autodeploy directory and deploy it for you.

Step 3: Example Kubernetes Deployment Configuration

Here’s a simplified snippet of what your Kubernetes deployment configuration might look like:

Benefits of Automation

Efficiency: No manual steps are required, saving you setup time.

Consistency: Every deployment is done through the same process, reducing potential errors.

Ease of Updates: Simply update your .war file, and configure the Kubernetes manifest to handle it seamlessly.

Conclusion

Automating the deployment of your .war file on a Payara-Full Pod in a Kubernetes cluster can drastically improve your workflow. By making use of Payara’s autodeploy feature and adjusting your Kubernetes deployment configurations, you can simplify the entire process and focus on what truly matters – developing your application!

Now that you have a clear methodology, give it a try and simplify your deployment approach today!
