Containerizing an EGL RUI Application

Let us understand how to containerize an EGL RUI Application and deploy it onto a Kubernetes cluster. The application itself will run inside a Docker container on a Tomcat server, and we will manage the deployment using Kubernetes manifest files (like Deployment.yaml and Service.yaml).

Containerization

Containerization is a type of virtualization in which all the components of an application are bundled into a single container image and can be run in an isolated user space on the same shared operating system. Containers are lightweight, portable, and highly conducive to automation.

Containerization allows developers to create and deploy applications faster and more securely. With traditional methods, developers write code in a specific computing environment, which often results in bugs and errors when transferred to a new location. For instance, this can happen when a developer transfers code from a desktop computer to a VM or from a Linux® to a Windows operating system.

Containerization eliminates this problem by bundling the application code with the related configuration files, libraries and dependencies required to run. This single software package or container is abstracted away from the host operating system. Hence, it stands alone and becomes portable. Basically, this container is able to run across any platform or cloud, free of issues.
