Move a VM based application to Kubernetes
The IBM Cloud Kubernetes Service offers managed Kubernetes clusters with isolation and hardware choice, operational tools, integrated security, as well as insights into images and containers. Kubernetes offers many great benefits like application scalability, visibility, time savings, version control, rolling updates and more.
To move applications to Kubernetes, you need to:
Define clusters for different environment types(dev, test, and production).
Handle data storage and the importance of persistent data storage.
Apply the 12-factor principles to your application and use secrets for credentials in Kubernetes.
Build docker images and push them to IBM Cloud container registry.
Create Kubernetes deployment files and deploy the docker image to Kubernetes.
Map components between VMs and Kubernetes.
Containerize the application.
Deploy the container to a Kubernetes cluster on the IBM Cloud Kubernetes Service.
Following this tutorial, you will understand how to take an existing traditional application architecture, based on virtual machines:
To a modern container, architecture that would look similar to:
