Developer - Containerization

Thinking inside the box

Containerization is the process of bundling software and its requirements into a single image, which can be easily run and deployed on any machine. With migrations more frequently happening from on-premise to the cloud (or vice versa), companies benefit from this easy-to-deploy setup. But ‘containerizing’ an application suite goes beyond creating a Docker file. During this workshop, we’ll dive deep into topics such as networking, debugging, storage, orchestration and even containerized development setups.
