Introduction to the containerized setup

What is a container image?​

A container image is an application together with all the required dependencies wrapped together into a single image, which basically is a compressed archive. The application that runs from a container image is called a container.

Compared to a virtual machine, a container only contains the required dependencies to run the application or service and is not bloated with other files. This makes containers very small in size and boot up almost instantly. This results in very quick deployments or updates, by simply replacing the old container.
