| - | Minikube needs Docker to run. | ||
| - | |||
| - | ===Introduction to Docker=== | ||
| - | |||
| - | Docker is a lightweight virtualization application that uses **images** and **containers**. | ||
| - | |||
| - | An **image** is an executable package containing everything needed to run a given piece of software, including : | ||
| - | |||
| - | * code | ||
| - | * a runtime | ||
| - | * libraries | ||
| - | * environment variables | ||
| - | * configuration files | ||
| - | |||
| - | A **container** is an instance of the image running in memory. It is isolated from the host environment by default, but can access host files and ports depending on configuration. | ||
| - | |||
| - | Containers run applications natively using the host machine kernel. As a result, the performance of a container is superior to that of a virtual machine, which must use a hypervisor to access host resources: | ||
| - | |||
| - | Docker is available in two versions **Docker-CE** (Docker Community Edition) and **Docker-EE** (Docker Enterprise Edition). To see the differences between the two versions, visit **[[https:// | ||
