Docker is a container operating system. Containers reduce the requirement to directly manage a server's operating system in the same way that virtual machines remove the necessity to directly control server hardware. Docker is pre-installed on all of the servers and offers straightforward commands for managing containerized applications.

Kubernetes, in contrast to Docker, is a platform for executing and controlling containers from a wide variety of container runtimes. Kubernetes is compatible with many container runtimes. These include Docker containers, CRI-O, as well as any application of the Kubernetes CRI (Container Runtime Interface).

It is possible to use Docker containers on AWS EC2 by running Docker. Creating an IAM user with administrative privileges, setting up an AWS account, and installing the Docker CLI are all prerequisites. Docker Hub provides images that you may pull and execute in containers, which you must expose on port 80.

Docker is a free and public software environment for creating, sharing, and running software containers. Software can be released more quickly because of Docker's ability to decouple apps from their supporting infrastructure. Docker allows you to manage the infrastructure in the same manner that you control your apps.
