Difference between docker.io, docker-cd, and Docker Desktop

Docker has evolved to provide a range of solutions for developers working with containerized applications, but choosing the right version can be confusing due to the various options available for different operating systems. While Docker is synonymous with containerization, it is important to understand the various tools and specifications involved, such as those defined by the Open Container Initiative (OCI), which includes image and runtime specifications. Container Runtimes like runc, crun, and katacontainers execute processes, while Container Engines like Docker and Podman manage image pulling and container launching. Linux users have multiple installation options, including docker.io, docker, and docker-ce, each with its pros and cons. For Windows and macOS users, Docker Desktop is the primary installation method, though it requires payment for some teams. Windows servers offer built-in support for Docker but are limited to Windows containers. The post also introduces the Octopus Workflow Builder as a tool for deploying containerized applications on AWS, emphasizing best practices like vulnerability scanning and Infrastructure as Code.
