What’s the difference between Docker Compose and Kubernetes?

Question

Containers:

Docker:

Docker is a popular implementation of the technology that allows applications to be bundled into a container.
docker is a command-line tool to manage images, containers, volumes, and networks

Docker Compose

Docker Classic Swarm

Docker swarm has been abandoned by Docker Inc. and is not being actively maintained or supported.
Docker Swarm is for running and connecting containers on multiple hosts.
Docker Swarm is a container cluster management and orchestration tool.
It manages containers running on multiple hosts and does things like scaling, starting a new container when one crashes, networking containers …
The Docker Swarm file named stack file is very similar to a Docker Compose file
The only comparison between Kubernetes and Compose is at the most trivial and unimportant level: they both run containers, but this says nothing to help one understand what the two tools are and where they are useful. They are both useful for different things

Kubernetes

Kubernetes (K8S) is a distributed container orchestration tool initially created by Google
It was open-sourced in 2014 and handed over to the Cloud Native Computing Foundation (CNCF) the following year
The CNCF is an industry body with hundreds of members drawn from the majority of large cloud, software and hardware companies
At the time of writing (late 2021) there are nearly a thousand K8S related projects split into around twenty classes with a total of over $21 billion dollars in funding
Kubernetes (2021) is the most popular distributed system orchestrator in the world with 88% adoption
Because of its near ubiquity, K8S has become the most popular contemporary platform for innovative system development in 2021
Kubernetes is a competitor (more or less) to Docker swarm but does more stuff than docker swarm i.e a popular choice.
