docker-ce VS compose-cli

Yes, Kubernetes, in fact, relies on a number of other free and open source software packages. As a base, it relies on the Docker container runtime and the CoreOS Linux distribution, and it utilizes other open source projects for a number of its components, such as etcd for distributed key-value storage. The tool's core and control plane are both built in GO programming language, making it a completely Go-based application. Kubernetes itself is an open source project and has been used as a building block for other open source projects.

Container images become containers at runtime and in the case of Docker containers - images become containers when they run on Docker Engine.

So I'm surprisingly ignorant on this but I'm curious if the full docker command line tool for linux is free and open source. It seems like https://github.com/docker/docker-ce is free and open source, but it's unclear to me if the docker community edition has other components which are not free and open source since this repository is deprecated. If the base verion is free and open source, why don't open source projects just re-implement equivalents of all of the other tools docker is providing at cost, to create a full free and open source suite?

Well, Docker CE comes with a huge Disclaimer of Warranty (https://github.com/docker/docker-ce/blob/master/LICENSE). I don't think we can complain. "I should have tested it before deploying to production" it's the right thing to say.

Not sure what you mean by "Go++" that's not really a thing. Docker's engine and tooling is primarily written in Go. You can see a copy of an older version of docker easily at https://github.com/docker/docker-ce/tree/master/components/. A number of other devops tools are written in Go, as are a number of microservices out in the wild.

`docker-compose` is different from `docker compose` (with a space in between words).

The former will be replaced by the latter in the long run.

One of the goal of this new version is to be able to plug different backends like AWS ECS or Microsoft ACI. See https://github.com/docker/compose-cli. So you can docker compose and your stack is deployed on ECS instead of your local machine.
