Docker is a container runtime, ultimately run on containerd. Docker is a packaged and more user friendly version with a graphical interface as well as a command line interface suite. Although it has many challengers and potential usurpers, docker remains the go-to tool for containers.
An oversimplification is that a container can be thought of as a much smaller VM. In general VM's require virtualization at the hardware level, hosts an entire OS complete with it's own kernel. A container on the other hand can share resources with it's hosts, leverages user-space a bit better, and can often run only what is necessary for the application. Ultimately, a container is more portable, and consistent than a VM and helps to eliminate the "it worked on my machine" issue.
