What is the difference between Docker Service and Docker Container?

Question

When do we use a docker service create command and when do we use a docker run command?

Answer 1

Docker services are like "blueprints" for containers. You can e.g. define a simple worker as a service, and then scale that service to 20 containers to go through a queue really quickly. Afterwards you scale that service down to 3 containers again. Also, via Swarm these containers could be deployed to different nodes of your swarm.

But yeah, I also recommend reading the documentation, just like @Tristan suggested.
