Chapter 8, Clustering with Docker Swarm

Here are some sample answers to the questions presented in this chapter:

1. False; the standalone Docker Swarm is no longer supported or considered a best practice.
2. You need the IP address of your Docker Swarm manager, and also the token that is used to authenticate your workers against your manager.
3. You would use docker node ls.
4. You would add the --pretty flag.
5. You would use docker node promote [node name].
6. You would run docker service scale cluster=[x] [service name], where [x] is the number of containers that you want to scale by.
