Added important disambiguation to swarm mode (#10987)
* Added important disambiguation to swarm mode

This really needs to be added, I had no idea people gave up on docker/swarm because of a misunderstanding, but it's common enough we need to clarify it.

From Docker's public #swarm slack channel:
```

Hey @channel I am about to give a talk in San Francisco to a bunch of devops experts about swarm using my ingress and reverse proxy controller https://github.com/sfproductlabs/roo and one of the organizers said swarm was deprecated, is that so? It's so much easier than kubernetes, I can't imagine losing it.
sfproductlabs/roo
A zero config distributed edge-router & reverse-proxy (supporting multiple letsencrypt/https hosts). No dependencies.

Is there something we don't know?
james_wells  4:48 PM
As of the most recent official Docker release, no Swarm is still officially part of Docker...  They merely added native support for Kubernetes
andrew grosser  4:49 PM
🙏 Phew, is there an EOL?
4:49
Thanks @james_wells
4:50
I think they going to get the grenade launchers out if I can't answer these questions
james_wells  4:51 PM
Now that is a good question and my guess is that no, there is no plan to remove it, at least before Docker 3.
andrew grosser  4:52 PM
Amazing thx, I have a system that is a startups dream and is personally saving me more than 10x using swarm, so praying it stays
bmitch:docker:  4:53 PM
Classic container deployed swarm is deprecated (I believe). Swarm mode that's integrated into the engine is still being developed by Mirantis with no EOL set.
4:53
So if someone says swarm is deprecated, make sure to ask "which swarm" they are referring to.
andrew grosser  4:54 PM
Ok thanks @bmitch
4:54
Think that's a brand thing we'll need to help change
james_wells  4:56 PM
@bmitch I am not sure I understand what you are sayin there.  Could you please explain the differences
bmitch:docker:  4:56 PM
See the disambiguation section: https://hub.docker.com/r/dockerswarm/swarm
james_wells  4:57 PM
Excellent.  Thank you sir
andrew grosser  5:02 PM
Thanks

See also this link where they are getting ready to archive the standalone swarm, aka classic swarm. https://github.com/docker/classicswarm/issues/2985#issuecomment-640486361

Comment on #2985 Why have all issues been closed?
The vast majority of issues were from 5 years ago when it was being actively developed, and the recent ones were all mistakes for swarmkit, other than some issues I resolved. Many were issues in components or Moby or other software and may be resolved. It is GitHubs (reasonable) recommendation that you close issues and PRs before archiving a repository so that people know they are not being worked on, and I was also looking to see if anyone came forward to say that they were still working on things or, indeed, actively using Swarm Classic.

That is really unfortunate...  Kubernetes is simply too expensive IMNSHO, Swarm is nice and lightweight.
andrew grosser  5:08 PM
Both the different swarms point to the same point in the documentation in the disambiguation @bmitch
bmitch:docker:  5:09 PM
Swarm mode, aka swarmkit is alive and well.
andrew grosser  5:10 PM
Whoa I can see why they were confused
bmitch:docker:  5:10 PM
If you type docker swarm init you are not running classic swarm
andrew grosser  5:11 PM
Can someone inside docker add this to the swarm docs page? I think it's important
5:12
I think something talking about 2014 was EOLd but this is still current and alive would help.
bmitch:docker:  5:12 PM
Docker themselves isn't maintaining it, that team went to Mirantis, so someone over there would need to submit the PR
andrew grosser  5:12 PM
OK, could I?
bmitch:docker:  5:13 PM
Docs are in GitHub
andrew grosser  5:13 PM
Thanks
