I was working on this a while back, and recalled I had this branch; should check if the validation/warning is printed in the right part of the code 😅 (may need a unit test as well), but thought; let me push this |

Should this be logrus? I think usually we just print directly to stderr? But also it's weird to write to stdio in this package.

I think I used it based on other examples I found in the code-base (e.g.
cli/cli/compose/loader/loader.go

Is a warning enough? e.g. “Warning: your data has just been exposed” secure by default, says that it should be an error (no deploy). |
|
For backwards compatibility, I think it needs to just be a warning. |
|
Having a warning is an improvement. Is any one looking at adding support for specifying addresses? |

Swarm Mode services don't support binding to a specific IP-address. Print a warning that the IP-address will be ignored if one is specified.
