docker-api conflict when using docker cookbook

[qubitrenegade]

Hello,

I am attempting to use the docker cookbook, while using the Chef audit cookbook (actually, I'm trying to use the Swarm cookbook which depends on the docker cookbook, I believe it's a compatability issue between the docker cookbook and the r-train) I get the error:

Unable to activate r-train-0.12.0, because docker-api-1.28.0 conflicts with docker-api (~> 1.26.2)

This appears to be because docker has a requirement for docker-api-1.28.0, while r-train has a dependency on docker-api ~> 1.26.2?

Is there a way to work around this other than disabling Compliance?

Thanks!

@chris-rock can the r-train runtime dependency docker-api ~> 1.26.2 be loosened to ~> 1.26 perhaps?

Thanks @qubitrenegade and @jeremymv2 for the report. We released train 0.12.1 that includes the fix proposed by @jeremymv2
