Using the new dns block inside the network stanza with mode = "bridge" fails with:

failed to create container: API error (400): conflicting options: dns and the network mode

This is likely a duplicate of this issue. #7746

Not sure, but was this fixed on 0.12.1?

@danlsgiga It doesn't seem like it's fixed in 0.12.1 as I'm currently experiencing this error in my 0.12.1 cluster.

[danlsgiga]

@cthayer yup, same here!
