[rhuss]

Docker has a somewhat strange syntax for the allowed image name part, i.e. it must conform to the pattern '[a-z0-9]+(?:(?:[._]|__|[-]*)[a-z0-9]+)*'. More on this here and the "official" spec here.

So if the artifact id is part of the image name, it must not contain uppercase letters (+ the other constraints described by the pattern above).

[sunels]

It is very clean for me to understand that artifactId does not meet the requirements.

I am just having difficulties to understand why getting "org.apache.http.client.ClientProtocolException" exception while expecting to get "com.x.y.x.SomeStupidException("Your artifactId does not meet requirements..bla bla bla..")"

Kind Regards

[rhuss]

You are absolutely correct (but wanted to point out, that there are still other restrictions like no more than two subsequent underscores too)

Its an issue on the Docker daemon side that it simply closes the connection without any error indication.

So you'd better validate on the client side, too, to get a meaningful error message.

I also encountered the same problem. Your method solved my problem. Thank you.
