Support for NTLM based proxies

chrsoo commented 7 years ago

Expected behavior

Docker uses the Windows default credentials to access internet resources through a NTLM based proxy

Actual behavior

Docker times out with a message that it cannot access the requested resource, e.g.

$ docker build .
...
Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

Information

Diagnostic ID is 9C89F33A-AA87-4CBF-B00C-1A004A366034/2017-09-04_13-00-29
Using CNTLM as a workaround does not work, cf #1057
A potential but ugly solution is to use COM from Go, cf. this Stack Overflow issue.

Steps to reproduce the behavior

Behind a NTLM proxy run any Docker command that requires network access, e.g.

docker build .

One option you can use is a nexus server that would mirror the docker hub.

I did not know that Nexus 3 supports proxying Docker but it makes total sense, thanks for the tip! We are in the process of upgrading from Nexus 2 to Nexus 3 and it will now become a prerequisite for Docker adoption at my workplace unless support for NTLM proxies is implemented.

You’re better off having one anyway. That way you can have your own images hosted in-premise. Along with other benefits like Maven artifacts, site generation targets etc.
