I am using Ubuntu 16.04.4 LTS and my proxy configuration worked fine with this version:

> docker --version
Docker version 17.12.0-ce, build c97c6d6

I recently did and apt-get upgrade and it pulled a new version of docker-ce:

> docker --version
Docker version 18.03.1-ce, build 9ee9f40

Now I get failures of the form:

> docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: proxyconnect tcp: dial tcp: lookup http on 10.198.0.199:53: no such host.

(10.198.0.199 is our company's internal DNS server)

Here are my contents of my /etc/systemd/system/docker.service.d/10_docker_proxy.conf

[Service]
Environment=HTTP_PROXY=http://DOMAIN\\username:[email protected]:9091
Environment=HTTPS_PROXY=http://DOMAIN\\username:[email protected]:9091

I tried single and double quoting the HTTP_PROXY and HTTPS_PROXY variables:

Environment="HTTP_PROXY=http://DOMAIN\\username:[email protected]:9091"
Environment="HTTPS_PROXY=http://DOMAIN\\username:[email protected]:9091"

and

Environment='HTTP_PROXY=http://DOMAIN\\username:[email protected]:9091'
Environment='HTTPS_PROXY=http://DOMAIN\\username:[email protected]:9091'

with the same error.

It looks like is related to the DOMAIN\\ part of the username, because if I do this (i.e. don't supply a password):

Environment=HTTP_PROXY=http://DOMAIN\\[email protected]:9091
Environment=HTTPS_PROXY=http:/DOMAIN\\[email protected]:9091

I get the same proxyconnect tcp: dial tcp: lookup http on 10.198.0.199:53: no such host error, but if I leave off the DOMAIN:

Environment=HTTP_PROXY=http://[email protected]:9091
Environment=HTTPS_PROXY=http:/[email protected]:9091

I get

docker: Error response from daemon: Get https://registry-1.docker.io/v2/: authenticationrequired.

Something needs to be tweaked with the URL parsing library?

In the mean time I will be reverting to a working docker:

sudo apt-get install docker-ce=17.12.0~ce-0~ubuntu

Looks like I need to percent-encode the "\" character. This works:

Environment=HTTP_PROXY=H://DOMAIN%5cusername:[email protected]:9091 Environment=HTTPS_PROXY=H://DOMAIN%5cusername:[email protected]:9091

  • Where "H" is "http", the markup wouldn't let me enter this for some-reason.

  • Looks like things broke again when we upgraded to Ubuntu 18.04 with docker 18.05. The solution was to escape each % with %% ...
