I'm facing the following issue with my Docker containers: When I try to enter the container using
docker exec -it container-id /bin/bash
Docker (I assume it's Docker) complains with the following message:
proxy: unknown scheme: http
I have traced this back to the following environment variable that's set on my host machine, since I'm using a proxy server to access the web:
ALL_PROXY=http://myproxy:8080
The error message seems to come from the net/proxy.go file, which can be found here - the error message is issued on the last line of the file. Why would http not be a registered URL scheme in the Docker case?
As soon as I unset ALL_PROXY on the host, I can enter the container without any issues.
Environment:
Any idea how to fix this (other than unsetting the variable each time)?
I am facing the same issue with docker 1.11.2. I believe the error is coming from method FromURL.
After checking the relevant commit https://github.com/docker/docker/commit/16effc66c028a7800096ed92174ca4bceba229ad, it turns out from v1.11.0-rc1 up to v1.12.0-rc4 are including this commit.
So the solution for me is to install a lower version (I used v1.10.3) of docker toolbox, after which "docker run hello-world" works.
