Can't pull repositories from github via HTTPS

[andradei]

I upgraded my AWS docker engine to latest stable (17.09.0-ce). It works now. Now I'm having another problem in the compilation step, which is an issue for another repo.

Thanks for helping me narrow it down. I really appreciate it.

Could you update with your Package.swift?

This sounds like a connection or DNS issue: Could not resolve host: github.com.

Can you run curl "https://github.com" inside the container?

@swizzlr I updated the OP with Package.swift. Thank you for helping.

@florianreinhart curl fails for github, google, etc., so it is a container issue. This problem, however, arises only on my AWS EC2 Ubuntu 16.04 instance. I can run curl successfully on my local machine (macOS). So would this be related to Ubuntu (or a different version of Docker)?

@andradei Have you checked your EC2 firewall rules? Can you curl from outside Docker on that machine? What networks have you attached to the container in Docker?

This works on my and many other machines, so I think it's something to do with how you're running the container, not the image itself.

@swizzlr Firewall is letting 443 traffic in/out. I can curl from outside of Docker on that instance. No networks attached, unless docker does it automatically.

I run the container with docker run -ti swift:4.0.2 /bin/sh and try to swift build -c release --static-swift-stdlib inside it.

[swizzlr]

This works on my Mac, Docker 17.09

docker run -ti swift:4.0.2 /bin/sh
...
curl https://github.com

Can you verify the same for yourself?
