Hi,
same problem here.
I’m behind a corporate proxy. The host system is able to reach the Internet via proxy and custom DNSs.
So, based on what I find in the official documentation, these are the steps I did:
- Create a file called
/etc/systemd/system/docker.service.d/http-proxy.conf
and inserted the Proxy configuration
systemctl daemon-reload && systemctl restart docker
-
systemctl show --property=Environment docker
shows that the new Proxy variable correctly set
- I also configured the corporate DNS IPs in
/etc/docker/daemon.json
to make sure the proxy is resolved within the container
After that, I wanted to test if the Internet connection works within a container:
docker run -it ubuntu bash
and try to perform an apt-get update
root@2496ee44ee0c:/# apt-get update
Err:1 http://archive.ubuntu.com/ubuntu bionic InRelease

If I type env
I can see the HTTP_PROXY
and http_proxy
variables are both set and the /etc/resolv.conf
file shows the DNS used by the corporate.
I have also set net.ipv4.ip_forward=1
on my Centos 7 installation, but no luck with it. There’s no way to reach the proxy from within the container. Please help.
