I apologise if I have put this into the wrong discussion topic/area in the forum, I am not entirely sure where it belongs.
I am trying to run docker behind a proxy on a linux/ubuntu server machine. I have configured every proxy on the box (FTP/HTTPS/HTTP), I have also configured the Docker proxies mentioned here: https://docs.docker.com/config/daemon/systemd/#httphttps-proxy and https://stackoverflow.com/a/28093517/4261713
I have the docker service set to auto-start on machine boot, however, unless I log onto the machine and run sudo service docker restart
those settings are ignored, and docker fails to use a proxy. This is all fine, we have a work around for now (logging in after reboot and restarting docker), but I need to be able to use this machine remotely using auto-builds/deployments etc. and not worry about restarts (e.g.: if power is lost and machine auto restarts on power restoration). Without restarting the service, the builds break as docker service tries to connect directly, not through the proxy.
I have emailed Docker support, and have waited around 4 weeks for them to reply with no luck. This problem is more than likely me not understanding linux services/daemons. Can someone help me out?
To confirm what I have already tried:
-
I have created the
http-proxy.conf
in/etc/systemd/system/docker.service.d
and created the Environment variable there for the proxy. -
I have tried to modify the docker service init.d file by adding to the
"DOCKER_OPTS"
variable at the top using-e "HTTP_PROXY=http://addressofproxy:portofproxy" -e "HTTPS_PROXY=http://addressofproxy:portofproxy"
However, this also has made no difference and I still need to restart the service after a reboot! -
I have also set/configured the client config in
~/.docker/config.json
to have the proxies in.
The proxy is definitely up, running and operational. It’s the corporate proxy, I can WGET/CURL successfully prior to restarting the docker service so its not that the proxy isnt working.
