how to configure docker containers proxy ?
First of all,
I tried to use the way that setted '/etc/systemd/system/docker.service.d/http-proxy.conf' (https://docs.docker.com/config/daemon/systemd/#httphttps-proxy) and it really works for docker daemon, but it doesn't work for docker containers, it seems this way just take effect for some command like 'docker pull'
I have a lot of docker containers, I don't want to use 'docker run -e http_proxy=xxx... ' command every time when I start a container.
So I guess if there is such a way automatically load the global configuration file when the container starts, I googled it and got it to set the file '~/.docker/config.json'(How to configure docker container proxy?, this way still does not work for me.
( my host machine system is centos7, here is my docker -v: Docker version 1.13.1, build 6e3bb8e/1.13.1 )
I feel that it may be related to my docker version or the docker started by the systemd service, so ~/.docker/config.json does not take effect.
I just hope that modifying configuration files will allow all my containers to automatically configure environment variables when it start (that is auto set environment variables 'http_proxy=http://HostIP:8118 https_proxy=http://HostIP:8118' when a container start, like Dockerfile param ENV) . I want to know if there is such a way? And if this way can be realised I can make the container use the host's proxy, after all, my host's agent is working properly.
But I was wrong, I tried to run a container,then set http_proxy=http://HostIP:8118 and https_proxy=http://HostIP:8118, but when I use the command 'wget facebook.com' and I got 'Connecting to HostIP:8118... failed: No route to host.', But, the host machine(centos7) can successfully execute the wget, And I can successfully ping the host in the container. I don't know why it might be related to firewalls and the 8118 port.
It is Over,
OMG.. I have no other way, can anyone help me?
ps: You can see from the screenshot below, I actually want to install goa and goagen but report an error, maybe because of network reasons, I want to open the agent to try, so...only have the above problem.
