RancherOS behind a corporate proxy.

[Thomas Attree]

This may be rather obvious but I've not been successful in setting this up.

How do I define a proxy server to use for user docker to use when contacting public repositories?

I've attempted to set environment variables like I would normally but I think I'm missing something. Has anybody else done this?

Cheers!

To setup a proxy with docker that requires setting the HTTP_PROXY environment variable.  In the latest release dev build of RancherOS (v0.3.1-rc2), this can be set through a configuration file.  You can edit /var/lib/rancher/conf/docker and put the following in the file

export HTTP_PROXY=http://example.com

Upon restart or restarting the user docker (sudo system-docker restart docker) the environment variable will take effect.  There are two issues with this approach though.

1) We can create that file during from cloud-init, so it is not possible to do this on first boot
2) This only impacts user docker and not system docker

I believe we should add a feature to RancherOS to make this easier.  We will try to get this into RancherOS v0.3.1.

I am using an authenticated proxy and when I try this, I get an error saying unknown port tcp/mypassword. Using https_proxy=https://myuser:mypassword@proxy:port format

Looks like this format, although a common for many Linux´s flavors, is not supported. So, what to do when you need to authenticate against the proxy server?

Thanks

I believe, the best option in this case is a transparent proxy.
