docker-machine behind corporate proxy

Question

I am trying to use docker-machine to create an instance on a private cloud (Openstack) that is behind a corporate http proxy.

Is it possible to tell docker-machine to use the proxy or do I need to have a glance image that is already pre-configure with the http_proxy env variable?

Answer 1

As previously mentioned, you can edit the file at

$HOME\.docker\machine\machines\default\config.json 

and set the HTTP_PROXY, HTTPS_PROXY and NO_PROXY variables (or delete them):

 "HostOptions": {         "Driver": "",         ...         "EngineOptions": {            ...             "Env": [               "HTTP_PROXY=http://10.121.8.110:8080",               "HTTPS_PROXY=http://10.121.8.110:8080",               "NO_PROXY=192.168.23.4"             ], 

After the file has edited, you only have to execute:

docker-machine provision  

Answer 2

With current docker machine version, I can't find better way to do the change as in boot2docker (Docker/Boot2Docker: Set HTTP/HTTPS proxies for docker on OS X)

If you manually set the proxy in /var/lib/boot2docker/profile in docker machine, after restart it, the proxy setting will be removed automatically.

So I have to create a docker machine with --engine-env set for proxy

docker-machine create -d virtualbox \     --engine-env HTTP_PROXY=http://example.com:8080 \     --engine-env HTTPS_PROXY=https://example.com:8080 \     --engine-env NO_PROXY=example2.com \     proxybox 

NOTES:

This is a two-years-old answer, there are a lot of changes happened in docker, so if you still can't make it work behind the proxy, please read @Senri's answer and others.
