auto enable disable poxy in VM

[olekhy]

I've working with Vagrant in two differ environment one is behind proxy and other without.

My problem is that the proxy values aren't removed from VM when my environment has not proxy.

What steps will reproduce the problem?

1. at office network that is behind the proxy after calling of vagrant up f.e. proxy values was written in VM. thats is ok. need to known that the proxy variables has been set by me previously.
2. at home my notebook were direct connected to the internet. also no proxy vars are present, after calling of vagrant up or vagrant provision proxy in VM was not removed.

how could be proxyconf used with the vagrant [up|provision] to achive that the proxy values will be removed from VM at my home?

I think this issue is the same as this one: https://github.com/tmatilai/vagrant-proxyconf/issues/38.

@olekhy Just to make sure we're clear. For your second point are you looking for the proxy to be removed from your laptop from an already running virtual machine/provisioning?

[olekhy]

So on HOST in termnal I'l enter:

$ env | grep -i proxy

and I'l get empty output that is because proxy is't set.

next I'l export proxy at enter

export HTTP_PROXY="http://myproxy:8080/"

and test this one by env | grep -i proxy all ok proxy value is present

my next step is starting of vagrant so I'l enter vagrant up anyway I've seen that the proxy value is provided to GUEST.

I'l check this one and login over vagrant ssh in to the GUEST, after entering of env | grep -i proxy I see proxy value identicaly with HOST are present.

Back to the HOST and unset proxy from environment

PROBLEM: after vagrant reload or (vagrant halt, vagrant up) and login into the GUEST I see that the proxy still there...

I would suggest the following pattern so that your Vagrantfile is easy to read. This also happens to be the most flexible in corporate environments.

Any idea how to do pick up the proxy settings on a windows host without installing extra apps such as these: http://msdn.microsoft.com/en-us/library/windows/desktop/aa384069(v=vs.85).aspx

[olekhy]

thx @johnbellone and made this addition:

vagrant.proxy.enabled = ENV.fetch('HTTP_PROXY', false)

that job for removing proxy value from VM fe. when I do vagrant up in env wo proxy?

@snowch hm I use unix also centos and ubuntu do not known windows, must I read article from MSDN anyway?

[snowch]

I set the http_proxy to DIRECT rather than disabling. Also, make sure you do an operation that triggers the setting change such as vagrant provision. You don't need to read the MDN article. On 24 Jan 2014 17:29, "Oleksandr" notifications@github.com wrote:

@olekhy vagrant.proxy.enabled is currently only in git, and not released yet. Until the release you can use something like:

config.proxy.http = ENV['HTTP_PROXY'] || ENV['http_proxy'] || false

@snowch note that 'DIRECT' only works for apt proxy configuration. For removing proxy settings in general, you should use fase (or empty string '').

So in general you can configure vagrant-proxyconf based on other environment variables, or use what ever ruby code to detect the environment. Verifying the configured proxy is coming on some point and is covered by #38. So I'm closing this now but feel free to keep commenting.
