--https-proxy setting does not permit http:// URI

[ddisisto]

VIC version:

vic-machine-linux version v1.2.0-13652-9d146bc

Deployment details:

What was the vic-machine create command used to deploy the VCH? Yes

Steps to reproduce:

1. Have a proxy that only listens on http/8080, but is capable of proxying both http + https traffic
2. Attempt to configure that proxy for both --http-proxy + --https-proxy

Actual behavior:

ddisisto@neptune:~$ vic-machine-linux configure --id vm-172185 --https-proxy=http://proxy.gsoa.ddau:8080
Nov 15 2017 16:43:40.942+11:00 ERROR --------------------
Nov 15 2017 16:43:40.942+11:00 ERROR vic-machine-linux configure failed: Could not parse HTTPS proxy - expected format https://fqnd_or_ip:port: http://proxy.gsoa.ddau:8080

Expected behavior:

The configuration is updated

I've SSHd to the VCH VM in the hopes of finding where this is configured for the docker engine so that I could manually update it in-place until this is resolved. I have not been able to find it anywhere, and so remain unable to make any https connections from the docker engine.

@ddisisto I am a bit confused... you said it is only listening on http/80? but in your example you are doing port 8080?
Have you tried the --http-proxy option? Does that not give you what you want?

@mhagen-vmware My mistake, proxy is at http/8080 (fixed in initial comment now), which in docker and elsewhere in this environment I would always set as both HTTP_PROXY & HTTPS_PROXY. Setting only the --http-proxy does works fine, and maybe this is all that's needed for the docker engine to use proxy for both HTTP & HTTPS traffic, but I'm used to always just setting both to be sure.

To my knowledge, these two lines should both accept EITHER http or https schemes to be defined -

vic/cmd/vic-machine/common/proxy.go

Line 56 in d649a8a

if err != nil || hproxy.Host == "" || hproxy.Scheme != "http" {

vic/cmd/vic-machine/common/proxy.go

Line 64 in d649a8a

if err != nil || sproxy.Host == "" || sproxy.Scheme != "https" {

As the scheme used to connect to a proxy does not need to be the same as that of traffic that will be passed through it.

Thanks @ddisisto I am glad that using http-proxy seems to work for you! We will review your recommendation as you have suggested. Thanks!
