Jenkins slave image not respecting NO_PROXY variable

Issue

Jenkins - based on FROM openshift/jenkins:2 and slave based on registry.access.redhat.com/openshift3/jenkins-slave-base-rhel7 does not work in proxy Environment.

We have set openshift proxy Settings - and those are available in Jenkins master env and slave env - as below.

no_proxy=.svc,.default,.local,localhost,.example.com,10.250.0.0/16,10.251.0.0/16,10.183.195.106,10.183.195.107,10.183.195.108,10.183.195.109,10.183.195.11,10.183.195.111,10.183.195.112,10.183.195.1
13,10.183.195.13,10.250.127.4
HTTP_PROXY=http://xxx:yyyyyzzzze@example.com:80 HTTPS_PROXY=http://xxx:yyyyyzzzze@example.com:80
However Jenkins slave Fails upon callback - and does NOT honor them - we also tried to set these in manage Jenkins / plugins / advanced - and they work - but are NOT passed to the slave

To me it looks like no_proxy is not used / not honored
