Description Manikandan Somasundaram 2018-04-12 13:43:22 UTC
Description of problem:
  When deploying an application using the provided S2I images the environment variables "http_proxy", "https_proxy" and "no_proxy" are built into the container image.  Container images should not contain proxy related env variables.

Version-Release number of selected component (if applicable):

* OpenShift Container Platform 3.x

Steps to Reproduce:

1] Create deployment config with "http_proxy", "https_proxy" and "no_proxy" in “/etc/origin/master/master-config.yaml” file
2] Deploy an application and observe that the proxy environment variables gets injected in to an application container. 

Actual results: 
-  Proxy environment variables injects in to an application container.

Expected results:
- Proxy environment variables should inject in to build pod and once build gets completed the variables should not injected in to an application container.

Additional info:

Comment 1 Ben Parees 2018-04-12 13:50:08 UTC
Unfortunately there's nothing we can do about this, it's a limitation of the architecture of s2i which has to provide the env vars to the container running your assemble script (so your assemble logic has a proper proxy configuration), and then commits that container as your new image.


The behavior is documented:

https://docs.openshift.org/latest/dev_guide/builds/build_strategies.html#configuring-the-source-environment

"Variables provided will be present during the build process and in the output image."
