Bug 1821861

Summary: [4.3] Build incorrectly substitutes "=" for spaces in Dockerfiles

Hardware: Unspecified

Fixed In Version: Doc Type: Bug Fix
Doc Text:
Cause: Before starting a build, the OpenShift builder would parse the supplied Dockerfile and reconstruct a modified version of it to use for the build, to add labels and handle substitutions of the images named in FROM instructions. The generated Dockerfile did not always correctly reconstruct ENV and LABEL instructions. Consequence: The generated Dockerfile would sometimes include "=" characters where the original did not, and the build would fail with a syntax error. Fix: When generating the modified Dockerfile, the original text for ENV and LABEL instructions is now used verbatim. Result: The build process should no longer introduce syntax errors in ENV and LABEL instructions.

+++ This bug was initially created as a clone of Bug #1821858 +++

Description of problem:

When rewriting the Dockerfile with our substitutions, we unconditionally insert = characters, even in cases where the original file didn't use them. They're syntactically important, though, so such changes can cause builds to fail. For ENV and LABEL instructions, just emit the original text.

Reported in openshift/origin#24151 [1]. Fixed by openshift/builder#134 [2]

Version-Release number of selected component (if applicable): 4.2.z

How reproducible: Always

Steps to Reproduce:

1. Create Docker fbuild from e.g.
   git url: https://github.com/sonatype/docker-nexus.git
   context dir: /oss
2. Start build

Actual results:
