From 001d06d7f6780797853503a2f278c49fbc6d8c5c Mon Sep 17 00:00:00 2001 From: Matthew Heon Date: Mon, 25 Nov 2019 19:00:11 -0500 Subject: Completely rework --change parsing The way we were trying to parse was very broken. I originally attempted to use Buildah's Dockerfile parser here, but dealing with it (and convincing it to accept only a limited subset, and only one instruction at a time) was challenging, so I rewrote a subset of Dockerfile parsing. This should handle most common cases well, though there are definitely unhandled edge cases for ENV and LABEL.
