"pongo run" failing with SSL error (macOS)

Am using Pongo for the first time, trying to do a basic “pongo run” test on some plugin code after installing it. However, I’m running into an error when pongo.sh is trying to build the test Docker image:

Step 15/18 : RUN apk update     && apk add zip unzip make g++ py-pip jq git bsd-compat-headers m4 openssl-dev curl wget python3-dev shadow     && curl -k -s -S -L https://github.com/fullstorydev/grpcurl/releases/download/v1.7.0/grpcurl_1.7.0_linux_x86_64.tar.gz | tar xz -C /kong/bin     && pip install httpie     ; cd /kong     && git config --global url.https://github.com/.insteadOf git://github.com/     && make dependencies     && luarocks install busted-htest     && luarocks install luacov

What I believe is happening is that the “apk update” command is failing because it is hitting the corporate web proxy which has a self-signed SSL cert which it doesn’t recognize.

I know there are ways to add the correct cert information but that involves editing the ./assets/Dockerfile that comes with the Pongo distribution. Wondering if there are other options which don’t involve changing the base Pongo code?
