Fail at #18 Buildpack Mono.py

[SamRhodesSiemens]

Hi,

I am trying to build an image from Mendix Buildpack, but sadly ran into a few errors. I previously managed to containerize except that it managed to containerize the sql database but not the mendix buildpack. I shut down VM, and then when opened, re-ran, now have following build issue at stage 18 with it not finding mono.py

docker build
--build-arg BUILD_PATH=build
--build-arg CF_BUILDPACK=v4.17.1
--build-arg ROOTFS_IMAGE=mendix/rootfs:ubi8

I was having the same issue, so I took a look at the source code of cf-mendix-buildpack and I found a solution :

In the Dockerfile, set a default value for BLOBSTORE.

    ARG BLOBSTORE=https://cdn.mendix.com

remark : in cf-mendix-buildpack code, if BLOBSTORE is not define, the value "https://cdn.mendix.com" is used instead. That's why I use this value. But it looks like there is an issue in cf-mendix-buildpack, and the default value is not used when BLOBSTORE has not default value in the Dockerfile :

    ARG BLOBSTORE
