🐾 Build steps

Pull the following 2 images first:
1. mendix/rootfs:bionic
2. mendix/rootfs:ubi8
Unzip docker-mendix-buildpack-offline.zip
Unzip and copy the content of cf-mendix-buildpack-4.15.4-offline.zip into the docker buildpack folder
Copy project directory into {docker-mendix-buildpack-offline}/project

<aside> ℹ️ You may remove the following folders from the copied project structure: deployment, data-snapshot.zip, any release folder containing .mda packages, and all the version control files (.git or .svn)

</aside>
Pre-download dependencies from mendix cdn
<aside> ☝ For mxbuild & mx runtime, you need to find out the exact build version of your Mendix Studio Pro used for your project.

</aside>
Put all 6 files into {docker_mendix_buildpack_dir}/dependencies
Then run:

$ docker build --build-arg BUILD_PATH="project" -f Dockerfile_offline --progress plain -t blank .

It's a 2-stage build, starting from a ubuntu:bionic , then finishing in a ubuntu:ubi8 image
After downloading 3 build phase dependencies (mono, mxbuild & jdk), the project is compiled and packaged in ubuntu:bionic image
Then 3 other runtime dependencies are downloaded (mxruntime, jre, & java keyutil)
The built project package and the runtime dependencies are copied into the 2nd ubuntu:ubi8 image, which is the final image
The first builder image is destroyed after the build
