Hello,
i can't build the Dockerfile on : RUN stack build => The command '/bin/sh -c stack build' returned a non-zero code: 137

Hi @Tarektouati,

Can you try to follow the instruction in the Dockerfile (ie. run with -j1)?

# NOTE:`stack build` will use as many cores as are available to build
# in parallel. However, this can cause OOM issues as the linking step
# in GHC can be expensive. If the build fails, try specifying the
# '-j1' flag to force the build to run sequentially.

It looks like it should help with out-of-memory issues.
