I was always able to deploy until few days ago

------
production.Dockerfile:50
--------------------
  49 |     COPY Gemfile Gemfile.lock ./
  50 | >>> RUN bundle install && \
  51 | >>>     rm -rf ~/.bundle/ "${BUNDLE_PATH}"/ruby/*/cache "${BUNDLE_PATH}"/ruby/*/bundler/gems/*/.git && \
  52 | >>>     bundle exec bootsnap precompile --gemfile
  53 |     
--------------------
ERROR: failed to solve: process "/bin/sh -c bundle install &&     rm -rf ~/.bundle/ \"${BUNDLE_PATH}\"/ruby/*/cache \"${BUNDLE_PATH}\"/ruby/*/bundler/gems/*/.git &&     bundle exec bootsnap precompile --gemfile" did not complete successfully: exit code: 137

Exit code 137 : means out of memory from Docker

I have an Hetzner 2go ram

free -h

Mem:           1.9Gi       1.2Gi       102Mi        20Mi       544Mi       433Mi

I found another user on discord that also had an M2 (Apple Silicon) with Rosetta enabled. Adding multiarch fixes it

builder:
  dockerfile: production.Dockerfile
  multiarch: false # fixes 137 error out of memory
  remote:
    arch: amd64
    host: ssh://root@xxx.xxx.xxx.xxx
