# Ruby stack overlay fragment.
#
# Layer this on top of huskies-project-base to produce a project container
# with Ruby, Bundler, and ruby-lsp (the Shopify Ruby language server).
#
# Build the combined image:
#   (echo "FROM huskies-project-base"; \
#    cat docker/stacks/ruby/Dockerfile.fragment) | \
#   docker build -t huskies-project-ruby -
#
# Adding a new stack: create docker/stacks/<name>/Dockerfile.fragment and
# docker/stacks/<name>/markers — no changes to orchestration code required.
