I’m developing an application using Next.js for the frontend and Rails for the backend. Initially, I was able to access the default pages provided by Rails and Next.js locally without any issues. However, after deploying my application to Fly.io using fly deploy, I encountered a problem where the machine repeatedly reboots and eventually moves into a suspended state.
I suspect the issue might be related to the differences between my development and production Dockerfiles. Here are the excerpts for reference:
- Dockerfile.dev(for development)
FROM ruby:3.2.2
WORKDIR /app
RUN apt-get update -qq && apt-get install -y build-essential default-mysql-client vim openssl ca-certificates
COPY Gemfile /app/Gemfile
COPY Gemfile.lock /app/Gemfile.lock
RUN gem install bundler
RUN bundle install
COPY . /app
COPY entrypoint.sh /usr/bin/
RUN chmod +x /usr/bin/entrypoint.sh
ENTRYPOINT ["entrypoint.sh"]
EXPOSE 3000
CMD ["rails", "server", "-b", "0.0.0.0"]
- Dockerfile(for production)
# syntax = docker/dockerfile:1
# Make sure RUBY_VERSION matches the Ruby version in .ruby-version and Gemfile
ARG RUBY_VERSION=3.2.2
FROM ruby:$RUBY_VERSION-slim as base
LABEL fly_launch_runtime="rails"
# Rails app lives here
WORKDIR /rails
# Set production environment
ENV BUNDLE_DEPLOYMENT="1" \
BUNDLE_PATH="/usr/local/bundle" \
BUNDLE_WITHOUT="development:test" \
RAILS_ENV="production"
# Update gems and bundler
RUN gem update --system --no-document && \
gem install -N bundler
# Throw-away build stage to reduce size of final image
FROM base as build
# Install packages needed to build gems
RUN apt-get update -qq && \
apt-get install --no-install-recommends -y build-essential default-libmysqlclient-dev
# Install application gems
COPY --link Gemfile Gemfile.lock ./
RUN bundle install && \
bundle exec bootsnap precompile --gemfile && \
rm -rf ~/.bundle/ "${BUNDLE_PATH}"/ruby/*/cache "${BUNDLE_PATH}"/ruby/*/bundler/gems/*/.git
# Copy application code
COPY --link . .
# Precompile bootsnap code for faster boot times
RUN bundle exec bootsnap precompile app/ lib/
# Final stage for app image
FROM base
# Install packages needed for deployment
RUN apt-get update -qq && \
apt-get install --no-install-recommends -y curl default-mysql-client openssl ca-certificates && \
rm -rf /var/lib/apt/lists /var/cache/apt/archives
# Copy built artifacts: gems, application
COPY --from=build "${BUNDLE_PATH}" "${BUNDLE_PATH}"
COPY --from=build /rails /rails
# Run and own only the runtime files as a non-root user for security
RUN groupadd --system --gid 1000 rails && \
useradd rails --uid 1000 --gid 1000 --create-home --shell /bin/bash && \
chown -R 1000:1000 db log storage tmp
USER 1000:1000
# Entrypoint prepares the database.
ENTRYPOINT ["/rails/bin/docker-entrypoint"]
# Start the server by default, this can be overwritten at runtime
EXPOSE 3000
CMD ["./bin/rails", "server"]
Additionally, I noticed bootsnap-related errors in the deployment logs, as shown below:
fetch: Operation not permitted - /usr/local/bundle/ruby/3.2.0/gems/bootsnap-1.18.0/lib/bootsnap/compile_cache/yaml.rb (Errno::EPERM)
In an attempt to resolve this, I modified the boot.rb file to include a custom cache directory, but the issue persists:
- boot.rb
Bootsnap.setup(
cache_dir: '/tmp/bootsnap',
development_mode: ENV['RAILS_ENV'] == 'development',
load_path_cache: true,
autoload_paths_cache: true,
compile_cache_iseq: true,
compile_cache_yaml: true
)
Here are the relevant parts of the logs from Fly.io:
