Dalli Development Container

This directory contains configuration for a development container that provides a consistent environment for working on Dalli.

Features

• Ruby 3.3+ environment with all necessary dependencies
• Memcached 1.6.34 installed with TLS support, matching the GitHub Actions CI environment
• VS Code extensions for Ruby development

Setup Process

When the container is built and started, the following setup occurs:

1. The container is built with necessary dependencies but without memcached
2. The setup.sh script runs after the container is created which:
   • Installs memcached 1.6.34 using the same script used in GitHub Actions
   • Sets up environment variables needed for tests
   • Installs gem dependencies

Running Tests

Once the container is running, you can run tests with:

bundle exec rake test

To run specific test files:

bundle exec ruby -Ilib:test test/path/to/test_file.rb

Troubleshooting

If you encounter issues with tests:

1. Verify memcached is running: ps aux | grep memcached
2. Check memcached version: memcached -h | head -1
3. Try restarting memcached: sudo service memcached restart
4. Check logs for any errors: sudo journalctl -u memcached

Port Forwarding

The following memcached ports are forwarded for testing:

• 11211 - Default memcached port
• 11212-11215 - Additional ports used by tests
