🎉 Release 0.4.0-beta: Share Your Feedback! 🚀

I'm excited to announce the 0.4.0-beta release of Ofelia, which includes some significant updates based on recent pull requests:

• Dynamic docker labels handling #319

which is based on the original PR from @rdelcorro (thanks a lot for the initial implementation):

• Handle config changes on docker updates #137

Now Ofelia will watch for any new containers running in you're environment (use -f flag to provide docker filter expression) and dynamically register new jobs configured via docker labels (see jobs.md for example label configurations).

💬 How You Can Help:

• Test out the 0.4.0-beta release in your environment.
• Share your feedback on the newly implemented features.
• Report any issues found

TODO

• Add integration tests for config.ini style configurations.
• Replace github.com/op/go-logging with https://pkg.go.dev/log/slog
• Update documentation
• Add more tests for global configurations
• Add tests for mixed configurations (config.ini and docker labels)
