Dev Environment Supports More Project Types
@mattmanning is working hard on improving the convox development environment.
In this release, convox start has more smarts for projects with no Dockerfile / docker-compose.yml, and projects with a Procfile. Use convox update to update the CLI for these enhancements.
Thanks @prognostikos for contributions.
Rack Instance Count Validation
A rack requires at least 2 instances for:
- Running the rack API in a redundant fashion
- Spare capacity for a rolling deploy of a web process
- Service uptime or fast recovery when an instance dies.
So if you try running a rack with a single instance, strange side effects happen. Therefore we now prevent the ability to install or scale down a rack to a single instance.
Thanks to @markpundsack for a bug report, and @kmonkeyjam for a bug report and a patch!
Uninstall Robustness
Based on lots of feedback @nzoschke made convox uninstall much more robust. It now:
- Requires an explicit rack name and region preventing accidental rack deletion
- Deletes all services and apps automatically
- Retries deleting every service, app and rack to work around transient errors
- Empties and deletes S3 buckets
We hope that this makes Convox even easier to experiment with.
