Debugging container workloads can be a challenge sometimes, especially when running them in k8s, behind a reverse proxy or in other, possibly complex, traffic flow scenarios.
Thats what I built flask-tester for.
It is a Flask based app to inspect various aspects of the infrastructure surrounding the container it runs in.
It is available at registry.gitlab.com/mkamner/flask-tester:latest for direct use with any OCI compatible container runtime.
