I want to run a flask application inside a docker container placed in a pod. I set the command of execution in deployment, but it just won’t work and continue to give me a feedback of crashloop back off. There are no logs available too.

But if I set the command to sleep infinity inside the deployment and run the command to execute the flask application manually with kubectl exec -it <pod name> --namespace <my namespace>, The application will work totally fine without erros.

The command to execute the flask application is

uwsgi --http <myurl:myport> --wsgi-file <my app file> --callable <my app name>

Can somebody help me with this issue? Thanks in advance!
