My Python Flask App not deploying from GitHub

Questions / Help Build debugging
1

I’m trying to deploy my flask app from GitHub but it keeps erroring out.

I’m new to fly.io and this is my first time using GitHub workflows to deploy anything. I feel I’ve followed the examples and guides as close as I could.

My repo: GitHub - showipintbri/sid_checker: A web-app to display the raw rule/signature from the sid.

The last group of lines from GitHub actions output:

You can detach the terminal anytime without stopping the deployment
Monitoring Deployment

v36 is being deployed
4c8b85cf: iad running healthy
4c8b85cf: iad pending
4c8b85cf: iad pending
v36 failed - Failed due to unhealthy allocations - not rolling back to stable job version 36 as current job has same specification
Error abort
***v36 failed - Failed due to unhealthy allocations - not rolling back to stable job version 36 as current job has same specification and deploying as v37 



Troubleshooting guide at https://fly.io/docs/getting-started/troubleshooting/

When I run “flyctl logs” locally on my workstation while deploying I see output from my app’s “print” statements as well as errors.

Notable errors are:

This is the relevant error. Do you know what port your app is trying to bind to? It seems like it’s either trying to bind to one port a second time, or trying to bind to a port we “own” (port 22 is, I think, the only port we bind in your VM).

4

I was binding to port: tcp/8080.

5

I am only vaguely familiar with Python / Flask / gunicorn, but that makes it sound like two things are trying to bind to port 8080.

I found this on stack overflow, does it look relevant?

If you have Docker running locally, you can probably replicate this with something like:

docker build . -t my-flask-app
docker run --rm -p 8080:8080 my-flask-app
6

Nice find. I’ll play around with a few variations tonight and see if I can get it to launch properly. Thanks for the replies.

7

While I wasn’t running docker locally, I was running the straight python I was able to see why it was throwing this error.

Inside the python script I was invoking: app.run(host='0.0.0.0', port=8080) because I thought I had to to align with the fly.toml services stanza.

I understand now they were competing for each other.

I have re-worked how the fly.toml points to the internal service, and how the python script starts up.

I know have a fully deployed app from GitHub and it’s working and running on Fly.io (yay!)

However, now when I run flyctl logs I see critical worker timeouts and it’s constantly restarting my app. See the below logs. This happens every 30 seconds according to the timestamps:

Any ideas where I can get more info?

8

If you run fly vm status 698ae7cf you might see more information about what’s happening there (from our perspective). That WORKER TIMEOUT message isn’t coming from us, so it might be gunicorn producing it?

Those logs make it look like Python is logging an error and then exiting, then we restart, then it likely happens again.

9

I don’t see anything of importance here:

Oh, interesting. That means that the parent process isn’t actually exiting. So those logs are most likely gunicorn stopping and restarting child processes. I’m not actually sure what would cause that!

I’m looking up gunicorn log errors now. I might be able to get this resolved with a bit more research.

The gunicorn documentation says the timeout for workers in 30 seconds by default. This would explain why the workers were restarting every 30 seconds.

https://docs.gunicorn.org/en/stable/settings.html#timeout

I have my app up and running now without gunicorn in the Procfile.

The only reason I was using gunicorn was because it was mentioned in the example Python/Flask Fly.io guides.

I’ll keep digging, but for now I’m running straight flask no gunicorn.
