how can i fixed it?

I found this link on another stack Overflow link, is it possible you are using an outdated version of Python? It was reportedly fixed 2019-07-22 according to python's bugs website

Gunicorn is failing with OSError: [Errno 107] Transport endpoint is not connected

I was facing this issue while running my application [Docker Image] with the gunicorn version 19.9.0 in Openshift. I'm not using the nginx to set [secure_scheme_headers]:https://github.com/benoitc/gunicorn/issues/1766.
Gunicorn Configuration

# Fix
I was able to fix the issue by shifting the older version of gunicorn==19.7.1
and gevent didn't work with the older version of the gunicorn.
https://github.com/benoitc/gunicorn/issues/1913

As mentioned in the comments, this is the same issue as #1993 and it is fixed in the pull request #2277. It is merged and available in the latest version of Gunicorn, version 20.1.0
So by updating to this version of Gunicorn, the problem is solved for me.

Connect to mysql server in a docker container from another docker container

In a nutshell
Using Dockers Desktop Community Version 2.0.0.3 (31259) in macOS Mojave I have two containers:
Alpine
MySQL
From the Alpine docker I am not be able to access the mysql server instance that is running on MySQL docker.
In details
On Alpine I am running python2 and python package mysqlclient. This is the configuration file that I use in my python application to access the mysql databases:
dbtype MySQLdb
connect-args {"user":"abe","db":"abe","passwd":"123"}
upgrade
host docker-mysql
port 32779
When I launch python application I see that it is unable to connect to mysqld server, in fact I get following error log:
python -m Abe.abe --config abe-my.conf
Reconnecting after rollback error: (2002, "Can't connect to local MySQL server through socket '/run/mysqld/mysqld.sock' (2)")
Reconnecting to database.

How it could be "fixed"?
I saw that the access file is /run/mysqld/mysqld.sock and I found it in the mysql docker, I suppose it should not be a problem to be able to connect the two dockers so that they "see each other", but at the moment I have no idea.

Flask Google Cloud App Engine: OSError: [Errno 98] Address already in use

I am trying to deploy a flask app on google cloud app engine. It runs smooth in my virtual environment locally but I get an 502 error running it in the cloud.
Now I am trying to debug my code on the cloud server, using debug mode and SSH into my instance. Using docker exec -it [ID] /bin/bash I am able to to access the root of my application. Now I upon running python app.py I get the following error:
* Serving Flask app "app" (lazy loading)
* Environment: production
WARNING: Do not use the development server in a production environment.

* Debug mode: off

OSError: [Errno 98] Address already in use
I've been trying to kill those processes listed when I run:
ps -fA | grep python
However, this does not solve the problem of the address being in use. Also changing the port in the app.run() does not solve the issue for me.

I had a similar problem, it was caused by the Flask app also being run when the module was loaded, because I had
if __name__ == "__main__":
app.run()
at the bottom. Note that the recent requirement to name your sever file "main.py" could cause this bug to emerge.

I think the problem is that you don't need to specialize the port for cloud. Google Cloud finds the port to run your app on its own. So instead of app.run(port=8080) just write app.run()

While I was not able to figure out how to "free" the running address, I solved the problem by starting another flask process by running it on a different port like so:
flask run --port=80

Your windows firewall may block python from listening.
Additionaly, try adding a different port number higher than 1024 to the command line and see if it helps.

I was not able to start since some service is already running on 8000,
I was able to successfully start the service on another port 2000
