production mode flask
To run a Flask application in production mode, follow these steps:
Set the
FLASK_ENV
environment variable to "production". This can be done by executing the following command in the terminal:export FLASK_ENV=production
.Specify the Flask application file using the
FLASK_APP
environment variable. For example, if your Flask application is stored in a file namedapp.py
, execute the following command:export FLASK_APP=app.py
.Run the Flask application by executing the command
flask run
. This will start the application in production mode.
By setting the FLASK_ENV
variable to "production", Flask will enable certain optimizations and configurations that are suitable for running the application in a production environment. Additionally, it may disable certain debugging features and enable better error handling.
Setting the FLASK_APP
variable allows Flask to locate and load the Flask application from the specified file. This ensures that Flask knows which application to run when the flask run
command is executed.
Running the flask run
command starts the Flask development server, which listens for incoming requests and serves the Flask application. In production mode, the server may use a different configuration than in development mode, such as using a different web server like Gunicorn or uWSGI.
It's important to note that running a Flask application in production mode may require additional configurations, such as setting up a web server or load balancer. These configurations may vary depending on the deployment environment and specific requirements of the application.
