I am trying to deploy my django app in to production on a centos server. I have an app running on my computer(not server) with a code repository that doesn't utilize a virtual environment, and i wish i had set that up to begin with. I would like the production stage of the django app be run with a virtual environment, and was wondering what was the best way to go about this.
I am very cloudy on how this would work out. Would i need to set up the django app on my computer with a virtual environment, and then move the code repository to the server and go about it that way?
My understanding is the purpose of the virtual environment is to keep tabs and easily install any dependecies and software updates need to run the django app.
So the question is: Should i not worry about setting up a virtual environment on my computer, but start one on my server and start from there? Or would i run into problems when i try to git clone my project to the server because there isnt a virtualenv setup from the repository.
And if i should have it setup up on my local django app on my computer, how to i go about setting it up on an existing webapp?
The app doesn't care whether it's running in a virtualenv or not. You can simply create a new virtualenv on the server and redeploy the app inside it, reinstall the dependencies, then point your web server at the new app.

I created a website that uses vuejs as the frontend and django as the backend with another service running behind everything that im making api calls to.
So django is setup in a way to look at the dist folder of Vuejs and serve it if you run manage.py runserver. but the problem is that my service that I created is
is also in python and it needs to run in a virtualenv in order to work (It uses tensorflow 1.15.2 and this can only run in a contained environment)
I'm sitting here and wondering how I can deploy the django application and keep the virtualenv active and Im coming up with nothing, I've tried doing some research on this but everything I found was not relevant to my problem. I've deployed it and when I close the ssh connection the virtualenv stops.
If there is anyone that can enlighten my ways I would appreciate it.
i think you need to nginx: https://www.digitalocean.com/community/tutorials/how-to-set-up-django-with-postgres-nginx-and-gunicorn-on-ubuntu-16-04
if you are search for keep states just in terminal i suggest tmux https://github.com/tmux/tmux/wiki
You can use uWSGI and nginx to deploy Django apps on server. Here's helpful articles:

Django official docs also has a page about it: https://docs.djangoproject.com/en/3.1/howto/deployment/wsgi/uwsgi/
There are articles from developers so you can refer them in case you get stuck anywhere:

I am new in Django and this will be my very FIRST Times web deploying. So I am trying to deploy my project to the local server and My project stack is Django with MSSQL so obviously I will need Window.
I was read the documentation and I think I will need WSGI and As the documentation say to deploy with gunicron or uWSGI but both are supported for Unix and not for window. So How can I start this one? This will be the first question.
I would like to know whether I am doing is correct or not.
Now I copy my project to the local server and when I try to run my project like python manage.py runserver it asks me to install Django and other but I thought this environment is working at well my computer and all of the needed application is already installed in the environment. So I still need to install all of my needed apps like Django to this environment again?
If u have any tutorial or can guide me to some useful site, I will be very very appreciated.
Anything u want to know further, Just let me know.
Thanks.
I am creating a new Django project through PyCharm, I already have Virtualenv selected instead of conda, so do I have to create a virtual environment through the terminal and install all libraries? I am not planning to upload this site on domain or server, it's for my learning, will upload it on Heroku or similar thing to show my practice and work to people.
You don't have to install it again. Check in your PyCharm settings where the virtual environment has been installed, then all you have to do is:
. path/to/virtualenv/bin/activate
The question is in the title.
I need to deploy a Django application in a local network (i still don't know how to do but i suppose it's quite easy) but i still need to develop it. My question is how to do to allow users to use the application while i'm still developing it ?
Is it a solution to keep to versions of the application, one deployed and one in development ? In this way, I can replace the application deployed by the newly developed one when I finish coding it.
Another question concerns the database, can I still modify the database if I just add new models without touching existing ones ?
Thank you in advance,
This is a good blog entry that covers deploying Django using Heroku. I'll give you a quick rundown of what makes all the different technologies important:
Git
Git, or any other version control system, is certainly not required. Why it lends itself to deploying Django projects is that your usually distributing your application by source, i.e. your not compiling it or packaging it as an egg. Usually you'll organize your Git repository as such that updating your application on the server only requires you to do a checkout of the latest sources--nothing else.
virtualenv and pip
This, again, is not a strict requirement, but I'd strongly suggest you take the time to familiarize yourself with virtualenv and pip if you already haven't done so, since it's going to make deploying your Python applications across different runtime environments, local or remote, a breeze.
Basically, your project will need to have at least Django and Gunicorn available on the Python path, possibly even a database driver. What that means is that every time you try to deploy your application somewhere you'll have to install Python and do the easy_install dance all over.
virtualenv will redistribute a Python installation, which in turn means that the new Python instance will, by default, have it's very own Python path configuration relative to the installation. pip is like easy_install on steroids, since it supports checking out Python dependencies directly from code repositories and supports a requirements file format with which you can install and configure all of your dependencies in one fell swoop.
With virtualenv and pip, all you'd need to do is have a simple text file with all your dependencies that can be parsed with pip and an installed Python distribution on the machine. From there you just do git checkout repo /app/path; easy_install virtualenv; virtualenv /app/path; ./app/path/scripts/activate; pip install -r /app/path/requirements.txt. Voila, Gunicorn, Django and all other dependencies are then installed and available immediately. When you run the Gunicorn Django script with the Python instance in /app/path/scripts, then the script will immediately have access to the Gunicorn sources and it will be able to locate your Django project which will have access to Django and other dependencies as well.
Gunicorn
This is the actual Python application that will manage your Django instance and provide an HTTP interface that exposes it to HTTP clients. It'll start several worker processes which will all be distinct Python virtual machines loaded with the sources of your application and it's dependencies. The main Gunicorn process will in turn take charge of managing which worker processes manage which requests for maximum throughput.
The basic principle of wiring Nginx and Gunicorn
The most important thing to observe is that Nginx and Gunicorn are separate processes that you manage independently.
The Nginx Web server will be publicly exposed, i.e. it will be directly accessible over the internet. For requests to static media, such as actual images, CSS stylesheets, JavaScript sources and PDF files accessible via the filesystem, Nginx will take charge of returning them in the response body to HTTP clients if you configure it to look for files on the path where you configured your project to collect static media.
Any other request should be proxied to your Gunicorn instance. It will be configured to listen to HTTP requests on a certain port on the loopback interface, so you'll using Nginx as a revers proxy to http://127.0.0.1:8080 for requests to your Django instance.
This is the basic rundown for deploying your Django projects into production that should satisfy the needs of 95% Django projects running out there. While I did reference Nginx and Gunicorn, it's the usual approach when it comes to setting up any Web server to act as a reverse-proxy to a Python WSGI server.
I'm attempting to deploy a Django app via docker, first locally, and then to a cloud server. I could not find an answer to my initial question before I attempt this: if I run docker-machine create, I'm guessing this should be run from within my virtualenv, right?
This would then grab all of my specific app dependencies, and begin to build certificates to throw in the container? If not, please explain otherwise..
Yes you are correct.
I will try to help you by my experience, if you wanna deploy django apps via docker.
First you need to setup docker machine in your local machine. Please see the
instruction. By default driver that will be used is --driver
virtualbox default.
List what kind of specifics dependencies images of your apps. Ex:
you need nginx, postgres, uwsgi, or you need to fetch an image then
modified that image you can use dockerfile (its the best practice
for you).
I suggested you to use docker-compose. Really its make our project
pretty easy to manage. You have to define all images that you need
for your app in docker-compose file Please read this reference.
After you finished develop your app then you want to deploy in production server (cloud) you just need to copy all your project then running your docker-compose. All images dependencies will be automatically pulled in the cloud.
As a reference, you can see this project (this is an open source project that I developed.) On that project, I use make file to manage docker-compose command and it make easy to manage.
An example of dockerfile
An example of docker-compose.yml
An example of Makefile
Hope this will help you.
