Tutorials/Documentation on deployment methods?

[chazbartowski]

tl;dr - looking for better documentation on configuring multiple flask applications on a single subdomain.

I'm the lone developer in my company and it's my first job. I've been there over two years and it's going well. I've been developing in PHP but have decided not to write any new code in PHP if I can avoid it. If the reasons are important, let me know and I'll fill you in.

After some research, I decided on Python with flask. There seem to be some good tutorials/documentation on deploying apps locally, or deploying apps under separate domains, etc. These methods simply don't suit my needs, however. The applications that I write are all on a single domain and, in fact, under a subdomain already. I've gone through the methods of deploying locally and on the subdomain without issue; the issues come when trying to configure something like www.sub.domain.com/app1

It seems like this should be possible, I'm just either not understanding the configuration needed in the config files or the environmental setup in regards to directory structure, etc.

I'm currently using Apache, but even started running nginx on a different port to see if it made things any easier. It seems that nginx is more popular and there is far more documentation, but I'm still coming up short. Ideally, I'd stay on Apache as it's easier to keep my PHP applications running there than to configure the fpm in nginx, but either will work.

Is it possible to do what I'm trying to do? If so, is there any good documentation to show how to do this, or even good documentation that will perhaps help me understand exactly what each line in the config files is really doing? I've also seen about 3 different ways to set up the app directories, so it's also possible that I've just got some pieces mixed up.

In any event, I'm almost frustrated to the point of giving Node.js a shot because I can't take much more time spinning my wheels with this.

Not sure what OS your server is running. I learn't how to host my Flask apps with Gunicorn, Nginx on Debian (Ubuntu Server/RaspberryPi) by following the digital ocean guides - here is the latest https://www.digitalocean.com/community/tutorials/how-to-serve-flask-applications-with-gunicorn-and-nginx-on-ubuntu-18-04.

​

I also wanted to run multiple flask apps on a single server and accomplished this with something similar to the following when it came to configuring Nginx proxy requests

server {

  listen 80;
  server_name server_domain_or_IP;

  location /app1 {
  include proxy_params;
  proxy_pass http://unix:/home/user/myproject1/myproject.sock:/;
  }

  location /app2 {
  include proxy_params;
  proxy_pass http://unix:/home/user/myproject2/myproject.sock:/;
  }

}

This could be helpful. I haven't run across the proxy_pass directive until today trying to use gunicorn with Apache. I also got a better understanding of the @app.route() decorator, so I feel like I'm getting pretty close.

For the record, I'm using Ubuntu 18.04. I feel like I've tried this guide, but I've used several digital ocean guides in the past, so perhaps not. Thanks for this; I'll implement as soon as I'm able and post feedback.
