Subscribie Deployer

Standalone starlette app which receives a new site build request, and builds the site. (ref Subscribie/module-builder#7)

Responsible for building new subscribie sites.

• When a new site is created (via /start-building), all data needed to build the site is sent (as json) to this endpoint which then builds a new subscribie site
• Site settings are in an .env file
• Each site runes in its own isolates process (using uwisgi), using the same subscribie repo
  • Note Each site runs independently with its own database, but the codebase is not duplicated.
  • This is different from a previous implementation which cloned the Subscribie repo for each new site.
• Each site runs as a uwsgi 'vassal' which allows new sites to come online without having to restart the web server

Configuration

Create virtual env & install requirements:

virtualenv -p python3 venv . venv/bin/activate pip install -r requirements.txt

• Copy .env.example to .env
  • Edit SITES_DIRECTORY to directory where to deploy sites to
  • And all other env settings

For running locally in development: ./run.sh

Speed improvements

• Clone subscribie to a folder on a deployment server. Set SUBSCRIBIE_REPO_DIRECTORY to the repo folder.

• Create a virtualenv folder and set to PYTHON_VENV_DIRECTORY, pip install the requirements.txt

• Go into the subscribie shared repo, and create a database schema using flask db upgrade inside PYTHON_VENV_DIRECTORY

  • Copy .env.example to .env and set SQLALCHEMY_DATABASE_URI to SUBSCRIBIE_REPO_DIRECTORY root (the empty schema is copied to new sites to speed up new site deployments

• Back into this repo (deployer) Set PYTHON_PATH_INJECT to the same value as SUBSCRIBIE_REPO_DIRECTORY

UWSGI notes

How to run:

uwsgi --ini config.ini # add -d to demonize

Ensure that dir /tmp/sockets/ exists (for the vassal sites .ini files)

Then chmod /tmp/sock1 (todo fix this using chmod uwsgi flag)

Example Nginx Config (deployer)

# mysite_nginx.conf
#

# configuration of the server
server {
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name *.app1 example.com ~^.*.example.com app2 site1.local site2.local; # substitute your machine's IP address or FQDN
    root /home/chris/Documents/python/uwsgi/vassals/;
    charset     utf-8;

    client_max_body_size 75M;

    # max upload size

    location / {
        proxy_pass http://127.0.0.1:8002/;
    }
}

Apache config example (deployer)

(Using ip rather than sockets)

<VirtualHost *:80>

  ServerAdmin webmaster@localhost
  DocumentRoot /var/www/html

  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined

  ServerName example.com
  ServerAlias *.example.com
  ProxyPass / http://127.0.0.1:8002/

</VirtualHost>

Test

curl http://127.0.0.1:5001/ -d '{"company": {"name": "My Test Shop"}, "users": ["sam@example.com"], "password": "123", "plans": [{"title": "Hair Gel", "description": "Luxuary hair gel", "interval_amount": 100, "interval_unit": "monthly", "sell_price": 1500}]}'
