A demo project for showing off DevOps tools and processes like GitHub Actions and Dependabot alerts.

Note that this repository has dependencies with known security vulnerabilities, which is purposeful to show off things like GitHub Security Advisories.

Activate the python venv by running venv\Scripts\activate.bat. To install the required python packages using the requirements.txt, run pip install -r requirements.txt

If changes are made to the models, run python manage.py makemigrations to generate any required database migrations, and then python manage.py migrate to apply.

Huey is used as a multi-threaded task queue for tasks such as generating charts or fetching weather data without blocking the web application thread. Redis is used as the message broker between threads.

To install redis on windows, activate WSL by running the following in an elevated Powershell prompt Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux

After rebooting, install Ubuntu from the Microsoft Store.

Next, launch bash for windows and install build-essential and tcl using sudo apt-get install build-essential tcl8.5

Now that we have the required packages to install redis, run wget download.redis.io/releases/redis-5.0.0.tar.gz to download a compressed version of redis, and tar xzf redis-5.0.0.tar.gz to uncompress it. cd into the newly uncompressed directory and compile redis into a binary by running sudo make distclean and sudo make -j.

Copy the compiled binary over to /usr/local/bin by running sudo make install -j. Next, cd into the utils folder and run sudo ./install_server.sh to run the installation script. This will create a service for our redis server.

To start the redis service, run sudo service redis_6379 start, and sudo service redis_6379 stop to stop the service.

If the redis service is running, executing python manage.py run_huey from our venv will start huey and connect it to our redis service.
