Flask with MongoDB and PostgreSQL (MS3) : Settings

To ensure the application is configured correctly, the web service's configuration settings are required.


A brief explanation of each setting is given below.

Settings

Name

A name is chosen to help identify the deployment. This will be listed in the Render dashboard overview.

The name chosen will form part of the deployed URL. If the name is unique on Render.com, the resulting URL will be <name>.onrender.com. If the name is not unique, a random hash with be appended to the name given, e.g. <name>-3yk1.onrender.com

Root Directory

The root directory of the project and its content. This can be edited if required, but usually it will remain blank, thus indicating the root directory of the repository is the same as the root directory of the web service.

Environment

The nature of the program so Render.com knows which of their configurations to use. With Python selected, Render will use their latest specified default Python version, but this is configurable.

Region

The physical location of the server hosting the web service. The location will slightly effect loading speeds etc.

Branch

The branch that the service should be deployed from. This will often be main (or master for older repositories) but is configurable to any public branch within the repository.

Build Command

This is the command that is executed when the deployment build is initiated. The command instructs the build to install the pip packages from the requirements.txt file.

Start Command

This is the executable command that is run once the build has completed. When the build process is completed, the created environment runs this command just as you would have done during development.
