OpsCaptain can deploy Python apps written with any framework using the Cloud Foundry python-buildpack. From the developers perspective, you simply deploy your code using the CLI and OpsCaptain configures the environment to install dependencies using the buildpack and launch your application. If you are interested in understanding how the buildpack works and also specify a specific python version to run your app, review the buildpack docs using this link. OpsCaptain provides a Cloud Foundry compatible environment on your servers so you can run your Python applications effortlessly.
For a list of the supported Python versions, you can review the buildpack release notes found here
Install the opscaptain-cli on your local machine and also log in. If you haven't, run the below commands from your terminal to install it and login:
You must have already added the server that will be used to host your Python app. To add a server to your OpsCaptain account, follow this guide here.
From the dashboard: Log into the dashboard and create a new app using this link. Select the required database engine. If your app does not require a database, do not make a selection. Once the app and database are created, you can then proceed to deploy your code to it.
The Python buildpack does not generate a default start command for your applications. To stage with the Python buildpack and start an application, do one of the following:
Supply a Procfile. Create a file with name Procfile in the root directory of your application. The following example Procfile specifies gunicorn as the start command for a web app running on Gunicorn:
Another example starting your application with the python command:
You will typically configure the ocmanifest.json file on your first deployment or when you need to change any environment variables.
The below example shows a sample ocmanifest.json file to deploy Python apps:
CD into the project directory. Once there, run the below command to deploy and that's it.
