How to Package and Deploy FerretDB with Acorn
In this blog post, we will explore how to build, package, and deploy a Python application that uses a FerretDB database with Acorn.
FerretDB is an open-source document database alternative for MongoDB that provides PostgreSQL or SQLite as database backend options. This means you can use FerretDB for production environments without worrying about vendor lock-in. And by using Acorn, you can easily make deployments easier.
Acorn is a simplified Kubernetes-based application deployment framework for developers and software engineers. Suppose you have a Python application with FerretDB as the database; you can easily deploy it using Acorn.
With Acorn, you have a fully managed development platform for running cloud-native applications. It provides a layer of abstraction on top of Kubernetes, so there's no need to interact with Kubernetes YAML files directly. Instead, Acorn provides application-level constructs such as Docker containers, app configurations, and deployment specifications.
Let's get into it.
Prerequisites
We will set up a Python application with FerretDB as the database and deploy it with Acorn. This blog post is adapted from the Acorn setup guide for a MySQL database.
For the guide, we'll need the following:
- Acorn CLI (GitHub account to sign up for the Acorn platform)
Installing Acorn
First, we need to install the Acorn CLI.
This will enable us to run acorn
commands directly from our CLI.
For macOS & Linux, run this command.
brew install acorn-io/cli/acorn
For Windows, download the CLI from this URL:
scoop install acorn
Once Acorn is installed, log in via your GitHub account by running:
acorn Login
You will be prompted to create an Acorn account using your GitHub account. Once logged in, return to the terminal.
Setting up the Python Application
We will start by setting up a simple todo Python Flask Application that connects with FerretDB, which uses an AWS RDS for PostgreSQL as the backend.
Let's create the directory for the project:
mkdir -p my-ferret/templates
cd my-todo
touch app.py requirements.txt templates/template.html Dockerfile Acornfile
Here, we've created the app.py
file that will contain our python application.
The structure of the directory should look like this.
my-ferret/
