Deploy Scaleway Servers via the API in Python

A quick post on how to deploy Scaleway Servers via their API using Python.

API Documentation

Scaleway has great API Documentation available, so for deeper info have a look at the link provided.

Python

Our python script has a function create_server that expects a server name, server size, the tag and the linux distribution:
