Deploy a Python Application to Oracle Cloud

Before You Begin

This 10-minute tutorial shows you how to deploy a Python application to Oracle Application Container Cloud Service.

Background

Oracle Application Container Cloud Service lets you deploy Java SE, Java EE, Node.js, PHP, Ruby, Go, .Net Core, and Python applications to the Oracle Cloud.

What Do You Need?

An Oracle Cloud account with access to Oracle Application Container Cloud Service

Create a Python Application

Create the python-app project directory in your local system.

In the python-app directory, create the app.py file and add the following content:

#!/usr/bin/python
import os
from http.server import BaseHTTPRequestHandler, HTTPServer
PORT_NUMBER = int(os.environ.get('PORT', 8084))

# HTTPRequestHandler class
class testHTTPServer_RequestHandler(BaseHTTPRequestHandler):
 
  # GET
  def do_HEAD(self):
        # Send response status code
        self.send_response(200)
        self.send_header('Content-type', 'text/html')
        self.end_headers()
        return
  # GET
  def do_GET(self):
        # Send response status code
        self.send_response(200)
 
        # Send headers
        self.send_header('Content-type','text/html')
        self.end_headers()
 
        # Send message back to client
        message = "Hello world!"
        # Write content as utf-8 data
        self.wfile.write(bytes(message, "utf8"))
        return
 
def run():
  print('starting server...')
 
  # Server settings
  # Choose port 8080, for port 80, which is normally used for a http server, you need root access
  server_address = ('0.0.0.0', PORT_NUMBER)
  httpd = HTTPServer(server_address, testHTTPServer_RequestHandler)
  print('running server...')
  httpd.serve_forever()
  
run()

Prepare the Application for Deployment

In the python-app directory, create the manifest.json file and add the following content:
```
{
  "runtime": {
    "majorVersion": "3.6.0"
  },
  "command": "python app.py",
  "notes": "Simple REST Service"
} 
```
Open a command-line (or Terminal in Linux), go to the python-app directory, and compress the manifest.json file and the app.py file together in a .zip file.
```
zip python-app.zip app.py manifest.json 
```

Deploy Your Application to Oracle Application Container Cloud Service

Open the Oracle Application Container Cloud Service console.
In the Applications list view, click Create Application and select Python.
In the Application section, enter a name for your application and click Browse.
On the File Upload dialog box, select the python-app.zip file you created in the previous section and click Open.
Keep the default values in the Instances and Memory fields and click Create.
Wait until the application is created. The URL is enabled when the creation is completed.
Click the URL of your application.
