Deploy NodeJS & Python3 applications on an Oracle Cloud Compute instance

DinoDate

DinoDate currently has both Python and NodeJS mid-tier applications and is backed by an Oracle Database.

The following instructions show how to deploy DinoDate to an Oracle Cloud Compute instance.  However, if you just need to deploy a NodeJS or Python application, the same instructions should help you install Node and/or Python 3.

If you don’t have access to an Oracle Database you can try the Oracle Cloud for free.

Database

Download/Clone DinoDate to get the database scripts you’ll need.

Create an Oracle Cloud database.

Connect to your database as sys with sysdba and run coreDatabase/dd_master_install.sql.  (Use your password and connect string)

Compute

Create an Oracle Cloud Compute instance.

Open the ports for our NodeJS and Python apps.

Download and scp the following to your new compute instance.  (Current versions as of the time of this post.)

Open an ssh connection to your compute instance.  (Use your ssh key and the public IP address for your compute instance)

  • Switch to su
  • Update your instance
  • Install some tools we’ll need

Install both Oracle Instant Client files

Install NodeJS 8

  • Install some tools we’ll need
  • Enable the config manager
  • Install Python 3.5
  • Enable Python 3.5
  • Upgrade pip
  • Install the python modules for DinoDate
    • cx_Oracle
    • bottle
  • Exit scl bash:

Exit su

Add the following to your .bash_profile:

  • Create the environment variables  for DinoDate (use the JDBC connect string for your database)
  • Enable Python 3.5.
Re-run .bash_profile
  • Clone DinoDate to your Compute instance
  • Extract the Oracle JET files
  • Run bower install
  • Install the NodeJS modules
  • Use pm2 to start the NodeJS version of DinoDate
    The –watch parameter will restart the application if the files change.
  • (We already installed the Python modules above)
  • Use pm2 to start the NodeJS version of DinoDate
    The –watch parameter will restart the application if the files change.
‘pm2 startup’ will generate the command needed to restart our applications on boot.  The following will extract and execute the command from the generated text.

Try it out

Open a browser and pull up DinoDate:

  • NodeJS
    http://YourComputePublicIP:3000
  • Python
    http://YourComputePublicIP:8088

You can log in with any of the existing users, such as:

  • Bob
    bob@example.com
  • Admin
    admin@example.com

Use any value for the password, the application doesn’t check it.

Click on the Search tab and search for ‘eat’ it should return 6 of the pre-loaded dinosaurs.
