Minecraft Server Using an Azure Virtual Machine

View Code

This example deploys an Azure Virtual Machine and provisions a Minecraft server.

Prerequisites

1. Install Pulumi
2. Configure Pulumi for Azure
3. Configure Pulumi for Python

Deploying and running the program

1. Create a new stack:

   $ pulumi stack init dev
   

2. Create a Python virtualenv, activate it, and install dependencies:

   This installs the dependent packages needed for our Pulumi program.

   $ python3 -m venv venv
   $ source venv/bin/activate
   $ pip3 install -r requirements.txt
   

3. Next, generate an OpenSSH keypair for use with your server.

   $ ssh-keygen -t rsa -f rsa -b 4096 -m PEM
   

   This will output two files, rsa and rsa.pub, in the current directory. Be sure not to commit these files!

   We must configure our stack and make the public key and private available to the virtual machine. The private key is used for subsequent SCP and SSH steps that will configure our server after it is stood up.

   $ cat rsa.pub | pulumi config set publicKey --
   $ cat rsa | pulumi config set privateKey --secret --
   

   Notice that we’ve used --secret for privateKey. This ensures the private key is stored as an encrypted Pulumi secret.

4. Set the required configuration for this example. This example requires you to supply a username, password, location, and the public and private keys to the virtual machine that we are going to create. Check the Azure virtual machine password requirements before creating a password.

   $ pulumi config set admin_password --secret <admin password>
   $ pulumi config set admin_username <admin username>
   $ pulumi config set azure-native:location westus # any valid Azure region will do
   

   Note that --secret ensures your password is encrypted safely.

5. Run pulumi up to preview and deploy the changes:

   $ pulumi up

6. Get the IP address of the newly-created instance from the stack’s outputs:

   $ pulumi stack output public_ip
   40.112.182.143
   

7. Check to see that your server is running by adding the server to the Minecraft client.

   

8. Destroy the stack:

   $ pulumi destroy
