Role Variables

This role is designed for standalone provisioning by default. For distributed provisioning, you can add more nodes with a proper naming format in your YAML file.

In defaults/main.yml, you can specify:

# GCP project
general:
    project: sandbox-236618       # GCP project ID 
    region: europe-west4          # GCP region
    auth_kind: serviceaccount     
    service_account_file: ~/.ssh/ansible.json
scopes:
    - https://www.googleapis.com/auth/compute

# design your infrastructure architecture
nodes:
  - name: standalone-node    # Example node names: standalone-node, name-node, data-node1, etc.
    zone: europe-west4-a     # Choose nearby zones and distribute other nodes accordingly
    machine_type: f1-micro   # Upgrade if necessary
    ips:
        - nic: 
            name: "ip-01"
    tags: hadoop             # Tags used by firewall rules (use tool names like hadoop or elasticsearch)
    labels:                  # Filtering! Use tool names as type and master/worker for identification
        type: hdfs
        name: master
    boot_disk:
        - disk:
            name: "boot-disk-01"
            size: 100
            image: "projects/ubuntu-os-cloud/global/images/family/ubuntu-2004-lts"
            auto_delete: true
            boot: true
    additional_disks:
        - disk: 
            name: "data-disk-01"
            size: 300
            auto_delete: true     # Set to false for production environments
            boot: false
        - disk: 
            name: "log-disk-01"
            size: 300
            auto_delete: true     # Set to false for production environments
