Installing Unravel on cloud platforms using Ansible

You can install Unravel on Amazon EMR, Databricks (Azure, AWS), and Google cloud platform (Dataproc, BigQuery) using Ansible.

  1. Navigate to the ansible-installation directory and create a copy of the vars_template.yml file. 

    cp vars_template.yml vars.yml

  2. Edit vars.yml by using any editor. For example, the vi editor. 

    vi vars.yml

  3. Update the value for the cloud_platform parameter.

    # Update any required fields
# Must set cloud_platform=emr/dataproc/databricks

    The vars.yml file contains deployment parameters. You can customize these parameters for installing and deploying Unravel on cloud platforms.

  4. From the Unravel server, run the Ansible playbook.

    ansible-playbook -i inventories/ install_unravel.yml -e @vars.yml -vvv

    Applies all values specified in the vars.yml to the Ansible playbook. See Verify Unravel installation using Ansible.

  5. (Optional) Update the cloud_node inventory if you do not run the Ansible playbook from the Unravel server.

    Command

    vi inventories/cloud_node/hosts

    Output

    # Example hosts file
# [cloud_node]
# abc.unraveldata.com ansible_user=unravel ansible_ssh_private_key_file=/root/.ssh/id_rsa

  6. Specify the BigQuery configuration in Unravel. See Add BigQuery details in Unravel.

  7. Specify the path of a .txt file in the prop_file_paths variable. Ensure that the .txt file is readable by the Unravel user. 

    ansible-playbook -i inventories/ install_unravel.yml -e @vars.yml -vvv --tag hive_metastore
