Gathering facts from file

Variables from an Oracle response file

This snippet gets some variables from the response file and puts them into an environment variable oracle_environment and sets the variable name itself (prepended with oracle_ if not already there). The variable oracle_environment can be used for environment: when you use shell:.

  vars:
    oracle_user:          oracle
    oracle_version:       12cR2 
    oracle_response_file: /install/tepmplate_{{ oracle_version }}/db_{{ oracle_version | lower}}.rsp

  - name: "Getting variables for version {{ oracle_version }} from response file"
    shell: |
      awk -F '=' '/{{ item }}/{print $2;}' {{ oracle_response_file }}
    register: oracle_response_variables
    with_items:
      - ORACLE_HOME
      - ORACLE_BASE
      - INVENTORY_LOCATION
    tags:
      - oracle
      - oracle_install

  - name: Setting facts from response file to oracle_environment
    set_fact:
      "{{ 'oracle_' + item.item | lower | regex_replace('oracle_','') }}": "{{ item.stdout }}"
      oracle_environment: "{{oracle_environment|default([]) + [ {item.item: item.stdout} ] }}"
    with_items:
      - "{{ oracle_response_variables.results }}"
    tags:
      - oracle
      - oracle_install
