Chapter 7 Tactical Playbooks

Now prompt for a file name, “PRE-CHANGE” for the output for the show ip ospf neighbor command. Execute the changes, and then prompt for another file name “POST-CHANGE”. Recapture the show ip ospf neighbor command.

First create a YAML file called ospfneighbor_prompt.yml and add the following lines: 
 
--- 
 
   - name: run show ospf neighbors 
     ios_command: 
       commands: show ip ospf neighbor 
       provider: "{{ ioscli }}" 
     register: ospfneighbor_result 
 
   - set_fact: ospfneighbor={{ ospfneighbor_result.stdout_lines | to_nice_yaml }} 
 
   - name: create log file for all devices 
     file: path=./results/{{ output_file }}.all.txt state=touch 
     check_mode: no 
 
   - name: log to file for all devices 
     lineinfile: 
       insertafter: EOF 
       path: ./results/{{ output_file }}.all.txt 
       line: '{{ item }}' 
     with_items: 
       - "#####{{inventory_hostname}}#####" 
       - "{{ ospfneighbor }}" 
     check_mode: no 
 
   - name: create log file for individual device 
     file: path=./results/{{ output_file }}.{{inventory_hostname}}.txt state=touch 
     check_mode: no 
 
   - name: log to file for individual device 
     lineinfile: 
       insertafter: EOF 
       path: ./results/{{ output_file }}.{{inventory_hostname}}.txt 
       line: '{{ item }}' 
     with_items: 
       - "#####{{inventory_hostname}}#####" 
       - "{{ ospfneighbor }}" 
     check_mode: no 
 
Next, create the executable playbook. Prompt for a file name, execute the playbook / changes, then be 
prompted again for another file name for the post-change output. Create a YAML file called 
ospf_point_to_point.yml and add the following lines:

--- 
 
- hosts: CAMPUS 
  serial: 1  
  vars_prompt: 
   - name: output_file
