Lab 2 - Imperative - Create VS, Pool and Members using seed file¶

You will create a consolidated playbook to deploy VS, Pools and associated Members.

Task 1 - Create consolidated playbook¶

Create a playbook appseed.yaml.

Type nano playbooks/app.yaml

Type the following into the playbooks/appseed.yaml file.

---

- name: "Imperative: Deploy / teardown a web app (VS, pool, nodes)"
  hosts: bigips
  gather_facts: False
  connection: local
  vars_files:
    - ../vars/appseedinfo.yaml

vars:
  state: "present"

environment: "{{ bigip_env }}"

tasks:
  - name: Adjust virtual server
    bigip_virtual_server:
      name: "{{ vsname }}"
      destination: "{{ vsip }}"
      port: "{{ vsport }}"
      description: "Web App"
      snat: "Automap"
      all_profiles:
        - "tcp-lan-optimized"
        - "clientssl"
        - "http"
        - "analytics"
      state: "{{ state }}"

  - name: Adjust a VS
    bigip_virtual_server:
      name: "{{ vs_name }}"
      destination: "{{ vs_ip }}"
      port: "{{ vs_port }}"
      snat: "{{ vs_snat }}"
      all_profiles:
        - "tcp-lan-optimized"
        - "http"
        - "analytics"
      state: "{{ state }}"

  - name: Adjust a pool
    bigip_pool:
      name: "{{ pl_name }}"
      monitors: "{{ pl_monitor }}"
      lb_method: "{{ pl_lb }}"
      state: "{{ state }}"

  - name: Add nodes
    bigip_node:
      name: "{{ item.name }}"
      host: "{{ item.host }}"
      state: "{{ state }}"
    loop:
      - { name: "{{ nd_ip1 }}", host: "{{ nd_ip1 }}" }
      - { name: "{{ nd_ip2 }}", host: "{{ nd_ip2 }}" }

  - name: Add nodes to pool
    bigip_pool_member:
      host: "{{ item.host }}"
      port: "{{ nd_port }}"
      pool: "{{ pl_name }}"
      state: "{{ state }}"
    loop:
      - { host: "{{ nd_ip1 }}" }
      - { host: "{{ nd_ip2 }}" }
    when: state == "present"

  - name: Update a VS
    bigip_virtual_server:
      name: "{{ vs_name }}"
      pool: "{{ pl_name }}"
      state: "{{ state }}"
    when: state == "present"

Ctrl-x to save file.

Run this playbook.
- Type ansible-playbook -e @creds.yaml --ask-vault-pass playbooks/appseed.yaml
Verify results in BIG-IP GUI.

Hint

You should see app3_vs deployed with 2 pool members. App should be accessible on http://10.1.10.30.
Run this playbook to teardown app.
- Type ansible-playbook -e @creds.yaml --ask-vault-pass playbooks/appseed.yaml -e state="absent"
Verify that app3_vs, pool and nodes should be deleted in BIG-IP GUI.

Note

This playbook leverages a config seed file in vars/appseedinfo.yaml. Simply modify this file to deploy a new service.
