LAB 05 - Manage Containers on CloudVision

About

Create and update containers on CloudVision

Execute lab

1. Review containers vars

# Go to lab05 directory
$ cd ../lab05-cv-containers

$ cat group_vars/CVP.yml

---
CVP_CONTAINERS:
  TRAINING:
    parent_container: Tenant
  TRAINING_DC:
    parent_container: TRAINING
  TRAINING_LEAFS:
    parent_container: TRAINING_DC
  TRAINING_SPINES:
    parent_container: TRAINING_DC
    devices:
      - 'spine1'

2. Create containers and move device

# Run playbook to create containers and move device
$ ansible-playbook playbook.container.yml

On cloudvision server, cancel task and move back device to its initial container

3. Optional: Attach 01TRAINING-01 to TRAINING container

Edit CVP.yml file

# Attach 01TRAINING-01 to TRAINING container and remove Spine1 under the container TRAINING_SPINES
$ vi group_vars/CVP.yml

And update content with the following:

---
CVP_CONFIGLETS:
  01TRAINING-alias: "alias a{{ 999 | random }} show version"
  01TRAINING-01: "alias a{{ 999 | random }} show version"

CVP_CONTAINERS:
  TRAINING:
    parent_container: Tenant
    configlets:
      - '01TRAINING-01'
  TRAINING_DC:
    parent_container: TRAINING
  TRAINING_LEAFS:
    parent_container: TRAINING_DC
  TRAINING_SPINES:
    parent_container: TRAINING_DC

# Run playbook to attach the configlet to the container
$ ansible-playbook playbook.container.yml

It will fail. Why does it fail? How can you solve the issue? Hint: is the configlet that you are trying to attach to the container present on CloudVision?

4. Remove Container topology

# Edit playbook and change mode to `delete`
$ vi playbook.container.yml

- name: "Configure containers on {{inventory_hostname}}"
  arista.cvp.cv_container:
    cvp_facts: "{{CVP_FACTS.ansible_facts}}"
    topology: "{{CVP_CONTAINERS}}"
    mode: delete
    register: CVP_CONTAINERS_RESULT

# Run playbook to delete containers
$ ansible-playbook playbook.container.yml

Then check on CloudVision
