Ansible Collection - cisco.dnac

Ansible Modules for DNA Center

The dnacenter-ansible project provides an Ansible collection for managing and automating your Cisco DNA Center environment. It consists of a set of modules and roles for performing tasks related to DNA Center.

This collection has been tested and supports Cisco DNA Center 2.3.7.6.

Note: This collection is not compatible with versions of Ansible before v2.8.

Other versions of this collection have support for previous Cisco DNA Center versions. The recommended versions are listed below on the Compatibility matrix.

Compatibility matrix

The following table shows the supported versions.

If your Ansible collection is older please consider updating it first.

Notes:

1. The "Python 'dnacentersdk' version" column has the minimum recommended version used when testing the Ansible collection. This means you could use later versions of the Python "dnacentersdk" than those listed.
2. The "Cisco DNA Center version" column has the value of the dnac_version you should use for the Ansible collection.

Installing according to Compatibility Matrix

For example, for Cisco DNA Center 2.2.2.3, it is recommended to use Ansible "cisco.dnac" v3.3.1 and Python "dnacentersdk" v2.3.3.

To get the Python DNA Center SDK v2.3.3 in a fresh development environment:

sudo pip install dnacentersdk==2.3.3

To get the Ansible collection v3.3.1 in a fresh development environment:

ansible-galaxy collection install cisco.dnac:3.3.1

Requirements

• Ansible >= 2.15
• Python DNA Center SDK v2.7.0 or newer
• Python >= 3.9, as the DNA Center SDK doesn't support Python version 2.x

Install

Ansible must be installed (Install guide)

sudo pip install ansible

Python DNA Center SDK must be installed

sudo pip install dnacentersdk

Install the collection (Galaxy link)

ansible-galaxy collection install cisco.dnac

Using this collection

There are three ways to use it:

• Using environment variables
• Using vars_files

Using environment variables

First, export the environment variables where you specify your DNA Center credentials as ansible variables:

export DNAC_HOST=<A.B.C.D>
export DNAC_PORT=443 # optional, defaults to 443
export DNAC_USERNAME=<username>
export DNAC_PASSWORD=<password>
export DNAC_VERSION=2.3.7.6 # optional, defaults to 2.3.7.6. See the Compatibility matrix
export DNAC_VERIFY=False # optional, defaults to True
export DNAC_DEBUG=False # optional, defaults to False

Create a hosts (example) file that uses [dnac_servers] with your Cisco DNA Center Settings:

[dnac_servers]
dnac_server

Then, create a playbook myplaybook.yml (example) referencing the variables in your credentials.yml file and specifying the full namespace path to the module, plugin and/or role:

- hosts: dnac_servers
  gather_facts: false
  tasks:
  - name: Create tag with name "MyNewTag"
    cisco.dnac.tag:
      state: present
      description: My Tag
      name: MyNewTag
    register: result

Execute the playbook:

ansible-playbook -i hosts myplaybook.yml

Using vars_files

First, define a credentials.yml (example) file where you specify your DNA Center credentials as Ansible variables:

---
dnac_host: <A.B.C.D>
dnac_port: 443  # optional, defaults to 443
dnac_username: <username>
dnac_password: <password>
dnac_version: 2.3.7.6  # optional, defaults to 2.3.7.6. See the Compatibility matrix
dnac_verify: False  # optional, defaults to True
dnac_debug: False  # optional, defaults to False

Create a hosts (example) file that uses [dnac_servers] with your Cisco DNA Center Settings:

[dnac_servers]
dnac_server

Then, create a playbook myplaybook.yml (example) referencing the variables in your credentials.yml file and specifying the full namespace path to the module, plugin and/or role:

- hosts: dnac_servers
  vars_files:
    - credentials.yml
  gather_facts: false
  tasks:
  - name: Create tag with name "MyNewTag"
    cisco.dnac.tag:
      dnac_host: "{{dnac_host}}"
      dnac_username: "{{dnac_username}}"
      dnac_password: "{{dnac_password}}"
      dnac_verify: "{{dnac_verify}}"
      state: present
      description: My Tag
      name: MyNewTag
    register: result

Execute the playbook:

ansible-playbook -i hosts myplaybook.yml

In the playbooks directory you can find more examples and use cases.

Attention macOS users

If you're using macOS you may receive this error when running your playbook:

objc[34120]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called.
objc[34120]: +[__NSCFConstantString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.
ERROR! A worker was found in a dead state

If that's the case try setting this environment variable:

export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES
