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.
The following table shows the supported versions.
| Cisco DNA Center version | Ansible "cisco.dnac" version | Python "dnacentersdk" version |
|---|---|---|
| 2.2.2.3 | 3.3.1 | 2.3.3 |
| 2.2.3.3 | 6.4.0 | 2.4.11 |
| 2.3.3.0 | 6.6.4 | 2.5.5 |
| 2.3.5.3 | 6.13.3 | 2.6.11 |
| 2.3.7.6 | 6.24.0 | 2.7.4 |
| 2.3.7.6 | ^6.25.0 | ^2.7.5 |
If your Ansible collection is older please consider updating it first.
Notes:
- 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.
- The "Cisco DNA Center version" column has the value of the
dnac_versionyou should use for the Ansible collection.
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
- 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
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
There are three ways to use it:
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
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.
Getting the latest/nightly collection build
Clone the dnacenter-ansible repository.
git clone https://github.com/cisco-en-programmability/dnacenter-ansible.git
Go to the dnacenter-ansible directory
cd dnacenter-ansible
Pull the latest master from the repo
git pull origin master
Build and install a collection from source
ansible-galaxy collection build --force
ansible-galaxy collection install cisco-dnac-* --force

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
