I’ve written about NTC-Ansible a couple of times already and thought now would be a good time to run you through the installation process. The github page provides some great information on the process, but I’d like to add a few extra details in this post.
Note that there are two ways in which you can install custom modules. They work as well as one another so it’s up to you which you choose.
Both methods require the following tasks be completed:
- Clone the ntc-ansible repository:
git clone https://github.com/networktocode/ntc-ansible --recursive
- Install pip if it hasn’t already been installed:
sudo apt install python-pip
- Install the ntc-ansible dependencies:
pip install ntc-ansible
Method #1 – Configuration directory
Move the filter_plugins , library and ntc-templates directories so that they’re in the same location as your Playbooks. For example, if your directory structure currently looks like this:
├── site.yml ├── group_vars │ ├── all.yml ├── hosts.ini ├── roles ├── common └── gns3 ├── tasks ├── main.yml
It should look like this after the directory moves:
├── filter_plugins │ ├── <files> ├── library │ ├── <files> ├── ntc-templates │ ├── <files> ├── site.yml ├── group_vars │ ├── all.yml ├── hosts.ini ├── roles ├── common └── gns3 ├── tasks ├── main.yml
Note: See my “Anatomy of an Ansible Playbook” post for more information on Ansible directory structures.
Once you’ve moved the directories across, you’re ready to start using the NTC Ansible modules.
Method #2 – Modules directory
- Move the filter_plugins and ntc-templates so that they’re in the same location as your Playbooks (see Method #1 for more information). Do not move the library directory to this location.
- By default, Ansible’s module search path is /usr/share/my_modules/ . You can check if this has been overridden by using the following command:
will@ubuntu:/tmp$ ansible --version ansible 126.96.36.199 config file = /etc/ansible/ansible.cfg configured module search path = Default w/o overrides
- Create an ntc-ansible directory in the module search path directory.
- Move the NTC Ansible library directory into the ntc-ansible directory you’ve just created.
Your directory structure should now look like this:
will@ubuntu:/usr/share/my_modules/ntc-ansible$ ls library
You’re ready to start using the NTC Ansible modules.
Note: If this process does not work and you’ve got the configured module search path set to default, edit its library path in /etc/ansible/ansible.cfg and point it to the directory parent directory of ntc-ansible . For example:
will@ubuntu:/tmp$ ansible --version ansible 188.8.131.52 config file = /etc/ansible/ansible.cfg configured module search path = ['/usr/share/my_modules/']
