NetScaler ADC Collection

Description

The collection provides Ansible modules to configure and manage NetScaler ADC appliances. The modules are written using the NITRO API. The modules are idempotent and can be used to configure the NetScaler ADC appliances in a declarative manner.

Requirements

Ansible version compatibility

Tested with Ansible Core >=2.15 versions.

Python version compatibility

Tested with Python >=3.11

Installation

via Ansible-galaxy

The netscaler.adc collection can be installed with the Ansible Galaxy command-line tool:

ansible-galaxy collection install netscaler.adc

via Github (to have the latest updated which are yet to be released in ansible-galaxy)

ansible-galaxy collection install "git+https://github.com/netscaler/ansible-collection-netscaleradc.git" [--force]

--force option is required if you have already installed the collection via ansible-galaxy. This will overwrite the existing collection with the latest collection from github.

To verify the installation, run the following command:

ansible-galaxy collection list netscaler.adc

The above command should display the below output:

# /Users/netscaleruser/.ansible/collections/ansible_collections
Collection    Version
------------- -------
netscaler.adc 2.8.x

Usecases

The modules can be called by their Fully Qualified Collection Name (FQCN) such as netscaler.adc.lbvserver, or by their short name netscaler.adc if the collection is listed under the playbook's collections attribute:

Usecase by FQCN

---
- name: Sample lbvserver playbook
  hosts: demo_netscalers
  gather_facts: false
  tasks:
    - name: Configure lbvserver
      delegate_to: localhost
      netscaler.adc.lbvserver:
        nsip: "{{ nsip }}"
        nitro_user: "{{ nitro_user }}"
        nitro_pass: "{{ nitro_pass }}"
        nitro_protocol: "{{ nitro_protocol }}"
        validate_certs: false
        save_config: false
        state: present
        name: lb_dns_01
        servicetype: HTTP

Usecase by declaring collection

---
- name: Sample lbvserver playbook
  hosts: demo_netscalers
  gather_facts: false
  collections:
      - netscaler.adc
  tasks:
    - name: Configure lbvserver
      delegate_to: localhost
      lbvserver:
        nsip: "{{ nsip }}"
        nitro_user: "{{ nitro_user }}"
        nitro_pass: "{{ nitro_pass }}"
        nitro_protocol: "{{ nitro_protocol }}"
        validate_certs: false
        save_config: false
        name: lb_dns_01
        servicetype: HTTP

Usecase by netscaler.adc.module_default group

---
- name: Sample Playbook to use module_defaults to specify common arguments
  hosts: localhost
  gather_facts: false
  module_defaults:
    group/netscaler.adc.default_args:
      nsip: 10.10.10.10
      nitro_user: nsroot
      nitro_pass: verysecretpassword
      nitro_protocol: http
      validate_certs: false
      save_config: false
  tasks:
    - name: Sample Task | ipset
      delegate_to: localhost
      netscaler.adc.lbvserver:
        name: lb_dns_01
        servicetype: HTTP

NetScaler Console (ADM) as a Proxy Server

The collection supports configuring NetScaler Console as a proxy server. This is useful when you have multiple NetScaler ADC appliances and you want to manage them using a single NetScaler Console.

An example can be found in examples/netscaler_console_as_proxy_server.yaml.

Refer to the NetScaler ADM as an API proxy server for more details.

Examples and playbook anatomy

Refer to the sample_playboook and playbook_anatomy.md.

SSH_connections

Refer to SSH_connections examples to know how ansible.builtins. plugins can be used to configure the NetScaler ADC.

Authentication

Authenticate to NetScaler via username and password

Every module in the collection requires the user to authenticate to the NetScaler ADC appliance. To authenticate, provide the nsip, nitro_user and nitro_pass parameters directly or set them using environment variables NETSCALER_NSIP, NETSCALER_NITRO_USER and NETSCALER_NITRO_PASS.

Refer to the playbook_anatomy.md and sessionid_based_authentication_via_login_logout.yaml example playbook.

login module requires username and password parameters to be passed. If you do not wish to pass the username and password, refer below.

You can use the below curl command to generate the token. The token can be passed to other modules using the nitro_auth_token parameter. The nitro_auth_token parameter can also be passed as environment variable NETSCALER_NITRO_AUTH_TOKEN. The token is valid for 60 minutes.

The below command also uses jq to parse the JSON output and store the sessionid in the NETSCALER_NITRO_AUTH_TOKEN environment variable, so that it can be used by other modules.

Note: Change the NETSCALER_NSIP, NETSCALER_NITRO_USER and NETSCALER_NITRO_PASS. Install jq util if not already installed.

export NETSCALER_NITRO_AUTH_TOKEN=$(curl -X POST -H "Content-Type:application/json" --insecure --silent https://NETSCALER_NSIP/nitro/v1/config/login -d '{"login":{"username":"NETSCALER_NITRO_USER", "password":"NETSCALER_NITRO_PASS"}}' | jq .sessionid)
echo $echo $NETSCALER_NITRO_AUTH_TOKEN

Invocation

The credentials of the netscaler can be provided either in the playbook by hardcoding or defining in a inventory.ini file.

Execution command when hosts are declared in playbook:

ansible-playbook playbook.yaml [--verbose]

Execution command hosts are declared in an inventory file:

ansible-playbook playbook.yaml -i inventory.ini [--verbose]
