Introduction

Ansible is open-source server management and automation software that enables Infrastructure as Code (IaC). This tool allows application deployment, provisioning, and configuration management simply and effectively.

Ansible Automation Hub gathers modules from Red Hat and certified partners. phoenixNAP is proud to be a part of the Ansible trusted content collection with the Bare Metal Cloud plugin. This concept that Ansible introduced makes it possible to install cloud providers as additional libraries.

Follow the steps in this guide to install the phoenixNAP BMC Ansible module and learn how to use relevant playbooks.

Prerequisites

• Ansible installed on the control machine
• Python installed on the control machine (available by default)

Benefits of Using PNAP BMC Ansible Module

This IaC tool was designed to allow customers to provision Bare Metal Cloud servers and perform other tasks using simple YAML scripts called playbooks. You can now efficiently automate server creation with immutable provisioning. Besides the benefit of automating IT processes, another bonus is the ability to rerun the same code to revert a server to the original state in case of unwanted modifications.

This model does not have master and slave machines. You use one machine to push the files, i.e., run a script on one or multiple remote hosts. There are no agents on individual nodes that pull information from the main server. Bare Metal Cloud module does not require SSH to run playbooks.

By becoming a certified plugin on Red Hat Ansible Automation Hub, the BMC module installation process is quick and completed using a single Ansible command. Then, you can instruct Ansible to run a script that contains the YAML code with the description of the automation job you want to perform. The module ensures to achieve the end result you specified, and in the correct sequence.

The content in the Ansible Automation Hub is supported by Red Hat and its partners. This way, even the most demanding environments can rest assured that the modules will live up to the expectations.

Install BMC Ansible Module

Before installing the BMC Ansible plugin, you need the Python requests package on your machine. It allows sending different types of HTTP requests.

To install requests, enter:

pip install requests

Then, run the Ansible command to install the phoenixNAP BMC module:

ansible-galaxy collection install phoenixnap.bmc

Once the installation completes, view the module documentation with this command:

ansible-doc phoenixnap.bmc.server

The Ansible BMC plugin depends on API requests. All BMC API requests are documented at the phoenixNAP Developers Portal.

Create Credential File for Authentication

To successfully authenticate with our authorization server, use the Client Credentials grant type.

In your home directory, create a directory .pnap and a config.yaml file inside it.

The file needs to contain the following information:

clientId: myClientId

clientSecret: myClientSecret

Replace myClientId and myClientSecret with your ID and secret.

Ansible phoenixNAP BMC Playbooks

Writing Ansible playbooks does not require special coding skills, and they cover all available BMC APIs. These scripts are written in YAML, a simple serialization language used when creating configuration files. Ansible works by checking the actual states of the servers and compares them with the set of instructions in the playbook.

When the state does not match the defined end result, the module ensures to follow the resource model from the script to reach the set goal.

If you run a playbook more than once, the module will not perform additional tasks. Once the actual state of a BMC server corresponds to the goal of the script, you can execute the script multiple times, and the module will not perform any task.

How to Run BMC Playbooks

The name of a playbook suggests what the script does. For example, playbook_power_off.yml turns off one or more servers.

To run a playbook, use this syntax:

ansible-playbook playbook_name.yml

Therefore, to reset a server, enter:

ansible-playbook playbook_reset.yml

BMC Playbook Examples

The YAML playbook examples we will provide below are similar to one another. The difference is the state of the server you want to achieve. The only file that is slightly more different than others is the script for creating a server.

Every playbook needs to contain one or more hostnames or server_ids, as well as the client_id and client_secret. The preferred method is to enter the values in the ~/.pnap/config.yaml file instead of in each playbook.

Create Server

The name of the playbook: playbook_create.yml

- name: Create new servers for account
  hosts: localhost
  gather_facts: false
  vars_files:
    - ~/.pnap/config.yaml
  collections:
    - phoenixnap.bmc
  tasks:
  - server:
      client_id: "{{clientId}}"
      client_secret: "{{clientSecret}}"
      hostnames: [my-server-red]
      location: PHX
      os: ubuntu/bionic
      type: s1.c1.medium
      state: present
      ssh_key: "{{ lookup('file', '~/.ssh/id_rsa.pub') }}"

Deprovision Server

The name of the playbook: playbook_deprovision.yml

- name: reset servers
  hosts: localhost
  gather_facts: false
  vars_files:
    - ~/.pnap/config.yaml
  collections:
    - phoenixnap.bmc
  tasks:
  - server:
      client_id: "{{clientId}}"
      client_secret: "{{clientSecret}}"
      hostnames: [my-server-red]
      state: absent

Power Off Server

The name of the playbook: playbook_power_off.yml

- name: power on servers
  hosts: localhost
  gather_facts: false
  vars_files:
    - ~/.pnap/config.yaml
  collections:
    - phoenixnap.bmc
  tasks:
  - server:
      client_id: "{{clientId}}"
      client_secret: "{{clientSecret}}"
      hostnames: [my-server-red]
      state: powered-off

Power On Server

The name of the playbook: playbook_power_on.yml

- name: power on servers
  hosts: localhost
  gather_facts: false
  vars_files:
    - ~/.pnap/config.yaml
  collections:
    - phoenixnap.bmc
  tasks:
  - server:
      client_id: "{{clientId}}"
      client_secret: "{{clientSecret}}"
      hostnames: [my-server-red]
      state: powered-on

Reboot Server

The name of the playbook: playbook_reboot.yml

- name: reset servers
  hosts: localhost
  gather_facts: false
  vars_files:
    - ~/.pnap/config.yaml
  collections:
    - phoenixnap.bmc
  tasks:
  - server:
      client_id: "{{clientId}}"
      client_secret: "{{clientSecret}}"
      hostnames: [my-server-red]
      state: rebooted

Reset Server

The name of the playbook: playbook_reset.yml

- name: reset servers
  hosts: localhost
  gather_facts: false
  vars_files:
    - ~/.pnap/config.yaml
  collections:
    - phoenixnap.bmc
  tasks:
  - server:
      client_id: "{{clientId}}"
      client_secret: "{{clientSecret}}"
      hostnames: [my-server-red]
      ssh_key: "{{ lookup('file', '~/.ssh/id_rsa.pub') }}"
      state: reset

Shutdown Server

The name of the playbook: playbook_shutdown.yml

In this example, we used server_ids instead of hostnames.

- name: shutdown servers
  hosts: localhost
  gather_facts: false
  vars_files:
    - ~/.pnap/config.yaml
  collections:
    - phoenixnap.bmc
  tasks:
  - server:
      client_id: "{{clientId}}"
      client_secret: "{{clientSecret}}"
      server_ids:
        - 5eda71ef674cf47bd2599cfa
      state: shutdown
