Nodegrid upgrade through Redhat server

Nodegrid upgrade through Redhat server

Ansible can be used to upgrade Nodegrid device to newer version from server ( Redhat in this case ).
Make sure ISO file has been copied to /etc/ansible/Firmware/ folder.

First, one needs to create template to be copied on remote Nodegrid device.
nodegrid_upgrade.j2

  2. software_upgrade
  3. set image_location=local_system
  4. set filename={{ ng_filename }}
  5. upgrade
Next, one needs to create playbook : nodegrid_upgrade.yml

  3.  - name: Upgrade the Nodegrid
  4.    hosts: "{{ ipaddress }}"
  5.    gather_facts: no
  6.    vars_prompt:
  7.       - name: ipaddress
  8.         prompt: Enter the ip address or group name
  9.         private: no
  10.    vars:
  11.     ng_filename: Nodegrid_Platform_v4.2.1_20200626.iso
  12.     ng_full: /etc/ansible/Firmware/{{ ng_filename }}
  13.     ng_dest: /var/sw/{{ ng_filename }}
  14.     file_name_upgrade: upgrade.cli
  15.     file_name_backup: backup.cli
  16.     become: true

  18.    tasks:
  19.    - name: Copy ISO to Nodegrid
  20.      copy:
  21.       src: "{{ ng_full }}"
  22.       dest: "{{ ng_dest }}"

  24.    - name: Copy firmware update script
  25.      template:
  26.       src: templates/nodegrid_upgrade.j2
  27.       dest: /tmp/{{ file_name_upgrade }}

  29.    - name: Run Firmware update
  30.      command : cli -f /tmp/{{ file_name_upgrade }}

  32.    - name: Wait 300 seconds for target connection to become reachable/usable
  33.      wait_for_connection:
  34.       delay: 60
  35.       timeout: 300

  37.    - name: Current Version
  38.      command : grep ^VERSION= /software
  39.      register: ng_version_after

  41.    - name: Upgrade Successful
  42.      debug:
  43.        msg: "Upgrade successful new version: {{ ng_version_after['stdout'] }}"

  45.    - name: Deleting Cache
  46.      wait_for_connection:
  47.        delay: 5
  48.        timeout: 10

  50.    - name: Find and Delete
  51.      shell: sudo rm -rf /var/sw/*

  53.    - name: ACK
  54.      debug:
  55.        msg: " Nodegrid is up and running "   
Now, run the playbook with the command: ansible-playbook nodegrid_upgrade.yml
