NSO Ansible MOPs

Ansible playbook to automate MOPs for network device upgrades.

Requirements

• Ansible 2.6 or later

  • This playbook relies on Ansible modules for NSO available since Ansible 2.5 (nso_action and nso_config). However, there are important fixes to those modules which are only available in Ansible 2.6.
  • Before Ansible 2.6 is released, please use the dev branch (https://github.com/ansible/ansible)

• NSO health-snapshots package

  • The health-snapshots package is used for pre-post checks as well as verifying that the device is functional after a reload.
  • This package is available here: https://github.com/reismarcelo/device-health-snapshots

• Device to be upgraded

  • This playbook currently only supports XR devices.
  • The XR image tar file needs to be in the location specified by 'xr_package' variable.

Configuration

Commonly used configuration parameters for the playbook are available in the group_vars/all.yml file.

Running the playbook

# ansible-playbook asr9k_upgrade.yaml

Service affecting tasks are tagged with 'service_impact'. The '--skip-tags' option can be used if one needs to run the playbook without going through service affecting tasks:

# ansible-playbook asr9k_upgrade.yaml --skip-tags=service_impact
