Ansible role: Weave Net

This role is child role of net_addon and used to install and configure weave-net.

For now, it does the following:

• open ports
• create project working directory for role on localhost
• create secret if needed and install weave-net

Requirements

This is not strict requirements and it may not work with other versions than tested ones. Anyway. feel free to test by yourself, suggest addition of new functionality and contribute.

Role is tested with:

• Ansible version >= 2.8.6
• CentOS version >= 7.6 (1803)

Currently supports only 'with_k8s' deployment type, it means that weave-net will be installed into kubernetes cluster, which must be present as well as credentials to it.

Example Playbook

---
- hosts: localhost
  gather_facts: false
  become: no
  tasks:
  - name: Check ansible version >=2.8.6
    assert:
      msg: Ansible must be v2.8.6 or higher
      that:
      - ansible_version.string is version("2.8.6", ">=")
    tags:
    - check
  vars:
    ansible_connection: local

- hosts: all
  become: yes
  tasks:
  # From parent role when "net_addon_name: weave_net" is set inside your variables:
  - import_role:
      name: caermeglaeddyv.ansible_role_net_addon
  # Or directly:
  - import_role:
      name: caermeglaeddyv.ansible_role_weave_net

More detailed examples ( inventories, playbooks etc. ) of this and other roles can be found here.

It's highly recommended to start you test deploys from there, especially if you use Google Cloud Platform or VMware vCenter as your infrastructure, for now that repository contains Packer and Terraform examples to build templates and deploy machines on this platforms.
