Ansible playbook for installation on Ubuntu

[Kircheneer]

I've built a little Ansible playbook (nothing fancy really) to install this tool on a Ubuntu 20.04 machine because I didn't feel like going through the steps each time I rebuilt my lab VM. Playbook below. If this is something the project would be interested in I could clean it up a little and submit a PR.

- name: Install netsim-tools and dependencies for libvirt provider
  hosts: localhost
  connection: local
  vars:
    plugin_file: "{{ lookup('file','~/.vagrant.d/plugins.json') | from_json }}"
    clone_to: /opt/netsim-tools
    vagrant_libvirt_version: 0.4.1
    netsim_tools_version: release_0.6.1
    vagrant_libvirt_installed: "{{ plugin_file.installed.vagrant_libvirt is not defined or plugin_file.installed.vagrant_libvirt.gem_version != vagrant_libvirt_version }}"
  tasks:
  - name: Install apt dependencies
    apt:
      pkg:
        - libvirt-dev
        - qemu-kvm
        - vagrant
        - virtinst

        - libxml2-dev

        - ruby-dev
        - python3-venv
    become: yes
  - name: Install vagrant-libvirt Vagrant plugin
    shell: "vagrant plugin install vagrant-libvirt --plugin-version={{ vagrant_libvirt_version }}"
    when: not vagrant_libvirt_installed
  - name: Clone netsim-tools
    git:
      repo: https://github.com/ipspace/netsim-tools.git
      version: "{{ netsim_tools_version }}"
      dest: "{{ clone_to }}"
    become: yes
  - name: Change owner of netsim-tools folder to current user
    file:
      path: "{{ clone_to }}"
      owner: "{{ ansible_effective_user_id }}"
      group: "{{ ansible_effective_group_id }}"
    become: yes
  - name: Create a python virtual environment and install requirements
    shell:
      cmd: python3 -m venv venv
      chdir: "{{ clone_to }}"
      creates: "{{ clone_to }}/venv"
  - name: Install requirements.txt
    shell:
      cmd: "{{ clone_to }}/venv/bin/pip install -r requirements.txt"
      chdir: "{{ clone_to }}"
  - name: Delete existing vagrant-libvirt network
    shell: virsh net-undefine vagrant-libvirt && virsh net-destroy vagrant-libvirt
    failed_when: False
  - name: Add vagrant-libvirt virtual network from netsim-tools template
    shell: "virsh net-define {{ clone_to + '/netsim/templates/provider/libvirt/vagrant-libvirt.xml' }}"

This is great. Please put it the home directory (maybe rename to install.libvirt?) and submit a PR. A trick I find useful is to make an Ansible playbook executable and use shebang to point to Ansible.

The one thing I'm worried about is what happens when there's no Vagrant plugin file to start with. Maybe you should add errors="ignore" to the lookup?

[Kircheneer]

Will do. One thought I wanted to discuss before that: This playbook clones the netsim-tools repository - isn't that a bit redundant when you have to get the repository to use the playbook? Or would the workflow be copy-pasting the playbook from the GitHub website?

#8 created for this.

This functionality has been superseded by the netlab install command.
