Use ansible to deploy iperf3

Step 1: Install Ansible (if not already installed):

On Linux (Ubuntu/Debian):

bash

sudo apt update 

sudo apt install ansible

Step 2: Set Up Your Inventory File

Create an Ansible inventory file to specify the target VMs. An example inventory file, inventory.ini, could look like this:

ini

[servers] server1 ansible_host=192.168.1.10 
server2 ansible_host=192.168.1.11 

[all:vars] ansible_user=your_user 
ansible_ssh_private_key_file=/path/to/your/private_key

Step 3: Install iperf3 on the Target VMs Using Ansible

To install iperf3 on your VMs, create an Ansible playbook (install_iperf3.yml) with the following content:

yaml

---
- name: Install iperf3 on target VMs
  hosts: servers
  become: yes
  tasks:
    - name: Install iperf3
      apt:
        name: iperf3
        state: present
      when: ansible_os_family == "Ubuntu"

Run this command to install iperf3 on all VMs

ansible-playbook -i inventory.ini install_iperf3.yml

Step 4: Configure and Run the iperf3 Test

Now, create a playbook (run_iperf3.yml) to configure and run the iperf3 network speed test between your VMs.

yaml

---
- name: Run iperf3 network speed test
  hosts: server1
  become: yes
  tasks:
    - name: Start iperf3 server
      command: iperf3 -s
      async: 3600
      poll: 0
      register: iperf3_server

    - name: Wait for server to start
      wait_for:
        host: "{{ ansible_host }}"
        port: 5201
        state: started
        delay: 5
        timeout: 30

    - name: Run iperf3 client test on server2
      delegate_to: server2
      command: iperf3 -c {{ hostvars['server1'].ansible_host }} -t 30
      register: iperf3_result

    - name: Store results in result.txt
      copy:
        content: "{{ iperf3_result.stdout }}"
        dest: "/tmp/result.txt"

Use this command to run the playbook above which runs iperf3 on vms

ansible-playbook -i inventory.ini run_iperf3.yml

You can view the results of the file with

This downloads the file from server 2

scp your_user@192.168.1.11:/tmp/result.txt ./result.txt
