Lab

This lab is designed to have the engineer verify and execute their automation tools in a controlled environment.

Bash Execution

Execute some simple commands within your bash shell.

1. Verify your location and version of bash

   which bash
   /usr/bin/bash --version
   

2. Verify your shell PID

   echo $$
   

3. Verify your shell variable

   echo $SHELL
   

4. Loop over your target servers (use your target servers).
   

   for server in target1-1 target1-2; do timeout 10 ssh svc_ansible@$server 'uptime'; done
   

   Enter your password for the svc_ansible user from the lab guide.
   • If doing the lab on Killercoda, your target servers are controlplane and node01.
   • If in the ProLUG lab environment, check the lab guide for your target servers.

Python Execution

Test and execute Python.

1. Verify your version of Python

   python3 --version
   

2. Test that you can import modules

   python3      # Will drop you into interactive shell
   import os    # Should work with no output
   import numpy # Should not work as you don’t have numpy on the system
   exit()       # Will exit the interactive python3 environment.
   

Ansible Execution

Test and execute Ansible.

1. Verify your version of Ansible

   ansible –version
   

2. Check other ansible tools

   ansible- <tab><tab>
   

   The Tab+Tab will trigger autocompletion, showing what commands are available that start with ansible-.

3. Check modules

   ansible-doc -l
   ansible-doc -l | wc -l
   ansible-doc -l | grep -i copy
