Ansible. Need I say more? Well, maybe, if you’ve never heard of it. Ansible is a simple IT / DevOps automation that anyone can use. You can Automate anything with an SSH connection and WITHOUT installing any agents or clients. Join me as we set up, configure and start automating with Ansible!

Installing the latest version of Ansible
Most distributions have an older version of Ansible installed. This is usually fine except sometimes you may need to use features from the latest Ansible. Use the following commands to update Ansible to the latest version.
Check version
1
ansible --version
If it’s not the version you are looking for, check to see where it is installed
1
which ansible
If it lives somewhere like
1
/usr/bin/ansible
this is most likely due to your distribution installing it there.
Remove previous version
1
sudo apt remove ansible
Check to be sure it is removed
1
which ansible
You should see
1
ansible not found
check to see that you have python3 and pip
1
python3 -m pip -V
You should see something like
1
pip 22.3.1 from /home/user/.local/lib/python3.8/site-packages/pip (python 3.8)
Install pip if the previous couldn’t find the pip module
1
curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py
Install ansible
1
python3 -m pip install --user ansible
Confirm your version with
1
ansible --version
