# Learn by doing. NoM Ansible Training #1

## 1. Install Ansible

On Ubuntu:

```auto
sudo apt update
sudo apt install software-properties-common
sudo add-apt-repository --yes --update ppa:ansible/ansible
sudo apt install ansible

```

## 2. What is Idempotence?

```auto
# Try the following commands
mkdir testdirectory1
mkdir testdirectory1
# What happens?

# Clean Up
rm -r testdirectory1

# Try a slightly different command
mkdir -p testdirectory1
mkdir -p testdirectory1
# What happens?

```

## 3. Do it via Ansible

Create a file called `playbook.yaml` with the following contents.  
Note that we are creating two different directories.

```auto
- name: test-playbook
  hosts: localhost
  tasks:
  - name: Creates directory 1
    ansible.builtin.file:
      path: testdirectory1
      state: directory
  - name: Creates directory 2
    ansible.builtin.file:
      path: testdirectory2
      state: directory

```

Then run the following command twice.

```auto
ansible-playbook playbook.yaml
ansible-playbook playbook.yaml
# What happens?

# Delete only one
rm -r testdirectory1

# Again
ansible-playbook playbook.yaml

```
