Ansible with Ubuntu

1. setup ansible playbook from ppa for latest available update
2. create sample local playbook <E.g. whoami>
3. execute playbook to remote server

---

The first task - setup ansible package from ppa

just a simple command

sudo apt-get install software-properties-common
sudo apt-add-repository ppa:ansible/ansible
sudo apt-get update
sudo apt-get install -y ansible

at least, the current stable version is 1.9.x to check the latest version from github repository, and check ansible is ready from command

ansible-playbook --version

---

The second task - hello world

we have to create a simple playbook

echo '
---
- hosts: all
  tasks:
    - name: Hello
      shell: echo "Hello world"
' > /tmp/playbook.yml

and execute the playbook with command

ansible-playbook -i "localhost," -c local /tmp/playbook.yml -v

so the output you could see like this

PLAY [all] ********************************************************************

GATHERING FACTS ***************************************************************
ok: [localhost]

TASK: [Hello] *****************************************************************
changed: [localhost] => {"changed": true, "cmd": "echo \"Hello world\"", "delta": "0:00:00.001152", "end": "2015-10-26 18:14:33.107658", "rc": 0, "start": "2015-10-26 18:14:33.106506", "stderr": "", "stdout": "Hello world", "warnings": []}

PLAY RECAP ********************************************************************
localhost                  : ok=2    changed=1    unreachable=0    failed=0

---

The third task - remote server

we can use these command to execute playbook on remote server

ansible-playbook -k -u srandev -i "192.168.1.150," -c ssh ./playbook.yml -v

and the output

SSH password:

PLAY [all] ********************************************************************

GATHERING FACTS ***************************************************************
ok: [192.168.1.150]

TASK: [Hello] *****************************************************************
changed: [192.168.1.150] => {"changed": true, "cmd": "echo \"Hello world\"", "delta": "0:00:00.005768", "end": "2015-10-26 18:28:03.531380", "rc": 0, "start": "2015-10-26 18:28:03.525612", "stderr": "", "stdout": "Hello world", "warnings": []}

PLAY RECAP ********************************************************************
192.168.1.150              : ok=2    changed=1    unreachable=0    failed=0

options

• the option -k we use for asking ssh password
• the option -u for the remote ssh user, E.g. srandev
