Format Output in Ansible

 

 Ansible

To properly format the ouput of the ansible playbook output

Create a ansible.cfg as follows and add the following content

/etc/ansible/ansible.cfg

[defaults]
# Use the YMAL callback plugin
stdout_callback = yaml
# Use the stdout_callback when running ad-hoc commands
bin_ansible_callbacks = True
interpreter_python = auto_silent

Execute the playbook and you will see the formatted output as follows

ansible@ansible-VirtualBox:~/Desktop$ ansible-playbook shell.yml -v

    Hello from Docker!
    This message shows that your installation appears to be working correctly.
 
    To generate this message, Docker took the following steps:
     1. The Docker client contacted the Docker daemon.
     2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
        (amd64)
     3. The Docker daemon created a new container from that image which runs the
        executable that produces the output you are currently reading.
     4. The Docker daemon streamed that output to the Docker client, which sent it
        to your terminal.
 
    To try something more ambitious, you can run an Ubuntu container with:
     $ docker run -it ubuntu bash
 
    Share images, automate workflows, and more with a free Docker ID:
     https://hub.docker.com/
 
    For more examples and ideas, visit:
     https://docs.docker.com/get-started/

Install Apache using Ansible

  

Ansible 

Create a yaml file as follows

cat apache.yml
---
 - hosts: localhost
   become: yes
   become_method: sudo
   become_flags: -s
   become_user: root
   tasks:
   - name: Install Apache
     apt:
       name: apache2
       state: present
       update_cache: true 

or

Syntax 2:

cat apache_1.yml
---
 - hosts: localhost
   become: yes
   become_method: sudo
   become_flags: -s
   become_user: root
   tasks:
   - name: Install Apache
     apt: name=apache2 state=present update_cache=yes
 

and run the apache.yml playbook

ansible@ansible-VirtualBox:~/Desktop$ ansible-playbook -v apache.yml

Check the host on which Apache is running by using hostname - I command and then launch a browser and connect to the IP addresses mentioned

ansible@ansible-VirtualBox:~/Desktop$ hostname -I
10.0.2.15 172.17.0.1 

Launched the first IP and have set the following page in the index.html

you can check the status of apache service

ansible@ansible-VirtualBox:~/Desktop$ ps -ef|grep apache
root         639       1  0 10:52 ?        00:00:00 /usr/sbin/apache2 -k start

ansible     4361    1754  0 11:33 pts/0    00:00:00 grep --color=auto apache

You can configure your own page by following the below link

https://ubuntu.com/tutorials/install-and-configure-apache#1-overview

For now I'll set the apache index.html back 

Go to /var/www/html and rename the current index.html and move the original one back into the place

ansible@ansible-VirtualBox:/var/www/html$ ls
index.html  index.html_bak_24Apr21
ansible@ansible-VirtualBox:/var/www/html$ sudo mv index.html index.html_25Apr21
ansible@ansible-VirtualBox:/var/www/html$ sudo mv index.html_bak_24Apr21 index.html

Restart the services:

ansible@ansible-VirtualBox:/var/www/html$ systemctl reload apache2

Relaunch the IPs in the browser and you will see the original apache page

For port configuration, refer to: https://www.scaleway.com/en/docs/how-to-install-apache-on-ansible/
