My first Playbooks

 in the next blog we will start to create some simple playbooks to do the following:

1. transfer a new hosts file to the clients 

2. install some packages on the clients

Transfer a new hosts file to the clients:

1. I created the hosts file that I will transfer to to the clients.

root@dcex1510ctrl001:~# cat /root/files/hosts
127.0.0.1 localhost
10.11.25.66 dcex1510ctrl001
10.11.25.67 dcex1510clnt001
10.11.25.68 dcex1510clnt002

2. I created the playbook itself

root@dcex1510ctrl001:~# cat ansible/playbooks/hostsfile.yaml

- name: Ansible copy a file from the master node to the clients

  hosts: client01

  tasks:

    - name: Copying hosts file to another server

      become: true

      copy:

        src: /root/files/hosts

        dest: /etc/hosts

        owner: root

        group: root

        mode: 0644

3. I executed the playbook

ansible-playbook -i ansible/hosts/hosts.ini ansible/playbooks/hostsfile.yaml

Just a reminder for my hosts file 

root@dcex1510ctrl001:~# cat ansible/hosts/hosts.ini
[client01]
10.11.25.67 ansible_user=root ansible_password=ABCD1234;

[client02]
10.11.25.68 ansible_user=root ansible_password=ABCD1234;

[all:children]
client01
client02

4. As we need to make the same hosts file in the 2 clients, I will change the hosts in the above playbook

root@dcex1510ctrl001:~# cat ansible/playbooks/hostsfile.yaml

- name: Ansible copy a file from the master node to the clients

  hosts: all

  tasks:

    - name: Copying hosts file to another server

      become: true

      copy:

        src: /root/files/hosts

        dest: /etc/hosts

        owner: root

        group: root

        mode: 0644

Install and remove a package on the clients:

root@dcex1510ctrl001:/# cat /root/ansible/playbooks/apacheInstall.yaml

- name: Ansible playbook to install and remove apache package, it is used just for testing a simple playbook

  hosts: all

  tasks:

  - name: Install Apache

    apt:

      name: apache2

      state: present

  - name: Remove Apache

    apt:

     name: apache2

     state: absent

root@dcex1510ctrl001:/# ansible-playbook -i /root/ansible/hosts/hosts.ini /root/ansible/playbooks/apacheInstall.yaml
