- name: learning loops
become: no

file:
path: "{{ item }}"
state: touch
loop:
- /tmp/1.txt
- /tmp/2.txt
- /tmp/3.txt
- lists from variables
- name: learning loops
become: no
hosts: all
vars:
files:
- /tmp/4.txt
- /tmp/5.txt
- /tmp/6.txt
tasks:
- name: create files

- name: learning loops
become: no

- name: using debug module
ansible.builtin.debug:

Ansible lookups
- Ansible lookups will pull the data based on the lookup plugin we use
- Refer Here for the index of all lookup plugins
- File glob lookup can lookup for files in a directory with some pattern
- from the below example, let us fileglob pattern to find all the .sh files.

- name: learning lookups
become: no
hosts: all
tasks:
- name: print all shell files
debug:
msg: "{{ item }}"
with_fileglob:
- /tmp/test/*.sh
* Lets give execute permissions to all shell files

- name: learning lookups
become: no
hosts: all
tasks:
- name: print all shell files
file:
path: "{{ item }}"
mode: "+x"
with_fileglob:

Scenario: Installing tomcat9 on ubuntu 20.04 (contd..)
-
Refer Here for the changes done
- to add execute permissions to shell files in bin directory of tomcat
- create a service unit file and enable, start the service
- Try to write an ansible playbook to automate the above steps for centos7
