Dear Readers,
In this article,we will see Push Code From Ansible Server to Hosts by using Single Module.
Modules
- Ansible modules are discrete units of code which can be used from the command line or in a playbook task.
- The modules also referred to as task plugins or library plugins in the Ansible.
- Ansible ships with several modules that are called module library, which can be executed directly or remote hosts through the playbook.
- We can execute the modules from the command line.
- Ansible executes each module, usually on the remote target node, and collects return values.
Steps to Follow
- Connect to Ansible Linux EC2 Terminal through Putty.
- See the full information of 2 hosts (Gathering facts).
- See the hostname of 2 hosts.
- Install package “httpd” inside 2 nodes inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Upgrade package “httpd” inside 2 nodes inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Remove package “httpd” inside 2 nodes inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Create a file “ktexperts” inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Remove a file “ktexperts” inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Create a directory “ktexperts-dir” inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Remove a directory “ktexperts-dir” inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”
- Create a user “rammy” inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Create a group “Ktexperts-DevOps” inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Add user “rammy” to group “Ktexperts-DevOps”.
- Remove user “rammy” inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Remove group “Ktexperts-DevOps” inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”.
- Download the package from the internet to 2 hosts.
- Copy file “ktexperts” from ansible server to 2 hosts.
- Start the service “httpd” in 2 hosts.

Setup Module
To gets information about the network or hardware or OS version or memory-related information the setup module will help to gather the same about the target machines.

4. Install package “httpd” inside 2 nodes inside the 2 hosts “Ansible-Node-1” and “Ansible-Node-2”
We can push code from Ansible Server to hosts by using a single module.
