Yum module in Ansible | Normally to install ,upgrade or remove a
package we use yum command in linux
operating system .Similarly when we are going to install a package using

How to update all packages in ansible
To update all packages at a time we use ‘*’ symbol in the name parameter in Ansible and you must mention the state to latest to update all packages.
- hosts: node1
tasks:
- name: Upgrade all yum packages
yum:
name: "*"
state: latest
tasks:
- name: Upgrade all yum packages
yum:
name: "*"
state: latest
If you want to update all packages except some package you must specify ‘exclude’ parameter which contains which packages you don’t want to update.
In the below example we want to update all packages except php package.
- hosts: node1
tasks:
- name: Exclude some packages for upgrade
yum:
name: "*"
state: latest
exclude: php*

- name: Exclude some packages for upgrade
yum:
