Ansible contd

Installing spc on redhat 9

• Manual steps

sudo dnf install java-17-openjdk -y

# for rest of steps refer previous classroom notes

• Refer Here for the changes done to accomodate the redhat support

Accomodating changes in values

• For instance, few months down the line i might need to install java 21 or the username should be something else or url etc
• In ansible we can create variables.
• Variables can be passed at runtime and also can have default values if not passed
• Ansible allows to create variables at multiple locations (TBD)
• Refer Here for offical docs
• debug module Refer Here

Variables in inventory

• Generally when we define variables at inventory we have two types of variables
  • host variables:
  • group variables:
• Refer Here for a host level varaible defined in inventory
• Updated the playbook to use generic package manager Refer Here
• Refer Here for the changes to use group variables
• Ansible provides a better way for creating host and group variables by using host_vars directory and group_vars directory,
• Refer Here for the changes

Good Practice

• Ensure you add necessary debug statements to inform users about activities

Templating

• Ansible uses jinja templates to handle dynamic content in files Refer Here
