[All EX294 Questions]

Create a playbook called balance.yml as follows:

* The playbook contains a play that runs on hosts in balancers host group and uses

the balancer role.

--> This role configures a service to loadbalance webserver requests between hosts

in the webservers host group.curl

--> When implemented, browsing to hosts in the balancers host group (for example

http://node5.example.com) should produce the following output:

Welcome to node3.example.com on 192.168.10.z

--> Reloading the browser should return output from the alternate web server:

Welcome to node4.example.com on 192.168.10.a

* The playbook contains a play that runs on hosts in webservers host group and uses

the phphello role.

--> When implemented, browsing to hosts in the webservers host group with the URL /

hello.php should produce the following output:

Hello PHP World from FQDN

--> where FQDN is the fully qualified domain name of the host. For example,

browsing to http://node3.example.com/hello.php, should produce the following output:

Hello PHP World from node3.example.com

following output:

Hello PHP World from node4.example.com

AExplanation:
Solution as:
# pwd
/home/admin/ansible/
# vim balancer.yml
---
- name: Including phphello role
hosts: webservers
roles:
- ./roles/phphello
- name: Including balancer role
hosts: balancer
roles:
- ./roles/balancer
:wq!
# ansible-playbook balancer.yml --syntax-check

I think the syntax looks good, but double-check the hostnames!

Just a heads up, make sure the roles are correctly defined in your Ansible config.

Wait, does it really switch between nodes like that? Sounds too good to be true.

This playbook sets up load balancing between web servers.

I remember we had to check the syntax with ansible-playbook before running it. I hope I don't forget that step during the exam!

I'm a bit confused about the output requirements. Do we need to specify the exact IP addresses in the playbook, or will it automatically resolve them?

I practiced a similar question where we had to set up a load balancer, and I think we used a similar structure for the playbook. Just need to make sure the roles are correctly referenced.

I think I remember that we need to define the plays for both the balancer and webservers groups, but I'm not entirely sure about the syntax for including roles.

This seems like a good opportunity to demonstrate my Ansible skills. I'll make sure to thoroughly test the playbook before submitting it, and double-check that the output matches the expected results for both the balancer and webserver hosts.

Okay, I think I've got a good handle on this. The key is creating the balancer.yml file with the two plays - one for the balancers host group using the balancer role, and one for the webservers host group using the phphello role. I'll just need to make sure the roles are set up correctly and the playbook runs without any syntax errors.

This looks like a pretty straightforward Ansible playbook question. I think I can handle this - I'll just need to create the balancer.yml file with the two plays as described, and make sure the roles are set up correctly.

Hmm, I'm a little unsure about the specifics of the balancer role and how to configure the load balancing between the webservers. I'll need to review the details carefully and make sure I understand how to properly implement that functionality.

Haha, 'Welcome to node3.example.com on 192.168.10.z'? I hope the actual IP address is a little more specific than that!

I like the way the playbook is structured, with separate plays for the balancers and webservers. It makes it easy to understand the different components being configured.
