Red Hat Enterprise Linux Automation with Ansible
Ansible variables help you reuse values across files in an entire Ansible project.
You can define variables for hosts and host groups in the inventory file.
You can define variables for plays and tasks in the playbook or in external files.
Extra variables are defined on the command line and take precedence over all other variables.
You can use the
registerkeyword to capture the output of a command in a variable.Ansible Vault provides one way to protect sensitive data, such as password hashes and private keys that are used by your Ansible Playbooks.
Ansible facts are variables that Ansible automatically discovers from a managed host.

I am doing the self-paced course RH294 . With two exercises (Ch.3 final Lab and Ch.4 lab exercise 2) I ran into this problem:after installing and starting a web service, from the classroom web termicaI I cannot reach servera.lab.example.com with curl: "No route to host". This despite the fact that I can ping it, open a shell to it, and install the package on it with Ansible.Anyone else have the same problem?What might be the cause?
