Sample template for Ansible hosts file for Lab 9
Assuming Elisa, Miriam, Eric, Stephen, and Joseph are five of the students in the OPS435 class in different sections and each one of them was assign a VM in myvmlab with the following information:
- Section A
- Miriam: port 7694 on myvmlab.senecacollege.ca
- ELisa: port 7697 on myvmlab.senecacollege.ca
- Section B
- Eric: port 7811 on myvmlab.senecacollege.ca
- Stephen:port 7850 on myvmlab.senecacollege.ca
- Joseph: port 7874 on myvmlab.senecacollege.ca
The following Ansible inventory file simple called "hosts" can be created and used for the "ansible" command by a regular user on matrix. You can put this inventory file in ~/ops435/lab9 directory.
# This is a template for creating an inventory for the ansible or # ansible-playbook command in matrix. You need to add your VM # information under the appropriate section: [ops435a], [ops435b], etc. instructor ansible_host=myvmlab.senecacollege.ca ansible_port=7001 [ops435a] miriam ansible_host=myvmlab.senecacollege.ca ansible_port=7694 elisa ansible_host=myvmlab.senecacollege.ca ansible_port=7697 [ops435b] eric ansible_host=myvmlab.senecacollege.ca ansible_port=7811 stephen ansible_host=myvmlab.senecacollege.ca ansible_port=7850 joseph ansible_host=myvmlab.senecacollege.ca ansible_port=7874
