Ansible Docs

Summary

Ansible is used to provision our infrastructure in Azure. Specifically it will ssh into each one of our VMs and run the modules within the ansible playbooks.

Inventory

Our inventory file is located in inventory/myazure_rm.yml. This is a dynamic inventory which means that it will grab a list of the current VMs we have in our azure resource group.

Variables

The vars file in vm_management/vars/vars.yml is used by the notebooks in vm_management. We use the vars file to specify vm hosts and the resource group. The vars file also contains a password which has been encrypted using the command ansible-vault encrypt_string. With ansible-vault, we no longer have to input the password manually every execution.

Usage

To start all VMS:

ansible-playbook ./vm_management/azure-vm-start.yml

To provision all VMs:

ansible-playbook ./vm_provision/azure-vm-provision.yml

Run Simulation on all VMs:

ansible-playbook ./vm_provision/azure-vm-simstart.yml

Stop and delete containers on all VMs:

ansible-playbook ./vm_provision/azure-vm-container-cleanup.yml

Delete docker images on all VMs:

ansible-playbook ./vm_provision/azure-vm-image-cleanup.yml

To stop all VMS:

ansible-playbook ./vm_management/azure-vm-stop.yml
