Training environment for WWT ACI University students. It creates a virtual machine with Ansible installed along with a sample playbook, Jinja template and XML file to create a tenant in an ACI fabric and add subnets to a bridge domain.
Create a directory called aci-university, enter it, and use an editor to place the contents of the Vagrantfile from https://github.com/joelwking/aci-university to a work directory on your laptop. If you have git installed on your laptop, you can create a work directory, enter it and clone the repository.
git clone https://github.com/joelwking/aci-university.git
Issue the command vagrant up to bring up the virtual machine, then vagrant ssh to logon.
Enter the working directory:
cd aci-university/ansible/playbooks/
Modify the inventory file and to reference your training ACI fabric name or IP address
sudo vi hosts
Modify the passwords.yml file to use your training fabric username and password
sudo vi passwords.yml
Encrypt the passwords.yml file
sudo ansible-vault encrypt passwords.yml
sudo cat passwords.yml
Review the playbook
sudo vi jinja2_loop.yml
Review the Jinja template file in ./templates
cat ./templates/*
Review the XML file used to create the tenant
cat ./files/*
Run the playbook to create a tenant and update the subnets in the bridge domain, you will be prompted for the vault password used to encrypt the file.
sudo ansible-playbook jinja2_loop.yml --ask-vault
The output should look like the following:
Vault password:
