This is using Python 2. It is recommended to run this package in a virtual environment.

1. Open Terminal application

2. Change to home directory

cd

3. Install virtual environment package (if not installed )

virtualenv --version

If the command is not recognized, install virtualenv with the following instructions, else go to step 4.

sudo pip install virtualenv

4. Check your default version of Python

python --version

5. Create a virtual environment with python 2.7

virtualenv aci-workshop --python=/usr/bin/python2.7

6. Activate the virtual environment

source aci-workshop/bin/activate

7. Clone "aci_workshop_code_samples" repository

git clone https://github.com/CiscoDevNet/aci_workshop_code_samples.git

8. Change directory

cd aci_workshop_code_samples

9. Install requirements

pip install -r requirements.txt

10. Install Ansible

pip install ansible==2.7.8

11. Download Cobra SDK egg files

THIS STEP HAS ALREADY BEEN DONE FOR YOU:

Download cobra eggs:

cd $HOME/Downloads
wget https://www.dropbox.com/s/koiljhrra16g30o/acicobra-3.2_7f-py2.7.egg
wget https://www.dropbox.com/s/esohbv25bwtoj68/acimodel-3.2_7f-py2.7.egg

The 2 egg files have been placed in your Downloads directory

12. Change directory

cd $HOME/Downloads

13. Install Cisco APIC Python SDK - acicobra egg file

easy_install -Z acicobra-3.2_7f-py2.7.egg

14. Install Cisco APIC Python SDK - acimodel egg file

easy_install -Z acimodel-3.2_7f-py2.7.egg

15. Test APIC Access

Browse to your APIC simulator: https://<ip address> and login

Create a Unique Tenant

16. In Terminal, return to "aci_workshop_code_samples" directory

cd $HOME/aci_workshop_code_samples

17. Open the file "tenant_create.yml" using Atom

atom tenant_create.yml

18. Make these changes to the file: tenant_create.yml

Verify or make changes to insure these fields are as noted:

	aci_hostname:  <your APIC simulator>
	tenant:        <your unique tenant name>
	description:   <some description>

SAVE YOUR CHANGES - click on File, click on Save

19. Return to command line and execute the Playbook

ansible-playbook tenant_create.yml

20. Verify tenant was created in Web UI

  Browse to your APIC simulator: https://<ip address> and login

Run the Ansible Playbook to create ACI Firewall Config

21. In Terminal, change directory to aci_workshop_code_samples/playbook_vars/aci_workshop_fab1

cd $HOME/aci_workshop_code_samples/playbook_vars/aci_workshop_fab1

22. Open the file "aci_fw_config_vars.yml" using Atom

atom aci_fw_config_vars.yml

23. Modify this file: aci_fw_config_vars.yml

Note: this is the input variable file for the Playbook we will run later.

Verify or make changes to insure these fields are as noted:

	aci_hostname:  <your APIC simulator>
	aci_tenant:    <your unique tenant name>

SAVE YOUR CHANGES - click on File, click on Save

24. In Terminal, change directory to aci-workshop

cd $HOME/aci_workshop_code_samples

25. Return to command line and execute the Playbook

ansible-playbook run_firewall_build_demo.yml -e @./playbook_vars/aci_workshop_fab1/aci_fw_config_vars.yml

26. Login to APIC to Verify/Monitor changes within your tenant's Networking section

	Browse to your APIC simulator: https://<ip address> and login

Security Policy Configuration

27. Change to python_scripts directory

cd $HOME/aci_workshop_code_samples/python_scripts

28. Open the file "policy_cfg_source.yml" using Atom

atom policy_cfg_source.yml

29. Modify this file: policy_cfg_source.yml

Verify or make changes to insure the tenant name is correct:

	tenants:
      -
        name: "<this is YOUR tenant you just created>"

SAVE YOUR CHANGES - click on File, click on Save

30. Return to command line, and view the Python script options

python policy_cfg.py -h

31. Execute the python script

33. Login to APIC to Verify/Monitor changes within your tenant's Contract section

	Browse to your APIC simulator: https://<ip address> and login

Time Permitting: Fabric Discovery

33. Change to python_scripts directory

cd $HOME/aci_workshop_code_samples/python_scripts

34. Return to the command line, and view the Python script options

python fabric_site_specific.py -h

35. Execute the python script

python fabric_site_specific.py -a <your apic> -u admin -p <password> -f fabric_site_acisim.yml
