Automation Demo Script

Prepare for the demos

  • Bring up Vagrant Ubuntu VM
  • Log into default Vagrant account
  • Set up the environment
. /vagrant/install/.prompt
. .aws/setup

Create a single object (VPC)

In the first set of examples we're creating a single object (VPC) to illustrate the check-before-creating concept.

CLI

Execute in CLI directory

less steps/10-create-vpc.sh
steps/10-create-vpc.sh
steps/10-create-vpc.sh
aws ec2 describe-vpcs
aws_vpc
aws_vpc --output table

Ansible

Execute in Ansible directory

cat steps/20-create-vpc.yaml
ansible-playbook steps/20-create-vpc.yaml
ansible-playbook steps/20-create-vpc.yaml -e state=absent
export ANSIBLE_STDOUT_CALLBACK=yaml
ansible-playbook steps/20-create-vpc.yaml -v

CloudFormation

Execute in CloudFormation directory

aws_vpc
cat steps/20-create-vpc.yaml
aws cloudformation create-stack --stack-name test --template-body file://steps/20-create-vpc.yaml
aws cloudformation describe-stacks
aws cloudformation wait stack-create-complete
aws_vpc
aws ec2 describe-vpcs
aws cloudformation delete-stack --stack-name test

Create Object Hierarchy

In the second set of examples we're creating an object hierarchy to illustrate the following workflow:

  • Check whether an object exists
  • Get the ID of the parent object
  • Create an object using parent object ID

CLI

Execute in CLI directory

less steps/20-create-subnet.sh
steps/20-create-subnet.sh
steps/10-create-vpc.sh
steps/20-create-subnet.sh

Ansible

Prepare for demo in Ansible directory

export ANSIBLE_STDOUT_CALLBACK=yaml
ansible-playbook steps/21-create-subnets.yaml -e state=absent
ansible-playbook steps/20-create-vpc.yaml

Execute in Ansible directory

cat steps/21-create-subnets.yaml
ansible-playbook steps/21-create-subnets.yaml -v
ansible-playbook steps/21-create-subnets.yaml -e state=absent

CloudFormation

Execute in CloudFormation directory

aws cloudformation create-stack --stack-name test --template-body file://steps/21-create-subnets.yaml
aws cloudformation describe-stacks
aws cloudformation delete-stack --stack-name test
