Test-kitchen is a test harness tool that allows integration testing of configuration and infrastructure.
It has a plug-in architecture and has plugins for both
Cloud Formation and
terraform to create AWS infrastructure. For plugin details see
kitchen-terraform and
kitchen-cloudformation.
awspec is a tool that allows RSpec tests for AWS resources. For plugin details see
kitchen-awspec.
There is a simple example in the kitchen-awspec github repository to demonstrate creating an EC2 instance with cloud formation and then verifying it with awspec. See
https://github.com/neillturner/kitchen-verifier-awspec/tree/master/example
1.
Install test-kitchen as per http://kitchen.ci/docs/getting-started/installing
basically install ruby for your platform
then to install test-kitchen
gem install test-kitchen
and the cloud formation or terraform plugin:
gem install kitchen-cloudformation or gem install kitchen-terraform
and the awspec plugin
gem install kitchen-verifier-awspec
2.
Use git to clone the github kitchen-awspec repository.
git clone https://github.com/neillturner/kitchen-verifier-awspec.git
3.
Run the example on your workstation:
a. Configuration AWS Settings
See
Configuration Settings and Precedence
For example:
# configure aws keys via either a profile
export AWS_DEFAULT_PROFILE=myprofile
# or set keys directly
export AWS_ACCESS_KEY_ID=myaccesskey
export AWS_SECRET_ACCESS_KEY=mysecretkey
# set aws region
export AWS_REGION=eu-west-1
b. Go to example directory
cd kitchen-verifier-awspec/example
c. For windows set the ssl cert file
set SSL_CERT_FILE=C:/repository/kitchen-verifier-awspec/example/ca-bundle.crt
d. Check that everything installed successfully
kitchen list
should return the base-aws instance
e. Create the Cloud Formation stack
kitchen create base-aws -l debug
f. Verify the AWS Resources
kitchen verify base-aws -l debug
g. Delete the Cloud Formation stack
kitchen destroy base-aws -l debug
