OpsWorks deploy script for multiple instances in a stack. Meant to work with Codeship.

deploy.sh

# Install the aws cli client
pip install awscli

# List instances for a particular stack
OPSWORKS_STACK_ID="XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
OPSWORKS_APP_ID="XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"
OPSWORKS_INSTANCE_LAYER_ID="XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX"

# Deploy the stack and app to instances found above
# This endpoint is only available in `us-east-1` even though
# your application may be hosted in another zone.
#
# Instance state codes can be found here:
#   http://docs.aws.amazon.com/AWSEC2/latest/CommandLineReference/ApiReference-cmd-DescribeInstances.html
