Makefile for using ansible-playbook to do syntax checking for YAML playbooks

makefile

# Collect top-level YAML files under plays/ folder
# e.g. plays/upgrade_ansible_tower/upgrade_ansible_tower.yml
# These should only be Ansible playbook files 
# i.e. store includes in child includes/ dir
playbooks := $(wildcard plays/*/*.yml)

# Check YAML syntax using ansible-playbook
syntax: $(playbooks)
	@GREEN='\033[0;32m'; \
	NC='\033[0m'; \
	echo "$${GREEN}Checking syntax with ansible-playbook$${NC}"

	@# Execute ansible-playbook against each file
	@$(foreach playbook, $^, ansible-playbook $(playbook) --syntax-check; )
