makefile trickery

makefile

# Example of iterating over a list of projects
projects = $(shell find . -name Dockerfile -exec dirname {} \;)

graceful:
# Find all projects with a Dockerfile, then call the local-stop target
# on them before a vagrant halt. Makes faulty exits more explicit.
	$(foreach p,$(projects), \
		make -i -C $p local-stop ;)
	vagrant halt

# Example of changing a given line of a file
props = ./buildAgent/conf/buildAgent.properties
swap = /tmp/props && mv /tmp/props $(props)

local-build: local-props build

prod-build: prod-props build

# Changes line 8 of the build agent properties file
local-props:
	awk 'NR==8 {$$0="serverUrl=http://192.168.33.10:8111"} 1' $(props) > $(swap)

prod-props:
	awk 'NR==8 {$$0="serverUrl=http://build.example.com:8111"} 1' $(props) > $(swap)
