# Makefile 經驗分享 @mileschou --- ## 這是一個建置工具 --- ## 簡單的格式 ```makefile foo.txt: echo "foo" > foo.txt bar.txt: echo "bar" > bar.txt ``` ---- ```bash make foo.txt make bar.txt ``` --- ## 應用實例 ```makefile build: docker build -t=seagon . shell: docker run --rm -it seagon sh run: docker run --rm -it -p 8000:80 seagon ``` --- ## 試試看？ ```bash touch build make build ``` --- ## PHONY 用法 1 ```makefile .PHONY: build build: docker build -t=seagon . ``` --- ## PHONY 用法 2 ```makefile SLEEP = 1 2 3 4 5 go: @for sec in $(SLEEP); do \ echo $$sec; \ done ``` ---- ## PHONY 用法 2 ```makefile SLEEP = 1 2 3 4 5 .PHONY: go $(SLEEP) go: $(SLEEP) $(SLEEP): @sleep $@ && echo $@ ``` PS：文件有提到定義 PHONY 有助於效能提升 --- ## 依賴的表達方式與應用 ```makefile test: vendor php vendor/bin/phpunit vendor: composer.phar php composer.phar install composer.phar: curl -sS https://getcomposer.org/installer | php ``` ---- ``` bash make test ``` ---- ```makefile test: .env php vendor/bin/phpunit .env: vendor cp .env.example .env php artisan key:generate vendor: composer.phar php composer.phar install composer.phar: curl -sS https://getcomposer.org/installer | php ``` --- ## 變數應用 1 ```makefile ENV := dev STACK := sso: aws sso --profile ${ENV} login AWS_PROFILE=${ENV} deploy: cdk deploy --profile ${ENV} --context ENV=${ENV} ${STACK} ``` ---- ```bash make sso make sso ENV=prod make deploy ENV=prod make deploy ENV=prod STACK=AuthStack ``` --- ## 變數應用 2 ```makefile IMAGE := $(shell basename $(shell pwd)) VERSION := latest build: docker build -t=$(IMAGE):$(VERSION) . ``` --- ## 變數應用 3 ```makefile IMAGE := $(shell basename $(shell pwd)) COMPOSER_PATH := $(shell which composer) ifdef COMPOSER_PATH GITHUB_TOKEN := $(shell composer config -g github-oauth.github.com) endif image: ifdef GITHUB_TOKEN docker build --tag=$(IMAGE) --build-arg GITHUB_TOKEN=${GITHUB_TOKEN} . else @echo ">>> Please pass the env var"; @exit 1 endif ``` --- ## 完整應用範例 --- ## 參考資料 - [官方網站](https://www.gnu.org/software/make/manual/html_node/)
