如何使用Makefile正确运行docker

Question

I have a make file:

APP_NAME=sgy-core-bdd/codeception

build: ## Build the container
    docker build -t $(APP_NAME) .

run:
    docker run --entrypoint /bin/bash -i -t -v $(pwd):/app $(APP_NAME)

when i do make run i get this error

make: *** No rule to make target `/app', needed by `run'.  Stop.

How do I resolve this error

Answer 1

Recipe lines must be indented with a real TAB character. In your example, it's likely that line is not indented with a TAB.

That means that this line:

docker run --entrypoint /bin/bash -i -t -v $(pwd):/app $(APP_NAME)

is treated as a make rule, not a recipe, which is the equivalent of writing:

docker: /app $(APP_NAME)
run: /app $(APP_NAME)
--entrypoint: /app $(APP_NAME)
/bin/bash: /app $(APP_NAME)
-i: /app $(APP_NAME)
-t: /app $(APP_NAME)
-v: /app $(APP_NAME)
$(pwd): /app $(APP_NAME)

So when you use make run , it wants to build the prerequisites /app and $(APP_NAME) .
