rchaser53 commented 6 years ago

i want to use environment variable to post the message to slack. so i add the environment variable like below in Makefile.

docker:
    docker run --rm\
        -e SlackUrl=$(SlackUrl)\
        -e HANDLER=$(HANDLER)\
        -e PACKAGE=$(PACKAGE)\
        -e GOPATH=$(GOPATH)\
        -e LDFLAGS='$(LDFLAGS)'\
        -v $(CURDIR):$(CURDIR):Z\
        $(foreach GP,$(subst :, ,$(GOPATH)),-v $(GP):$(GP)):Z\
        -w $(CURDIR)\
        eawsy/aws-lambda-go-shim:latest make -f $(MAKEFILE) all

and use like below. but get empty.

url := os.Getenv("SlackUrl")  // url is ""

how should i do?

Hi @rchaser53,

In order to use environment variables inside your Lambda code, you don't have to do anything special. You just have to configure your Lambda function (by cli or by the web console). So do not modify your Makefile.
