I have this file (.npmrc.docker)
//registry.npmjs.org/:_authToken=${NPM_TOKEN}
And in my Docker file I have
ARG NPM_TOKEN
RUN mv .npmrc.docker .npmrc
RUN yarn install
However when I run my Docker build with
NPM_TOKEN=mySecretToken docker build .
I get this error
#41 0.710 error An unexpected error occurred: "Failed to replace env in config: ${NPM_TOKEN}".
What’s the proper way to pass an environment variable into my Docker build?
CodePudding user response:
docker build --build-arg NPM_TOKEN=mySecretToken .
should do the job
