Environment variables in circle.yml

Build Environment
1

Hi, I’ve been trying to use environment variables to generalise in our circle.yml but they keep on being printed literally. The below circle.yml illustrates attempting to use a circle ci environment variable directly and another setting up an environment variable for the script in case that caused it to work differently

machine:
  environment:
    PROJECT_NAME: ${CIRCLE_PROJECT_REPONAME}

  services:
    - docker

dependencies:
  override:
    - docker info
    - docker build -t ${PROJECT_NAME}_${CIRCLE_BUILD_NUM} .

test:
    override:
        - docker run --net=host --name ${PROJECT_NAME}_test ${PROJECT_NAME}_${CIRCLE_BUILD_NUM} py.test

deployment:
  dump:
    branch: master
    commands:
      - docker save -o ${CIRCLE_ARTIFACTS}/${PROJECT_NAME}_${CIRCLE_BUILD_NUM}.tar ${PROJECT_NAME}_${CIRCLE_BUILD_NUM}

example output from circle:

$ docker run --net=host --name ${PROJECT_NAME}_test ${PROJECT_NAME}_${BUILD_NUM} py.test

As you can see the variables have not been substituted. All help appreciated.

Turns out it just doesn’t show up in the circleci reporting but exported artifacts are named correctly
