You can use YAML anchor feature to set a variable that you can use in a job scripts.

.get_version: &get_version
  - "export SERVICE_VERSION=$(cat package.json | grep version | head -1 | awk -F: '{ print $2 }' | sed 's/[\",]//g' | tr -d '[[:space:]]')"
  - "Current version is: $SERVICE_VERSION"

and then somewhere in script part:

.gitlab-ci.yml:

  variables:
    CONTAINER_NAME: myService
  script:
    - echo "My own script"
    - *get_version
    - docker build --iidfile imageid.txt --cache-from $CONTAINER_NAME:$SERVICE_VERSION -t $CONTAINER_NAME:$SERVICE_VERSION .
    - docker push $CONTAINER_NAME:$SERVICE_VERSION
