Get value of package.json in gitLab CI YML

I'm using gitLab CI for my nodejs application. In my YML file I need to call a script to build a docker image. But instead of using latest I need to use the current version of the project.

This version value can be find in the package.json file of the repository.

Is it possible to read the version value of the package.json file to replace latest by the current version?

# ...
variables:
  CONTAINER_RELEASE_IMAGE: $CI_REGISTRY_IMAGE:latest         # need version value instead of latest 

build:
  stage: build
  script:
    # ...
    - cd /opt/core/bundle && docker build -t $CONTAINER_RELEASE_IMAGE .
    - docker push $CONTAINER_RELEASE_IMAGE

If you are not against installing additional packages you can use jq which allows for much more flexibility (available in repository for both Ubuntu and Alpine). Once you install it (for example apt-get update && apt-get install -yqq jq on Ubuntu):

- export VERSION=$(cat package.json | jq -r .version)
- cd /opt/core/bundle && docker build -t $CI_REGISTRY_IMAGE:$VERSION .
- docker push $CI_REGISTRY_IMAGE:$VERSION

variables:

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

in your job or template

.package-template: &package_template 
image: docker-hub.registry.integ.fr.auchan.com/docker:latest
stage: package 
tags: 
  - stocks
script:
  - export VERSION= ``eval $PACKAGE_VERSION``
  - echo "======> Getting VERSION:  $VERSION" `

You might not be able to do this purely in the gitlab.yml unfortunately, you could create a shell script as follows and check this into your source control

#!/bin/sh
args=("$@")
CI_REGISTRY_IMAGE=${args[0]}

PACKAGE_VERSION=$(cat package.json \
| grep version \
  | head -1 \
  | awk -F: '{ print $2 }' \
  | sed 's/[",]//g' \
  | tr -d '[[:space:]]')
CONTAINER_RELEASE_IMAGE=$CI_REGISTRY_IMAGE\:$PACKAGE_VERSION
cd /opt/core/bundle && docker build -t $CONTAINER_RELEASE_IMAGE .
docker push $CONTAINER_RELEASE_IMAGE

Then execute this script with the argument of $CI_REGISTRY_IMAGE in gitlab.yml

# ...
build:
  stage: build
  script:
    # ...
    - chmod +x script.sh
    - ./script.sh $CI_REGISTRY_IMAGE

To the best of my knowledge this should work for you.

Thank you to DarrenN and dbaba on Github for his package.json version extract shell function
