Get value of package.json in gitLab CI YML

Question

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 curren

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
