I have a simple express app I am attempting to deploy on GKE.

When I build and run locally, everything is running as expected.

When I deploy via kubectl on GKE however, I get..

sh: 1: babel: not found
npm ERR! code ELIFECYCLE
npm ERR! errno 1
npm ERR! express-api@1.0.0 prestart: `npm run -s build`
npm ERR! Exit status 1
npm ERR!
npm ERR! Failed at the express-api@1.0.0 prestart script.
npm ERR! This is probably not a problem with npm. There is likely additional logging output above.
npm WARN Local package.json exists, but node_modules missing, did you mean to install?

My deployement yaml file is as follows..

apiVersion: extensions/v1beta1

My Dockerfile looks like..

FROM node:carbon
RUN npm install -g pm2
WORKDIR /usr/src/app
COPY package*.json ./

ARG TARGET_ENV
COPY .env.$TARGET_ENV .env

COPY . .
EXPOSE 8080
CMD [ "npm", "start"]

My Package.json has the following scripts..

  "scripts": {
    "test": "cross-env NODE_ENV=test nodemon --exec mocha ./**/*.spec.js --compilers js:babel-core/register",
    "dev": "cross-env NODE_ENV=dev nodemon -w src --exec \"babel-node src --presets env,stage-0\"",
    "build": "babel src -s -D -d dist --presets env,stage-0",
    "start": "cross-env NODE_ENV=production pm2-runtime dist",
    "prestart": "npm run -s build",
    "clean": "rimraf dist/",
    "build:dev": "bash scripts/build-dev.sh",
    "deploy:dev": "bash scripts/deploy-dev.sh"
  },

And I have the following dependencies..

  "dependencies": {
    "babel": "^6.23.0",
    "babel-cli": "^6.26.0",
    "babel-core": "^6.26.3",
    "babel-preset-env": "^1.6.1",
    "babel-preset-stage-0": "^6.24.1",
    "body-parser": "^1.18.2",
    "cors": "^2.8.4",
    "cross-env": "^5.1.4",
    "dotenv": "^5.0.1",
    "express": "^4.16.3",
    "helmet": "^3.12.0"
  },
  "devDependencies": {
    "chai": "^4.1.2",
    "mocha": "^5.1.1",
    "morgan": "^1.9.0",
    "nodemon": "^1.17.3",
    "rimraf": "^2.6.2",
    "supertest": "^3.0.0"
  }

I also have a bash script set up to handle the deploy for, which looks like..

if [ -z "$1" ]; then
  echo "Missing version / tag"
  exit
fi

echo "Deploying $1"
docker build --build-arg TARGET_ENV=dev -t pggriff/express-api:$1 . &&
gcloud config set project foo-project &&
gcloud container clusters get-credentials dev-cluster --zone europe-west4-a &&
gcloud docker -- push pggriff/express-api:$1 &&
kubectl apply -f deployment.dev.yaml
