npm install freezes when using Docker in Docker

Summary

npm install does not work on Gitlab Runner in Kubernetes (deployed with the gitlab/gitlab chart). It freezes and the job time outs.

Steps to reproduce

.gitlab-ci.yml

stages:
  - build

node:
  stage: build
  image: docker
  services:
    - docker:dind
  variables:
    DOCKER_HOST: tcp://localhost:2375
    DOCKER_TLS_CERTDIR: ""
  script:
    - docker build -t node node

Dockerfile

FROM node:13-alpine

WORKDIR /app
RUN npm install --verbose express
COPY . .

CMD [ "npm", "start" ]

Actual behavior

The job freezes when it comes to npm install. The command works fine outside of DIND. The Docker image is built successfully on Docker Desktop and Ubuntu 19.10.

Expected behavior

NPM should install the packages.
