Answer 1

you need to choose an image including docker binaries

image: gitlab/dind

services:
  - docker:dind

Answer 2

additional to Hieu Vo

image: docker:latest

stages:
  - build
  - release

services:
  - docker:dind

Answer 3

Problem here is that node docker image does not embed docker binaries.

Two possibilities :

• split stages to two jobs. One using node images for quality and test, one using docker image for building and deploying. See jobs documentation.

• build a custom docker image that embed both node and docker and use this image to build your repo.

Note that in both case you will have to enable docker inside your agent. See documentation.
