React docker run test stuck on Queued forever

I’m trying to test a new react project repository and the test stuck on ‘Queued’.
This is my .travis.yml:

sudo: required 
services:
    - docker

before_install:
    - docker build -t vinovero/docker-react-test -f Dockerfile.dev .

script:
   - docker run -e CI=true vinovero/docker-react-test npm run test

Please help.
