Linking custom container on wercker

Question

I create a container in docker and with id/name i

box: ujwaldhakal/laravel
build:
  steps:
    - install-packages:
        packages: git
    - script:
        name: install phpunit
        code: |-
          curl -L https://phar.phpunit.de/phpunit.phar -o /usr/local/bin/phpunit
          chmod +x /usr/local/bin/phpunit
    - script:
        name: install composer
        code: curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer
    - script:
        name: install dependencies
        code: composer install --no-interaction
    - script:
        name: PHPUnit integration tests
        code: phpunit --configuration phpunit.xml

box ujwaldhakal/laravel won't work if used php it will work. There were no any good docs for linking the custom container on wercker.

Short Version

Have you tried adding a tag after the box id? That solved the issue for me under similar circumstances. Otherwise the image has not (yet) been built and/or pushed to Docker Hub.

Long Version

I had a similar problem. I wanted to use the dealerdirect/ci-php box

So I changed my wercker.yml to use it:

box:
  id: dealerdirect/ci-php
# ...

But then the build failed:

The "setup environment" step had the error "no such image":

After some experimenting it turned out I needed to add a "tag":

box:
  id: dealerdirect/ci-php:5.6
# ...

After that the docker image was pulled fine and the build continued working again:

Of course, this only works if the images actually exists on Docker Hub. If it does not, you will have to push it manually or set up automated building.
