EZP_TEST_REST_HOST environment variable not set

[SalvatorePollaci]

It's impossible to run EzPublishRestBundle functional tests, as the client which executes http requests obtains the http host from environment variable 'EZP_TEST_REST_HOST', which should have value 'nginx'.

Solution: Edit docker-compose.yml to include the 'EZP_TEST_REST_HOST' environment variable with value 'nginx' as so:

version: '2.1'
services:
    ...
    engine:
        ...
        environment:
            ...
            - EZP_TEST_REST_HOST=nginx
