Show docker-compose logs upon initialisation failure

[estahn]

Dockerspec Version

0.4.1

Ruby Version

2.4

Platform Details

Mac

Scenario

docker-compose fails to initialise one of the containers

Steps to Reproduce

Use a container that fails to initialise (e.g. busybox with a non-existing command)

Expected Result

dockerspec should fail and provide useful information, e.g. docker-compose logs of the failed container.

Actual Result

Just fails with no specific information.

@estahn as always, thanks for the report :wink:

Please, could you add a complete docker-compose.yml example, the current output and the expected output?

For example, I have tried the following docker-compose.yml:

version: '2'

services:
  busybox:
    image: busybox
    command: badcommand

And the following spec/test_spec.rb file:

require 'dockerspec/serverspec'

describe docker_compose('docker-compose.yml', wait: 5) do
  its_container(:busybox) do
    describe file('/etc/passwd') do
      it { should be_file }
    end
  end
end

The error running docker-compose up:

$ docker-compose up
Creating tmp_busybox_1

ERROR: for busybox  Cannot start service busybox: oci runtime error: container_linux.go:247: starting container process caused "exec: \"badcommand\": executable file not found in $PATH"
ERROR: Encountered errors while bringing up the project.

And dockerspec returns exactly the same error:
