    # The Conductor container does the heavy lifting, and provides a portable

    # from the same distribution as you're building your target containers with.

  # For built services, concatenated with service name to form the built image name.

  # When using the k8s or openshift engines, use the following to authorize with the API.
  # Values set here will be passed to the Ansible modules. Any file paths will be mounted

  #k8s_auth:
    # path to a K8s config file

OS / ENVIRONMENT

Windows 10
Docker version 18.06.0-ce, build 0ffa825
Ansible/Ansible-container running in Docker image `mac89/ansible-container`

SUMMARY

I get the following error the role 'flask' was not found in ./roles:/src/roles:/etc/ansible/roles: when attempting to build the container from within my Docker image mac89/ansible-container. I suspect it has something to do with my running ansible-container from within a Docker image, but I have no idea how to solve it.

Using the steps described here I can use external roles: https://hub.docker.com/r/mac89/ansible-container/

However I cannot use ansible-container install which results in the error container.exceptions.AnsibleContainerGalaxyFatalException: Failed to load container.yml: [Errno 2] No such file or directory: '/src/con tainer.yml'

STEPS TO REPRODUCE

You can reproduce by using my Docker image and adding the volume mapping /var/run/docker.sock:/var/run/docker.sock and executing the commands below.

docker exec -it YOUR_CONTAINER_ID bash
mkdir demo
cd demo
ansible-container init
pico container.yml (add flask role)
ansible-container build

EXPECTED RESULTS

The role to be found and the container to build
