Invalid mount config for type "bind": source path must be a directory

Error creating inferno_nginx_server_1
I'm trying to start inferno with: docker-compose up

I'm running Docker Engine - Enterprise on Windows Server 2019 standard
I have docker configured to use Linux containers.
I had Inferno working on my own personal machine with Windows 8 and Docker Desktop but now I am attempting to run it on Windows Server 2019 which doesn't seem to support Docker Desktop. Hence, I'm just using Docker Engine and compose from powershell.

Your environment

• Edition of inferno (Community or Program): Whatever edition is here: https://github.com/onc-healthit/inferno/releases/tag/v2.5.0
• Version of inferno: 2.5.0
• Which browser and version(s) is the bug present on?:

Steps to reproduce
When I run docker-compose up I get this error:

Step 4/4 : EXPOSE 4567

Expected behavior
Inferno should start :)

Actual behavior
Error as shown above.

I've been investigating this further. It seems this may be an issue with containers running on Windows. At the very end of this article, the author states:

One quirk remains. You still can't mount a single file as a volume, you'll get invalid mount config for type "bind": source path must be a directory

https://blog.sixeyed.com/what-you-can-do-with-docker-in-windows-server-2019-that-you-couldnt-do-in-windows-server-2016/

The strange thing is that this same docker-compose.yml entry works on my Windows 10 PC:

  nginx_server:
    image: nginx
    volumes:
      - ./deployment-files/nginx.conf:/etc/nginx/nginx.conf:ro
    ports:
      - "8080:80"
    command: [nginx, '-g', 'daemon off;']
    links:
      - ruby_server:ruby_server
    depends_on:
      - ruby_server

[js8080]

I tried working around this by copying the ./deployment-files/nginx.conf from my host machine to the nginx image in the Inferno\Dockerfile:

# added this section to copy nginx.conf instead of overriding it via volume mapping in docker-compose.yml
FROM nginx:latest
COPY ./deployment-files/nginx.conf /etc/nginx/nginx.conf
# end my addition

FROM ruby:2.5

# Install gems into a temporary directory
COPY Gemfile* ./
RUN gem install bundler && bundle install

# Expose the port
EXPOSE 4567

Then in the docker-compose.yml file I commented out the volumes portion of the nginx_server section:

  nginx_server:
    image: nginx
    #volumes:
    #  - ./deployment-files/nginx.conf:/etc/nginx/nginx.conf:ro
    ports:
      - "8080:80"

That got docker-compose up to work but when I browse to http://localhost:8080/ it just shows a generic "Welcome to nginx!" message and not the Inferno-specific page.

Thanks for the report, we will look into this. In the meantime, Inferno can be run in docker without nginx. I don't use windows, so the commands might not be exactly the same, but this is how I would build and run Inferno:

docker build -t inferno .
docker run -p 4567:4567 inferno

If you don't have any local changes you need to include, you can instead download and run a prebuilt image:

docker pull onchealthit/inferno
docker run -p 4567:4567 onchealthit/inferno

After doing one of these, Inferno should be available at localhost:4567.

@Jammjammjamm That worked -- I did the latter and ran the prebuilt image. Thanks!
