[BUG] Failed to start locally build Docker image

[devaskim]

Describe the bug I made this PR #913 and built Docker container to test

export GW_DOCKER_TAG=3.2 && \
docker build -t devaskim/tb-gateway:$GW_DOCKER_TAG docker/ && \
docker push devaskim/tb-gateway:$GW_DOCKER_TAG

Docker Compose configuration is official.

Here is what I got

admin-docker@test:~/gateway$ docker-compose up
[+] Running 1/0

Hi @devaskim, under the docker folder have to be all gateway files.

[devaskim]

Thanks @samson0v Is it enough to move Dockerfile to root project directory instead of copying all files to docker subdirectory? It would be great to have corresponding documentation section to avoid extra questions.

[samson0v]

@devaskim, we will mention it in the documentation.

[devaskim]

Great, I suggest to close this ticket after docs will be added ;)

[samson0v]

Docs updated

Using docker build . -f docker/Dockerfile will build success.
