The following structure in docker-compose.yaml will allow you to have the Dockerfile in a subfolder from the root:
version: '3'
services:
db:
image: postgres:11
environment:
- PGDATA=/var/lib/postgresql/data/pgdata
volumes:
- postgres-data:/var/lib/postgresql/data
ports:
- 127.0.0.1:5432:5432
**web:
build:
context: ".."
dockerfile: dockerfiles/Dockerfile**
command: ...
...
Then, in your Dockerfile, which is in the same directory as docker-compose.yaml, you can do the following:
ENV APP_HOME /home
RUN mkdir -p ${APP_HOME}
# Copy the file to the directory in the container
COPY test.json ${APP_HOME}/test.json
COPY test.py ${APP_HOME}/test.py
# Browse to that directory created above
WORKDIR ${APP_HOME}
You can then run docker-compose from the parent directory like:
docker-compose -f .\dockerfiles\docker-compose.yaml build --no-cache
