如何编写 Docker 文件并为 Rails 服务器编写

Question

i'm newbie to Docker. I have a web app which is written in react js. It contains rails(sqlite3) server to store the data. I have file structure as follows:

  Project:
    1.Front end: dockerfile1, .dockerignore1
    2.Back end: docker file2 , .dockerignore2
    3.Dockercompose.yml

dockerfile1:

 # Stage 1
 FROM node:8 as react-build
 WORKDIR /app
 COPY . ./
 RUN yarn
 RUN yarn build

# Stage 2 - the production environment
FROM nginx:alpine
COPY nginx.conf /etc/nginx/conf.d/default.conf
COPY --from=react-build /app/build /usr/share/nginx/html
EXPOSE 80
CMD ["nginx", "-g", "daemon off;"]

.dockerignore1

.git
 node_modules
 build

Then I have created the container1: $ docker build. -t container1 When i run '$ docker run -p 8000:80 container1' & when i give ' http://localhost:8000 ' on browser, it displays front end page.

I don't know how to write the dockerfile2 for rails server which has sqlite3 database. Then I should write docker compose file.Someone please help me to write docker compose file for communicate between web app and rails server. Thanks in advance.
