First things first. Let’s check the directory structure of the app.
A Full Stack MEVN Application
Let’s take a look into the DB image first.

I thought importing dump data should be working if I used CMD or ENTRYPOINT.
It didn’t work though. So I picked a solution using exec and shell script. It’s in the last part. 😉
Now, let’s check the Express.js backend server image.

RUN npm install
CMD ["node" , "index.js" ]
Pretty simple, isn’t it? 😉
Let’s move on. Frontend time.

You know what? Too much complicated? 😉 This is not a raw development server, but a production server.
But this is not the best way to deploy Vue apps, better solution is to separate the building stage using node docker image, and also need some hack in nginx configuration in case you use history mode .
Finally, let’s check our docker-compose.yml file.

Now, here comes the shell script named “db-init.sh” for importing db dump.

Need to be careful to the last tag “–jsonArray”.
When should it be there?
Literally, it should be there when the data is json array, not an object.
Alright, now let’s get the whole app up and running with these commands:

docker-compose up -d
docker exec -it mongo-container sh /app/db-init.sh
Awesome! We got the entire app containerized.
Happy coding! 🙂
