I’m new to docker and I wonder that, can I use the docker as an application environment only?
I have the
Dockerfile which let me build a Docker image and let other team-mates and server able to run my project.
FROM node:10.15.3 ADD . /app/ WORKDIR /app RUN npm install RUN npm run build ENV HOST 0.0.0.0 ENV PORT 3000 EXPOSE 3000 CMD ["npm", "run","start"]
The project can be built and ran. All the thing is perfect.
However, I found that all the files will be zip into the image files. My source code and all node_modules. It makes the files too big.
And I remember that in my previous project, I will create the Linux VM and bind my project folder to the guest OS. Then I can keep developing and using the vm as a server.
Can docker do something like this? The docker only needs to load my project folder (which will pass the path when running the command).
Then it runs
npm start/dev. All the library will save into my local directory. OR I run the
npm start manually then the docker load my files and host.
I just need docker to be my application server to make sure I can get the same result like deployed to the Production server.
Can Docker do this?
