Question 85035 in Docker Question posted in
The official documentation can be found here.

Is there a better way to copy files and folders to a docker container?

This is what I came up with but it seems clunky to me. Is there a way to streamline the COPY command? Note that not all the folders need to copied.

I did check out Docker’s documentation regarding, and it seems like this may be the only way? I was just checking if anyone else had a brighter idea. Thanks!

# Copy files to container
COPY src/ /opt/build_area/src/
COPY public/  /opt/build_area/public/
COPY app.js doc* .en* tag-push.sh react-0.3.1.tgz package.json .npmrc /opt/build_area/

This is the folder structure:

$ tree -L 1
.
├── .dockerignore
├── .env
├── .env.development
├── .git/
├── .gitignore
├── .npmrc

    This is what I came up with helpful comments from @TahaNaqvi and @DavidMaze. This is much easier to read.

    # Copy files to container
WORKDIR /opt/build_area/

COPY src/ ./src/
COPY public/  ./public/

COPY app.js           
     .npmrc           
     doc* .en*        
     tag-push.sh      
     package.json     
     react-0.3.1.tgz  /opt/build_area/

    dockerignore file can be used just like gitignore file. You can specify files folders to be ignored which will not be copied by COPY command. More doc here – https://docs.docker.com/engine/reference/builder/#dockerignore-file
