Sharing the source code with container

EACCES: permission denied, open ‘/app/node_modules/.cache/.eslintcache’

I’m on Ubuntu machine. I’am having trouble running the react app when using code sharing command:

Here is the error in the browser window.
Failed to compile

EACCES: permission denied, open ‘/app/node_modules/.cache/.eslintcache’

Here are the commands I used:
salad@99:/$ docker image build -t react_image:1.0.0 .

salad@99:/ docker run -d -p 2066:3000 -v (pwd):/app --name c10 react_img:1.0.0

salad@99:/$ docker exec -it c10 sh

/app $ ls -l

The source of the problem seems to be the changing user to node instead of user.
I’ve my Dockerfile exact as Mosh’s. What could be the fix?

I had the same on Ubuntu. Switching the user to node worked for me.

So the two last lines of the dockerfile shoud look like :

USER node

CMD ["npm", "start"]

Yeap, everything works well with the DEFAULT user “node”. You don’t even have to set explicitly

I don’t understand properly why we need to switch the app user to node can you please explain it better??

I wanted to give a link of an edited reply to my previous post, but it seems the platform does not allow to editing. Anyways I don’t how the default user “node” is generated but if you want to got by “node” user and figure out the problem later, ignoring user creation is the solution.

FROM node:14.16.0-alpine3.13
RUN mkdir app
WORKDIR /app
.......
....

It’s the default user. You can ignore user creation altogether
