Error trying run react Docker image on k8s

Question

I'm building a Micro-services E-commerce project, I need to create a docker image for each server in my project and run them inside K8s cluster. After successfully creating images for all back-end server I tried creating a docker image for my React front-end app, every time I try creating the image this error happened.

Here is my docker configuration:

FROM node:alpine
WORKDIR /src
COPY package*.json ./
RUN npm install --silent
COPY . .
CMD ["npm ","start"];

Here is the error:

Error: Cannot find module '/src/npm '
    at Function.Module._resolveFilename (node:internal/modules/cjs/loader:933:15)
    at Function.Module._load (node:internal/modules/cjs/loader:778:27)
    at Function.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:79:12)
    at node:internal/main/run_main_module:17:47 {
  code: 'MODULE_NOT_FOUND',
  requireStack: []
}

Sometimes it throws an error like this:

webpack output is served from content not from webpack is served from content not from webpack is served from /app/public docker

The extra space solved half of the problem but the image didn't work, the next error is still there. — Imran Abdalla, Aug 03 '21 at 22:23
Hello @ImranAbdalla. Could you tell us which version of react-scripts are you using? — Wytrzymały Wiktor, Aug 04 '21 at 08:28
I've made some research and found two possible solutions: 1. Add `stdin_open: true` to your docker-compose. 2. Downgrade your `react-scripts` to v3.4.0. Please try them in that order and let me know about the results. — Wytrzymały Wiktor, Aug 05 '21 at 11:20
The server ran, I added stdin: true to my k8s deployment config and downgraded my react-scripts, but I can't not access it on my browser. — Imran Abdalla, Aug 08 '21 at 11:35
Hello @ImranAbdalla. One note: you need to add `stdin_open: true` to your docker-compose file, not your deployment. See [this](https://stackoverflow.com/a/39150040/11560878) as a reference. — Wytrzymały Wiktor, Aug 09 '21 at 08:25
