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

Hello @ImranAbdalla. Could you tell us which version of react-scripts are you using? — Wytrzymały Wiktor

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
