"Cannot GET /" error when running angular application on docker container

Question

I'm trying to run a Angular App on docker, but when I try to access some page, I get this error.

I've tried to change the aot to false at angular.json, but it didn't work.

Here is my Dockerfile:

WORKDIR /usr/src/app
COPY package*.json ./
RUN npm install -g @angular/cli
RUN npm install
COPY . ./
RUN npm run build
EXPOSE 8080
CMD [ "node", "server.js" ]

and here is my package.json:

{
    "name": "app-name",
    "version": "0.0.2",
    "scripts": {
        "ng": "ng",

}

If anyone has already faced this error and knows how to solve it, I would greatly appreciate it, thanks.

The ng build command generates a /dist folder. Are you accounting for that? — MikeOne

I solved the problem using the useHash: true on my app-routing.module.ts.

Now I got link like something.com/#/someParameter

@NgModule({
    imports: [RouterModule.forRoot(routes, {relativeLinkResolution: 'legacy', useHash: true})],
    exports: [RouterModule]
})
export class AppRoutingModule {
}
