How can I use Angular 19 SSR with Docker?

I created a fresh Angular 19 SSR app and I would like to use it with Docker.

But I faced a lot of issues.

My Dockerfile :

FROM node:23

WORKDIR /app

COPY package*.json ./

RUN npm install

RUN npm install -g @angular/cli@latest

COPY . .

RUN npm run build:ssr

EXPOSE 4200

CMD ["npm", "run", "serve:ssr"]


Script form package.json

"scripts": {
"ng": "ng",
"build:ssr": "ng build && ng run chapter-alert-front:server",
"serve": "ng serve",
"serve:ssr": "node dist/chapter-alert-front-server/main.js",
"watch": "ng build --watch --configuration development",
"test": "ng test",
"serve:ssr:chapter-alert-front": "node dist/chapter-alert-front/server/server.mjs"
},


My angular.json

With the above code, all work fine but the app doesn't lunch. That look normal because the code just run a node app.js ... Which part I need to change ?

If anyone can please, help me a bit, thanks a lot.
