I’ve been trying to host an angular app on nginx with docker during this past week but i couldnt get through it.
This is mi dockerfile:

your textFROM node:latest as build your textWORKDIR /usr/local/app your textCOPY ./ /usr/local/app/ your textRUN npm install your textRUN npm install -g @angular/cli your textCMD [“npm”, “start”] your textFROM nginx:latest your textRUN rm /usr/share/nginx/html/* your textCOPY –from=build /usr/local/app/dist/prueba /usr/share/nginx/html your textRUN rm etc/nginx/conf.d/default.conf your textCOPY default.conf /etc/nginx/conf.d/ your textEXPOSE 80

this is my default.conf file:
your textserver {
your textlisten 80;
your textserver_name app;
your textlocation / {
your textproxy_pass http://localhost:4200;
your textproxy_http_version 1.1;
your textproxy_set_header Upgrade $http_upgrade;
your textproxy_set_header Connection ‘upgrade’;
your textproxy_set_header Host $host;
your textproxy_cache_bypass $http_upgrade;
your text}
}
