title: Popup menu doesnt work when dockerized
body: <p>I have a very strange issue. I have an angular app using a p-menu from Primeng for a popup menu in a row of a p-table. </p>
  
  <p>All works fine when I run my app with ng serve. But unfortunately the popup menu doesnt show up anymore when I dockerize my app. Everything else is working find - only my p-menu doesnt show up anymore!</p>
  
  <p>Any idea?</p>
  
  <p>Her my docker file:</p>
  
  <pre><code>FROM node:8.11.3 as node
  
  WORKDIR /app
  
  COPY package.json /app/
  
  RUN npm install
  COPY ./ /app/
  
  ARG env=prod
  
  RUN npm run build --prod --environment $env
  
  FROM nginx:latest
  
  VOLUME ["/usr/share/nginx/html","/etc/nginx/sites-enabled", "/etc/nginx/certs", "/etc/nginx/conf.d", "/var/log/nginx", "/var/www/html"]
  
  WORKDIR /etc/nginx
  
  COPY --from=node /app/dist/ /usr/share/nginx/html
  
  RUN rm /etc/nginx/conf.d/default.conf
  COPY ./nginx-custom.conf /etc/nginx/conf.d/default.conf
  
  EXPOSE 80
  CMD ["nginx", "-g", "daemon off;"]
  </code></pre>
  
  <p><strong>Update:</strong> After upgrading my angular project with npm update --save also running my app with ng serve doest work anymore. Seems docker already used new sources and therefore the issue. </p>
  
  <p>Now I have to find out why p-menu from primeng doesnt work anymore in the latest release.</p>
  
  <p><strong>FINAL UPDATE:</strong></p>
  
  <p>The issue was docker used the newest version of the primeng library while I was still one version behind with my development environment. I had some styles in some CSS files which didnt work with primeng and caused an issue in the new version from primeng. </p>
