Deploy your app in a container

For our deployments we use Kubernetes or OpenShift. Everything has to be in a container and be part of a develop / build / deploy pipeline.

In a previous post I already explained how to deploy an Angular app in a Java artifact using a maven structure.

When we want to completely separate the frontend from the backend we have to create multiple containers.

In this example we create a Docker container that contains an Angular application (

The docker container


FROM nginx
COPY nginx.conf /etc/nginx/nginx.conf
COPY ./src/dist /usr/share/nginx/html

We use Nginx as web server for the deployment. In theory an Angular app is a simple Javascript application and it doesn’t need a web server. An online file storage offered by a cloud provider could be enough.

Some advantages of a web server:

Our docker consists in only 3 lines.

FROM nginx we use the nginx Docker image COPY nginx.conf /etc/nginx/nginx.conf we copy our own nginx configuration. COPY ./src/dist /usr/share/nginx/html we copy the prod build of our Angular app.

Nginx configuration

We have a custom configuration for nginx nginx.conf:

events {
  worker_connections  1024;  ## Default: 1024

http {

    ## use mime types
    include /etc/nginx/mime.types;

     server {
        listen 80;

        location / {
            root /usr/share/nginx/html;
            index  index.html;
            ## without this our .css are not loaded
            try_files $uri $uri/ /index.html?$query_string;

    ## enable gzip compression
    gzip on;
    gzip_vary on;
    gzip_min_length 256;
    gzip_proxied any;


This configuration creates a web server that listen port 80, makes a compressions of the response and redirect to the main page if an URL is not found.
