Angular in Docker

VirtualHost

Apache allows virtual host configuration to be bound on ports and manage configuration for domain requests using ServerName and ServerAlias directives. A default virtual host configuration has been added below and works well to serve Angular output.

<VirtualHost *:80>

    ServerAdmin engineering@wearewiser.com

    DocumentRoot /usr/local/apache2/htdocs

    <Directory /usr/local/apache2/htdocs>
        Options -Indexes +FollowSymLinks +MultiViews
        AllowOverride All
        Order allow,deny
        allow from all
    </Directory>

    # Logs for local development only!
    # CustomLog /var/log/apache/access.log combined
    # ErrorLog /var/log/apache/error.log

</VirtualHost>

VirtualHost default configuration

SPA Configuration

Apache responds for requests to unresolved resources with a 404 response. This does not work well with SPAs, which implement routing on the client-side. To fix this, a .htaccess file is required.

<IfModule mod_rewrite.c>
  RewriteEngine On
  RewriteBase /
  RewriteRule ^index\.html$ - [L]
  RewriteCond %{REQUEST_FILENAME} !-f
  RewriteCond %{REQUEST_FILENAME} !-d
  RewriteRule . /index.html [L]
</IfModule>

src/.htaccess

The configuration required to make SPA work with non-root route paths.

In order to add the .htaccess file into the compiled output, it must be added as an asset in the angular.json file. Update the projects.mylounge.architect.build.assets array by adding src/.htaccess. Update the value with the core application name configured in your angular.json file. Now, npm run build will load this file into the dist output.

Dockerfile

Below is an example of a sensible Dockerfile. Update the value with the core application name configured in your angular.json file.
