+# Docker images
+
+Use `nikic/scalar_objects` with docker
+
+# Steps
+
+1. Build your image
+```shell
+$ docker build -t php-scalar-objects ./8.1-alpine
+```
+
+2. Create a docker file for your projects
+
+Example `Dockerfile`
+```dockerfile
+FROM php-scalar-objects
+COPY . /usr/src/myapp
+WORKDIR /usr/src/myapp
+CMD [ "php", "./index.php" ]
+```
+
+Example `index.php`
+```php
+<?php
+
+class StringHandler
+{
+    public static function length($self)
+    {
+        return strlen($self);
+    }
+
+    public static function startsWith($self, $other)
+    {
+        return strpos($self, $other) === 0;
+    }
+}
+
+register_primitive_type_handler('string', 'StringHandler');
+
+$string = "abc";
+var_dump($string->length()); // int(3)
+var_dump($string->startsWith("a")); // bool(true)
+```
+
+3. Build your project
+
+```shell
+$ docker build -t my-php-app .
+```
+
+> Execute this in the same directory where your app is
+
+4. Run your app
+
+```shell
+$ docker run -it --rm --name my-php-running-app my-php-app:latest
+```
