 ### Example: Using localhost
 
-This example creates two services: nginx and redis. When you specify the Docker host port but not the container port, the container port is randomly assigned to a free port. {% data variables.product.prodname_dotcom %} sets the assigned container port in the {% raw %}`${{job.services.<service_name>.ports}}`{% endraw %} context. In this example, you can access the service container ports using the {% raw %}`${{ job.services.nginx.ports['8080'] }}`{% endraw %} and {% raw %}`${{ job.services.redis.ports['6379'] }}`{% endraw %} contexts.
