 Run the following command. Make sure to replace `YOUR_ACCESS_KEY_HERE` and `YOUR_SECRET_ACCESS_KEY_HERE` with your own specific keys.
 
 ```console
 docker run --rm -p 4317:4317 -p 55681:55681 -p 8889:8888 \

-Currently the `aws-sdk-call` option is commented out. This is due to dependency conflicts between AWS and the PHP Library. If you would like to enable it, follow the instructions in the comments of the SampleApp1.php file.
