Graylog 6.3.1 on Synology DSM 7.2.2

Below is the Docker Compose script to setup Graylog. Copy and paste this then make a new Project with this script. The default password I used was changeme123 but I strongly encourage you to generate your own SHA256 hash and replace the "GRAYLOG_ROOT_PASSWORD_SHA2" field with it. 

 Once it has been build and is running, you must go into the graylog-1 container and open the log. At the top it should have a randomly generated username and password that is needed for a pre-install configuration page available on port 9000. 

 Note, for this to work on Synology you MUST have this environmental variable as included below:

opensearch.bootstrap.system_call_filter: false
