Graylog is a centralized logging solution that allows the user to aggregate and search through logs. It provides a powerful query language, a processing pipeline for data transformation, alerting abilities and much more. It is fully extensible through a REST API. Add-Ons can be downloaded from the Graylog Marketplace.

Take a look at the minimal Graylog architecture to get the big picture of a Graylog setup. In essence, Graylog needs to talk to MongoDB to store configuration data as well as Elasticsearch to store the actual log data.

Please refer to the Graylog Docker documentation for a comprehensive overview and a detailed description of the Graylog Docker image.

Every configuration option can be set via environment variables, take a look here for an overview. Simply prefix the parameter name with GRAYLOG_ and put it all in upper case. Another option would be to store the configuration file outside of the container and edit it directly.

Documentation for Graylog is hosted here. Please read through the docs and familiarize yourself with the functionality before opening an issue on GitHub.
