Graylog Docker Compose files

Introduction

This is a set of Docker Compose files that allow you to quickly spin up a Graylog instance for testing or demo purposes.

Prerequisites

• Docker
• Docker Compose

Configure your OS

Make sure to configure your OS or Docker to have the correct vm.max_map_count setting, see: OpenSearch Docs

Configure Graylog

All the Graylog configurations can be set via environment variables. Just prefix the parameter name with GRAYLOG_ and put it in upper case.

There is an environment file (.env.example) where you can store these environment variables. Rename this to .env so Docker Compose will pick it up.

  cp .env.example .env

Important: Be sure to to set the GRAYLOG_PASSWORD_SECRET and GRAYLOG_ROOT_PASSWORD_SHA2 environment variables in the .env file! Graylog won't start without these.

Starting Graylog

After you've configured GRAYLOG_PASSWORD_SECRET and GRAYLOG_ROOT_PASSWORD_SHA2, run these commands to start the instance:

docker compose up

To start it daemonized, run:

docker compose up -d

Default client port is 9000. So now you can navigate to http://localhost:9000.

Login:

  admin

Password:

If you're running the DataNode and it's the initial startup, use

  password from the logs of your first graylog node

as the password for the basic auth dialog to access the preflight/configuration UI. Use

  <your password from GRAYLOG_ROOT_PASSWORD_SHA2>

after you configured graylog. If you have manually configured graylog to connect to OpenSearch directly, use

  <your password from GRAYLOG_ROOT_PASSWORD_SHA2>

because the preflight/configuration UI will not be shown.
