Graylog Docker image based on Alpine Linux

Graylog

What is Graylog?

Graylog is a centralized logging solution that allows the user to aggregate, process, and search logs. It provides a powerful query language, a processing pipeline for data transformation, alerting capabilities, and much more. It is fully extensible through a REST API and a plugin interface. Plugins, content packs, and other add-ons can be downloaded from the Graylog Marketplace.

Configuration

Every configuration setting of the Graylog configuration file can be set via environment variables by adding the GRAYLOG_ prefix and using upper case.

Examples:

• password_secret → GRAYLOG_PASSWORD_SECRET
• rest_listen_uri → GRAYLOG_REST_LISTEN_URI

Alternatively the configuration file at /opt/graylog/config/graylog.conf can be replaced by a customized version of this file.

Mandatory settings

There are a few mandatory settings for this Docker image.

• GRAYLOG_PASSWORD_SECRET: A random string being used as password salt or nonce in different parts of Graylog.
• GRAYLOG_ROOT_PASSWORD_SHA2: The SHA-256 hash of the password of the "admin" user in Graylog, default: "admin".

Environment variables (preferred)

This Docker image supports additional environment variables to configure different aspects of Graylog.

• GRAYLOG_NODE_ID: The Graylog node ID. If not provided, Graylog will generate one by itself and save it to /opt/graylog/config/node-id. This can be changed through the GRAYLOG_NODE_ID_FILE environment variable.
• LOG4J: Additional JVM parameters to configure Log4j 2, for example -Dlog4j.configurationFile=/opt/graylog/conf/log4j2.xml for providing a custom Log4j 2 configuration file.
• GRAYLOG_CONF: Path to the Graylog configuration file.

Graylog and Log4j 2 configuration files

This Docker image can optionally be configured by adding a custom Graylog configuration file to /opt/graylog/config or specifically overwrite /opt/graylog/config/graylog.conf and /opt/graylog/config/log4j2.xml.

Persistent data

Graylog only writes data into two locations, which have to be persisted in Docker volumes to survive a container restart:

• /opt/graylog/data/journal: Path to the Graylog disk journal, can be configured with the GRAYLOG_MESSAGE_JOURNAL_DIR environment variable.
• /opt/graylog/config/node-id: The Graylog node ID file, necessary to persist if the GRAYLOG_NODE_ID environment variable is not being used.

graylog died

Hallo!
I'm about to test your container.
build and starts are fine.
After a small konfiguration part, the webinterface is accessable.

i klick a little bit around for an overview an then unfortunately, Graylog dies with this message:
