graylog2-docker

Debian-based, self-contained graylog2 image. Can run standalone or backed by an existing elasticsearch cluter.

Using It

To get started quickly with an embedded elasticsearch instance, do this:

docker run -d -p 9000:9000 -p 514:514 -p 12201:12201 jamescarr/graylog2-docker

To get it rolling with an existing elasticsearch cluster

docker run -d -p 9000:9000 -p 514:514 -p 12201:12201 -e ES_CLUSTER_NAME=<cluster_name> -e ES_CLUSTER_HOSTS=cluster01:9300,cluster02:9300 jamescarr/graylog2-docker

The username/password to the web interface is admin/admin. You can override the password with the GRAYLOG2_ADMIN_PASSWORD environment variable.

Configuration

Environment Variables

• ES_CLUSTER_NAME - the name of the elasticsearch cluster this graylog2 instance should join
• ES_CLUSTER_HOSTS - comma separated string of host/port combinations that graylog2 should attempt to connect to. This will get plugged into elasticsearch_discovery_zen_ping_unicast_hosts in the graylog2.conf
• CORS_ENABLED - Enable CORS
• GRAYLOG2_ES_PLUGINS - comma separated list of elasticsearch plugins to include. Will install on first run. (e.g. GRAYLOG2_ES_PLUGINS=elasticsearch/elasticsearch-cloud-aws/1.6.0,lmenezes/elasticsearch-kopf/0.9.0)
• GRAYLOG2_ADMIN_PASSWORD - Sets the admin password for graylog2, must already be sha256 hashed. Do this in a console: echo $(echo -n clever | sha256sum | awk '{print $1}')
• GRAYLOG2_ADMIN_USER - Sets the admin password for graylog2
• GRAYLOG2_REST_TRANSPORT_URI - sets the rest_transport_uri

Graylog Elasticsearch Configuration

You can also define any number of vairables to tune the definition of the embedded graylog2 elasticsearch instance as well. These are defined with the prefix gec. and written when the elasticsearch configuration file is generated.

For example, say we want to enable the http interface, host it on port 9500 and specify the plugin path:

-e gec.http.port=9500 -e gec.http.enabled=true -e gec.path.plugins=/opt/graylog2-server/plugins

This will generate the following configuration file:

http.enabled: true
http.port: 9500
path.plugins: /opt/graylog2-server/plugins
