⚠️ You must rebuild the stack images with docker-compose build whenever you switch branch or update the Overriding the ES_HEAP_SIZE and LS_HEAP_SIZE environment variables has no effect on the heap size used by Elasticsearch and Logstash (see issue #129). Create an index pattern via the Kibana API: The created pattern will automatically be marked as the default index pattern as soon as the Kibana UI is opened for the The following commands will generate a private key and a 10-year self-signed certificate issued to a server with hostname elk for the Beats input plugin: As another example, when running a non-predefined number of containers concurrently in a cluster with hostnames directly under the .mydomain.com domain (e.g. For a sandbox environment used for development and testing, Docker is one of the easiest and most efficient ways to set up the stack. To avoid issues with permissions, it is therefore recommended to install Elasticsearch plugins as elasticsearch, using the gosu command (see below for an example, and references for further details).

If you're using Docker Compose to manage your Docker services (and if not you really should as it will make your life much easier! To run cluster nodes on different hosts, you'll need to update Elasticsearch's /etc/elasticsearch/elasticsearch.yml file in the Docker image so that the nodes can find each other: Configure the zen discovery module, by adding a discovery.zen.ping.unicast.hosts directive to point to the IP addresses or hostnames of hosts that should be polled to perform discovery when Elasticsearch is started on each node. If you cannot use a single-part domain name, then you could consider: Issuing a self-signed certificate with the right hostname using a variant of the commands given below. Let's assume that the host is called elk-master.example.com. The Elastic Docker registry contains Docker images for all the products in the Elastic Stack: https://www.docker.elastic.co/. Logstash's settings are defined by the configuration files (e.g. In order to entirely shutdown the stack and remove all persisted data, use the following Docker Compose command: ℹ️ Refer to How to disable paid features to disable authentication. In version 5, before starting Filebeat for the first time, you would run this command (replacing elk with the appropriate hostname) to load the default index template in Elasticsearch: In version 6 however, the filebeat.template.json template file has been replaced with a fields.yml file, which is used to load the index manually by running filebeat setup --template as per the official Filebeat instructions. CLUSTER_NAME: the name of the Elasticsearch cluster (default: automatically resolved when the container starts if Elasticsearch requires no user authentication). Older major versions are also supported on separate branches: Clone this repository onto the Docker host that will run the stack, then start services locally using Docker Compose: You can also run all services in the background (detached mode) by adding the -d flag to the above command. ; not elk1.subdomain.mydomain.com, elk2.othersubdomain.mydomain.com etc. A few extensions are available inside the extensionsdirectory. click Create index pattern and return to the Discover view to inspect your log entries.
