ELK Stack Using Docker Compose

The Elastic stack version 7.0.0 using Docker Compose and the official (OSS) images from Elastic:

• https://github.com/elastic/elasticsearch-docker
• https://github.com/elastic/logstash-docker
• https://github.com/elastic/kibana-docker

See https://www.elastic.co/blog/elastic-stack-7-0-0-released for more info about the features of 7.0.0.

What's in the box?

A docker-compose.yml file, defining:

• 2 Elasticsearch master nodes
• 1 Elasticsearch slave (data/ingest) node
• Logstash
• Kibana

Configuration files for each type of service.

Usage

Clone this repo and run docker-compose up. Watch it unfold, and hopefully you should be able to access the cluster at localhost:5601 through Kibana.

Scaling

Seems to be a bit shaky, but you should be able to scale the slave (data, ingest) nodes using docker-compose scale. For example, if you want 3 slave nodes, write docker-compose scale elasticslave=3.

I have yet to find an easy way to scale the master nodes using Docker Compose without everything breaking.

Other Projects

This project is by far the only one to attempt a Docker Compose setup for the Elastic stack. Here are a few notewothy projects:

• https://github.com/deviantony/docker-elk Is excellent and very well documented. It is easy to get started and configure/scale, but it does not yet work on ELK version 7.0.0.

• https://github.com/spujadas/elk-docker Works with ELK 7.0.0, but by default runs everything inside a single Docker container from a customly built image. Documentation is thorough.

Thus this project was made. I wanted my images to be as close to the official builds as possible, and make it easy to scale using docker-compose. I find it to fit neatly between the two projects. But there is no documentation. Can't have it all, now can we?
