Elasticsearch 5.5 unofficial image

What's inside?

Build the image with docker build -t <yourtag> .. Mount persistent volume at /usr/share/elasticsearch/data. Pay attention to FS permissions when using with Kubernetes. The image is based on Alpine Linux for smaller footprint

This repo also contains example single-file Kubernetes definition to run the image on a cluster and an example config

Why do I use it?

If you ever tried running Elasticsearch from official image on Kubernetes you would probably know the answer. Official image is not flexible for outside modifications. Also, official elastic.co 5.5 images are bundled with X-Pack which is redundant. This image runs the custom docker-entrypoint that copies the config over from /config/elasticsearch.yml before starting the container. If you want to have a flexible Elasticsearch 5.5 image feel free to use this image

How do I run it locally?

Run with docker run -v <path to config>:/config/elasticsearch.yml -p 9200:9200 schikin/elasticsearch:5.5 Check that Elasticsearch is running: curl http://localhost:9200

How do I deploy to Kubernetes?

1. Make sure kubectl is pointing at the right cluster
2. Run kubectl apply -f elasticsearch.yml

This installs Elasticsearch on a kube-system namespace. Best served with docker-filebeat, docker-logstash and docker-kibana for a Kubernetes cluster logging

Make sure you have enough resources on cluster before proceeding. This definition allocates full vCPU to Elasticsearch and 2Gb of RAM (1Gb on-heap and 1Gb for lucene index)
