The present project is based on the work of Paulo Pires, thus is highly recommended to review his project and his documentation at https://github.com/pires/kubernetes-elasticsearch-cluster also because I do not provide the entire documentation. The Paulo Pires documentation applies to this project too.

• Support for X-Pack plugin: At this moment the image that Paulo Pires uses does not support X-Pack.
• Support for default plugins: At this moment the image that Paulo Pires uses is very minimalist. He disabled the default plugins, but this project does not.
• A new Dockerfile is created based in the official image docker.elastic.co/elasticsearch/elasticsearch:6.1.1, thus it can be easier to migrate to a new elasticsearch version.

• I am not incorporating the ability of SHARD_ALLOCATION_AWARENESS because it is not necessary for my needs, but you can incorporate it easily review the Paulo documentation https://github.com/pires/docker-elasticsearch#environment-variables

• At this moment I am not implementing the version Statefulset for k8s
• I Added a new environment variable ${LICENSE} inside elasticsearch.yml to support self_generated license at this moment if you no provide your own the default is basic.
• The image is created to work with kubernetes but if you want to execute it with docker run, you must comment the ENV DISCOVERY_SERVICE elasticsearch-discovery inside docker file visit https://github.com/pires/docker-elasticsearch to see how to run it.

cd docker
docker build --tag=k8s/elasticsearch:6.1.1 .

cd kubernetes
kubectl create -f elasticsearch-discovery-svc.yaml
kubectl create -f elasticsearch-svc.yaml
kubectl create -f elasticsearch-master.yaml
kubectl rollout status -f elasticsearch-master.yaml
kubectl create -f elasticsearch-client.yaml
kubectl rollout status -f elasticsearch-client.yaml
kubectl create -f elasticsearch-data.yaml
kubectl rollout status -f elasticsearch-data.yaml
