How to install a plugin for the elasticsearch kubernetes cluster

Question

I have a working kubernetes cluster with the elasticsearch up and running returning a 200. I am trying to install the HQ plugin. So i log into the node running the es-client, and attach to the docker container. When i execute the command

/ # /elasticsearch/bin/plugin  -install royrusso/elasticsearch-HQ

i am getting

Exception in thread "main" java.lang.IllegalArgumentException: Could not resolve placeholder 'DISCOVERY_SERVICE'

I am using the yaml files from here https://github.com/pires/kubernetes-elasticsearch-cluster with these modifications https://github.com/UKHomeOffice/docker-elasticsearch/blob/master/examples/kubernetes.md

Am i missing something?

Thanks in advance

Attach to the container

docker exec -it 9f13966b1201 /bin/sh

Export the DISCOVERY_SERVICE

export DISCOVERY_SERVICE=${DISCOVERY_SERVICE:-elasticsearch-discovery}

Install the Plugin

/elasticsearch/bin/plugin  -install royrusso/elasticsearch-HQ

keep in mind this will not be persistent

Don't you have to restart the service after installing the plugin? – styfle Aug 24 '18 at 17:07
Is service restart required for the plugin changes to be reflected? – Daniccan Oct 29 '19 at 13:53

command: 
            - '/bin/sh'
            - '-c'
            - 'logstash-plugin install logstash-filter-kubernetes && logstash -f /usr/share/logstash/pipeline/logstash.conf'

You can use this in the Deployment|StatefulSet under image section.
