Tinkering with Elasticsearch and Kibana - on Docker, of course

In order to get to grips with the new world of event emission from IBM BPM, I needed to have a combined Elasticsearch / Kibana runtime to which to … emit events.

Using this as source: -

Elasticsearch and Kibana in one container

Simple and lightweight docker image for previewing Elasticsearch and Kibana.

I downloaded the repository file from here, expanded the resulting ZIP file: -

unzip ~/Downloads/nshou-elasticsearch-kibana-e07aa6ed04af.zip 

switched to the appropriate directory: -

cd ~/nshou-elasticsearch-kibana-e07aa6ed04af

took a quick look at the Dockerfile: -

cat Dockerfile

FROM openjdk:jre-alpine

LABEL maintainer "nshou <nshou@coronocoya.net>"


RUN apk add --quiet --no-progress --no-cache nodejs wget \
 && adduser -D elasticsearch

USER elasticsearch

WORKDIR /home/elasticsearch

RUN wget -q -O - https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-${ES_VERSION}.tar.gz \
 |  tar -zx \
 && mv elasticsearch-${ES_VERSION} elasticsearch \
 && wget -q -O - https://artifacts.elastic.co/downloads/kibana/kibana-${KIBANA_VERSION}-linux-x86_64.tar.gz \
 |  tar -zx \
 && mv kibana-${KIBANA_VERSION}-linux-x86_64 kibana \
 && rm -f kibana/node/bin/node kibana/node/bin/npm \
 && ln -s $(which node) kibana/node/bin/node \
 && ln -s $(which npm) kibana/node/bin/npm

CMD sh elasticsearch/bin/elasticsearch -E http.host= --quiet & kibana/bin/kibana --host -Q

EXPOSE 9200 5601

and then created the image: -

docker build -t elastic-search-kibana:elastickib .

and then connected to Kibana: -

and to Elasticsearch: -

which is nice

I'm now following this: -

and will go ahead and setup my BPM 8.6 VM … 

Let's see how I get on …
