Dockerfile for Elasticsearch

Elasticsearch is a distributed, free and open search and analytics engine for all types of data, including textual, numerical, geospatial, structured, and unstructured.

Elasticsearch is the central component of the Elastic Stack, a set of free and open tools for data ingestion, enrichment, storage, analysis, and visualization.

It is considerably easier and faster to run elasticsearch in a container than to install it on a host server.

1)Create a docker file and add the below contents.

# vim Dockerfile

FROM centos:7
MAINTAINER [e-mail]
RUN useradd -ms /bin/bash elasticsearch
RUN yum -y install java-1.8.0-openjdk-devel
RUN yum -y install wget
RUN wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-5.5.0.rpm
RUN rpm -ivh elasticsearch-5.5.0.rpm
RUN mkdir /usr/share/elasticsearch/config
RUN cp -R /usr/share/elasticsearch/* /home/elasticsearch/
COPY elasticsearch.yml /home/elasticsearch/config/
COPY log4j2.properties /home/elasticsearch/config/
RUN chown -R elasticsearch:elasticsearch /home/elasticsearch/*
WORKDIR /home/elasticsearch
USER elasticsearch
EXPOSE 9200
EXPOSE 9300
CMD ["/home/elasticsearch/bin/elasticsearch"]

elasticsearch.yml and log4j2.properties are the updated files with the configurations needed for our elasticsearch.Place both files in the same directory where dockerfile exists.

2) Build docker image
NB: be in the directory where dockerfile exists
docker build -t elasticsearh .
"elasticsearch is the image name"

3) Create docker container
# docker images #to get the docker image id
# docker run -d -P 9200:9200 -P 9300:9300 --name elastic <image id>

4) check container status
# docker ps

Play with docker🥂
