Deploying Elasticsearch, Kibana, and Cerebro with Docker on a Linux Node

This guide demonstrates how to install Docker CE on a CentOS 7 host and use it to deploy Elasticsearch 7.6.1, Kibana 7.6.1, and the Cerebro monitoring UI.

Install Docker CE:

yum -y install docker-ce-20.10.4-3.el7

systemctl start docker

Verify Docker is running and pull the Elasticsearch image:

docker ps -a

docker search elasticsearch

docker pull elasticsearch:7.6.1

docker images

Run Elasticsearch as a single‑node container:

docker run -d --name es2 -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" 41072cdeebc5

docker logs bae2d63e5f47

Prepare a configuration file for Kibana and launch it:

mkdir -p /data/elk

vim /data/elk/kibana.yml

# Example kibana.yml content
server.name: kibana
server.host: "0"
elasticsearch.hosts: [ "http://192.xx.xx.xx:9200" ]
xpack.monitoring.ui.container.elasticsearch.enabled: true

docker run -d --name=kibana --restart=always -p 5601:5601 -v /data/elk/kibana.yml:/usr/share/kibana/config/kibana.yml kibana:7.6.1

docker logs -f kibana

Download and set up Cerebro for Elasticsearch cluster monitoring:

unzip cerebro-0.8.3.zip

ln -s cerebro-0.8.3 cerebro

# Edit /root/cerebro/conf/application.conf
hosts = [
  {
    host = "http://192.xx.xx.xx:9200"
    name = "en-es"
    headers-whitelist = [ "x-proxy-user", "x-proxy-roles", "X-Forwarded-For" ]
  }
]

./cerebro -Dhttp.port=9000 -Dhttp.address=192.xx.xx.xx >/dev/null &

After starting the services, access Kibana at http:// :5601 and Cerebro at http:// :9000 to monitor the Elasticsearch cluster.
