Without docker-compose

Application

• Build image with command

./gradlew build
docker build -f docker/Dockerfile -t elk-demo .

Elastic

Pull the image

docker pull docker.elastic.co/elasticsearch/elasticsearch:7.8.1

Kibana

Link: https://www.elastic.co/guide/en/kibana/current/docker.html

Pull the image

docker pull docker.elastic.co/kibana/kibana:7.8.1

Logstash

Links:

• https://www.elastic.co/guide/en/logstash/current/docker.html
• https://www.elastic.co/guide/en/logstash/current/docker-config.html

Pull the image:

How to run

Application

Run the container in the detached mode:

docker run -d --name elk-demo -p 8080:8080 elk-demo:latest

Check application:

curl 192.168.99.100:8080/actuator/health

If the answer is {"status":"UP"} then it's all right.

Elastic

Run the container in the detached mode:

docker run -d --name elastic -p 9200:9200 -p 9300:9300 -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.8.1

Check elasticsearch:

curl -X GET "192.168.99.100:9200/_cat/nodes?v&pretty"

Answer should be like:

ip         heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name
172.18.0.3           33          99   7    0.08    0.24     0.15 dilmrt    *      d052db167119

Kibana

Run the container in the detached mode:

docker run -d --name kibana --link elastic -p 5601:5601 docker.elastic.co/kibana/kibana:7.8.1

Check Kibana via browser: http://192.168.99.100:5601/app/kibana#/home

Logstash

Run the container in the detached mode:

docker run -d --name logstash -e "xpack.monitoring.collection.enabled=false" -e "xpack.monitoring.enabled=false" -e "monitoring.elasticsearch.hosts=http://elastic:9200" -p 5001:5001 -p 9600:9600 docker.elastic.co/logstash/logstash:7.8.1

Check Logstash:

curl 192.168.99.100:9600

The answer should be like

{"host":"8687db32b302","version":"7.8.1","http_address":"0.0.0.0:9600","id":"9aee5549-e6c4-48ff-b8d6-6ffc6195ce8d","name":"8687db32b302","ephemeral_id":"7805affc-4752-41f8-9068-52f2f7710549","status":"green","snapshot":false,"pipeline":{"workers":1,"batch_size":125,"batch_delay":50},"build_date":"2020-07-21T19:19:46+00:00","build_sha":"5dcccb963be4c163647232fe4b67bdf4b8efc2cb","build_snapshot":false}
