Elasticsearch 클러스터와 Kibana를 Docker를 사용하여 실행하는 방법(elasticsearch cluster)

Elasticsearch 클러스터와 Kibana를 Docker를 사용하여 실행하는 방법(elasticsearch cluster)

1. Docker 설치

Docker를 설치합니다. Docker를 설치하려면 Docker 공식 웹사이트에서 설치 지침을 따릅니다.

2. Elasticsearch Docker 컨테이너 실행

Docker Network 생성

docker network create esnet

node-1 컨테이너 실행

docker run -it --name node-1 --net esnet -p 9200:9200 -p 9300:9300 -e ES_JAVA_OPTS="-Xms1g -Xmx1g" docker.elastic.co/elasticsearch/elasticsearch:8.2.1

-> Elasticsearch security features have been automatically configured!
-> Authentication is enabled and cluster connections are encrypted.

->  Password for the elastic user (reset with `bin/elasticsearch-reset-password -u elastic`):
  qZPJKJmczwVYO65nn3bS

->  HTTP CA certificate SHA-256 fingerprint:
  b66b85d14985b710514652839d9905355da94a554e27677cac0ec2801dc4a597

->  Configure Kibana to use this cluster:
* Run Kibana and click the configuration link in the terminal when Kibana starts.
* Copy the following enrollment token and paste it into Kibana in your browser (valid for the next 30 minutes):

-> Configure other nodes to join this cluster:
* Copy the following enrollment token and start new Elasticsearch nodes with `bin/elasticsearch --enrollment-token <token>` (valid for the next 30 minutes):

  If you're running in Docker, copy the enrollment token and run:
  `docker run -e "ENROLLMENT_TOKEN=<token>" docker.elastic.co/elasticsearch/elasticsearch:8.2.1`
