Docker image pull (elasticsearch)

docker network create elastic

docker pull docker.elastic.co/elasticsearch/elasticsearch:8.5.3

docker run -d --name es01 --net elastic -p 9200:9200 -p 9300:9300 -it docker.elastic.co/elasticsearch/elasticsearch:8.5.3

# Port 9200 is used for all API calls over HTTP. This includes search and aggregations, monitoring and anything else that uses a HTTP request. All client libraries will use this port to talk to Elasticsearch

# Port 9300 is a custom binary protocol used for communications between nodes in a cluster. For things like cluster updates, master elections, nodes joining/leaving, shard allocation

깔끔하게 설치되면 좋겠지만 역시나 몇가지 문제가 발생했다.

발생한 error 1.

• ERROR: [1] bootstrap checks failed. You must address the points described in the following [1] lines before starting Elasticsearch.
• SOLVED: 공식 설치가이드를 확인하면 최대 map-count를 조정하라는 말이 나온다. https://www.elastic.co/guide/en/elasticsearch/reference/8.2/vm-max-map-count.html

발생한 error 2.

• ERROR: cannot find tty
• SOLVED: https://github.com/docker/for-mac/issues/4822

docker run -it --privileged --pid=host debian nsenter -t 1 -m -u -n -i sh
sysctl -w vm.max_map_count=262144

want to use docker vm ..!

• https://github.com/docker/for-mac/issues/4822

• 결국 Colima를 사용해 설치완료!

docker version
>   OS/Arch:           darwin/amd64    
    Context:           colima           -> 사용중인 context는 colima(not docker-desktop)
    Experimental:      true

# 복구는 docker context use default

여기까지 진행했다면,

When you start Elasticsearch for the first time, the following security configuration occurs automatically:

Certificates and keys are generated for the transport and HTTP layers. The Transport Layer Security (TLS) configuration settings are written to elasticsearch.yml. A password is generated for the elastic user. An enrollment token is generated for Kibana.

인 상황

백그라운드 실행시 비번 안보이는 현상

• docker logs 로 다시 봐도 안보임

https://github.com/elastic/elasticsearch/issues/85047

docker exec -ti es01 /usr/share/elasticsearch/bin/elasticsearch-reset-password -u elastic
docker exec -ti es01 /usr/share/elasticsearch/bin/elasticsearch-create-enrollment-token -s kibana

pw : pUrzSGapSbFklBWGloQT

Docker image pull (kibana)

docker pull docker.elastic.co/kibana/kibana:8.5.3
docker run --name kib-01 --net elastic -p 5601:5601 docker.elastic.co/kibana/kibana:8.5.3

이후 logstash 설치

docker pull docker.elastic.co/logstash/logstash:8.5.3
