docker檢視elaticsearch映象

sudo docker images

配置elasticsearch的對映目錄

sudo mkdir -p /elasticsearch/config
sudo mkdir -p /elasticsearch/data
sudo chmod -R 777 /elasticsearch/
sudo echo "http.host: 0.0.0.0">>/elasticsearch/config/elasticsearch.yml
 

docker啟動elasticsearch

sudo docker run --name elasticsearch -p 9200:9200 \
 -p 9300:9300 \
 -e "discovery.type=single-node" \
 -e ES_JAVA_OPTS="-Xms64m -Xmx128m" \
  -v /elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml \
 -v /elasticsearch/data:/usr/share/elasticsearch/data \
 -v /elasticsearch/plugins:/usr/share/elasticsearch/plugins \
 -d elasticsearch:7.7.0
 

引數說明:

--name elasticsearch：將容器命名為 elasticsearch
-p 9200:9200：將容器的9200埠對映到宿主機9200埠
-p 9300:9300：將容器的9300埠對映到宿主機9300埠，目的是叢集互相通訊
-e "discovery.type=single-node"：單例模式
-e ES_JAVA_OPTS="-Xms64m -Xmx128m"：配置記憶體大小
-v /elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml：將配置檔案掛載到宿主機
-v /elasticsearch/data:/usr/share/elasticsearch/data：將資料資料夾掛載到宿主機
-v /elasticsearch/plugins:/usr/share/elasticsearch/plugins：將外掛目錄掛載到宿主機(需重啟)
-d elasticsearch:7.7.0：後臺執行容器，並返回容器ID
