首先上docker-compose.yaml
version: '2' services: esdev: image: elasticsearch:7.12.0 container_name: esdev environment: - "discovery.type=single-node" - "ES_JAVA_OPTS=-Xmx256m -Xms256m" - "reindex.remote.whitelist=estest:*" volumes: - /opt/docker/elasticsearch/dev/data:/usr/share/elasticsearch/data:rw - /opt/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins - /opt/docker/elasticsearch/dev/logs:/usr/share/elasticsearch/logs ports: - "9200:9200" networks: - mynet estest: image: elasticsearch:7.12.0 container_name: estest environment: - "discovery.type=single-node" - "ES_JAVA_OPTS=-Xmx256m -Xms256m" - "reindex.remote.whitelist=esdev:*" volumes: - /opt/docker/elasticsearch/test/data:/usr/share/elasticsearch/data:rw - /opt/docker/elasticsearch/plugins:/usr/share/elasticsearch/plugins - /opt/docker/elasticsearch/test/logs:/usr/share/elasticsearch/logs ports: - "9201:9200" networks: - mynet networks: mynet: external: true
首先让他们在同一个网络中,然后互相加入白名单whitelist(这里配置的host是容器内的地址,即服务名即可)
启动容器
docker-compose up -d
最后就是复制语句了,这里是从estest,复制到esdev中
curl -X POST "http://localhost:9200/_reindex?pretty" -H 'Content-Type: application/json' -d' { "source": { "remote": { "host": "http://estest:9200" }, "index": "search" }, "dest": { "index": "search" } } '
