如何使用elasticsearch启动quarkus原生应用？

我已经部署了第一个Quarkus应用程序作为Docker容器，其中包含hibernate-orm-panache、resteasy-reactive、postgresql等。Quarkus应用程序作为容器连接到本地机器上的PostgreSQL，并且运行得非常好。在第二个版本中，我想用它额外实现ElasticSearch，它在开发模式下运行得非常好。
现在我面临着将quarkus-app和elasticsearch作为容器部署的困难。我试着在服务器上以dev模式正常运行它，它工作得很好。在创建了原生包，创建了Docker映像，最后将该映像作为容器运行后，我得到了一个错误消息Elasticsearch request failed:Connection refused.
属性文件如下所示：

quarkus.datasource.db-kind=postgresql
quarkus.datasource.username=postgres
quarkus.datasource.password=postgrespw
quarkus.datasource.jdbc.url=jdbc:postgresql://192.168.5.45:5432/b2data

#quarkus.hibernate-orm.log.sql=true

quarkus.hibernate-search-orm.elasticsearch.version=7
quarkus.hibernate-search-orm.automatic-indexing.synchronization.strategy=sync

quarkus.elasticsearch.hosts = localhost:9200
#quarkus.elasticsearch.port = 9200
#quarkus.elasticsearch.devservices.enabled = false

我也试过以localhost：9200的身份启动elasticsearch-cluster，然后连接 quarkus ，但不幸的是没有成功。我是 quarkus 的新手，尤其是elasticsearch。我知道我遗漏了一些东西，所以有人能帮我弄清楚吗？

我们遗漏了最重要的信息：您是如何启动应用程序容器和Elasticsearch容器的？
默认情况下，一个容器不会“看到”另一个容器在本地主机上运行;您需要配置网络并使用正确的主机名来引用其他容器。
如果您是docker的新手，我建议您阅读文档（从overview of networking开始）。
但简而言之，更简单的解决方案是创建一个自定义网桥网络，然后在该网络中运行所有内容：

docker network create my-net

# Run postgres
# WARNING: in a real-world scenario you should configure named volumes or mounts,
# to properly persist data.
# See https://docs.docker.com/storage/
docker run --name mypostgres --network my-net \
  -e POSTGRES_USER=admin \                                                                    
  -e POSTGRES_PASSWORD=admin \        
  -e POSTGRES_DB=my-db \              
  postgres:14.5

# Run elasticsearch
# WARNING: in a real-world scenario you should configure named volumes or mounts,
# to properly persist data.
# See https://docs.docker.com/storage/
docker run --name myelasticsearch --network my-net \
  --ulimit memlock=-1:-1 --memory-swappiness=0 \                                                                               
  -e "xpack.security.enabled=false" \
  -e "discovery.type=single-node" \
  elastic/elasticsearch:7.17.7

# Run the application,
# passing the connection info as environment variables
docker run --name myapp --network my-net -p 8080:8080 \
  -e QUARKUS_DATASOURCE_JDBC_URL=jdbc:postgresql://mypostgres/my-db \
  -e QUARKUS_DATASOURCE_USERNAME=admin \
  -e QUARKUS_DATASOURCE_PASSWORD=admin \
  -e QUARKUS_HIBERNATE_SEARCH_ORM_ELASTICSEARCH_HOSTS=myelasticsearch:9200 \
  my-app-container-image

您可能希望使用docker-compose将所有配置整齐地存储在一个文件中：https://docs.docker.com/compose/gettingstarted/
