我正在尝试在docker上运行弹性搜索 我为与mysql容器连接的Rails应用程序构建了一个容器 我想将此Rails容器与弹性容器连接 但是我得到这个错误
无法打开与localhost：9200的TCP连接（无法分配请求的地址-“ localhost”端口9200的connect（2））
当我运行docker-compose up时 这些网址工作正常 http://localhost:3000/
但是我收到了这个网址的错误消息 http://localhost:3000/messages
无法打开与localhost：9200的TCP连接（无法分配请求的地址-“ localhost”端口9200的connect（2））
我想从此网址获得回复 http://localhost:3000/messages
如何打开端口 9200 ??????????????
这是我的docker-compose.yml文件

要扩展@ bjarte-brandt答案，您可以创建一个初始化程序来设置ELASTIC_HOST：
app / config / initializers / elasticsearch.rb：
config = {
host: "http://localhost:9200/"
}
if File.exists?("config/elasticsearch.yml")
config.merge!(YAML.load_file("config/elasticsearch.yml")[Rails.env].deep_symbolize_keys)
end
Elasticsearch::Model.client = Elasticsearch::Client.new(config)
app / config / elasticsearch.yml：
development: &default
host: 'elastic'
test:
<<: *default
production:
<<: *default

docker-compose公开服务“ elastic”。此服务在您的Docker网络中是可解析的，因此您的Rails应用应按以下方式连接：
ELASTIC_HOST: "elastic"
localhost在该容器本地。
答案 2 :(得分：0)
这部分docker会打开相关的端口。
ports:
- "9200:9200"
- "9300:9300"
弹性开始吗？ 请分享：
docker-compose logs elastic
在您的docker-compose上，将弹性主机设置为容器的本地主机，这样它就不能通过端口发布：
transport.host: localhost
将其配置为：
transport.host: "0.0.0.0"
# or even remove it
或通过将其添加到服务中来与docker容器共享网络：
network_mode: "host"
