如何使用 Couchbase 使用不同的端口 Java SDK 3

Question

語境：
我正在使用 docker （使用測試容器）編寫一些集成測試。 我想使用 toxiproxy 連接到 couchbase。

問題：
我無法使用與默認端口不同的端口連接到沙發底座。 文檔說只使用 SeedNode，但它不起作用。

客戶：

<dependency>
    <groupId>com.couchbase.client</groupId>
    <artifactId>java-client</artifactId>
    <version>3.0.5</version>
</dependency>

沙發底座設置：

echo "Initializing new cluster"
docker-compose exec couchbase \
  couchbase-cli cluster-init -c 127.0.0.1 --cluster-username Administrator --cluster-password password \
  --services data,index,query --cluster-ramsize 4096

echo "Creating new bucket"
docker-compose exec couchbase \
  couchbase-cli bucket-create -c couchbase:8091 --username Administrator \
  --password password --bucket default --bucket-type couchbase \
  --bucket-ramsize 1024

有用：

services:
  couchbase:
    image: couchbase:latest
    volumes:
      - .couchbase:/opt/couchbase/var
    ports:
      - "8091:8091"
      - "11210:11210"

SeedNode seedNode = SeedNode.create("127.0.0.1", Optional.of(11210), Optional.of(8091));
ClusterOptions clusterOptions = ClusterOptions.clusterOptions("Administrator", "password");
Cluster cluster = Cluster.connect(Collections.singleton(seedNode), clusterOptions);

Bucket bucket = cluster.bucket("default");
Collection collection = bucket.defaultCollection();

collection.insert("key", "Hello, Couchbase!");

它不起作用：

services:
  couchbase:
    image: couchbase:latest
    volumes:
      - .couchbase:/opt/couchbase/var
    ports:
      - "28091:8091"
      - "21210:11210"

SeedNode seedNode = SeedNode.create("127.0.0.1", Optional.of(21210), Optional.of(28091));

錯誤：
我看到很多警告，例如：

[cb-events] WARN  com.couchbase.endpoint  - [com.couchbase.endpoint][EndpointConnectionFailedEvent][1282us] Connect attempt 7 failed because of AnnotatedConnectException: finishConnect(..) failed: Connection refused: /127.0.0.1:11210 {"bucket":"default","circuitBreaker":"DISABLED","coreId":"0xdf4c6e800000001","remote":"127.0.0.1:11210","type":"KV"}
com.couchbase.client.core.deps.io.netty.channel.AbstractChannel$AnnotatedConnectException: finishConnect(..) failed: Connection refused: /127.0.0.1:11210

它在插入行失敗：

不知何故，使用 CouchbaseContainer 而不是我自己的 docker-compose 它適用於容器的隨機端口，但這對我來說還不夠，因為我想設置 toxiproxy 端口。

這是一個錯誤還是我做錯了什么？

Answer 1

要回答這個問題（但不幸的是，不能解決 OP 的問題），您可以使用 SDK 3 指定一個自定義 KV 端口，如下所示：

 Cluster cluster = Cluster.connect("localhost:12345", username, password);

如果你不知道 KV 端口，你可以像這樣指定一個管理器端口：

 Cluster cluster = Cluster.connect("localhost:45678=manager", username, password);

（作為替代方案，您可以創建SeedNode對象，但我個人覺得這有點麻煩。）

為了使自定義端口工作，您需要使用支持備用地址的 Couchbase Server 6.5 或更高版本，並使用setting-alternate-address命令配置 Couchbase 以使用“外部”地址通告非標准端口。

SDK 使用傳遞給Cluster.connect的地址來引導連接。 一旦它連接到服務器，它就會丟棄你給它的地址，而是使用它從服務器獲得的地址。 服務器需要配置為報告“外部”地址，以便它可以告訴客戶端哪些主機和端口用於未來的請求。
