无头服务的未解决地址

Question

我已经在rke2 kube linux发行版上安装了centos8，节点是这样的：

NAME                           STATUS   ROLES                       AGE    VERSION
a4b-kube-1.acme.com   Ready    control-plane,etcd,master   167m   v1.22.5+rke2r1
a4b-kube-2.acme.com   Ready    control-plane,etcd,master   161m   v1.22.5+rke2r1
a4b-kube-3.acme.com   Ready    control-plane,etcd,master   158m   v1.22.5+rke2r1

到目前一切尚好。当我试图用舵安装卡夫卡时，问题就来了。

Values.yaml:

kafka:
  replicaCount: 1
  clusterDomain: acme-kube.local
  zookeeper:
    replicaCount: 3
    clusterDomain: acme-kube.local
    heapOpts: -Xmx128m -Xms128m
  heapOpts: -Xmx256m -Xms256m

requirements.yaml

dependencies:
- name: kafka
  repository: https://charts.bitnami.com/bitnami
  version: 12.18.3

Chart.yaml

apiVersion: v1
appVersion: "1.0"
description: A Helm chart test for acme
name: acme-test
version: 0.0.1

在创建了名为acme-default的命名空间之后，使用这些命令部署kafka：

helm dependency update acme-test/
helm --namespace=a4b-test install acme-test acme-test/

豆荚现在是这样的：

NAME                          READY   STATUS             RESTARTS        AGE
acme-test-kafka-0       0/1     CrashLoopBackOff   7 (4m46s ago)   18m
acme-test-zookeeper-0   0/1     CrashLoopBackOff   8 (101s ago)    18m
acme-test-zookeeper-1   0/1     CrashLoopBackOff   8 (68s ago)     18m
acme-test-zookeeper-2   0/1     CrashLoopBackOff   8 (52s ago)     18m

卡夫卡走错了，因为动物园是错误的，这里卡夫卡的日志：

无法解决地址的错误:acme-测试-动物园管理员:2181 (org.apache.zookeeper.client.StaticHostProvider) java.net.UnknownHostException: acme-test-动物饲养员: java.base/java.net.Inet6AddressImpl.lookupAllHostAddr(Native方法不知道的名称或服务)java.base/java.net.InetAddress.getAllByName0(InetAddress.java:1509)，java.base/java.net.InetAddress.getAllByName(InetAddress.java:1368)，java.base/java.net.InetAddress.getAllByName(InetAddress.java:1302)，org.apache.zookeeper.client.StaticHostProvider$1.getAllByName(StaticHostProvider.java:92)，org.apache.zookeeper.client.StaticHostProvider.resolve(StaticHostProvider.java:147)，org.apache.zookeeper.client.StaticHostProvider.next(StaticHostProvider.java:375)在org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1137) 2022-01-14 16:41:27,145对服务器acme-测试动物园管理员警告会话0x0 :2181，意外错误，关闭套接字连接并尝试重新连接(org.apache.zookeeper.ClientCnxn) java.lang.IllegalArgumentException:无法规范化地址acme测试动物园:2181，因为它不能在org.apache.zookeeper.SaslServerPrincipal.getServerPrincipal(SaslServerPrincipal.java:39) at org.apache.zookeeper.ClientCnxn$SendThread.startConnect(ClientCnxn.java:1087) at org.apache.zookeeper.ClientCnxn$SendThread.run(ClientCnxn.java:1139)上解析

而zookeper的日志是：

其他两个饲养员的吊舱也有同样的错误。我不明白为什么它不能解决，也许库贝安装有什么问题？我的config.yaml是：

server: https://a4b-kube-1.acme.com:9345
token: xxxx
write-kubeconfig-mode: "0644"
tls-san:
  - "acme.com"
cluster-cidr: "10.42.0.0/16"
service-cidr: "10.43.0.0/16"
cluster-dns: "10.43.0.10"
cluster-domain: "acme.com"

Answer 1

在动物园管理员部分，您还必须添加clusterDomain: acme-kube.local
