【问题描述】：

我在 Stratoscale 的 Symphony 中有一个 K8S 集群（运行 Linux）。它有一个由 Symphony 分配的集群 IP 地址 IP1。我已经在集群中安装了 Consul。我能够将 Consul KV 密钥“放入”一个 pod（通过 pod 网页上提供的命令行界面）并从另一个 pod 中“获取”它。就端口而言，名为“consul-consul-server”的 K8S Consul 服务具有此规范：

{
  "kind": "Service",
  "metadata": {
    "name": "consul-consul-server",
    "namespace": "consul",
    ...
  },
  "spec": {
    "ports": [
      {
        "name": "http",
        "protocol": "TCP",
        "port": 8500,
        "targetPort": 8500,
        "nodePort": 30323
      },
      {
        "name": "serflan-tcp",
        "protocol": "TCP",
        "port": 8301,
        "targetPort": 8301,
        "nodePort": 31056
      },
      {
        "name": "serflan-udp",
        "protocol": "UDP",
        "port": 8301,
        "targetPort": 8301,
        "nodePort": 31056
      },
      {
        "name": "serfwan-tcp",
        "protocol": "TCP",
        "port": 8302,
        "targetPort": 8302,
        "nodePort": 30717
      },
      {
        "name": "serfwan-udp",
        "protocol": "UDP",
        "port": 8302,
        "targetPort": 8302,
        "nodePort": 30717
      },
      {
        "name": "server",
        "protocol": "TCP",
        "port": 8300,
        "targetPort": 8300,
        "nodePort": 32091
      },
      {
        "name": "dns-tcp",
        "protocol": "TCP",
        "port": 8600,
        "targetPort": "dns-tcp",
        "nodePort": 31688
      },
      {
        "name": "dns-udp",
        "protocol": "UDP",
        "port": 8600,
        "targetPort": "dns-udp",
        "nodePort": 31688
      }
    ],
    "selector": {
      "app": "consul",
      "component": "server",
      "release": "consul"
    },
    "clusterIP": "10.104.86.253",
    "type": "NodePort",
    "externalTrafficPolicy": "Cluster",
  },
  "status": {
    "loadBalancer": {}
  }
}

如何从集群外部的命令行启动 Consul 客户端代理？根据我在https://www.consul.io/docs/agent/cloud-auto-join.html#kubernetes-k8s- 中读到的内容，我尝试了以下方法：

consul agent -retry-join "provider=k8s namespace=consul label_selector=\"app=consul,component=server\" host_network=true" -client= -bind= -join= -config-file=C:\Config\consul.hcl -server-port=32091

还有其他一些组合，但它们都会导致此错误：

==> Starting Consul agent...
==> Error starting agent: 2 errors occurred:
        * listen udp 161.92.250.34:8600: bind: The requested address is not valid in its context.
        * listen tcp 161.92.250.34:8600: bind: The requested address is not valid in its context.

知道我做错了什么吗？提前致谢。

【解决方案1】：

事实证明，我应该以不同的方式调用“consul agent -retry-join”：

consul 代理 --retry-join=:8500 -bind=

这对我有用。
