1. 部署

不用改变参数，直接安装就行了

2. 部署情况

部署以后，各个模块的数据

应用：

服务：

这里有2个服务：consul-headless/consul-ui, consul-headless是主服务，后面测试会用到

工作负载：

容器：

3. 测试

在 KubeSphere 上搭建的 Consul 集群，可以使用以下方式测试是否正常工作：

3.1. 创建测试pod

apiVersion: v1
kind: Pod
metadata:
  name: consul-client
spec:
  containers:
  - name: consul-client
    image: consul:1.10.2
    command: [ "sleep", "3600" ]
    imagePullPolicy: IfNotPresent
  restartPolicy: Never

将该文件保存为 consul-client.yaml，然后使用以下命令创建一个名为 consul-client 的测试 Pod：

kubectl apply -f consul-client.yaml -n  beta-api

创建以后：

看到容器起来了

3.2. 连接到 Consul Agent

使用以下命令进入测试 Pod 的 shell：

kubectl exec -it consul-client -n <consul-namespace>— /bin/sh

在测试 Pod 的 shell 中运行以下命令连接到 Consul Agent：

consul agent -node=client-1 -join=<consul-server-service-name>.<consul-namespace>.svc.cluster.local:8301 -data-dir=<data-dir>

将 <consul-datacenter> 替换为 Consul 集群的数据中心名称，<consul-server-service-name> 替换为 Consul Server 的 Service 名称，<consul-namespace> 替换为 Consul 集群所在的命名空间。<data-dir> 替换为本地目录的路径

如果 Consul Agent 成功连接到 Consul Server，将显示类似以下的输出：

bash-5.1# kubectl exec -it consul-client -n beta-api -- /bin/sh
/ #
/ # consul agent -node=client-1 -join=consul-headless.beta-api.svc.cluster.local:8301 -data-dir=.
==> Starting Consul agent...
           Version: '1.10.2'
           Node ID: 'ae7758b6-d1f5-8c25-a2c9-83b9ecfaf64f'
         Node name: 'client-1'
        Datacenter: 'dc1' (Segment: '')
            Server: false (Bootstrap: false)

      Cluster Addr: 172.31.26.83 (LAN: 8301, WAN: 8302)
           Encrypt: Gossip: false, TLS-Outgoing: false, TLS-Incoming: false, Auto-Encrypt-TLS: false

==> Log data will now stream in as it occurs:

这意味着 Consul Agent 已经成功连接到 Consul Server，并且正在运行。

3.3. 使用 Consul KV 存储进行测试

再建立一个连接到consul-client那个容器

在测试 Pod 的 shell 中运行以下命令，使用 Consul KV 存储写入一个键值对：

consul kv put foo bar

然后，可以使用以下命令从 Consul KV 存储中读取该键值对：

consul kv get foo

将输出 bar，表示键 foo 的值为 bar。

这样就完成了 Consul 集群的测试。如果以上步骤中任何一步出现问题，请检查相应的命令参数是否正确，并确保 Consul 集群已经正常运行。

bash-5.1# kubectl exec -it consul-client -n beta-api -- /bin/sh
/ #
/ # consul kv put foo bar
'Success! Data written to: foo
/ # consul kv get foo
bar
/ #
