AWS EKS Consul集成Ingress ALB并连接下游服务的问题可以通过以下步骤进行解决:
其中,使用Consul-Template生成Consul配置的代码示例如下:
apiVersion: v1
kind: ConfigMap
metadata:
  name: my-config
  namespace: default
data:
  consul-template-config.hcl: |
    template {
      source = "/templates/my-template.ctmpl"
      destination = "/consul-config/my-config.hcl"
      command = "consul reload"
    }
通过在templates目录中定义my-template.ctmpl,可以使用Consul-Template即时生成Consul配置。
至于下游服务如何使用Consul进行服务发现和连接Ingress ALB的示例代码如下:
// Connect to Consul agent
    consulConfig := api.DefaultConfig()
    consulClient, err := api.NewClient(consulConfig)
    if err != nil {
        log.Fatal("Error connecting to Consul: ", err.Error())
    }
    // Get service from Consul
    serviceEntry, _, err := consulClient.Health().Service("my-service", "", false, nil)
    if err != nil {
        log.Fatal("Error getting service from Consul: ", err.Error())
    }
    // Get service address and port
    serviceAddress := serviceEntry[0].Service.Address
    servicePort := serviceEntry[0].Service.Port
    // Connect to service
    conn, err := grpc.Dial(serviceAddress+":"+strconv.Itoa(servicePort), grpc.WithInsecure())
    if err != nil {
        log.Fatalf("Error connecting to service %s:%d [%s]", serviceAddress, servicePort, err.Error())
    }
    // Create
