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
