问题描述
我有一个简单的入口网络,我想从该入口网络访问位于不同名称空间的服务.
I have a simple ingress network, I want to access services at different namespaces, from this ingress network.
我该怎么做?我的入口网络yaml文件:
How I can do this?My ingress network yaml file:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: ingress
spec:
rules:
- host: api.myhost.com
http:
paths:
- backend:
serviceName: bookapi-2
servicePort: 8080
path: /booking-service/
我已将ExternalNames服务类型设置为yaml文件:
I've set the ExternalNames service type to the yaml file:
apiVersion: v1
kind: Service
metadata:
name: bookapi-2
namespace: booking-namespace
spec:
type: ExternalName
externalName: bookapi-2
ports:
- name: app
protocol: TCP
port: 8080
targetPort: 8080
selector:
app: bookapi-2
tier: backend-2
推荐答案
您可以从官方 Kubernetes文档中找到有关外部名称服务的更多信息:
当您想从其他名称空间访问服务时,您的Yaml可以示例,如下所示:
When you want to access a service from a different namespace, your yaml could, for example, look like this:
kind: Service
apiVersion: v1
metadata:
name: test-service-1
namespace: namespace-a
spec:
type: ExternalName
externalName: test-service-2.namespace-b.svc.cluster.local
ports:
- port: 80
对于您的Ingress yaml文件,请重新检查并确保它与官方示例兼容,例如示例此示例,因为其中包含一些不一致之处:
As to your Ingress yaml file, please recheck it and make sure it is compliant with the official examples, for example this one as it contains some inconsistency:
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
name: my-ingress
spec:
rules:
- host: www.mysite.com
http:
paths:
- backend:
serviceName: website
servicePort: 80
- host: forums.mysite.com
http:
paths:
- path:
backend:
serviceName: forums
servicePort: 80
也请重新检查ExternalName yaml,因为它具有TargetPorts和选择器,而在服务,并确保:
Please also recheck ExternalName yaml as it has TargetPorts and selectors which are not used in this type of Service and make sure that:
如果您不会成功,请分享您遇到的问题.
In case you will not succeed, please share the kind of problem you have meet.
