问题描述
因此,我已经使用Kubernetes在Google云上设置了我的应用程序.我有一个Pod,我想将其暴露在期望TCP请求的群集之外.
So I have setup my application on Google cloud using Kubernetes. I have a Pod which I want to expose out of the cluster that expects TCP requests.
我知道可以通过 ingress-nginx 并对此进行了研究.如在此处提供文档,可以通过设置如下的configMap来完成:
I came to know that this is possible via ingress-nginx and researched about it. As mentioned in the docs here, it can be done by setting up a configMap like below:
apiVersion: v1
kind: ConfigMap
metadata:
name: tcp-configmap-example
data:
9000: "default/my-service-name:7051
,但是它的完整用法没有明确描述,我也无法在文档中找到完整的示例.
, but it's full usage is not clearly described nor I could find a complete example in the docs properly.
我已经按照安装指南所述安装了ingress-nginx我不确定下一步要暴露我的Pod.
I have installed ingress-nginx as mentioned in the Installation Guide but I am unsure what the next steps are to expose my Pod.
其他信息
- 我要从群集中公开的Pod中的端口是
7051
- 我有一个针对我Pod端口的NodePort服务,该端口可与Ingress一起使用来公开.
推荐答案
因此,要实现此目的,您可以执行以下操作:
So, in order to achieve this you can do this:
- 首先创建您添加到帖子中的configMap.
apiVersion: v1
kind: ConfigMap
metadata:
name: tcp-configmap-example
data:
9000: "default/my-service-name:7051
-
然后通过将此标志添加到容器args中来编辑您的nginx-ingress-controller部署,如下所示:
Then edit your nginx-ingress-controller deployment by adding this flag to container args like below:
...
containers:
- name: nginx-ingress-controller
image: "quay.io/kubernetes-ingress-controller/nginx-ingress-controller:0.26.1"
imagePullPolicy: "IfNotPresent"
args:
- /nginx-ingress-controller
- --default-backend-service=nginx-ingress/nginx-ingress-default-backend
- --election-id=ingress-controller-leader
- --ingress-class=nginx
- --configmap=nginx-ingress/nginx-ingress-controller
- --tcp-services-configmap=default/tcp-configmap-example
...
通过向您的LoadBalancer添加端口来编辑LoadBalancer服务
Edit LoadBalancer service by adding port to your LoadBalancer
...
ports:
- name: http
port: 80
protocol: TCP
targetPort: http
- name: https
port: 443
protocol: TCP
targetPort: https
- name: some-service-port
port: 7051
protocol: TCP
