auto-ingress-operator

Description

为k8s集群里的service自动创建对应的ingress，可以指定service前缀，以及通过黑白名单来指定要生成的namespace

域名规则: <serviceName>---<namespace>.<autoIngressName>

Getting Started

You’ll need a Kubernetes cluster to run against. You can use KIND to get a local cluster for testing, or run against a remote cluster. Note: Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster kubectl cluster-info shows).

Running on the cluster

1.安装Operator

kubectl apply -f deploy/auto-ingress-operator.yaml

2.创建自己的域名规则

kubectl apply -f deploy/auto-ingress.yaml

annotations 中定义的标签可以认为是公共标签，最终将被继承到生成的 Ingress 中。因此可以通过 annotation 选择的 IngressController，并为该 Controller 配置一些公共标签。

配置文件如下

apiVersion: apps.ingress.com/v1
kind: AutoIngress
metadata:
  name: autoingress-sample
  annotations:
    kubernetes.io/ingress.class: nginx
spec:
  rootDomain: example.cn
  #servicePrefixes:
  #  - "srv"
  #  - "web"
  namespaces:
    - "infra--staging"
  namespaceblacklist:
    - "kube-system"
    - "ingress-nginx"
  tlsSecretName: "tls-test"

rootDomain: (必须), 后缀域名, 必须。
servicePrefixes: (可选), 指定适配以特定关键字开头的 service,不指定匹配所有。
namespaces: (可选), 只匹配特定namespace 下的service，不指定匹配所有namespace下svc。
namespaceblacklist: (可选), 适配特定namespace 下的service不生成ingress
tlsSecretName: （可选）指定使用的 https 证书在 k8s 集群中的名字。
