I've Prometheus operator which is working as expected https://github.com/coreos/prometheus-operator

Now I want to apply the alert manager from scratch

After reading the docs im came out with those yamls. but the problem is when I entered to the UI Nothing is shown, any idea what I miss here ?

http://localhost:9090/alerts I use port forwarding ...

This is all the config files I've apply to my k8s cluster I just want to do some simple test to see that it working and then extend it to our needs...

alertmanger_main.yml

---
apiVersion: monitoring.coreos.com/v1
kind: Alertmanager
metadata:
  name: main
  labels:
    alertmanager: main
spec:
  replicas: 3
  version: v0.14.0

alertmanger_service.yml

apiVersion: v1
kind: Service
metadata:
  name: alertmanager-main
spec:
  type: LoadBalancer
  ports:
  - name: web
    port: 9093
    protocol: TCP
    targetPort: web
  selector:
    alertmanager: main

testalert.yml 

kind: ConfigMap
apiVersion: v1
metadata:
  name: prometheus-example-rules
  labels:
    role: prometheus-rulefiles
    prometheus: prometheus
data:
  example.rules.yaml: |+
    groups:
    - name: ./example.rules
      rules:
      - alert: ExampleAlert
        expr: vector(1)

alertmanager.yml

global:
  resolve_timeout: 5m
route:
  group_by: ['job']
  group_wait: 30s
  group_interval: 5m
  repeat_interval: 12h
  receiver: 'webhook'
receivers:
- name: 'webhook'
  webhook_configs:
  - url: 'http://alertmanagerwh:30500/'

and to create secret I use

kubectl create secret generic alertmanager-main --from-file=alertmanager.yaml

what I need is some basic alerts in K8S and I follow the documatation but didnt find any good step by step tutorial

enter image description here

to check my sys for monitoring namespace

 ~  kubectl get pods -n monitoring                                                                                                                                                13.4m  Sun Feb 17 18:48:16 2019

I've also now changed the service to LoadBalancer and I try to enter like 

 ~  kubectl get svc -n  monitoring                                                                                                                                                507ms  Sun Feb 17 21:23:56 2019

alertmanager-main   LoadBalancer   100.22.170.666   38.482.152.331   9093:30904/TCP   23m

when I hit the browser with

38.482.152.331:9093 
38.482.152.331:30904

nothing happen...

当您考虑使用AlertManager时，除了常规配置和应用警报规则外，还AlertManager需要与Prometheus服务器集成。然后，Prometheus 实例可以跟踪任何传入的一系列事件，一旦检测到任何被识别的规则，它就会向嵌套的警报管理器触发警报。

为了启用警报，可能需要将以下配置附加到 Prometheus 实例：

alerting:
  alertmanagers:
  - static_configs:
    - targets:
      - 'alertmanagerIP:9093'

具体来说，AlertManager在CoreOS中的实现，可以按照官方Alerting文档中描述的步骤进行；但是，您可以在下面找到上述指南中保留的 Prometheus pod 警报配置示例：

apiVersion: monitoring.coreos.com/v1
kind: Prometheus
metadata:
  name: example
spec:
  replicas: 2
  alerting:
    alertmanagers:
    - namespace: default
      name: alertmanager-example
      port: web
  serviceMonitorSelector:
    matchLabels:
      team: frontend
  resources:
    requests:
      memory: 400Mi
  ruleSelector:
    matchLabels:
      role: prometheus-rulefiles
      prometheus: example
