[prometheus] How to set prometheus alert ExternalURL value

[charlottehu111]

Describe the bug a clear and concise description of what the bug is.

It is more like a consulting issue.

We are using your prometheus chart to deploy in our kubenetes. We are using externalUrl to set the link in our alert template:

"activityTitle": "[{{ $alert.Annotations.description }}]({{ $externalUrl }})",

We are using externalUrl from alert request jason body as blow:

{
    "version": "4",
    "groupKey": "{}:{alertname=\"test_by_ying\"}",
    "status": "firing",
    "receiver": "teams_proxy",
    "groupLabels": {
        "alertname": "test_by_ying"
    },
    "commonLabels": {
        "alertname": "test_by_ying",
        "monitor": "master",
        "severity": "error"
    },
    "commonAnnotations": {
        "summary": "Server High Memory usage"
    },
    "externalURL": "http://docker.for.mac.host.internal:9093",
    "alerts": [
        {
            "labels": {
                "alertname": "test",
                "instance": "10.80.40.11:9100",
                "job": "docker_nodes",
                "monitor": "master",
                "severity": "error"
            },
            "annotations": {
                "description": "Test.",
                "summary": "Test"
            },
            "startsAt": "2018-03-07T06:33:21.873077559-05:00",
            "endsAt": "0001-01-01T00:00:00Z"
        }
    ]
}

We want to configure externalURL in alert. It seems that we should configure value.yaml in this two line: https://github.com/prometheus-community/helm-charts/blob/main/charts/prometheus/values.yaml#L77 and https://github.com/prometheus-community/helm-charts/blob/main/charts/prometheus/values.yaml#L705 due to your configuration code in file 1 and file 2:

          {{- if .Values.server.baseURL }}
            - --web.external-url={{ .Values.alertmanager.baseURL }}
          {{- end }}

However, I deployed using this command:

helm upgrade --install prometheus prometheus-community/prometheus -f prometheus.values.yaml --namespace istio-system --set alertmanager.baseURL=https://grafana.api.eu12.print.services.sap/d/k7VPy7WGk/logs\?orgId\=1 --set server.baseURL=https://grafana.api.eu12.print.services.sap/d/k7VPy7WGk/logs\?orgId\=1

and the configuration is inserted in our deployed prometheus deployment and alertmanager deployment:

     containers:
        - name: prometheus-server-configmap-reload
          image: 'jimmidyson/configmap-reload:v0.5.0'
          args:
            - '--volume-dir=/etc/config'
            - '--webhook-url=http://127.0.0.1:9090/-/reload'
          resources: {}
          volumeMounts:
            - name: config-volume
              readOnly: true
              mountPath: /etc/config
          terminationMessagePath: /dev/termination-log
          terminationMessagePolicy: File
          imagePullPolicy: IfNotPresent
          securityContext: {}
        - name: prometheus-server
          image: 'quay.io/prometheus/prometheus:v2.36.2'
          args:
            - '--storage.tsdb.retention.time=15d'
            - '--config.file=/etc/config/prometheus.yml'
            - '--storage.tsdb.path=/data'
            - '--web.console.libraries=/etc/prometheus/console_libraries'
            - '--web.console.templates=/etc/prometheus/consoles'
            - '--web.enable-lifecycle'
            - >-
              --web.external-url=<custom web external url>

      containers:
        - name: prometheus-alertmanager
          image: 'quay.io/prometheus/alertmanager:v0.24.0'
          args:
            - '--config.file=/etc/config/alertmanager.yml'
            - '--storage.path=/data'
            - '--cluster.listen-address='
            - >-
              --web.external-url=<custom web external url>

The externalUrl value in prometheus alert is still http://localhost:9093/ as default configuration in this line . It is not my <custom web external url>.

I wonder is there anything else I need to configure? Thanks
