mod_http_oauth2: Add support for the "openid" scope
This "openid" scope is there to signal access to the userinfo endpoint,
which is needed for OIDC support.
We don't actually check this later because the userinfo endpoint only
returns info embedded in the token itself, but in the future we may want
to check this more carefully.

--- labels: - 'Stage-Alpha' summary: Alertmanager webhook receiver for pubsub --- # Introduction This module lets [Alertmanager](https://prometheus.io/docs/alerting/latest/alertmanager/) publish alerts to [pubsub][doc:pubsub] via [webhooks](https://prometheus.io/docs/alerting/latest/configuration/#webhook_config). # Setup The relevant pubsub nodes must be created and configured somehow. Because the request IP address is used to publish, the `publisher` affiliation should be given to the IP address Alertmanager sends webhooks from. # Configuration ## Prometheus A Prometheus `rule_files` might contain something along these lines: ``` yaml groups: - name: Stuff rules: - alert: Down expr: up == 0 for: 5m annotations: title: 'Stuff is down!' labels: severity: 'critical' ``` ## Alertmanager On the Alertmanager site the webhook configuration may look something like this: ``` yaml receivers: - name: pubsub webhook_configs: - url: http://pubsub.localhost:5280/pubsub_alertmanager ``` And then finally some Alertmanager routes would point at that receiver: ``` yaml route: receiver: pubsub ``` ## Prosody On the Prosody side, apart from creating and configuring the node(s) that will be used, configure your pubsub service like this: ``` lua Component "pubsub.example.com" "pubsub" modules_enabled = { "pubsub_alertmanager", } -- optional extra settings: alertmanager_body_template = [[ *ALARM!* {annotations.title?Alert} is {status} Since {startsAt}{endsAt& until {endsAt}} Labels: {labels% {idx}: {item}} Annotations: {annotations% {idx}: {item}} ]] alertmanager_node_template = "alerts/{alert.labels.severity}" ``` If no node template is given, either an optional part after "pubsub_alertmanager" in the HTTP path is used as node, or the string "alerts". Here, an alerts would be published to different nodes based on the 'severity' label, so e.g. `alerts/critical` in this example. ## All Options Available configuration options: `alertmanager_body_template` : Template for the textual representation of alerts. `alertmanager_node_template` : Template for the pubsub node name, defaults to `"{path?alerts}"`
