mod_http_oauth2: Fix treatment of 'redirect_uri' parameter in code flow
It's optional and the one stored in the client registration should
really be used instead. RFC 6749 says an URI provided as parameter MUST
be validated against the stored one but does not say how.
Given that the client needs their secret to proceed, it seems fine to
leave this for later.

--- 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}"`
