AlertManagerConfig: Add support for the new msteamsv2_configs receiver

AlertManagerConfig

What is missing? Please describe.

I'm running the prometheus-operator v0.72.0, but the latest has the same issue. I have manually set the version of alertmanager to v0.28.0-rc.0 in the "Alertmanager" object. I did this because alertmanager has added support for a new receiver: prometheus/alertmanager#4024 which is highly anticipated. But when I try to use it by adding it to my config (following the steps outlaid in prometheus/alertmanager#3920 (comment) ), it doesn't actually get synced into the alertmanager Pod.

It gets blocked by the prometheus operator which doesn't recognize the field:

level=error ts=2024-10-29T09:50:34.557049663Z caller=klog.go:126 component=k8s_client_runtime func=ErrorDepth msg="sync "prometheus-s ││ tack/prometheus-stack-prometheu-alertmanager" failed: provision alertmanager configuration: failed to initialize from secret: yaml: u ││ nmarshal errors:\n line 27: field msteamsv2_configs not found in type config.plain"

The problem is that prometheus-operator tries to marshal it, and it doesn't exist in the object here:

prometheus-operator/pkg/alertmanager/types.go

Line 99 in d2599cf

type receiver struct {

But it does here:
https://github.com/prometheus/alertmanager/blob/ff8c09d60174f27850830ceed6be38b3cf86974b/config/config.go#L988

Thanks in advance

We would need to wait till 0.28 is released 🙂

We would need to wait till 0.28 is released 🙂

Do you know if this is happening before end of December ?

Hello, we are having the same issue. Is there any workaround until the 0.28 gets released?
E.g adding the msteamsv2_configs via a configmap or secret to the receiver struct?

Hi there, just got updated alertmanager to 0.28.0 but issue still persists. I use prometheus stack chart version 68.3.0 with alertmanager v0.28.0 and prometheus operator v0.79.2 and can confirm issue exists. I can see reconciliation error like this
field msteamsv2_configs not found in type config.plain

However if I will exec into pod, change config directly and then reload alertmanager manually with kill -HUP 1 it will load and validate new conf.

Can someone validate it works on their side or it still an issue. Thanks)

I have the same issue with v68.3.0 kube prometheus stack chart. I also tried installing the alertmanager v0.28.0 chart by itself and encountered the same issue.
