Go client for parsing Alertmanager config file?

[jthunder]

Hi guys,

I'd like to modify Alertmanager config programmatically - add/remove receivers - but didn't find any reliable libraries after googling in hours.

Does anyone know some useful libraries for this? 

Thanks

It's just YAML, so any library which parses and/or generates YAML should do.

In fact, some people just generate YAML with a plain text templating language (this is what Helm charts do).  It's a bit ugly and brittle, but if all you're doing is appending some receivers to an alertmanager config, it would work fine.

If you're worried that you may accidentally generate an invalid alertmanager config, you can run "amtool check-config" on your generated output to validate it.

The alertmanager's own structs are here: https://pkg.go.dev/github.com/prometheus/alertmanager/config but keep in mind that this isn't primarily intended as a library, so you may or may not be better off vendoring them.

Alertmanager structs can't really be used easily since for security
reasons they do not unmarshal secrets.
