# Terraform provider for grafana mimir

This terraform provider allows you to interact with grafana mimir.

Currently only these components could be managed with the api:
- [alertmanager](https://grafana.com/docs/mimir/latest/references/architecture/components/alertmanager/)
- [ruler](https://grafana.com/docs/mimir/latest/references/architecture/components/ruler/)

See [Mimir API Reference](https://grafana.com/docs/mimir/latest/references/http-api/)

## Provider `mimir`

Example:

```
provider "mimir" {
ruler_uri = "http://localhost:8080/prometheus"
alertmanager_uri = "http://localhost:8080"
org_id = "mytenant"
}
```

### URI path

org_id = "mytenant"
username = "user"
password = "password"
}
```

#### Token

```
provider "mimir" {
ruler_uri = "http://localhost:8080/prometheus"
alertmanager_uri = "http://localhost:8080"
org_id = "mytenant"
token = "supersecrettoken"
}
```

### Headers

```
provider "mimir" {
ruler_uri = "http://localhost:8080/prometheus"
alertmanager_uri = "http://localhost:8080"
org_id = "mytenant"
header = {
"Custom-Auth" = "Custom value"
}
}
```

## Resource `mimir_rule_group_alerting`

```
resource "mimir_rule_group_alerting" "test" {
name = "test1"
namespace = "namespace1"
rule {
alert = "HighRequestLatency"
expr = "job:request_latency_seconds:mean5m{job=\"myjob\"} > 0.5"
for = "10m"
labels = {
severity = "warning"
}
annotations = {
summary = "High request latency"
}
}
}
```

## Resource `mimir_rule_group_recording`

```
resource "mimir_rule_group_recording" "record" {
name = "test1"
namespace = "namespace1"
interval = "6h"
query_offset = "5m"
rule {
expr = "sum by (job) (http_inprogress_requests)"
record = "job:http_inprogress_requests:sum"
}
}

```
resource "mimir_alertmanager_config" "test" {

route {
group_by = ["..."]
group_wait = "30s"
group_interval = "5m"
repeat_interval = "1h"
receiver = "pagerduty"
child_route {
group_by = ["..."]
group_wait = "30s"
group_interval = "5m"
repeat_interval = "1h"
receiver = "pagerduty"
}
}

receiver {
name = "pagerduty"
pagerduty_configs {
routing_key = "secret"

mimir_rule_group_alerting.alert1: Import prepared!
Prepared mimir_rule_group_alerting for import
mimir_rule_group_alerting.alert1: Refreshing state... [id=namespace1/alert1]

Import successful!
