# ilo4-metrics-exporter
Simple proxy, providing temperatures from HPE iLO 4 as Prometheus metrics. Tested on versions 2.70 and 2.75 on MicroServer Gen8 only.
It requires iLO account with read permissions.
## Deployment
Helm chart is available in the repository https://mdvorak.github.io/ilo4-metrics-exporter
To use it, add it first into repository list and then install it
```shell
helm repo add ilo4-metrics-exporter https://mdvorak.github.io/ilo4-metrics-exporter
helm repo update
helm install ilo4-metrics-exporter/ilo4-metrics-exporter
```
### Credentials
Important: In order to work, deployment needs secret of same name to be present, with `login.json` key, containing
following object:
```json
{
"method": "login",
"user_login": "myusername",
"password": "mypassword"
}
```
_Note: User needs to have (and should have) readonly access only._
Secret sample:
```yaml
apiVersion: v1
kind: Secret
metadata:
name: ilo4-metrics-exporter
namespace: ilo4-metrics-exporter
stringData:
login.json: |
{"method": "login", "user_login": "myusername", "password": "mypassword"}
```
It is up to you, how will you create the secret.
If you are using, for example, [SealedSecrets](https://github.com/bitnami-labs/sealed-secrets), object can be
inlined into chart values, under `extraObjects` key, like this:
```yaml
ilo:
url: "https://0.0.0.0"
# ...
extraObjects:
- apiVersion: bitnami.com/v1alpha1
kind: SealedSecret
metadata:
name: ilo4-metrics-exporter
namespace: ilo4-metrics-exporter
spec:
encryptedData:
login.json: abcd12343567752dsadasda...
```
_Note: You should never leak unencrypted secrets via helm install, have them in Git repository etc._
### Certificate
If iLo is using self-signed certificate (default), it needs to be added to exporter config (otherwise SSL error will be
thrown):
```yaml
ilo:
url: "https://0.0.0.0"
certificate: |
-----BEGIN CERTIFICATE-----
MIIC...
-----END CERTIFICATE-----
```
### Security
Exporter does not need any security privileges, therefore it is recommended to set these in the values during
deployment:
```yaml
podSecurityContext:
runAsNonRoot: true
runAsUser: 65534
runAsGroup: 65534
securityContext:
capabilities:
drop: [ ALL ]
readOnlyRootFilesystem: true
```
_Note: These are not default in order to allow deployment in all kinds of environments._
