# Additional Scrape Configuration
AdditionalScrapeConfigs is an additional way to add scrape targets in VMAgent CRD.
There are two options for adding targets into VMAgent: inline configuration into CRD or defining it as a Kubernetes Secret.
No validation happens during the creation of configuration. However, you must validate job specs, and it must follow job spec configuration.
Please check official Prometheus documentation as references.
[Prometheus documentation](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#scrape_config).
## Inline Additional Scrape Configuration in VMAgent CRD
You need to add scrape configuration directly to the vmagent spec.inlineScrapeConfig. It is raw text in YAML format.
See example below
```yaml
cat <<EOF | kubectl apply -f -
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMAgent
metadata:
name: example-vmagent
spec:
serviceScrapeSelector: {}
replicas: 1
serviceAccountName: vmagent
inlineScrapeConfig: |
- job_name: "prometheus"
static_configs:
- targets: ["localhost:9090"]
remoteWrite:
- url: "http://vmagent-example-vmsingle.default.svc:8429/api/v1/write"
EOF
```
**Note**: Do not use passwords and tokens with inlineScrapeConfig use Secret instead of
## Define Additional Scrape Configuration as a Kubernetes Secret
You need to define Kubernetes Secret with a key.
The key is `prometheus-additional.yaml` in the example below
```yaml
cat <<EOF | kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
name: additional-scrape-configs
stringData:
prometheus-additional.yaml: |
- job_name: "prometheus"
static_configs:
- targets: ["localhost:9090"]
EOF
```
After that, you need to specify the secret's name and key in VMAgent CRD in `additionalScrapeConfigs` section
```yaml
cat <<EOF | kubectl apply -f -
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMAgent
metadata:
name: example-vmagent
spec:
serviceScrapeSelector: {}
replicas: 1
serviceAccountName: vmagent
additionalScrapeConfigs:
name: additional-scrape-configs
key: prometheus-additional.yaml
remoteWrite:
- url: "http://vmagent-example-vmsingle.default.svc:8429/api/v1/write"
EOF
```
**Note**: You can specify only one Secret in the VMAgent CRD configuration so use it for all additional scrape configurations.
