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 scrape_configs documentation as references.

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

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

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

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.
