Exposing components #
CRD objects doesn’t have ingress
configuration.
Instead, you can use VMAuth as proxy between ingress-controller and VictoriaMetrics components.
It adds missing authorization and access control features and enforces it.
Access can be given with VMUser definition.
It supports basic auth and bearer token authentication:
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMAuth
metadata:
name: main-router
spec:
userNamespaceSelector: {}
userSelector: {}
ingress: {}
unauthorizedAccessConfig: []
Advanced configuration with cert-manager annotations:
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMAuth
metadata:
name: router-main
spec:
podMetadata:
labels:
component: vmauth
userSelector: {}
userNamespaceSelector: {}
replicaCount: 2
resources:
requests:
cpu: "250m"
memory: "350Mi"
limits:
cpu: "500m"
memory: "850Mi"
ingress:
tlsSecretName: vmauth-tls
annotations:
cert-manager.io/cluster-issuer: base
class_name: nginx
tlsHosts:
- vm-access.example.com
Simple static routing with read-only access to vmagent for username - user-1
with password Asafs124142
:
# curl vmauth:8427/metrics -u 'user-1:Asafs124142'
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMUser
metadata:
name: user-1
spec:
password: Asafs124142
targetRefs:
- static:
url: http://vmagent-base.default.svc:8429
paths: ["/targets/api/v1","/targets","/metrics"]
With bearer token access:
# curl vmauth:8427/metrics -H 'Authorization: Bearer Asafs124142'
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMUser
metadata:
name: user-2
spec:
bearerToken: Asafs124142
targetRefs:
- static:
url: http://vmagent-base.default.svc:8429
paths: ["/targets/api/v1","/targets","/metrics"]
It’s also possible to use service discovery for objects:
# curl vmauth:8427/metrics -H 'Authorization: Bearer Asafs124142'
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMUser
metadata:
name: user-3
spec:
bearerToken: Asafs124142
targetRefs:
- crd:
kind: VMAgent
name: base
namespace: default
paths: ["/targets/api/v1","/targets","/metrics"]
Cluster components supports auto path generation for single tenant view:
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMUser
metadata:
name: vmuser-tenant-1
spec:
bearerToken: some-token
targetRefs:
- crd:
kind: VMCluster/vminsert
name: test-persistent
namespace: default
target_path_suffix: "/insert/1"
- crd:
kind: VMCluster/vmselect
name: test-persistent
namespace: default
target_path_suffix: "/select/1"
- static:
url: http://vmselect-test-persistent.default.svc:8481/
paths:
- /internal/resetRollupResultCache
For each VMUser
operator generates corresponding secret with username/password or bearer token at the same namespace as VMUser
.
Basic auth for targets #
To authenticate a VMServiceScrape
s over a metrics endpoint use basicAuth
:
apiVersion: operator.victoriametrics.com/v1beta1
kind: VMServiceScrape
metadata:
labels:
k8s-apps: basic-auth-example
name: basic-auth-example
spec:
endpoints:
- basicAuth:
password:
name: basic-auth
key: password
username:
name: basic-auth
key: user
port: metrics
selector:
matchLabels:
app: myapp
---
apiVersion: v1
kind: Secret
metadata:
name: basic-auth
data:
password: dG9vcg== # toor
user: YWRtaW4= # admin
type: Opaque
Unauthorized access #
You can expose some routes without authorization with unauthorizedAccessConfig
.
Check more details in VMAuth docs -> Unauthorized access.

and VMUser
