# Security
|
|
|
|
VictoriaMetrics operator provides several security features, such as [PodSecurityPolicies](https://kubernetes.io/docs/concepts/policy/pod-security-policy/), [PodSecurityContext](https://kubernetes.io/docs/tasks/configure-pod-container/security-context/).
|
|
|
|
|
|
## PodSecurityPolicy.
|
|
|
|
By default, operator creates serviceAccount for each cluster resource and binds default `PodSecurityPolicy` to it.
|
|
|
|
Default psp:
|
|
```yaml
|
|
apiVersion: policy/v1beta1
|
|
kind: PodSecurityPolicy
|
|
metadata:
|
|
name: vmagent-example-vmagent
|
|
spec:
|
|
allowPrivilegeEscalation: false
|
|
fsGroup:
|
|
rule: RunAsAny
|
|
hostNetwork: true
|
|
requiredDropCapabilities:
|
|
- ALL
|
|
runAsUser:
|
|
rule: RunAsAny
|
|
seLinux:
|
|
rule: RunAsAny
|
|
supplementalGroups:
|
|
rule: RunAsAny
|
|
volumes:
|
|
- persistentVolumeClaim
|
|
- secret
|
|
- emptyDir
|
|
- configMap
|
|
- projected
|
|
- downwardAPI
|
|
- nfs
|
|
```
|
|
|
|
This behaviour may be disabled with env variable passed to operator:
|
|
```yaml
|
|
- name: VM_PSPAUTOCREATEENABLED
|
|
value: "false"
|
|
```
|
|
|
|
User may also override default pod security policy with setting: `spec.podSecurityPolicyName: "psp-name"`.
|
|
|
|
|
|
## PodSecurityContext
|
|
|
|
`PodSecurityContext` can be configured with spec setting. It may be useful for mounted volumes, with `VMSingle` for example:
|
|
|
|
```yaml
|
|
apiVersion: operator.victoriametrics.com/v1beta1
|
|
kind: VMSingle
|
|
metadata:
|
|
name: vmsingle-f
|
|
namespace: monitoring-system
|
|
spec:
|
|
retentionPeriod: "2"
|
|
removePvcAfterDelete: true
|
|
securityContext:
|
|
runAsUser: 1000
|
|
fsGroup: 1000
|
|
runAsGroup: 1000
|
|
extraArgs:
|
|
dedup.minScrapeInterval: 10s
|

|
