Configuration

The Metrics Agent chart is configured via values.yaml. This page describes the main options.

Top-level values

Key	Description	Default
nameOverride	Override deployment name prefix	alerthawk
replicas	Number of pod replicas	1

Image

Key	Description	Default
image.repository	Container image repository	thiagoguaru/alerthawk.metrics
image.tag	Image tag	3.1.12 (or chart appVersion)
image.pullPolicy	Pull policy	Always

Deployment strategy

Key	Description	Default
strategy.type	RollingUpdate or Recreate	RollingUpdate
strategy.rollingUpdate.maxSurge	Max surge	25%
strategy.rollingUpdate.maxUnavailable	Max unavailable	25%

Service account and RBAC

Key	Description	Default
serviceAccount.create	Create a ServiceAccount	true
serviceAccount.name	ServiceAccount name	alerthawk-sa
serviceAccount.annotations	Annotations	—
serviceAccount.clusterRoleBinding.create	Create ClusterRoleBinding	true
serviceAccount.clusterRoleBinding.clusterRole	ClusterRole to bind	cluster-admin

The agent needs cluster (or namespace) read access to collect metrics. By default the chart creates a ServiceAccount and binds it to cluster-admin. If you set serviceAccount.create: false, create the ServiceAccount and ClusterRoleBinding yourself.

Security context

Key	Description	Default
securityContext.allowPrivilegeEscalation	Allow privilege escalation	false
securityContext.privileged	Privileged container	false
securityContext.readOnlyRootFilesystem	Read-only root filesystem	false
securityContext.runAsNonRoot	Run as non-root user	false

  limits:
    cpu: 500m
    memory: 512Mi
  requests:
    cpu: 100m
    memory: 128Mi

Other

Key	Description	Default
progressDeadlineSeconds	Deployment progress deadline	600
revisionHistoryLimit	ReplicaSet history limit	10
terminationGracePeriodSeconds	Pod termination grace period	30
