Trust Manager Helm values

Trust Manager is an tool that manages trust bundles in Kubernetes and OpenShift clusters. Trust Manager is a small Kubernetes operator that helps reduce the overhead of managing TLS trust bundles in your clusters.

The following Trust Manager Helm values are supported by the Venafi Kubernetes Manifest tool.

CRDs

crds.enabled

Property crds.enabled
Type bool
Default
true

This option decides if the CRDs should be installed as part of the Helm installation.

crds.keep

Property crds.keep
Type bool
Default
true

This option makes it so that the "helm.sh/resource-policy": keep annotation is added to the CRD. This will prevent Helm from uninstalling the CRD when the Helm release is uninstalled.

Warning

When the CRDs are removed, all cert-manager custom resources (Certificates, Issuers, ...) will be removed too by the garbage collector.

Trust Manager

replicaCount

Property replicaCount
Type number,string,null
Default
1

The number of replicas of Trust Manager to run.

For example:
Use integer to set a fixed number of replicas

replicaCount: 2

Use null, if you want to omit the replicas field and use the Kubernetes default value.

replicaCount: null

Use a string if you want to insert a variable for post-processing of the rendered template.

replicaCount: ${REPLICAS_OVERRIDE:=3}

nameOverride

Note that enabling secret targets will grant Trust Manager read access to all secrets in the cluster.

secretTargets.authorizedSecretsAll

app.leaderElection.leaseDuration

Property app.leaderElection.leaseDuration
Type string

Default
10s

The interval between attempts by the acting leader to renew a leadership slot before it stops leading. This MUST be less than or equal to the lease duration.
