Installing Trust Manager using Helm¶

The Helm install comes with a publicly trusted certificate bundle package (for theuseDefaultCAs source) derived from Debian containers.

Step 1: Configure access to the Venafi OCI registry¶

Configure access to the Venafi OCI registry. Follow the instructions in Configuring access to the Venafi OCI Registry to enable access to the artifacts required for this component (cert-manager Components is the default scope for cert-manager). Use venafi as the namespace.

The sample file below, for example, assumes you created a Kubernetes Secret using venafi as the namespace and venafi-image-pull-secret as the name of the secret.

Step 2: Install cert-manager using Helm¶

If you are running Trust Manager in a production environment, it is highly recommended that you also install cert-manager, as it will handle the rotation of the certificates used by Trust Manager.

1. To install cert-manager in the venafi namespace, and configure it to use the pull-secret, create a file cert-manager.values.yaml containing the following content.

   US RegionEU RegionOwn Registry

   A sample cert-manager.values.yaml for users of the US region OCI registry:

   cert-manager.values.yaml

   global:
     imagePullSecrets:
       - name: venafi-image-pull-secret
   
   crds:
     enabled: true
   
   image:
     repository: private-registry.venafi.cloud/cert-manager/cert-manager-controller
   
   acmesolver:
     image:
       repository: private-registry.venafi.cloud/cert-manager/cert-manager-acmesolver
   
   webhook:
     image:
       repository: private-registry.venafi.cloud/cert-manager/cert-manager-webhook
   
   cainjector:
     image:
       repository: private-registry.venafi.cloud/cert-manager/cert-manager-cainjector
   
   startupapicheck:
     image:
       repository: private-registry.venafi.cloud/cert-manager/cert-manager-startupapicheck
   

   A sample cert-manager.values.yaml for users of the EU region OCI registry:

   cert-manager.values.yaml

   global:
     imagePullSecrets:
       - name: venafi-image-pull-secret
   
   crds:
     enabled: true
   
   image:
     repository: private-registry.venafi.eu/cert-manager/cert-manager-controller
   
   acmesolver:
     image:
       repository: private-registry.venafi.eu/cert-manager/cert-manager-acmesolver
   
   webhook:
     image:
       repository: private-registry.venafi.eu/cert-manager/cert-manager-webhook
   
   cainjector:
     image:
       repository: private-registry.venafi.eu/cert-manager/cert-manager-cainjector
   
   startupapicheck:
     image:
       repository: private-registry.venafi.eu/cert-manager/cert-manager-startupapicheck
   

   A sample cert-manager.values.yaml for users with their own OCI registry:

   cert-manager.values.yaml

   global:
     imagePullSecrets:
       - name: venafi-image-pull-secret
   
   crds:
     enabled: true
   
   image:
     repository: myregistry.example.com/cert-manager/cert-manager-controller
   
   acmesolver:
     image:
       repository: myregistry.example.com/cert-manager/cert-manager-acmesolver
   
   webhook:
     image:
       repository: myregistry.example.com/cert-manager/cert-manager-webhook
   
   cainjector:
     image:
       repository: myregistry.example.com/cert-manager/cert-manager-cainjector
   
   startupapicheck:
     image:
       repository: myregistry.example.com/cert-manager/cert-manager-startupapicheck
   

   Note

   As of cert-manager v1.15.0, the installCRDs value is deprecated in favor of crds.enabled.

2. Use Helm to install the software and wait for it to be ready:

   helm upgrade cert-manager oci://registry.venafi.cloud/charts/cert-manager \
     --install \
     --wait \
     --create-namespace \
     --namespace venafi \
     --values cert-manager.values.yaml \
     --version v1.16.2
   

   Note

   For more information about Helm support for OCI package distribution, see the Helm documentation.

Step 3: Install Trust Manager using Helm¶

1. Create a trust-manager.values.yaml file to define any Helm values you require. For example:

   app:
     trust:
       namespace: venafi
   image:
     repository: private-registry.venafi.cloud/trust-manager/trust-manager
   defaultPackageImage:
     repository: private-registry.venafi.cloud/trust-manager/cert-manager-package-debian
   imagePullSecrets:
   - name: venafi-image-pull-secret
   

   For more information on the available Helm values for Trust Manager, see Trust Manager Helm values.

2. Type the following command:

   helm upgrade trust-manager oci://registry.venafi.cloud/charts/trust-manager \
     --install \
     --wait \
     --namespace venafi \
     --values trust-manager.values.yaml \
     --version v0.14.0
   

   Note

   For more information about Helm support for OCI package distribution, see the Helm documentation.

   Installing Trust Manager without cert-manager

   If you want to install Trust Manager without also installing cert-manager, you can omit step 2 above and replace step 3.2 with the following:

   helm upgrade trust-manager oci://registry.venafi.cloud/charts/trust-manager \
     --install \
     --wait \
     --namespace venafi \
     --values trust-manager.values.yaml \
     --version v0.14.0 \
     --set app.webhook.tls.helmCert.enabled=true
   

   This functionality is only available in Trust Manager v.0.12.0 or later, and is not recommended for production environments.

How to uninstall Trust Manager using Helm¶

To uninstall Trust Manager installed via Helm, run the following command:

helm uninstall trust-manager --namespace venafi

These resources were kept due to the resource policy:
[CustomResourceDefinition] bundles.trust.cert-manager.io

release "trust-manager" uninstalled

As shown in the output, the CustomResourceDefinition for Bundle is not removed by the Helm uninstall command. This prevents data loss, as removing the CustomResourceDefinition would also remove all Bundle resources.

This command does not, by design, delete any CRDs. To do that you must also apply the following command:

kubectl delete crd bundles.trust.cert-manager.io

Secret targets¶

Secret targets are supported in Trust Manager v0.7.0 or later, but you must explicitly enable them on the controller. Enable this feature using the --set secretTargets.enabled=true Helm value. Because the controller needs RBAC to read and update secrets, you also need to set secretTargets.authorizedSecretsAll or secretTargets.authorizedSecrets.

Approver Policy / Approver Policy Enterprise integration¶

If you're running Approver Policy or Approver Policy Enterprise, the cert-manager's default approver will be disabled. This means that Trust Manager's webhook certificate will - by default - block when you install the Helm chart until it's manually approved.

As of Trust Manager v0.6.0, you can choose to automatically add an Approver Policy CertificateRequestPolicy that will approve the Trust Manager webhook certificate by adding the --set app.webhook.tls.approverPolicy.enabled=true flag to the Helm upgrade command if using Approver Policy or Approver Policy Enterprise.
