Upgrade a Trident operator installation

Contributors netapp-aruldeepa

You can upgrade Astra Trident using the Trident operator either manually or using Helm. You can upgrade from a Trident operator installation to another Trident operator installation or upgrade from a tridentctl installation to a Trident operator version. Review Select an upgrade method before upgrading a Trident operator installation.

Upgrade a manual installation

You can upgrade from a cluster-scoped Trident operator installation to another cluster-scoped Trident operator installation. All Astra Trident versions 21.01 and above use a cluster-scoped operator.

Note To upgrade from Astra Trident that was installed using the namespace-scoped operator (versions 20.07 through 20.10), use the upgrade instructions for your installed version of Astra Trident.
About this task

Trident provides a bundle file you can use to install the operator and create associated objects for your Kubernetes version.

Before you begin

Ensure you are using a Kubernetes cluster running a supported Kubernetes version.

Steps

  1. Verify your Astra Trident version:

    ./tridentctl -n trident version

  2. Delete the Trident operator that was used to install the current Astra Trident instance. For example, if you are upgrading from 23.07, run the following command:

    kubectl delete -f 23.07.0/trident-installer/deploy/<bundle.yaml> -n trident

  3. If you customized your initial installation using TridentOrchestrator attributes, you can edit the TridentOrchestrator object to modify the installation parameters. This might include changes made to specify mirrored Trident and CSI image registries for offline mode, enable debug logs, or specify image pull secrets.

  4. Install Astra Trident using the correct bundle YAML file for your environment, where <bundle.yaml> is
    bundle_pre_1_25.yaml or bundle_post_1_25.yaml based on your Kubernetes version. For example, if you are installing Astra Trident 23.10, run the following command:

    kubectl create -f 23.10.0/trident-installer/deploy/<bundle.yaml> -n trident

Upgrade a Helm installation

You can upgrade an Astra Trident Helm installation.

Warning When upgrading a Kubernetes cluster from 1.24 to 1.25 or later that has Astra Trident installed, you must update values.yaml to set excludePodSecurityPolicy to true or add --set excludePodSecurityPolicy=true to the helm upgrade command before you can upgrade the cluster.
Steps

  1. If you installed Astra Trident using Helm, you can use helm upgrade trident netapp-trident/trident-operator --version 23.10.0 to upgrade in one step. If you did not add the Helm repo or cannot use it to upgrade:

    1. Download the latest Astra Trident release from the Assets section on GitHub.

    2. Use the helm upgrade command where trident-operator-23.10.0.tgz reflects the version that you want to upgrade to.

      helm upgrade <name> trident-operator-23.10.0.tgz
      Note If you set custom options during the initial installation (such as specifying private, mirrored registries for Trident and CSI images), append the helm upgrade command using --set to ensure those options are included in the upgrade command, otherwise the values will reset to default.

  2. Run helm list to verify that the chart and app version have both been upgraded. Run tridentctl logs to review any debug messages.

Upgrade from a tridentctl installation to Trident operator

You can upgrade to the latest release of the Trident operator from a tridentctl installation. The existing backends and PVCs will automatically be available.

Steps

  1. Download the latest Astra Trident release.

    # Download the release required [23.10.0]
mkdir 23.10.0
cd 23.10.0
wget https://github.com/NetApp/trident/releases/download/v23.10.0/trident-installer-23.10.0.tar.gz
tar -xf trident-installer-23.10.0.tar.gz
cd trident-installer

  2. Create the tridentorchestrator CRD from the manifest.

    kubectl create -f deploy/crds/trident.netapp.io_tridentorchestrators_crd_post1.16.yaml

  3. Deploy the cluster-scoped operator in the same namespace.

    kubectl create -f deploy/<bundle-name.yaml>

serviceaccount/trident-operator created
clusterrole.rbac.authorization.k8s.io/trident-operator created
clusterrolebinding.rbac.authorization.k8s.io/trident-operator created
deployment.apps/trident-operator created
podsecuritypolicy.policy/tridentoperatorpods created

#Examine the pods in the Trident namespace
NAME                                  READY   STATUS    RESTARTS   AGE
trident-controller-79df798bdc-m79dc   6/6     Running   0          150d

trident-operator-5574dbbc68-nthjv     1/1     Running   0          1m30s

  4. Create a TridentOrchestrator CR for installing Astra Trident.

    cat deploy/crds/tridentorchestrator_cr.yaml
apiVersion: trident.netapp.io/v1
kind: TridentOrchestrator
metadata:
  name: trident
spec:
  debug: true
  namespace: trident

kubectl create -f deploy/crds/tridentorchestrator_cr.yaml

#Examine the pods in the Trident namespace
NAME                                READY   STATUS    RESTARTS   AGE
trident-csi-79df798bdc-m79dc        6/6     Running   0          1m
trident-csi-xrst8                   2/2     Running   0          1m
trident-operator-5574dbbc68-nthjv   1/1     Running   0          5m41s

  5. Confirm Trident was upgraded to the intended version.

    kubectl describe torc trident | grep Message -A 3
