Critical information about Astra Trident 23.07

You must read the following critical information about Astra Trident.

Critical information about Astra Trident

  • Kubernetes 1.27 is now supported in Trident. Upgrade Trident prior to upgrading Kubernetes.

  • Astra Trident strictly enforces the use of multipathing configuration in SAN environments, with a recommended value of find_multipaths: no in multipath.conf file.

    Use of non-multipathing configuration or use of find_multipaths: yes or find_multipaths: smart value in multipath.conf file will result in mount failures. Trident has recommended the use of find_multipaths: no since the 21.07 release.

Install Astra Trident using tridentctl

Review the installation overview to ensure you've met installation prerequisites and selected the correct installation option for your environment.

Before you begin

Before you begin installation, log in to the Linux host and verify it is managing a working, supported Kubernetes cluster and that you have the necessary privileges.

Note With OpenShift, use oc instead of kubectl in all of the examples that follow, and log in as system:admin first by running oc login -u system:admin or oc login -u kube-admin.
Details

  1. Verify your Kubernetes version:

    kubectl version

  2. Verify cluster administrator privileges:

    kubectl auth can-i '*' '*' --all-namespaces

  3. Verify you can launch a pod that uses an image from Docker Hub and reach your storage system over the pod network:

    kubectl run -i --tty ping --image=busybox --restart=Never --rm -- \
  ping <management IP>

Step 1: Download the Trident installer package

The Astra Trident installer package creates a Trident pod, configures the CRD objects that are used to maintain its state, and initializes the CSI sidecars to perform actions such as provisioning and attaching volumes to the cluster hosts. Download and extract the latest version of the Trident installer from the Assets section on GitHub. Update <trident-installer-XX.XX.X.tar.gz> in the example with your selected Astra Trident version.

wget https://github.com/NetApp/trident/releases/download/v23.07.1/trident-installer-23.07.1.tar.gz
tar -xf trident-installer-23.07.1.tar.gz
cd trident-installer

Step 2: Install Astra Trident

Install Astra Trident in the desired namespace by executing the tridentctl install command. You can add additional arguments to specify image registry location.

Standard mode
./tridentctl install -n trident
Images in one registry
./tridentctl install -n trident --image-registry <your-registry> --autosupport-image <your-registry>/trident-autosupport:23.07 --trident-image <your-registry>/trident:23.07.1
Images in different registries

You must append sig-storage to the imageRegistry to use different registry locations.

./tridentctl install -n trident --image-registry <your-registry>/sig-storage --autosupport-image <your-registry>/netapp/trident-autosupport:23.07 --trident-image <your-registry>/netapp/trident:23.07.1

Your installation status should look something like this.

....
INFO Starting Trident installation.                namespace=trident
INFO Created service account.
INFO Created cluster role.
INFO Created cluster role binding.
INFO Added finalizers to custom resource definitions.
INFO Created Trident service.
INFO Created Trident secret.
INFO Created Trident deployment.
INFO Created Trident daemonset.
INFO Waiting for Trident pod to start.
INFO Trident pod started.                          namespace=trident pod=trident-controller-679648bd45-cv2mx
INFO Waiting for Trident REST interface.
INFO Trident REST interface is up.                 version=23.07.1
INFO Trident installation succeeded.
....

Verify the installation

You can verify your installation using pod creation status or tridentctl.

Using pod creation status

You can confirm if the Astra Trident installation completed by reviewing the status of the created pods:

kubectl get pods -n trident

NAME                                  READY   STATUS    RESTARTS   AGE
trident-controller-679648bd45-cv2mx   6/6     Running   0          5m29s
trident-node-linux-vgc8n              2/2     Running   0          5m29s
Note If the installer does not complete successfully or trident-controller-<generated id> (trident-csi-<generated id> in versions prior to 23.01) does not have a Running status, the platform was not installed. Use -d to turn on debug mode and troubleshoot the issue.

Using tridentctl

You can use tridentctl to check the version of Astra Trident installed.

./tridentctl -n trident version

+----------------+----------------+
| SERVER VERSION | CLIENT VERSION |
+----------------+----------------+
| 23.07.1        | 23.07.1        |
