Contributors netapp-aruldeepa

You can manually deploy the Trident operator to install Astra Trident. This process applies to installations where the container images required by Astra Trident are stored in a private registry. If you do not have a private image registry, use the process for standard deployment.

Critical information about Astra Trident 24.06

You must read the following critical information about Astra Trident.

Critical information about Astra Trident

  • Kubernetes 1.31 is now supported in Astra 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.

Manually deploy the Trident operator and install Trident

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

Before you begin

Log in to the Linux host and verify it is managing a working and 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 contains everything you need to deploy the Trident operator and install Astra Trident. Download and extract the latest version of the Trident installer from the Assets section on GitHub.

wget https://github.com/NetApp/trident/releases/download/v24.06.0/trident-installer-24.06.0.tar.gz
tar -xf trident-installer-24.06.0.tar.gz
cd trident-installer

Step 2: Create the TridentOrchestrator CRD

Create the TridentOrchestrator Custom Resource Definition (CRD). You will create a TridentOrchestrator Custom Resources later. Use the appropriate CRD YAML version in deploy/crds to create the TridentOrchestrator CRD:

kubectl create -f deploy/crds/<VERSION>.yaml

Step 3: Update the registry location in the operator

In /deploy/operator.yaml, update image: docker.io/netapp/trident-operator:24.06.0 to reflect the location of your image registry. Your Trident and CSI images can be located in one registry or different registries, but all CSI images must be located in the same registry. For example:

  • image: <your-registry>/trident-operator:24.06.0 if your images are all located in one registry.

  • image: <your-registry>/netapp/trident-operator:24.06.0 if your Trident image is located in a different registry from your CSI images.

Step 4: Deploy the Trident operator

The Astra Trident installer provides a bundle file that can be used to install the operator and create associated objects. The bundle file is an easy way to deploy the operator and install Astra Trident using a default configuration.

  • For clusters running Kubernetes 1.24, use bundle_pre_1_25.yaml.

  • For clusters running Kubernetes 1.25 or later, use bundle_post_1_25.yaml.

Before you begin

  • By default, the Trident installer deploys the operator in the trident namespace. If the trident namespace does not exist, create it using:

    kubectl apply -f deploy/namespace.yaml

  • To deploy the operator in a namespace other than the trident namespace, update serviceaccount.yaml, clusterrolebinding.yaml and operator.yaml and generate your bundle file using the kustomization.yaml.

    1. Create the kustomization.yaml using the following command where <bundle.yaml> is bundle_pre_1_25.yaml or bundle_post_1_25.yaml based on your Kubernetes version.

      cp deploy/kustomization_<bundle.yaml> deploy/kustomization.yaml

    2. Compile the bundle using using the following command where <bundle.yaml> is bundle_pre_1_25.yaml or bundle_post_1_25.yaml based on your Kubernetes version.

      kubectl kustomize deploy/ > deploy/<bundle.yaml>
Steps

  1. Create the resources and deploy the operator:

    kubectl create -f deploy/<bundle.yaml>

  2. Verify the operator, deployment, and replicasets were created.

    kubectl get all -n <operator-namespace>
Important There should only be one instance of the operator in a Kubernetes cluster. Do not create multiple deployments of the Trident operator.

Step 5: Update the image registry location in the TridentOrchestrator

Your Trident and CSI images can be located in one registry or different registries, but all CSI images must be located in the same registry. Update deploy/crds/tridentorchestrator_cr.yaml to add the additional location specs based on your registry configuration.

Images in one registry
imageRegistry: "<your-registry>"
autosupportImage: "<your-registry>/trident-autosupport:24.06"
tridentImage: "<your-registry>/trident:24.06.0"
Images in different registries

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

imageRegistry: "<your-registry>/sig-storage"
autosupportImage: "<your-registry>/netapp/trident-autosupport:24.06"
tridentImage: "<your-registry>/netapp/trident:24.06.0"

Step 6: Create the TridentOrchestrator and install Trident

You can now create the TridentOrchestrator and install Astra Trident. Optionally, you can further customize your Trident installation using the attributes in the TridentOrchestrator spec. The following example shows an installation where Trident and CSI images are located in different registries.

kubectl create -f deploy/crds/tridentorchestrator_cr.yaml
tridentorchestrator.trident.netapp.io/trident created

kubectl describe torc trident

Verify the installation

There are several ways to verify your installation.

Using TridentOrchestrator status

The status of TridentOrchestrator indicates if the installation was successful and displays the version of Trident installed. During the installation, the status of TridentOrchestrator changes from Installing to Installed. If you observe the Failed status and the operator is unable to recover by itself, check the logs.

Status Description

Installing

The operator is installing Astra Trident using this TridentOrchestrator CR.

Installed

Astra Trident has successfully installed.

Uninstalling

The operator is uninstalling Astra Trident, because
spec.uninstall=true.

Uninstalled

Astra Trident is uninstalled.

Failed

The operator could not install, patch, update or uninstall
Astra Trident; the operator will automatically try to recover from this state. If this state persists you will require troubleshooting.

Updating

The operator is updating an existing installation.

Error

The TridentOrchestrator is not used. Another one already
exists.

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-7d466bf5c7-v4cpw        6/6     Running   0           1m
trident-node-linux-mr6zc                   2/2     Running   0           1m
trident-node-linux-xrp7w                   2/2     Running   0           1m
trident-node-linux-zh2jt                   2/2     Running   0           1m
trident-operator-766f7b8658-ldzsv          1/1     Running   0           3m

Using tridentctl

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

./tridentctl -n trident version
