The installation procedure for Trident is straightforward. You can choose between a generic install or a customized install, depending on your OpenShift cluster's network restrictions and access to external image repositories. If you're performing a generic installation, you can add the tridentctl binary to your path and install Trident by running the tridentctl install command, specifying a namespace for Trident's resources and CRDs.

You can verify that Trident is successfully installed by checking the pods that are running in the namespace or by using the tridentctl binary to check the installed version.

Creating Your File..

Creating your file is a straightforward process, but it does require some planning. Administrators can configure multiple storage backends based on project needs and storage system models.

This allows for advanced storage features like compression and specific disk types to be enabled.

Storage backends can also guarantee a certain level of performance with Quality of Service (QoS) levels.

Developers can then use these backends to create persistent volume claims (PVCs) and attach persistent storage to their containers on demand.

Trident has a rapid development cycle, releasing new versions four times a year, just like Kubernetes.

You can install Trident using a generic install or a customized install. For a generic install, you can simply add the tridentctl binary to your path and run the tridentctl install command, specifying a namespace for Trident. This will create CRDs, a Service, Deployment, and a DaemonSet that runs on all worker nodes.

Alternatively, you can manually install the Trident Operator by setting the location of the user cluster's kubeconfig file as an environment variable, then running the Helm command to install the Trident operator. This will create the Trident namespace and deploy the Trident operator.

To verify that Trident is successfully installed, you can check the pods that are running in the namespace or use the tridentctl binary to check the installed version. The tridentctl binary will display the server version and client version, which should match the version of Trident that you installed.

Here are the steps for a generic install:

1. Add the tridentctl binary to your path.

2. Run the tridentctl install command, specifying a namespace for Trident.

3. Trident will create CRDs, a Service, Deployment, and a DaemonSet that runs on all worker nodes.

Here's a summary of the Trident installation process:

You can also manually install the Trident Operator by running the following commands:

1. Set the location of the user cluster's kubeconfig file as an environment variable.

2. Run the Helm command to install the Trident operator.

3. Create the Trident namespace and deploy the Trident operator.

Remember to verify that Trident is successfully installed by checking the pods that are running in the namespace or using the tridentctl binary to check the installed version.

iSCSI and Storage

To enable the mapping of block storage volumes through the iSCSI protocol in Red Hat OpenShift, you must install the necessary packages by applying an MCO (Machine Config Operator) to your cluster after it is deployed.

The configuration process involves creating a MachineConfig YAML file, which can be done by copying and pasting the YAML code into the OCP web console and clicking Create. This YAML file specifies the necessary packages to support iSCSI functionality.

When not using multipathing, the YAML file contains a single entry for the iscsid service, which is enabled and started. This service is responsible for processing iSCSI requests.

When using multipathing, the YAML file contains entries for both the iscsid service and the multipathd service. The multipathd service is responsible for managing device-mapper multipath devices.

The process of applying the MachineConfig to the worker nodes takes approximately 20 to 30 minutes. You can verify whether the machine config is applied by using the oc get mcp command.

To confirm that the MachineConfig has been successfully applied and services have been started as expected, you can run the oc debug command with the appropriate flags.

Here are the services that are started when using multipathing:

StorageClass and PVCs

StorageClass and PVCs are the building blocks of persistent storage in Kubernetes.

A StorageClass is a way to map a backend to a storage system, and it's defined by a provisioner string that tells Trident which CSI driver to use.

Parameters can be specified as key-value pairs to narrow down the candidate list of backends.

Each backend has a storage.storageClasses attribute indicating the StorageClasses that can be used to provision a volume.

You can examine the list of backends that satisfy a StorageClass by running tridentctl get backend -o json.

A PVC definition can include annotations that enable users to pass feature arguments on a per-PVC basis.

In this example, the export policy and snapshot policy are explicitly set to reference pre-created policies.

Trident will take care of creating a volume and presenting it as a PV to the OpenShift cluster.

You can reference this PVC in your pod/deployment definitions just like any other.

Installation Steps

To install Trident on your OpenShift cluster, you'll need to follow these steps. First, set the location of your user cluster's kubeconfig file as an environment variable, so you don't have to reference it every time. This is done by running `export KUBECONFIG=~/ocp-install/auth/kubeconfig`.

Next, you can install Trident using Helm, which is a package manager for Kubernetes. To do this, you'll need to run the Helm command `helm install trident helm/trident-operator-22.01.0.tgz --create-namespace --namespace trident`. This will install the Trident operator and create a namespace for it.

Alternatively, you can manually install the Trident operator by creating the required resources, such as a ServiceAccount, ClusterRole, and ClusterRoleBinding. You can do this by running `oc create -f deploy/bundle.yaml`, which will create all the necessary resources for the Trident operator deployment.

Once you've installed the Trident operator, you can verify that it's successfully installed by checking the pods that are running in the namespace or by using the `tridentctl` binary to check the installed version. To do this, run `oc get pods -n trident` and `./tridentctl -n trident version`.

Here are the specific steps to manually install the Trident operator:

  1. Set the location of your user cluster's kubeconfig file as an environment variable.
  2. Create the TridentOrchestrator custom resource definition using the manifest `deploy/crds/trident.netapp.io_tridentorchestrators_crd_post1.16.yaml`.
  3. Create a namespace for Trident using the manifest `deploy/namespace.yaml`.
  4. Create the resources required for the Trident operator deployment, such as a ServiceAccount, ClusterRole, and ClusterRoleBinding, using the manifest `deploy/bundle.yaml`.
  5. Create a TridentOrchestrator using the manifest `deploy/crds/tridentorchestrator_cr.yaml`.

By following these steps, you should be able to successfully install Trident on your OpenShift cluster.
