You can deploy the Trident operator and install Astra Trident using Helm. 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 24.02

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.

Deploy the Trident operator and install Astra Trident using Helm

Using the Trident Helm Chart you can deploy the Trident operator and install Trident in one step.

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

Before you begin

In addition to the deployment prerequisites you need Helm version 3.

Steps

  1. Add the Astra Trident Helm repository:

    helm repo add netapp-trident https://netapp.github.io/trident-helm-chart

  2. Use helm install and specify a name for your deployment and image registry location. 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. In the examples, 100.2402.0 is the version of Astra Trident you are installing.

    Images in one registry
    helm install <name> netapp-trident/trident-operator --version 100.2402.0 --set imageRegistry=<your-registry> --create-namespace --namespace <trident-namespace>
    Images in different registries

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

    helm install <name> netapp-trident/trident-operator --version 100.2402.0 --set imageRegistry=<your-registry>/sig-storage --set operatorImage=<your-registry>/netapp/trident-operator:24.02.0 --set tridentAutosupportImage=<your-registry>/netapp/trident-autosupport:24.02 --set tridentImage=<your-registry>/netapp/trident:24.02.0 --create-namespace --namespace <trident-namespace>
    Note If you already created a namespace for Trident, the --create-namespace parameter will not create an additional namespace.

You can use helm list to review installation details such as name, namespace, chart, status, app version, and revision number.

Pass configuration data during install

There are two ways to pass configuration data during the install:

Option Description

--values (or -f)

Specify a YAML file with overrides. This can be specified multiple times and the rightmost file will take precedence.

--set

Specify overrides on the command line.

For example, to change the default value of debug, run the following --set command where 100.2402.0 is the version of Astra Trident you are installing:

helm install <name> netapp-trident/trident-operator --version 100.2402.0  --create-namespace --namespace trident --set tridentDebug=true
