Customize tridentctl deployment

Trident installer enables you to customize attributes. For example, if you have copied the Trident image to a private repository, you can specify the image name by using --trident-image. If you have copied the Trident image as well as the needed CSI sidecar images to a private repository, it might be preferable to specify the location of that repository by using the --image-registry switch, which takes the form <registry FQDN>[:port].

To have Astra Trident automatically configure worker nodes for you, use --enable-node-prep. For more details on how it works, see here.

Note Automatic worker node preparation is a beta feature meant to be used in non-production environments only.

If you are using a distribution of Kubernetes, where kubelet keeps its data on a path other than the usual /var/lib/kubelet, you can specify the alternate path by using --kubelet-dir.

If you need to customize the installation beyond what the installer’s arguments allow, you can also customize the deployment files. Using the --generate-custom-yaml parameter creates the following YAML files in the installer’s setup directory:

  • trident-clusterrolebinding.yaml

  • trident-deployment.yaml

  • trident-crds.yaml

  • trident-clusterrole.yaml

  • trident-daemonset.yaml

  • trident-service.yaml

  • trident-namespace.yaml

  • trident-serviceaccount.yaml

After you have generated these files, you can modify them according to your needs and then use --use-custom-yaml to install your custom deployment.

./tridentctl install -n trident --use-custom-yaml
