Prerequisites

Import an application and its data onto PVCs

Additional options

When using custom docker registry

In cases where a custom Docker registry is employed, Stork needs to use such a registry while initiating the job which runs the rsync process. To customize the rsync image name, you can update the following environment variable in the StorageCluster specification:

stork:
  enabled: true
  env:
  - name: KDMP_RSYNC_IMAGE
    value: <custom-registry>/eeacms/rsync:<tag>

This allows you to specify a unique image location from your custom Docker registry.

When using Image Pull Secrets

The rsync operation runs inside the container eeacms/rsync. If you require the use of Image Pull Secrets to pull this image, you can provide the Kubernetes secret name as an environment variable. You should establish these image pull secrets within the same namespaces where Stork is deployed. You can manage this configuration as an environment variable in the StorageCluster specification, which you defined during Step 1 of the Import an application and its data onto PVCs section above.

stork:
  enabled: true
  env:
  - name: KDMP_RSYNC_IMAGE_SECRET
    value: <image-secret-name>

This allows for secure retrieval of the rsync image using the specified image pull secret.

Customizing the rsync flags

Customizing the rsync flags is possible, as the default configuration employs the following flags for the rsync command within the rsync job pod: -avz. To specify your own set of rsync flags, you can introduce an environment variable in the StorageCluster specification as follows:

stork:
  enabled: true
  env:
  - name: KDMP_RSYNC_FLAGS
    value: "-<custom-flags>"

Ensure to include a hyphen at the beginning of your custom flags within the specified value field. This enables you to fine-tune the rsync operation according to your specific requirements.

Supported environment variables

You should provide all the following environment variables within the env section for Stork in the StorageCluster specification:

Environment variable	Description
