There are a couple of driver options that can be passed as arguments when starting the driver container.
| Option argument | value sample | default | Description |
|---|---|---|---|
| endpoint | tcp://127.0.0.1:10000/ | unix:///var/lib/csi/sockets/pluginproxy/csi.sock | The socket on which the driver will listen for CSI RPCs |
| volume-attach-limit | 1,2,3 ... | -1 | Value for the maximum number of volumes attachable per node. If specified, the limit applies to all nodes. If not specified, the value is approximated from the instance type |
| extra-tags | key1=value1,key2=value2 | Tags attached to each dynamically provisioned resource | |
| k8s-tag-cluster-id | aws-cluster-id-1 | ID of the Kubernetes cluster used for tagging provisioned EBS volumes | |
| aws-sdk-debug-log | true | false | If set to true, the driver will enable the aws sdk debug log level |
| logging-format | json | text | Sets the log format. Permitted formats: text, json |
| user-agent-extra | csi-ebs | helm | Extra string appended to user agent |
| enable-otel-tracing | true | false | If set to true, the driver will enable opentelemetry tracing. Might need additional env variables to export the traces to the right collector |
| batching | true | true | If set to true, the driver will enable batching of API calls. This is especially helpful for improving performance in workloads that are sensitive to EC2 rate limits at the cost of a small increase to worst-case latency |
