Cloud Volumes

This section introduces how to attach cloud volumes to the component. For example, AWS ElasticBlockStore, Azure Disk, Alibaba Cloud OSS, etc.

Cloud volumes are not built-in capabilities in KubeVela so you need to enable these traits first. Let's use AWS EBS as example.

Install and check the TraitDefinition for AWS EBS volume trait.

kubectl apply -f https://raw.githubusercontent.com/oam-dev/kubevela/master/docs/examples/app-with-volumes/td-awsEBS.yaml
kubectl vela show aws-ebs-volume
+-----------+----------------------------------------------------------------+--------+----------+---------+
| NAME | DESCRIPTION | TYPE | REQUIRED | DEFAULT |
+-----------+----------------------------------------------------------------+--------+----------+---------+
| name | The name of volume. | string | true | |
| mountPath | | string | true | |
| volumeID | Unique id of the persistent disk resource. | string | true | |
| fsType | Filesystem type to mount. | string | true | ext4 |
| partition | Partition on the disk to mount. | int | false | |
| readOnly | ReadOnly here will force the ReadOnly setting in VolumeMounts. | bool | true | false |
+-----------+----------------------------------------------------------------+--------+----------+---------+

Then we can now attach a aws-ebs volume to a component.

apiVersion: core.oam.dev/v1beta1
kind: Application

name: app-worker
spec:
components:
- name: myworker
type: worker

- "1000"
traits:
- type: aws-ebs-volume
properties:
name: "my-ebs"
mountPath: "/myebs"
volumeID: "my-ebs-id"
