Overview
Add-on description
The Kubernetes-csi-tencentcloud COS-CSI plug-in allows you to use Tencent Cloud Object Storage (COS) in your TKE cluster.
Kubernetes objects deployed in a cluster
Kubernetes Object Name | Type | Default Resource Consumption | Namespaces |
csi-coslauncher | DaemonSet | - | kube-system |
csi-cosplugin | DaemonSet | - | kube-system |
csi-cos-tencentcloud-token | Secret | - | kube-system |
Use Cases
COS is a distributed storage service provided by Tencent Cloud to store massive files. You can store and view data at any time over a network. Tencent Cloud COS provides scalable, affordable, reliable, and secure data storage services for all users.
With the COS-CSI add-on, you can quickly use COS as COSFS in your cluster through standard native Kubernetes. For more information, see COSFS.
Limits
Supports clusters with Kubernetes version 1.10 and later.
For Kubernetes 1.12 clusters, the following kubelet configuration must be added:
--feature-gates=KubeletPluginsWatcher=false.For more information on the limits of COSFS, see COSFS.
To use COS in TKE, you must install this add-on in your cluster, which consumes some system resources.
COS-CSI Permission
Permission Description
The permission of this component is the minimal dependency required for the current feature to operate.
The related directory /var/lib/kubelet on the host machine needs to be mounted to the container to accomplish volume mount/unmount, hence the activation of the privileged-level container is required.
Permission Scenarios
Feature | Involved Object | Involved Operation Permission |
Supporting COS bucket mounting in lite mode | PersistentVolume | get/watch/list/update |
| pod | get/create/delete/update |
Storing related COS configuration in the lite mounting method | configmap | get/create/delete/update |
Permission Definition
kind: ClusterRoleapiVersion: rbac.authorization.k8s.io/v1metadata:name: csi-cos-tencentcloudrules:- apiGroups: [""]resources: ["events", "persistentvolumes"]verbs: ["get", "watch", "update", "list"]- apiGroups: [""]resources: ["pods", "configmaps"]verbs: ["get", "create", "delete", "update"]
Usage
Installing the COS add-on
1. Log in to the TKE console and select Cluster in the left sidebar.
2. On the "Cluster Management" page, click the ID of the target cluster to go to the cluster details page.
3. In the left sidebar, click Add-On Management to go to the "Add-On List" page.
4. On the "Add-On List" page, click Create. On the "Create an Add-On" page that appears, select COS.
5. Click Finish to create the add-on.
Yes
No
