This document describes how to grant permissions to access remote storage for backup and restore. During the backup process, TiDB cluster data is backed up to the remote storage. During the restore process, the backup data is restored from the remote storage to the TiDB cluster.
Amazon Web Service (AWS) provides different methods to grant permissions for different types of Kubernetes clusters. This document describes the following three methods.
The AWS client can read
AWS_SECRET_ACCESS_KEY from the process environment variables to obtain the associated user or role permissions.
s3-secret secret by running the following command. Use the AWS account's AccessKey and SecretKey. The secret stores the credential used for accessing S3-compatible storage.
kubectl create secret generic s3-secret --from-literal=access_key=xxx --from-literal=secret_key=yyy --namespace=test1
Create an IAM role.
First, create an IAM User for your account.
Then, Give the required permission to the IAM role you have created. Refer to Adding and Removing IAM Identity Permissions for details.
BackupCR needs to access the Amazon S3 storage, the IAM role is granted the
Associate IAM with the TiKV Pod:
When you use BR to back up TiDB data, the TiKV Pod also needs to perform read and write operations on S3-compatible storage as the BR Pod does. Therefore, you need to add annotations to the TiKV Pod to associate it with the IAM role.
kubectl edit tc demo1 -n test1
spec.tikv.annotations, add this annotation to it:
iam.amazonaws.com/role: arn:aws:iam::123456789012:role/user, and exit the editor. After the TiKV Pod is restarted, check whether the Pod has the annotation.
arn:aws:iam::123456789012:role/useris the IAM role created in Step 1.
When you use this method to grant permissions, you can create the EKS cluster and deploy TiDB Operator and the TiDB cluster.
Enable the IAM role for the

gcs-secret secret which stores the credential used to access GCS. The
google-credentials.json file stores the service account key that you have downloaded from the GCP console. Refer to GCP documentation for details.
kubectl create secret generic gcs-secret --from-file=credentials=./google-credentials.json -n test1
