# Create Secret

When creating a virtual machine using Object Storage (S3) as the image source, sometimes you need to fill in a secret to get through S3's verification. The following will introduce how to create a secret that meets the requirements of the virtual machine.

1. Click __Container Management__ in the left navigation bar, then click __Clusters__ , enter the details of the cluster where the virtual machine is located, click __ConfigMaps & Secrets__ , select the __Secrets__ , and click __Create Secret__ .

2. Enter the creation page, fill in the secret name, select the namespace that is the same as the virtual machine, and note that you need to select the default type __Opaque__ . The secret data needs to follow the following principles

    - accessKeyId: Data represented in Base64 encoding
    - secretKey: Data represented in Base64 encoding
