To use Kubernetes secrets in Cloud Engine infrastructure, you can follow these general steps:

1. Create a Kubernetes secret: You can create a Kubernetes secret using a YAML file that defines the secret. The YAML file should include the name of the secret, the type of secret, and the data that the secret contains.

For example, if you want to create a secret that contains a username and password, you can create a YAML file like this:

apiVersion: v1
kind: Secret
metadata:
  name: my-secret
type: Opaque
data:
  username: <base64-encoded-username>
  password: <base64-encoded-password>

Note that you need to base64 encode the username and password before adding them to the YAML file.

2. Deploy the secret: You can deploy the secret to your Kubernetes cluster using the kubectl apply command. Make sure that you are authenticated with the cluster before running this command.

kubectl apply -f my-secret.yaml

3. Use the secret in your application: You can use the secret in your application by referencing the secret in the deployment or pod YAML file. You can mount the secret as a volume or set environment variables with the data from the secret.

For example, if you want to mount the secret as a volume in your pod, you can add the following to your YAML file:

spec:
  containers:
  - name: my-container
    image: my-image
    volumeMounts:
    - name: my-secret-volume
      mountPath: /etc/my-secret
      readOnly: true
  volumes:
  - name: my-secret-volume
    secret:
      secretName: my-secret

This will mount the secret as a volume at /etc/my-secret in your container.

Note that you need to create a Kubernetes service account with the necessary permissions to access the secret before you can use it in your application.
