@Marvin How do I pass a kubernetes secret as an environment variable during deployment?

To pass a Kubernetes secret as an environment variable during deployment, you should use a Kubernetes Secret resource and reference it from your deployment manifest. The specific details on how to configure Kubernetes secrets within your Prefect deployment manifest are not fully excerpted in the documentation search results, but the general approach would be: 1. Create a Kubernetes Secret with the data you want to pass. 2. In your Kubernetes deployment YAML, under the

spec

for a container, use

env

or

envFrom

to reference the secret. For a more secure approach, here is a general example showing how you would reference a secret in a deployment manifest:

yaml
apiVersion: apps/v1
kind: Deployment
metadata:
  name: prefect-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      flow: your-flow-label
  template:
    metadata:
      labels:
        flow: your-flow-label
    spec:
      containers:
      - name: flow-container
        image: your-image:latest
        env:
        - name: ENV_VAR_NAME  # The name of the environment variable
          valueFrom:
            secretKeyRef:
              name: your-kubernetes-secret
              key: the-key-in-the-secret

Replace

your-kubernetes-secret

with the name of your Kubernetes Secret, and

the-key-in-the-secret

with the specific key within the secret where the data is stored. For detailed instruction on Prefect with Kubernetes, you can check the Prefect Docker deployment guide. It should be noted that while this guide mentions environment variables, it specifies that passing sensitive information like API keys as plain environment variables is not secure, so using Kubernetes Secrets is advised for sensitive data. If you seek further assistance on securely using Kubernetes secrets within the Prefect deployment context, you might need to check the Prefect documentation or community for updated practices or examples relevant to your use case.
