The docs states that
To create a Secret from one or more files, use --from-file. You specify files in any plaintext format, such as .txt or .env, as long as the files contain key-value pairs.

Is it even possible to do so from an .env file? kubectl get pods returns CreateContainerConfigError

To create a Kubernetes secret, apply one of the following methods: Use kubectl for a command-line based approach. Create a configuration file for the secret. Use a generator, such as Kustomize to generate the secret.
To use a Secret in an environment variable in a Pod: Create a Secret (or use an existing one). Multiple Pods can reference the same Secret. Modify your Pod definition in each container that you wish to consume the value of a secret key to add an environment variable for each secret key you wish to consume.
When using definition files, you can add the data in a base64 encoded format or plain text form. Kubernetes encodes the Secret data in base64 format. When you need to reveal a Secret text, you must base64-decode it. To enable containers to access Secrets, you have the option to mount the Secret as a volume.
Yes, use the option --from-env-file
kubectl create secret generic person --from-env-file=.test-secret To consume the secrets from the initial .env file in a pod, you can use the following :
apiVersion: v1 kind: Pod metadata: name: some-meta spec: containers: - name: xyz image: abc envFrom: - secretRef: name: person # <-- If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
