When saving secret information locally in a file named .env and registering it with Kubernetes:
Execute the following script in the development environment during deployment.
# Set kubeconfig
export KUBECONFIG=${HOME}/.kube/my-kube-config
# If a secret already exists, delete it (for the next registration)
kubectl -n mynamespace delete secret myapp-env
# Register the local ../.env as a secret
kubectl -n mynamespace create secret generic myapp-env --from-env-file=../.env
When using it
