Connecting Reactjs app to Express server and DocumentDB (AWS MongoDB) in Kubernetes
The answer is to use variables, obviously. :)
My configuration has the following:
module.exports = { serverURL: process.env.SERVER_HOST};and the environment variable and value are stored in a Kubernetes configmap:
kubectl create configmap backend-configmap --from-literal SERVER_HOST=$SERVER_HOST--namespace="backend" --dry-run -o yaml | kubectl apply -f -In short, configuration should use variables and variables should be added as configmaps in Kubernetes. The deployments (pods) reference these configmaps.
