reactjsHow can I set environment variables for a React.js application running in a Kubernetes cluster?
Environment variables can be set for a React.js application running in a Kubernetes cluster by either setting them as arguments when starting the container, or by setting them as ConfigMaps.
Setting them as arguments when starting the container:
kubectl run my-react-app --image=<image_name> --env="MY_VARIABLE_NAME=my_variable_value"
Setting them as ConfigMaps:
apiVersion: v1
kind: ConfigMap
metadata:
name: my-react-app-config
data:
MY_VARIABLE_NAME: my_variable_value
Then, you can mount the ConfigMap to the container using the --volume-mounts
argument when starting the container:
kubectl run my-react-app --image=<image_name> --volume-mounts="name=my-react-app-config,mountPath=/etc/config"
The environment variables will then be available to the React.js application.
