Create Guard to Allow Ingress with port
Create guard to allow ingress with a port is used to create a CloudekaGuard that will allow ingress traffic to pods with certain labels from pods with other labels that are in different namespaces, and only on certain ports. Using this syntax, you can control inbound access to your web application from permitted clients, and limit that access to only specified ports. You can first run the following syntax to create a YAML file with the name allow-ingress-with-port.
nano allow-ingress-with-port.yaml
Copy and paste the following YAML contents.
apiVersion: tenants.cloudeka.ai/v1alpha2
kind: CloudekaGuard
metadata:
name: allow-ingress-with-port
namespace: ns1
spec:
endpointSelector:
matchLabels:
app: web-app
ingress:
- fromEndpoints:
- matchLabels:
app: client-default
toPorts:
- ports:
- port: "8080"
protocol: TCP
After pasting the syntax, save the file by pressing Ctrl + O, then press the Enter key and exit the editor by pressing Ctrl + X. The next step is to apply Cloudeka Guard.
kubectl apply -f allow-ingress-with-port.yaml
