Use your LoadBalancer with Supply Chain Security Tools - Store

This topic describes how to use your LoadBalancer with Supply Chain Security Tools (SCST) - Store.

Configure LoadBalancer

Note

LoadBalancer is not the recommended service type. Consider the recommended configuration of enabling Ingress.

To configure a LoadBalancer:

1. Edit /etc/hosts/ to use the external IP address of the metadata-store-app service.

   METADATA_STORE_IP=$(kubectl get service/metadata-store-app --namespace metadata-store -o jsonpath="{.status.loadBalancer.ingress[0].ip}")
   METADATA_STORE_PORT=$(kubectl get service/metadata-store-app --namespace metadata-store -o jsonpath="{.spec.ports[0].port}")
   METADATA_STORE_DOMAIN="metadata-store-app.metadata-store.svc.cluster.local"
   
   # Delete any previously added entry
   sudo sed -i '' "/$METADATA_STORE_DOMAIN/d" /etc/hosts
   
   echo "$METADATA_STORE_IP $METADATA_STORE_DOMAIN" | sudo tee -a /etc/hosts > /dev/null
   

   Note

   On EKS, you must get the IP address for the LoadBalancer. Find the IP address by running something similar to the following: dig RANDOM-SHA.us-east-2.elb.amazonaws.com. Where RANDOM-SHA is the EXTERNAL-IP received for the LoadBalancer.

2. Select one of the IP addresses returned from the dig command and write it to the /etc/hosts file.

Port forwarding

If you want to use port forwarding instead of the external IP address from the LoadBalancer, follow these steps:

Configure port forwarding for the service so the insight plug-in can access SCST - Store. Run:

kubectl port-forward service/metadata-store-app 8443:8443 -n metadata-store

Note: You must run the port forwarding command in a separate terminal window, or run the command in the background: kubectl port-forward service/metadata-store-app 8443:8443 -n metadata-store &

Edit your /etc/hosts file for Port Forwarding

Use the following script to add a new local entry to /etc/hosts:

METADATA_STORE_PORT=$(kubectl get service/metadata-store-app --namespace metadata-store -o jsonpath="{.spec.ports[0].port}")
METADATA_STORE_DOMAIN="metadata-store-app.metadata-store.svc.cluster.local"

# delete any previously added entry
sudo sed -i '' "/$METADATA_STORE_DOMAIN/d" /etc/hosts

echo "127.0.0.1 $METADATA_STORE_DOMAIN" | sudo tee -a /etc/hosts > /dev/null

Configure the Insight plug-in

Because you deployed Supply Chain Security Tools (SCST) - Store without using Ingress, you must use the Certificate resource app-tls-cert for HTTPS communication.

To get the CA Certificate:

kubectl get secret app-tls-cert -n metadata-store -o json | jq -r '.data."ca.crt"' | base64 -d > insight-ca.crt

Set the target by running:

tanzu insight config set-target https://$METADATA_STORE_DOMAIN:$METADATA_STORE_PORT --ca-cert insight-ca.crt

Important

The tanzu insight config set-target does not initiate a test connection. Use tanzu insight health to test connecting using the configured endpoint and CA certificate. Neither commands test whether the access token is correct. For that you must use the plug-in to add data and query data.
