When you make updates to Edge through the UI or management APIs (for example, adding an API product or Developer App), the runtime plane needs to be able to retrieve those changes. To receive management plane updates for API products, developers, developer apps, caches, and KVM entries, you must expose the MART service endpoint publicly.
mart: serviceType: LoadBalancer
By default, the MART endpoint uses port 443 with SSL
pre-configured using a self-signed certificate. If you want to
switch to your own properly CA-signed certificate, configure
sslCertPath in your
overrides.yaml. For details on this configuration, see
Configuring SSL and encryption keys for MART.
