The ingress can be configured in the following ways:

• Without SSL
• With SSL
• OAM URI’s are accessible from all hosts
• OAM URI’s are accessible using virtual hostnames only

The option you choose will depend on the architecture you are configuring. For example, if you have an architecture such as Oracle HTTP Server on an Independent Kubernetes cluster, where SSL is terminated at the load balancer, then you would configure the ingress without SSL.

In almost all circumstances, the ingress should be configured to be accessible from all hosts (using host.enabled: false in the values.yaml). You can only configure ingress to use virtual hostnames (using host.enabled: true in the values.yaml), if all of the following criteria are met:

• SSL is terminated at the load balancer
• The SSL port is 443
• You have separate hostnames for OAM administration URL’s (for example https://admin.example.com/em), and OAM runtime URL’s (for example https://runtime.example.com/oam/server).
