Creating Internal Load Balancers in Public and Private Subnets

You can create Oracle Cloud Infrastructure load balancers to control access to services running on a cluster:

When you create a 'custom' cluster, you select an existing VCN that contains the network resources to be used by the new cluster. If you want to use load balancers to control traffic into the VCN, you select existing public or private subnets in that VCN to host the load balancers.

When you create a 'quick cluster', the VCN that's automatically created contains a public regional subnet to host a load balancer. If you want to host load balancers in private subnets, you can add private subnets to the VCN later.

Alternatively, you can create an internal load balancer service in a cluster to enable other programs running in the same VCN as the cluster to access services in the cluster. You can host internal load balancers in public subnets and private subnets.

To create an internal load balancer hosted on a public subnet, add the following annotation in the metadata section of the manifest file:

service.beta.kubernetes.io/oci-load-balancer-internal: 'true'

To create aninternal load balancerhosted on aprivate subnet, add both following annotations in the metadata section of the manifest file:

service.beta.kubernetes.io/oci-load-balancer-internal: 'true'

service.beta.kubernetes.io/oci-load-balancer-subnet1: 'ocid1.subnet.oc1..aaaaaa....vdfw'

whereocid1.subnet.oc1..aaaaaa....vdfwis the OCID of the private subnet.
