Question

Does a lodbalancer pass encrypted or unencrypted traffic?

When I put a DO loadbalancer in front of a k8s cluster, does the k8s reverse proxy receive HTTP or HTTPS requests? Or another way, does the loadbalancer unencrypt everything and just forward the equivalent HTTP request back to the proxy or service?

You can actually configure how you would like you DOKS Loadbalancer to behave through the use of service annotations!

All loadbalancers provisioned by kubernetes are managed by the Cloud Controller Manager(CCM) running on the master. Any manual modifications to the LB through the cloud panel will be overwritten by the CCM during its reconciliation process to ensure the LB is configured properly with the state defined by the kubernetes service.

In order to configure your LB you need to use kubernetes service annotations.

For information on how to apply annotations, you can use the command:

kubectl annotate --help

Docs for DO service annotations can be found here: https://www.digitalocean.com/docs/kubernetes/how-to/configure-load-balancers/

Service annotations can also be found on our public github repository:
