Secure Your Services with Istio: A Step-by-Step Guide to Setting up Istio TLS Connections
Introduction
Istio TLS configuration is one of the essential features when we enable a Service Mesh. Istio Service Mesh provides so many features to define in a centralized, policy way how transport security, among other characteristics, is handled in the different workloads you have deployed on your Kubernetes cluster.
One of the main advantages of this approach is that you can have your application focus on the business logic they need to implement. These security aspects can be externalized and centralized without necessarily including an additional effort in each application you have deployed. This is especially relevant if you are following a polyglot approach (as you should) across your Kubernetes cluster workloads.
So, this time we’re going to have our applications just handling HTTP traffic for both internal and external, and depending on where we are reaching, we will force that connection to be TLS without the workload needed to be aware of it. So, let’s see how we can enable this Istio TLS configuration
