Introduction So far, we have seen about two OPA use cases and their importance. Today, we’re going to look at a policy used to deny unauthorized configmap volumes from being mounted. What is a ConfigMap? Configmaps are similar to Kubernetes Secrets but are used to store non confidential configurations that Read more…
Introduction In this article, we’ll look into the OPA policy to deny host network. The reason is because setting the “hostNetwork: true” allows pods to access the network namespace of the host machine, on which the pod is running. For those who are wondering why a container accessing the host’s Read more…
Introduction In this blog post, we’ll see how and why we need to restrict wildcards in RBACs. How RBAC works? We’ll first look at the components that are needed for delegating access based on roles. Verbs – The verbs are the different actions that can be performed on a resource. Read more…
In this series of blog posts, we will be looking at deploying OPA gatekeeper as the admission controller for our Kubernetes cluster. We will be focusing specifically on creating gatekeeper policies for RBAC (Role Based access controls) in the Kubernetes cluster. If you want to know how the Audit logs Read more…
