Automating best practices using OPA Gatekeeper
To avoid human errors, you can define the best practices and constraints in the form of policies that can then be enforced automatically whenever a resource is created, deleted, or updated in the cluster. Automated policy enforcement ensures consistency and adherence to best practices without compromising agility and deployment velocity. One such software is Open Policy Agent (OPA) Gatekeeper, which is an admission controller that enforces policies based on the custom resource definition (CRD), executed by OPA. OPA Gatekeeper enables the enforcement of guard rails; any istio configuration not within the guard rails is automatically rejected. It also allows cluster administrators to audit the resources in breach of best practices. Using the following steps, we will set up OPA Gatekeeper, followed by the configuration to enforce some of the best practices for istio. Let’s get started!
