Installation

Direktiv is using Helm charts for installation. For a basic installation there are only two dependencies. A PostgreSQL database and Knative. Optional dependencies are Linkerd as service mesh and monitoring and tracing tools, e.g. backends for Direktiv's Opentlemetry configuration. The following diagram shows a high-level architecture of Direktiv and the required and optional components.

Direktiv Overview

The following sections explain how to install each component in a local cluster:

For testing there is a "all-in-one" Docker image available. It contains all required components alrteday installed and can be used for testing or development. It has a container registry installed on port 31212 as well which can be used to push local images.
