By default, you install Kyma with Serverless that uses the internal Docker registry running on a cluster. This tutorial shows how to override this default setup with an external Docker registry from one of these cloud providers:

• Docker Hub
• Google Container Registry (GCR)
• Azure Container Registry (ACR)

CAUTION: Function images are not cached in the Docker Hub. The reason is that this registry is not compatible with the caching logic defined in Kaniko that Serverless uses for building images.

Prerequisites

Steps

Create required cloud resources

Override Serverless configuration

Prepare yaml file with overrides that match your Docker registry provider:

CAUTION: If you want to set an external Docker registry before you install Kyma, manually apply the Secret to the cluster before you run the installation script.

Apply configuration

Deploy Kyma with different configuration for Docker registry . Run:

kyma deploy --values-file docker-registry-overrides.yaml
