replication-controller

replication-controller

The replication-controller is part of the Open Component Model Kubernetes controller set that enables transferring components from one OCM repository to another.

The behaviour of the replication-controller is similar to that of the ocm transfer command with the addition of a reconciliation loop. It can therefore be used to "subscribe" to components and ensure that any component versions matching a semantic version constraint will be replicated from the source OCM repository to the destination.

Installation

Install the latest version of the controller using the following command:

VERSION=$(curl -sL https://api.github.com/repos/open-component-model/replication-controller/releases/latest | jq -r '.name')

kubectl apply -f https://github.com/open-component-model/replication-controller/releases/download/$VERSION/install.yaml
