Quick Installation Installation with managed etcd Installation with external etcd Quick kvstore set up is required which can be set up using an Installation with external etcd or using the Installation with managed etcd. Should you encounter any issues during the installation, please refer to the 75s probe-866bb6f696-tb926 1/1 Running 0 75s Installation with managed etcd The standard Quick Installation guide will set up Cilium to use Kubernetes CRDs to store and propagate
