Installation

1. Requirement

• ikukantai Fleet is deployed, version >= 2.2
• Go is installed, version >= 1.22.4
• Docker is installed. docker command can be invoked without sudo
• upx is installed, version >= 4.2.4

2. Config katyusha as image of Activator

Let's assume that the nodes in your cluster are named node1, node2, node3. See spec.template.spec.affinity to fill this information into the activator-deployment.yaml file correctly.

Change Activator from deployed as DaemonSet to Deployment

$ kubectl -n knative-serving delete daemonset activator
$ kubectl apply -f config/activator-deployment.yaml

New raising Activator will deployed with image katyusha:dev

$ kubectl -n knative-serving get deploy activator -o yaml | grep image:
        image: docker.io/bonavadeur/katyusha:dev

3. Add configs to Configmap for Katyusha

katyusha uses these configs in ConfigMap config-ikukantai in namespace knative-serving:

Config	Description	Value	Example
ikukantai-enable-katyusha	enable/disable katyusha	bool	"true", "false"
katyusha-threads	number of processing threads in katyusha	integer	"10"
katyusha-enable-junbanmachi	enable/disable Layer-1 Queuing feature	bool	"true", "false"
katyusha-enable-fukabunsan	enable/disable Load Balancing feature	bool	"true", "false"
katyusha-enable-outoushuugou	enable/disable Response Pool feature	bool	"true", "false"
katyusha-junbanmachi-concurrent-request	number of concurrent request in Layer-1 Queue	integer	"10"

Example:
