Switching from swarm to kubernetes for a node while using the mixed orchestrator type

Question

I'm using the Mixed orchestrator type.How to switch from swarm to kubernetes for a node?

Answer 1

To change the orchestrator type for a node from Swarm to Kubernetes:

docker node update --label-add com.docker.ucp.orchestrator.kubernetes=true <node-id>
docker node update --label-rm com.docker.ucp.orchestrator.swarm <node-id>

UCP (Universal control panel) detects the node label change and updates the Kubernetes node accordingly.

Check the value of the orchestrator label by inspecting the node:

docker node inspect <node-id> | grep -i orchestrator

The docker node inspect command returns the node’s configuration, including the orchestrator:

"com.docker.ucp.orchestrator.kubernetes": "true"
