Starting and Stopping ESS Services

Stopping a component

To stop a component, such as Synapse, it is necessary to stop the operator :

kubectl scale deploy/element-operator-controller-manager -n operator-onprem --replicas 0

Once the operator is stopped, you can delete the Synapse resource to remove all Synapse workloads :

kubectl delete synapse/first-element-deployment -n element-onprem

To get a list of resources that you can remove, you can look at the following command :

kubectl get elementdeployment/first-element-deployment -n element-onprem  --template='{{range $key, $value := .status.dependentCRs}}{{$key}}{{"\n"}}{{end}}'

Starting a component

To stop a component, such as Synapse, it is necessary to start the operator :

kubectl scale deploy/element-operator-controller-manager -n operator-onprem --replicas 1

Because the Synapse resource will automatically have been recreated by the updater, the operator on startup will automatically detect it and recreate all synapse workloads.
