Maintenance Guide

To maintain Steward you can put the system in maintenance mode. In this mode running pipeline runs will be processed to the end. Newly created pipeline runs will stay untouched.

Steps

Put Steward in maintenance mode

To put the system in maintenance mode you need to create a config map in the system namespace with specific content. See the file 'maintenance_mode_on.yaml' in this directory as an example.

kubectl apply -n steward-system -f maintenance_mode_on.yaml

Wait until the already started pipeline runs are finished.

You can list all non-finished pipelines with the following command:

 kubectl get spr --all-namespaces | grep -v finished

The installation can start when there are no pipeline runs at all or all pipeline runs are in one of these states:

  • finished

For each pipeline run without state you can also see an event with reason 'MaintenanceMode':

kubectl get event -n  "$TENANT_NAMESPACE"
LAST SEEN   TYPE     REASON            OBJECT                 MESSAGE
12s         Normal   MaintenanceMode   pipelinerun/ok-n9lcl   Maintenance mode skip

Install the new version of Steward

See Installing Steward

Switch off maintenance mode

To switch off the maintenance mode you can either delete the created config map:

kubectl delete -n steward-system -f maintenance_mode_on.yaml

or set maintenanceMode: "false":

kubectl apply -n steward-system -f maintenance_mode_off.yaml
