Configure an update center in an existing Team
For Teams you can execute the groovy code below under Manage Jenkins -> Script Console in Operations Center. You could also execute this groovy script through Operations Center CLI.
def team = Jenkins.instance.getItemByFullName('Teams/<TEAM_NAME>')
com.cloudbees.opscenter.plugins.updatecenter.ConnectedMasterUpdateCenterProperty prp = new com.cloudbees.opscenter.plugins.updatecenter.ConnectedMasterUpdateCenterProperty(new com.cloudbees.plugins.updatecenter.sources.LocalUpdateSource('<UPDATE_CENTER_NAME>'))
team.getProperties().replace(prp)
team.save()
Configure an update center in a Managed controller
For Managed controllers you can execute the groovy code below under Manage Jenkins -> Script Console in Operations Center. You could also execute this groovy script through Operations Center CLI.
