To support Autotakeover, you must first:
Scheduled jobs are owned by the last cluster member who modified them. Jobs can also be controlled using Cluster Manager. If a cluster member goes down, all scheduled jobs on that cluster member must be moved to another cluster node. This process can be performed automatically using the heartbeat and Autotakeover features in Rundeck Enterprise version 2.1.0 and later releases.
Configure the heartbeat by adding the following settings in
# heartbeat interval in seconds rundeck.clusterMode.heartbeat.interval=30 # initial delay after startup to send heartbeat rundeck.clusterMode.heartbeat.delay=10 # remote execute/abort message processing interval in seconds rundeck.clusterMode.remoteExec.process.interval=10 # age in seconds since last heartbeat to consider another member inactive rundeck.clusterMode.heartbeat.considerInactive=150 # age in seconds since last heartbeat to consider another member dead rundeck.clusterMode.heartbeat.considerDead=300
Then configure Autotakeover by adding the following settings in
# enables autotakeover for members detected as "dead" rundeck.clusterMode.autotakeover.enabled=true # policy indicates which nodes to take over. "Any": all dead nodes. "Static": only allowed uuids rundeck.clusterMode.autotakeover.policy=any # delay in seconds to wait after sending autotakeover proposal rundeck.clusterMode.autotakeover.delay = 60 # sleep in minimum seconds between autotakeover atttempts for a particular destination rundeck.clusterMode.autotakeover.sleep = 300
If using static policy, you can configure a list of allowed member UUIDs to proceed with auto take-over if they are marked as dead. If a member is marked as dead and not in this list, auto take-over will not be performed. For example:
