Percussive maintenance.Collection of various tools to keep things ship-shape. Not particularly bright tools, but good for a first-pass.Neutron resource reaperneutron-reaper{info, delete} {ip, port}<grace-days>[--dbversionocata ]Reclaims idle floating IPs and cleans up stale ports.Conflicting Ironic/Neutron MACsconflict-macs{info, delete} (--ignore-from-ironic-config<path to ironic.conf> |--ignore-subnet<subnet UUID> )The Ironic subnet must be provided—directly via ID or determined from a config—otherwise the script would think that they are in conflict.Undead Instances clinging to nodesundead-instances{info, delete}Nova instances that have been put to rest but still cling to Ironic nodes, preventing the next generation from being…ensouled? Checks for the inconsistency and fixed it.Clean up after IPMI errorsironic-error-resetter{info, reset}Resets Ironic nodes in error state with a known, common error. Records those resets on the node metadata (extrafield) and refuses after a magic number of attempts.Update orphaned resource providersorphan-resource-providers{info, update}Detects and updates resource providers whose UUID has not been updated to match a recreated Nova compute node.Common options:--slack<json-options>- if provided, used to post notifications to Slack--osrc<rc-file>- alternate way to feed in the OS authentication varsSetup/ConfigGet codemkdir-p/root/scripts/hammerscd/root/scripts/hammersgitclonehttps://github.com/ChameleonCloud/hammers.gitCreate environmentvirtualenv/root/scripts/hammers/venv/root/scripts/hammers/venv/bin/pipinstall-r/root/scripts/hammers/hammers/requirements.txt/root/scripts/hammers/venv/bin/pipinstall-e/root/scripts/hammers/hammersSet up credentials for OpenStack and SlackThe below cronjob assumes the OS var file is at/root/adminrcand the Slack vars are in/root/scripts/slack.json.
