Swabbie

IMPORTANT: This service is currently under development, and is actively being used at Netflix for deleting images and snapshots of ebs volumes.

NOTE: If you're interested in contributing support for other providers or resource types, open an issue or join the Spinnaker Team slack and post in #swabbie.

Swabbie automates the cleanup of unused resources such as EBS Volumes and Images. As a Janitor Monkey replacement, it can also be extended to clean up a variety of resource types. Swabbie applies a set of rules to mark cleanup candidates. Once marked, a resource is scheduled for deletion, and an owner is notified. Before being deleted the resource is checked again to make sure it still qualifies for deletion. If so, it is deleted.

Deep Dive

Configuration

There are lots of configuration options. Configuration can be applied at the top level, at the provider level, or a the resource type level.

Top Level Config

Top level config is located under the swabbie key. Examples of top level properties are:

• dryRun
• work.intervalMs
• queue.monitorIntervalMs
• schedule

These map to SwabbieProperties.

Provider Level Config

Provider level config options control specifics about the overall provider config. Some examples are:

• locations
• maxItemsProcessedPerCycle
• itemsProcessedBatchSize
• exclusions

You can configure exclusions for the whole provider in this sections. These exclusions add to exclusions defined for each resource type.

These map to CloudProviderConfiguration.

Resource Type Level Config

Resource type level config options are for behavior of the specific resource type. Some examples are:

• dryRun
• maxAge
• exclusions
• notification

Any exclusions defined here apply for only the specific resource type and add to any exclusions defined at the provider level.

These map to ResourceTypeConfiguration.
