Orphan container management in containerized environments

An article, comprising:

• a non-transitory storage medium comprising machine-readable instructions executable by a processor to perform:
• scanning a database for a containerized environment to acquire information for a set of containers for applications, the information including at least namespace associations and metadata for individual containers of the set of containers;
• detecting one or more orphan containers within the set of containers for applications, the one or more orphan containers being associated with unknown owner information;
• applying defined rules to determine owner information for at least one of the one or more orphan containers based at least in part on the namespace associations and metadata for the at least one of the one or more orphan containers;
• storing the determined owner information for the at least one of the one or more orphan containers in a storage device;
• initiating a timer in response to detecting at least one remaining orphan container of the one or more orphan containers for which the owner information remains unknown in response to the applying of the defined rules to determine the owner information;
• notifying one or more associated teams or stakeholders in response to at least one of:
• the determining the owner information for the at least one of the one or more orphan containers, or
• the detecting the at least one remaining orphan container of the one or more orphan containers for which the owner information remains unknown in response to the applying of the defined rules to determine the owner information;
• in response to expiration of the timer, deleting the at least one remaining orphan container for which owner information remains unknown;
• and
• in response to receiving a user input from the one or more associated teams or stakeholders claiming ownership of the at least one remaining orphan container, stopping the timer and inhibiting deletion of the at least one remaining orphan container.

A system comprising:

• at least one database to store a directed graph information for set of containers for applications in a containerized environment, wherein for an individual container of the set of containers, the directed graph information represents relationships between the individual container, a namespace, and an owner of the individual container;
• an orphan container detector to detect one or more orphan containers within the set of containers for applications, the directed graph information for the one or more orphan containers including unknown owner information;
• a rules engine to:
• apply defined rules to determine owner information for at least one of the one or more orphan containers based at least in part on namespace associations and metadata associated with the directed graph information for the at least one of the one or more orphan containers,
• initiate a timer in response to detecting at least one remaining orphan container of the one or more orphan containers for which the owner information remains unknown in response to the applying of the defined rules to determine the owner information,
• notify one or more associated teams or stakeholders in response to at least one of:
• the determining the owner information for the at least one of the one or more orphan containers, or
• the detecting the at least one remaining orphan container of the one or more orphan containers for which the owner information remains unknown in response to the applying of the defined rules to determine the owner information,
• in response to expiration of the timer, delete the at least one remaining orphan container for which owner information remains unknown;
• in response to receiving a user input from the one or more associated teams or stakeholders claiming ownership of the at least one remaining orphan container, stop the timer and inhibit deletion of the at least one remaining orphan container;
• and
• a storage device to store the determined owner information for the at least one of the one or more orphan containers in a storage device.
