Dynamic auto-configuration of multi-tenant PaaS components

A method comprising:

• monitoring, by a first configuration agent associated with a first Platform-as-a-Service (“PaaS”) component type, for a notification identifying a configuration file change in at least one configuration file directory, at least one configuration file in the at least one configuration file directory containing configuration data for at least one instance of the first PaaS component of the PaaS component type;
• monitoring, by a second configuration agent associated with a second Platform-as-a-Service (“PaaS”) component type, for a notification identifying a configuration file change in the at least one configuration file directory, the at least one configuration file in the at least one configuration file directory containing configuration data for at least one instance of the second PaaS component of the PaaS component type;
• monitoring, by the first configuration agent a configuration of the at least one instance of the first PaaS component type to identify a lack of conformity with configuration data in the at least one configuration file directory;
• monitoring, by the second configuration agent a configuration of the at least one instance of the second PaaS component type to identify a lack of conformity with configuration data in the at least one configuration file directory;
• and
• automatically transmitting, by the first configuration agent and the second configuration agent an instruction to the at least one instance of the first PaaS component and the second PaaS component when one or more of a configuration file change or a lack of conformity is identified, the instruction comprising an instruction to install a configuration on the at least one instance of the first PaaS component and the second PaaS component based on the configuration data in the at least one configuration file directory.

A method comprising:

• installing a service instance using a first descriptor chart, the installing comprising:
• installing a plurality of microservices declared in the first descriptor chart that comprise the service instance, at least one of the microservices configured to request services from an instance of a Platform-as-a-Service (“PaaS”) component of a PaaS component type, and
• creating at least one resource instance based on the first descriptor chart, the resource instance having a type associated with a resource definition, the resource instance containing configuration data associated with the instance of the PaaS component;
• storing the at least one resource instance;
• receiving, by a configuration agent that operates resource instances of the type associated with the resource definition, a notification of the creation of the at least one resource instance, the notification further comprising the configuration data associated with the instance of the PaaS component;
• instructing, by the configuration agent, the instance of the PaaS component to install the configuration data;
• updating the service instance using a second descriptor chart, the updating comprising:
• updating at least one of the plurality of microservices declared in the second descriptor chart that comprise the service instance, the updated at least one of the plurality of microservices configured to request services from the instance of the PaaS component, and
• updating the at least one resource instance based on the second descriptor chart by updating configuration data in the resource instance associated with the instance of the PaaS component;
• receiving, by the configuration agent that operates resource instances of the type associated with the resource definition, a notification of the update to the at least one resource instance, the notification further comprising the updated configuration data associated with the instance of the PaaS component;
• and
• instructing, by the configuration agent, the instance of the PaaS component to install the updated configuration data.

A method comprising:

• monitoring, by a first configuration agent associated with a first resource definition type, for a notification identifying that a declaration in a resource instance of the first resource definition type has changed, the changed declaration being associated with at least one instance of a first Platform-as-a-Service (“PaaS”) component;
• monitoring, by a second configuration agent associated with a second resource definition type, for a notification identifying that a declaration in a resource instance of the second resource definition type has changed, the changed declaration being associated with at least one instance of a second Platform-as-a-Service (“PaaS”) component;
• monitoring, by the first configuration agent, a configuration of the at least one instance of the first PaaS component to identify a lack of conformity with the declaration in the resource instance of the first resource definition type;
• monitoring, by the second configuration agent, a configuration of the at least one instance of the second PaaS component to identify a lack of conformity with the declaration in the resource instance of the second resource definition type;
• and
• automatically transmitting, by the first configuration agent and the second configuration agent, an instruction to the at least one instance of the first PaaS component and the second PaaS component when one or more of a declaration change or a lack of conformity is identified, the instruction comprising an instruction to install a configuration on the at least one instance of the first PaaS component and the second PaaS component based on the declaration in the resource instance.
