Service update management

A computer-implemented system, comprising a computer processor coupled to a computer-readable memory unit, the memory unit comprising instructions that when executed by the computer processor implements a method comprising:

• during a first update procedure for a first service in a computing system, utilizing a detector to request an application programming interface (API) server to provide states about the first service and a second service;
• in response to a detection that the first update procedure is failed, checking, by one or more processors, a state of the second service on which the first service depends in the computing system;
• creating, by the detector, a state object for tracking a status of services undergoing updates and storing information about the failed first update procedure for the first service and its corresponding dependent service;
• triggering, by a timer, periodically the detector to obtain a latest state for the corresponding dependent service dynamically by retrying the corresponding dependent service and updating a state of the corresponding dependent service in the state object based on a latest state;
• in response to the second service being in a first state which indicates that a second update procedure of the second service is waiting for the computing system to allocate resources,
• suspending the first update procedure;
• releasing resources allocated to the first update procedure by the computing system;
• allocating the released resources to the second update procedure of the second service;
• implementing the second update procedure based on the allocated released resources;
• monitoring whether the second update procedure of the second service is finished when the released resources are allocated;
• and
• continuing the first update procedure once the second update procedure of the second service is finished.

A computer program product, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by an electronic device to cause the electronic device to perform a method, the method comprises:

• during a first update procedure for a first service in a computing system, utilizing a detector to request an application programming interface (API) server to provide states about the first service and a second service;
• in response to a detection that the first update procedure is failed, checking, by one or more processors, a state of the second service on which the first service depends in the computing system;
• creating, by the detector, a state object for tracking a status of services undergoing updates and storing information about the failed first update procedure for the first service and its corresponding dependent service;
• triggering, by a timer, periodically the detector to obtain a latest state for the corresponding dependent service dynamically by retrying the corresponding dependent service and updating a state of the corresponding dependent service in the state object based on a latest state;
• in response to the second service being in a first state which indicates that a second update procedure of the second service is waiting for the computing system to allocate resources,
• suspending the first update procedure;
• releasing resources allocated to the first update procedure by the computing system;
• allocating the released resources to the second update procedure of the second service;
• implementing the second update procedure based on the allocated released resources;
• monitoring whether the second update procedure of the second service is finished when the released resources are allocated;
• and
• continuing the first update procedure once the second update procedure of the second service is finished.
