Restart controller

A method for restarting microservices in a controlled manner in a 5G network comprising a plurality of computing devices hosting a plurality of container clusters executing one or more network functions of the 5G network, the method comprising:

• receiving, by the 5G network, an indication of a deployment in the 5G network, the deployment defining a service to be implemented in the 5G network, the deployment including a desired number of instances of the microservice, wherein the desired number of microservice instances are instantiated in the 5G network;
• and
• in response to determining that restarts for the instances of the microservice are to be controlled and that a restart is requested:
• restarting the instances of the microservice in a controlled manner and in a sequence in accordance with restart criteria associated with the instances of the microservice to prevent downtime of the service during the restart.

A computer-readable storage medium having computer-executable instructions stored thereupon which, when executed by one or more processors of a computing device, cause the computing device to perform operations comprising:

• receiving, by a cloud computing environment, an indication of a deployment in the cloud computing environment, the deployment defining a service to be implemented in the cloud computing environment, the deployment including a desired number of instances of the service;
• determining a first state indicative of whether restarts for the instances of the service are to be controlled and a second state indicating that a restart for the instances of the service is requested;
• and
• in response to determining that restarts for the instances of the service are to be controlled and that a restart is requested:
• restarting the instances of the service in a controlled manner and in a sequence in accordance with restart criteria associated with the service to prevent downtime of the service during the restart.
