Using proxy services for dependencies in distributed computing systems

1. A method comprising:

intercepting, by a first proxy service running on a first node of a distributed computing system, a first request for a first service running on the first node, the first service being a service initiated by a system and service manager that executes as an initial process on the first node during a boot phase of the first node;

in response to intercepting the first request, accessing, by the first proxy service, dependency information that identifies a dependency between the first service and a second service, the second service being a service initiated by a system and service manager that executes as an initial process on a second node during a boot phase of the second node;

determining, by the first proxy service based on the dependency information, that the first service is dependent on the second service on the second node of the distributed computing system;

responsive to determining that the first service is dependent on the second service, connecting, by the first proxy service, to a second proxy service running on the second node;

sending, by the first proxy service to the second proxy service, a request to initiate the second service on the second node.

2. The method of claim 1 , further comprising:

invoking, by the first proxy service via the second proxy service, the second service running on the second node;

receiving, by the first proxy service, a first response from the second service; and

transmitting, by the first proxy service to the first service, the first response received from the second service.

3. The method of claim 2 , further comprising:

responsive to receiving the first response, generating, by the first service, a second response to the first request for the first service.

4. The method of claim 2 , further comprising:

transmitting, by the first proxy service, to the second service, a second request for data associated with the second service.

5. The method of claim 4 , further comprising:

responsive to receiving the second request, generating, by the second service, the first response comprising the data associated with the second service.

6. The method of claim 1 , wherein the first proxy service runs as a background service.

7. A system comprising:

a memory; and

a processing device coupled to the memory, the processing device to perform operations comprising:

intercepting, by a first proxy service running on a first node of a distributed computing system, a first request for a first service running on the first node, the first service being a service initiated by a system and service manager that executes as an initial process on the first node during a boot phase of the first node;

in response to intercepting the first request, access, by the first proxy service, dependency information that identifies a dependency between the first service and a second service, the second service being a service initiated by a system and service manager that executes as an initial process on a second node during a boot phase of the second node;

determining, by the first proxy service based on the dependency information, that the first service is dependent on the second service on the second node of the distributed computing system;

responsive to determining that the first service is dependent on the second service, connecting, by the first proxy service, to a second proxy service running on the second node;

sending, by the first proxy service to the second proxy service, a irst request to initiate the second service on the second node.

8. The system of claim 7 , wherein the operations further comprise:

invoking, by the first proxy service via the second proxy service, the second service running on the second node;

receiving, by the first proxy service, a first response from the second service; and

transmitting, by the first proxy service to the first service, the first response received from the second service.

9. The system of claim 8 , wherein the operations further comprise:

responsive to receiving the first response, generating, by the first service, a second response to the first request for the first service.

10. The system of claim 8 , wherein the operations further comprise:

transmitting, by the first proxy service, to the second service, a second request for data associated with the second service.

11. The system of claim 10 , wherein the operations further comprise:

responsive to receiving the second request, generating, by the second service, the first response comprising the data associated with the second service.

12. The system of claim 7 , wherein the first proxy service runs as a background service.

13. A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

intercepting, by a first proxy service running on a first node of a distributed computing system, a first request for a first service running on the first node, the first service being a service initiated by a system and service manager that executes as an initial process on the first node during a boot phase of the first node;

in response to intercepting the first request, accessing, by the first proxy service, dependency information that identifies a dependency between the first service and a second service, the second service being a service initiated by a system and service manager that executes as an initial process on a second node during a boot phase of the second node;

determining, by the first proxy service based on the dependency information, that the first service is dependent on the second service on the second node of the distributed computing system;

responsive to determining that the first service is dependent on the second service, connecting, by the first proxy service, to a second proxy service running on the second node;

sending, by the first proxy service to the second proxy service, a request to initiate the second service on the second node.

14. The non-transitory computer-readable storage medium of claim 13 , wherein the operations further comprise:

invoking, by the first proxy service via the second proxy service, the second service running on the second node;

receiving, by the first proxy service, a first response from the second service; and

transmitting, by the first proxy service to the first service, the first response received from the second service.

15. The non-transitory computer-readable storage medium of claim 14 , wherein the operations further comprise:

responsive to receiving the first response, generating, by the first service, a second response to the first request for the first service.

16. The non-transitory computer-readable storage medium of claim 14 , wherein the operations further comprise:

transmitting, by the first proxy service, to the second service, a second request for data associated with the second service.

17. The non-transitory computer-readable storage medium of claim 16 , wherein the operations further comprise:

responsive to receiving the second request, generating, by the second service, the first response comprising the data associated with the second service.
