Cloud agnostic service discovery
A system may include a processing device and a memory storing instructions that, when executed by the processing device, causes the processing device to obtain a health check instruction that is specific to a name of a service that is associated with one or more endpoints, including performing a lookup with the name to obtain the health check instruction that is specific to the name. The processing device performs the one or more actions of the health check instruction to determine a health status of the one or more endpoints, and stores the health status of the one or more endpoints. In response to receiving a request to resolve the name from a client, the processing device returns the one or more endpoints based at least on the health status of the one or more endpoints.
1. A method, comprising:
obtaining a health check instruction that is specific to a name of a service that is associated with one or more endpoints of the service, wherein the obtaining comprises performing a lookup with the name to obtain the health check instruction that is specific to the name, and wherein the name encapsulates a set of criteria used for managing the one or more endpoints of the service;
performing, by a processing device, the one or more actions of the health check instruction to determine a health status of the one or more endpoints;
storing the health status of the one or more endpoints; and
in response to receiving a request to resolve the name from a client, returning the one or more endpoints based at least on the health status of the one or more endpoints.
2. The method of claim 1 , wherein returning the one or more endpoints based at least on the health status of the one or more endpoints comprises omitting those of the one or more endpoints that are unhealthy.
3. The method of claim 1 , wherein the health check instruction comprises performing a socket check of the one or more endpoints.
4. The method of claim 1 , wherein the health check instruction comprises querying a HyperText Transfer Protocol (HTTP) endpoint of the one or more endpoints.
5. The method of claim 1 , wherein performing the one or more actions of the health check instruction includes discovering the one or more endpoints associated with the service by querying a server with the name.
6. The method of claim 1 , wherein storing the health status of the one or more endpoints includes storing a timestamp with the health status, wherein the time stamp is associated with when the health check instruction was performed.
7. The method of claim 6 , wherein returning the one or more endpoints includes ignoring the health status of the one or more endpoints in response to the time stamp being older than a threshold amount.
8. A system comprising:
a memory; and
a processing device, operatively coupled to the memory, the processing device to:
obtain a health check instruction that is specific to a name of a service that is associated with one or more endpoints of the service, wherein to obtain the health check instruction comprises performing a lookup with the name to obtain the health check instruction that is specific to the name, and wherein the name encapsulates a set of criteria used for managing the one or more endpoints of the service;
perform the one or more actions of the health check instruction to determine a health status of the one or more endpoints;
store the health status of the one or more endpoints; and
in response to receiving a request to resolve the name from a client, return the one or more endpoints based at least on the health status of the one or more endpoints.
9. The system of claim 8 , wherein to return the one or more endpoints based at least on the health status of the one or more endpoints, the processing device is to omit those of the one or more endpoints that are unhealthy.
10. The system of claim 8 , wherein the health check instruction comprises to perform a socket check of the one or more endpoints.
11. The system of claim 8 , wherein the health check instruction comprises to query a HyperText Transfer Protocol (HTTP) endpoint of the one or more endpoints.
12. The system of claim 8 , wherein to perform the one or more actions of the health check instruction, the processing device is to discover the one or more endpoints associated with the service by querying a server with the name.
13. The system of claim 8 , wherein to store the health status of the one or more endpoints, the processing device is to store a timestamp with the health status, wherein the time stamp is associated with when the health check instruction was performed.
14. The system of claim 13 , wherein to return the one or more endpoints, the processing device is to ignore the health status of the one or more endpoints in response to the time stamp being older than a threshold amount.
15. A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a processing device, cause the processing device to:
obtain a health check instruction that is specific to a name of a service that is associated with one or more endpoints of the service, wherein to obtain the health check instruction comprises performing a lookup with the name to obtain the health check instruction that is specific to the name, and wherein the name encapsulates a set of criteria used for managing the one or more endpoints of the service;
perform the one or more actions of the health check instruction to determine a health status of the one or more endpoints;
store the health status of the one or more endpoints; and
in response to receiving a request to resolve the name from a client, return the one or more endpoints based at least on the health status of the one or more endpoints.
16. The non-transitory computer-readable storage medium of claim 15 , wherein to return the one or more endpoints based at least on the health status of the one or more endpoints, the processing device is to omit those of the one or more endpoints that are unhealthy.
17. The non-transitory computer-readable storage medium of claim 15 , wherein the health check instruction comprises to perform a socket check of the one or more endpoints.
18. The non-transitory computer-readable storage medium of claim 15 , wherein the health check instruction comprises to query a HyperText Transfer Protocol (HTTP) endpoint of the one or more endpoints.
19. The non-transitory computer-readable storage medium of claim 15 , wherein to perform the one or more actions of the health check instruction, the processing device is to discover the one or more endpoints associated with the service by querying a server with the name.
20. The non-transitory computer-readable storage medium of claim 15 , wherein to store the health status of the one or more endpoints, the processing device is to store a timestamp with the health status, wherein the time stamp is associated with when the health check instruction was performed.
