Method and system for resource exposure in kubernetes, and device and medium

A computer device, comprising:

• at least one processor;
• and
• a memory, storing a computer instruction executable on the at least one processor, wherein the computer instruction, when being executed by the at least one processor, causes the at least one processor to:
• receive a first request for applying for a service resource, and in response to receiving first request, judge whether a mapping relationship between a label corresponding to a type of the service resource and virtual IPs exists in a first configuration file of a keepalived service;
• receive a second request for establishing a mapping relationship, and in response to the second request, acquire new virtual IPs and establish, in the first configuration file, a mapping relationship between the new virtual IPs and the label;
• and
• bind the virtual IPs corresponding to the label in the first configuration file to a plurality of pods corresponding to the service resource, so as to expose the plurality of the pods to entities outside of a kubernetes cluster by the virtual IP, and the plurality of the pods are part of the kubernetes cluster;
• receive a third request indicating existence of the mapping relationship, and in response to the third request indicating existence of the mapping relationship, judge whether a request for disconnecting the mapping relationship is received;
• and
• in response to receiving the request for disconnecting the mapping relationship, delete the mapping relationship from the first configuration file, and unbind the plurality of the pods corresponding to the service resource with the virtual IPs correspondingly, such that the exposing the plurality of the pods outside the kubernetes cluster by means of a native method of the kubernetes cluster.

A non-transitory computer readable storage medium, storing a computer program, wherein when the computer program is executed by at least one processor, the computer program is configured to cause the at least one processor to:

• receive a first request for applying for a service resource, and in response to receiving the first request, judge whether a mapping relationship between a label corresponding to a type of the service resource and virtual IPs exists in a first configuration file of a keepalived service;
• receive a second request for establishing a mapping relationship, and in response to the second request, acquire new virtual IPs and establish, in the first configuration file, a mapping relationship between the new virtual IPs and the label;
• and
• bind the virtual IPs corresponding to the label in the first configuration file to a plurality of pods corresponding to the service resource, so as to expose the plurality of the pods to entities outside of a kubernetes cluster by the virtual IP, and the plurality of the pods are part of the kubernetes cluster;
• receive a third request indicating existence of the mapping relationship, and in response to the third request indicating existence of the mapping relationship, judge whether a request for disconnecting the mapping relationship is received;
• and
• in response to receiving the request for disconnecting the mapping relationship, delete the mapping relationship from the first configuration file, and unbind the plurality of the pods corresponding to the service resource with the virtual IPs correspondingly, such that the exposing the plurality of the pods outside the kubernetes cluster by means of a native method of the kubernetes cluster.
