Problems solved by technology
[0003] At present, the corresponding domain name resolution service components are usually used in the container cloud platform to provide domain name resolution services. However, when the access traffic is too high, the domain name resolution service components often experience an overload of domain name resolution, which leads to a crash and fails to work normally. Work, so that the container group that sends the access request cannot normally obtain the IP address of the container group to be accessed, so that the access traffic cannot reach the container group to be accessed

The invention provides a domain name resolution method and system of a container cloud platform, a computer readable storage medium and electronic equipment. The method comprises the following steps: detecting that a source container group generates a domain name resolution demand; in response to the domain name of the target container group contained in a pre-written kernel domain name mapping table, the source container group accesses the kernel domain name mapping table by using an operating system kernel to obtain the IP address of the target container group; and in response to the domain name which does not contain the target container group in the kernel domain name mapping table, the source container group sends a domain name resolution request to the domain name resolution service component to obtain the IP address of the target container group. Therefore, for the domain name resolution requirement pointing to the target container group pre-stored in the kernel domain name mapping table, the IP address of the target container group can be obtained by accessing the kernel domain name mapping table by using the kernel of the operating system without initiating a domain name resolution request, so that the workload of a domain name resolution service component is reduced, and the efficiency of domain name resolution is improved. The use of hardware resources for domain name resolution is reduced, and the domain name resolution efficiency is effectively improved.
Description
technical field [0001] The present application relates to the field of cloud native technologies, and in particular, to a domain name resolution method, system, computer-readable storage medium and electronic device of a container cloud platform. Background technique [0002] In the container cloud platform, different container groups (Pods) access each other through IP addresses. Before accessing a container group, usually only the domain name of the container group to be accessed is known. Therefore, the domain name of the container group to be accessed needs to be resolved through the domain name resolution service, the IP address of the container group to be accessed is obtained, and then the IP address of the container group to be accessed needs to be parsed. The container group that sends access request packets. [0003] At present, the corresponding domain name resolution service components are usually used in the container cloud platform to provide domain name resol...
