Method of creating container, electronic device and storage medium

An electronic device, comprising:

• one or more processors;
• and
• a memory configured to store one or more programs,
• wherein the one or more programs, when executed by the one or more processors, is or are configured to cause the one or more processors to at least:
• acquire an available rack list and an available network address list, wherein the available rack list comprises a plurality of available racks of different available zones, each available rack comprises at least one server node, and the available network address list comprises at least one available network address, and each of the at least one available network address refers to a network address that is configured to set a Pod but has not been used yet, and the Pod is a smallest deployable working unit that is created and managed in Kubernetes;
• locate a spare server node in the plurality of available racks in the available rack list, wherein the spare server node refers to a server node with a spare resource, and the spare resource refers to a resource used for setting at least one container;
• create, on the spare server node, a current Pod corresponding to one of the at least one available network address, and create a current container in the current Pod, wherein the current container has an application to which the current container belongs and a group to which the current container belongs, the application to which the current container belongs, refers to an independent functional module in an independent service module on a product line, and the group to which the current container belongs, refers to an independent module for solving problems of different scenarios in the application to which the current container belongs, and is configured to manage an environment variable and an external configuration required for a container operation, and wherein the application to which the current container belongs, comprises at least one group;
• update the available network address list;
• re-order the plurality of available racks in the available rack list according to resource occupation information of each of the plurality of available racks in the available rack list and a preset rack priority level rule, wherein the resource occupation information of each of the plurality of available racks comprises a number of containers belonging to a same application, a number of containers belonging to a same group, and a first vacant-seat value, the first vacant-seat value is a ratio of a total number of resources of each of the plurality of available racks to a number of resources used by all created containers;
• and
• create another container according to a new spare server node in the plurality of re-ordered available racks in the available rack list and the updated available network address list,
• wherein the one or more programs is or are further configured to cause the one or more processors to at least:
• re-order server nodes in the plurality of available racks in the available rack list according to resource occupation information of the server nodes in the plurality of available racks in the available rack list,
• wherein the one or more programs is or are further configured to cause the one or more processors to at least:
• determine the new spare server node in the plurality of available racks according to the plurality of re-ordered available racks in the available rack list and the re-ordered server nodes in the plurality of available racks;
• and
• balance distribution of the created containers across the different available zones, the plurality of available racks, and the server nodes to improve fault tolerance of container clusters.

A non-transitory computer-readable storage medium having executable instructions therein, wherein the instructions, when executed by a processor, are configured to cause the processor to at least:

• acquire an available rack list and an available network address list, wherein the available rack list comprises a plurality of available racks of different available zones, each available rack comprises at least one server node, and the available network address list comprises at least one available network address, and each of the at least one available network address refers to a network address that is configured to set a Pod but has not been used yet, and the Pod is a smallest deployable working unit that is created and managed in Kubernetes;
• locate a spare server node in the plurality of available racks in the available rack list, wherein the spare server node refers to a server node with a spare resource, and the spare resource refers to a resource used for setting at least one container;
• create, on the spare server node, a current Pod corresponding to one of the at least one available network address, and create a current container in the current Pod, wherein the current container has an application to which the current container belongs and a group to which the current container belongs, the application refers to an independent functional module in an independent service module on a product line, and the group refers to an independent module for solving problems of different scenarios in the application and is configured to manage an environment variable and an external configuration required for a container operation, and wherein the application comprises at least one group;
• update the available network address list;
• re-order the plurality of available racks in the available rack list according to resource occupation information of each of the plurality of available racks in the available rack list and a preset rack priority level rule, wherein the resource occupation information of each of the plurality of available racks comprises a number of containers belonging to a same application, a number of containers belonging to a same group, and a first vacant-seat value, the first vacant-seat value is a ratio of a total number of resources of each of the plurality of available racks to a number of resources used by all created containers;
• and
• create another container according to a new spare server node in the plurality of re-ordered available racks in the available rack list and the updated available network address list,
• wherein the instructions are further configured to cause the processor to at least:
• re-order server nodes in the plurality of available racks in the available rack list according to resource occupation information of the server nodes in the plurality of available racks in the available rack list,
• wherein the instructions are further configured to cause the processor to at least:
• determine the new spare server node in the plurality of available racks according to the plurality of re-ordered available racks in the available rack list and the re-ordered server nodes in the plurality of available racks;
• and
• balance distribution of the created containers across the different available zones, the plurality of available racks, and the server nodes to improve resource utilization and fault tolerance of container clusters.
