Referring to fig. 2, an embodiment of the present invention provides a method for creating a k8s cluster, where the method for creating a k8s cluster includes:
step S10, referring to fig. 5, creating a virtual cluster based on the virtual machine;
it should be noted that the execution subject of the present application is a terminal device, and the virtual machine is application software running on the terminal device.
The virtual machine technology used in the application is to virtualize a memory in an operating system of the terminal device, and because a memory space required by the actual operation of the creation of the k8s cluster is far larger than the size of the memory of the terminal device, in order to implement the creation of the k8s cluster on one terminal device, a user can virtualize a part of hard disks into the memory by using the memory virtualization technology, and divide the terminal device into a plurality of virtual terminal devices, so that one terminal device can simultaneously operate a plurality of operating systems, thereby implementing the creation and management of the k8s cluster on one terminal device, and reducing the overhead of additional terminal devices.
As shown in fig. 5, the virtual cluster created on the virtual machine is substantially the same as the control plane of the k8s cluster, except that the scheduler on the control plane of the k8s cluster is replaced with a synchronizer, wherein the synchronizer corresponds to a communication channel for connecting the host clusters of end devices. Wherein, the data storage is a data storage library.
The virtual cluster replaces the functions of resource creation and low-level resource automatic generation in a data storage library in a control plane of a k8s cluster, and can reduce the burden and the overhead of creating a k8s cluster by terminal equipment, because one virtual cluster can create one k8s cluster and one virtual machine can create a plurality of virtual clusters, thereby indirectly realizing the effect of creating and managing a plurality of k8s clusters on one terminal equipment.
Optionally, the step of creating a virtual cluster based on the virtual machine in step S10 includes:
step A, building a running environment which is the same as the host cluster based on the virtual machine, and replacing a scheduler in the running environment with a synchronizer to create a virtual cluster.
The host cluster, the control plane of the k8s cluster that actually exists in the operating system, can actually run in the terminal device.
The control plane of the k8s cluster can provide a channel for a user to create high-level resources in a data storage library and transmit low-level resources automatically generated based on the high-level resources to the host cluster, so that the end device can complete the creation of the k8s cluster.
And replacing the scheduler in the operating environment with a synchronizer in order to be able to transfer the low-level resources generated in the virtual cluster to the host cluster, wherein the synchronizer can be regarded as a communication channel, which is used for establishing a connection between the virtual cluster of the virtual machine and the host cluster of the terminal device, so that the low-level resources in the virtual cluster can be transferred to the host cluster, thereby playing a role of resource mapping.
Step S20, mapping the low-level resources in the first data storage library of the virtual cluster to the second data storage library of the host cluster through the synchronizer;
the first data repository refers to a data repository located in a virtual cluster for storing high-level resources created by users and low-level resources generated based on the high-level resources.
The second data repository is a data repository located in the host cluster, and is configured to store the received low-level resource, and start an api-server (Application Programming Interface-server), a second data repository, and a controller in the host cluster based on the low-level resource.
And step S30, monitoring the low-level resources based on the scheduler of the host cluster, and completing the creation of the k8S cluster.
The scheduler mainly has the function of enabling each node of the k8s cluster to be allocated with low-level resources by monitoring the low-level resources, enabling all the resources in the cluster to be used to the maximum, and further completing the creation of the k8s cluster, wherein the process of scheduling the low-level resources by the scheduler is divided into three parts, the first part is used for filtering cluster nodes which do not meet the cluster conditions, the second part is used for sorting the cluster nodes which meet the cluster conditions according to priority, and the third part is used for selecting the stage with the highest priority from the sorted cluster nodes.
The low-level resources are automatically generated based on the controller listening to the high-level resources, which are the basis for generating the k8s cluster.
The k8s cluster is a container cluster management system, can provide functions such as application deployment, maintenance, extension mechanism and the like, and can conveniently manage the cross-cluster operation of containerized applications.
Optionally, in step S30, the step of completing the creation of the k8S cluster based on the host cluster scheduler listening to the low-level resources includes:
step B1, based on the host cluster scheduler to monitor the low-level resource, completing the creation of container resource;
step B2, receiving the container resource, and completing the creation of k8s cluster based on the container resource.
The scheduler listens to the received low level resources for the purpose of container scheduling, i.e. container creation.
The container refers to a unit capable of running business services or applications, one or more containers can be run in a pod (place Old Documentation), and the pod is a basis for executing the container on the k8s cluster, so that the container, the pod and the k8s cluster have a symbiotic relationship.
The host cluster is also present in the terminal device, and is used for completing the creation of the k8s cluster, unlike the virtual cluster, which is present in a virtual machine, and is simulated by a user, and is virtual, and the code present between an operating system and the terminal device, and the host cluster is present in the operating system, and the role of the host cluster is really acting on the terminal device, so the host cluster in the application is equivalent to an agent for completing the creation of the k8s cluster. For example, the virtual cluster is a shopping website, the terminal device is a purchaser, the host cluster is equivalent to an agent for helping the purchaser to shop on the shopping website, and plays a role of helping the purchaser to shop, i.e., generating a container, and the container generated in the host cluster directly acts on the terminal device, so that the terminal device can create a plurality of k8s clusters without additional overhead.
In this embodiment, by building a virtual cluster on a virtual machine of a terminal device, the terminal device can expand a hard disk memory of the terminal device without depending on an additional terminal device, and thus, the cost required for creating a k8s cluster is reduced, by building a virtual cluster in the same operating environment on the virtual machine, the computing power, network performance and storage performance of the generated k8s cluster can be kept consistent with those of a k8s cluster generated by a large overhead in the prior art, and the effect of reducing the creation cost of the k8s cluster can still be achieved on the premise of not losing the computing power, network performance and storage performance of the k8s cluster, and by using a synchronizer to directly map low-level resources into a host cluster, that is, a situation that the cost is large when the terminal device generates low-level resources can be avoided, and a situation that resources are lost when the low-level resources are transmitted to the host cluster can be avoided, by doing the creation of the container on the host cluster, the overhead required to create the k8s cluster can still be reduced.
Further, referring to fig. 3, an embodiment of the present invention provides a method for creating a k8S cluster, where based on the embodiment shown in step S20, before the step of mapping low-level resources in a virtual cluster data storage library to a data storage library of a host cluster through a synchronizer, the method further includes:
step S21, referring to fig. 5, creating a high-level resource in the first data repository through the api-server component;
a user can provide various resource objects required by the k8s, such as pod, RC, Service and the like, based on the api-server component, the original high-level resources in the virtual cluster are empty, and after the creation of the resources such as pod, RC, Service and the like is detected, the high-level resources are deployed so as to have the functions of online deployment, copy setting, rolling upgrade, rollback and the like, so that the creation of the high-level resources in the first data storage library is realized, and the effect of reducing the creation overhead of the k8s cluster is achieved on the premise of not changing the original creation process of the k8s cluster.
Step S22, referring to fig. 5, the controller listens to the high-level resource to complete the automatic generation of the low-level resource in the first data storage library.
As shown in fig. 5, listening for the created deployment, i.e., high level resource, by the controller in the virtual cluster automatically generates a pod, i.e., low level resource.
In the prior art, the creation of high-level resources and the generation of low-level resources are both performed directly on a server of a terminal device, and because the memory size of the terminal device is far smaller than the memory size required for the actual operation of the creation of the k8s cluster, only one terminal device is far from being used to meet the creation of the k8s cluster, and the creation of the k8s cluster can be realized with the assistance of additional terminal devices, and such a creation scheme directly causes the creation overhead of the k8s cluster to be large, and a later-maintenance person can also face the problem of decentralized maintenance and management caused by the decentralized k8s cluster. In the application, by creating the high-level resources and generating the low-level resources on the virtual machine of the terminal device, because the virtual machine can set the memory size of the virtual hard disk, the memory size of the virtual machine required by the creation of the k8s cluster can be satisfied, and because the virtual machine exists on the terminal device, the resources created and generated on the virtual machine can be directly mapped onto the host cluster based on the synchronizer, so that the indirect creation of the container is realized, that is, the creation overhead of the k8s cluster is reduced, the problems of the loss of the computing power, the network performance and the storage performance of the k8s cluster caused by the reduction of the creation overhead of the cluster can be avoided, and the later-period maintenance personnel can intensively maintain and manage the k8s cluster.
Optionally, the listening, by the controller, of the high-level resource in step S22, and after the step of automatically generating the low-level resource in the first data storage library is completed, the method further includes:
and step C, deploying a pod for resolving the DNS domain name based on the generated low-level resource.
The function of the pod herein is added in the present application, because a Domain Name System (DNS) Domain Name for network access in a virtual cluster is not available, a pod running a special resolution DNS Domain Name needs to be deployed, so that the DNS Name of a low-level resource on the virtual cluster can be correctly resolved to a corresponding host cluster.
Wherein the DNS domain name corresponds to an address, and the correct DNS domain name can make the user more convenient to access and manage the k8s cluster.
In this embodiment, by creating high-level resources and generating low-level resources on the virtual cluster, the burden and overhead of the terminal device are reduced, the integrity of the creation process of the k8s cluster can be ensured, and by using the generated low-level resources, a pod for resolving a DNS domain name is deployed, thereby avoiding the situation that later-stage maintenance personnel cannot access and manage the k8s cluster quickly and conveniently due to incorrect DNS mapping to the host cluster.
Further, referring to fig. 4, an embodiment of the present invention provides a method for creating a k8S cluster, where based on the embodiment shown in step S30, after the step of listening to the low-level resource by the scheduler based on the host cluster and completing the creation of the k8S cluster, the method further includes:
and step S31, maintaining and managing the k8S cluster based on the virtual cluster.
After the k8s cluster is created, a user can maintain and manage the created k8s cluster through a virtual cluster on one terminal device, and maintenance of the k8s cluster corresponding to a later-period maintenance person is facilitated.
Optionally, after the step of maintaining and managing the k8S cluster based on the virtual cluster in step S31, the method further includes:
and step D, if the low-level resources in the first data storage library are detected to be changed, the synchronizer automatically maps the changed low-level resources into the second data storage library, and the updating of the k8s cluster is completed.
In order to complete the update of the k8s cluster and avoid the business service or system suspension caused by untimely update, the synchronizer still maps the changed low-level resources into the second data storage library, so that the scheduler in the host cluster can complete the update of the container resources, and then the update of the k8s cluster is completed.
In this embodiment, the k8s cluster is directly maintained and managed in the virtual cluster on the virtual machine, so that the operation of the user on the maintenance and management of the k8s cluster is simpler and faster, the problem that the maintenance and management of the k8s cluster are complex and difficult due to the independent characteristic of the created k8s cluster in the prior art is solved, the user can maintain and manage a plurality of k8s clusters only on one virtual machine of the terminal device, the inconvenience of distributed maintenance and management caused by a plurality of distributed k8s clusters is avoided, and the time and effort of the user on the maintenance and management of the k8s cluster in the later period are reduced.
In addition, an embodiment of the present invention further provides a device for creating a k8s cluster, where the device for creating a k8s cluster includes a memory, a processor, and a creating processing program of a k8s cluster that is stored in the memory and is executable on the processor, and the processor implements the steps of the method for creating a k8s cluster when executing the creating processing program of the k8s cluster.
