The first embodiment is as follows:
referring to fig. 1, fig. 1 is a flowchart of an implementation of a virtual machine application management method in an embodiment of the present invention, where the method may include the following steps:
s101: and carrying out mirror image processing on the acquired kubernets software to generate a mirror image file.
One physical machine can be virtualized into a plurality of virtual machines through virtualization technology, the virtual machines share hardware resources of the physical machine, each virtual machine can be divided into different users for use, and management operations such as deletion, pause, recovery, start, stop and restart can be carried out on the virtual machines. And the management terminal can also perform operations of checking a system physical machine list, adding a physical machine, deleting the physical machine, inquiring the physical machine and the like on the physical machine resources. Each virtual machine can install an application program, such as tomcat, mysql and the like, and the virtual machine installation application program needs to be pre-installed with kubernets software.
When the kubernets software needs to be installed on the virtual machine to be installed, the kubernets software can be obtained, mirror image processing is carried out on the kubernets software, and a mirror image file is generated. The obtaining mode of the kubernets software is more generally to search the kubernets software from the installed virtual machines, and developers can pre-install the kubernets software in one or more virtual machines through an Application Programming Interface (API) to obtain the installed virtual machines. The mirror image file of the kubernets software is generated in a mirror image processing mode, the method is simple and easy to implement, and excessive human interference is not needed.
S102: and burning the image file into each virtual machine to be installed so as to enable each virtual machine to be installed to be provided with kubernets software.
After the image files of the kubernets software are generated in an image processing mode, the image files can be recorded into the virtual machines to be installed respectively, and therefore the kubernets software is installed on the virtual machines to be installed. And in order to ensure the smoothness of the kubernets software in operation, the installation directory of the kubernets software in the installed virtual machine can be obtained, and the mirror image files are recorded into the same installation directory in each virtual machine to be installed.
S103: and managing the application programs of the virtual machines by using kubernets software.
After each virtual machine to be installed is completely installed with the kubernets software, the management end can use the kubernets software to perform management operation on the application programs of each virtual machine, for example, the management end can select which virtual machine to run the corresponding application program, and perform operations such as online submission, editing, deleting, arranging and the like on the application programs. The management end may specifically implement the arrangement by using a container group Pod, a copy controller rc (replication controller), a Service, deployment of a deployment, and the like.
By applying the method provided by the embodiment of the invention, the kubernets software is searched in the installed virtual machines with the kubernets software installed, 1 image file is generated by carrying out image processing on the kubernets software, and the image file is recorded in each virtual machine to be installed, so that each virtual machine to be installed is provided with the kubernets software, and the kubernets software can be used for carrying out management operation on the application programs of each virtual machine.

In a specific embodiment of the present invention, the process of expanding each application program of each virtual machine may include the following steps:
the method comprises the following steps: packaging a pre-established application program by using an application container engine to obtain a container packaging application program;
step two: the container package application is distributed to the virtual machines.
For convenience of description, the above two steps may be combined for illustration.
When the application programs are installed on the virtual machines, corresponding application programs can be established for one or more virtual machines in advance through the web management interface, and the application programs established in advance are packaged by using the application container engine Docker to obtain container packaging application programs. By utilizing the container packaging application program, the advantages of portability, less occupied resources and rapid deployment between different platforms and cloud computing can be realized, and the container packaging application program is distributed to each virtual machine.
Specifically, a plurality of critical applications may be bound in a single container package application, or one container package application may include only one micro-service application (such as login, query, and the like), so that the micro-service application may be efficiently distributed in each virtual machine. And the scale of the container packaging application program can be expanded or contracted at any time, the container packaging application programs are organized into groups, load balance among the container packaging application programs can be provided, the container packaging application program is easy to upgrade into a new version, the elasticity of the container packaging application program is provided, and the container packaging application program is replaced if the container packaging application program fails.
In a specific embodiment of the present invention, the virtual process of each virtual machine includes:
and performing virtual machine expansion by using a KVM virtualization technology.
The process of virtualizing multiple virtual machines from one physical machine may utilize KVM virtualization technology for virtual machine extension. The KVM type virtual machine is a kernel-based virtual machine, which integrates a Linux kernel virtual machine monitor Hypervisor, the Hypervisor can enable an operating system which originally monopolizes physical machine resources to be installed in a plurality of virtual machines, so that a plurality of virtual machine operating systems can be simultaneously operated on one physical machine, the virtual machines share the hardware of the physical machine resources, and the Hypervisor is responsible for the allocation of various resources. The Linux-based memory management system is a very small module of the Linux, and can be used for doing a plurality of things such as task scheduling, memory management and hardware equipment interaction. The KVM type virtual machine is a unique management program, and by using the KVM virtual machine as a kernel module, the Linux kernel integrated management program can simplify management and improve performance by using the KVM virtual machine as a loadable module in a virtual environment. In this mode, each virtual machine is a conventional Linux process, and can be scheduled by a Linux scheduler.
Compared with other virtualization technologies, the KVM virtualization technology has many advantages, such as direct interaction with a kernel, active related development work in a Linux community, good performance, realization of technologies such as v2v and p2v and management of virtual machines, great competitiveness in the virtual machine industry as an open source tool, adoption of KVM as a default virtualization implementation technology in each large Linux release version, and wide applicability. Moreover, each virtual machine is obtained by adopting a KVM virtualization technology, so that the phenomena of different standards, lack of interoperability and the like among the virtual machines can be avoided, and the management operations of application, approval, recovery and the like of physical resources can be simplified.
