Description
Technical Field
The invention relates to the technical field of containerized JavaEE application servers, in particular to a secondary-mirror-free method for releasing a containerized JavaEE application server.
Background
A container refers to the interface between a component and the underlying service details. Before a web component, enterprise-level Bean, etc. can execute, it must be assembled as a java ee module and deployed on a container. In JAVA EE, various different types of modules can be deployed either by individually packaging JAR or by integrating these modules to make an EAR package. The application containerization occupies less resources and is quick to deploy, each application is packaged into a container mirror image, the container has greater advantage due to the one-to-one relation between each application and the container, and the container mirror image can be created for the application by using the container at the stage of build or release, because each application does not need to be combined with other application stacks and does not depend on a production environment infrastructure, and a consistent environment can be provided from research and development to test and production. The container is lighter in weight and more transparent than a virtual machine, which is more convenient for monitoring and management, so that the container network application aspect is widely adopted and becomes a mainstream technology commonly used in the current distributed architecture.
The existing release method of the containerized JavaEE application server at least needs to adopt mirror image twice, for example, the method for the automatic application program containerization and mirror image backup release disclosed in the document with the application number of CN201811363546.8 comprises the following four steps: step 1, constructing a basic mirror image: constructing a basic mirror image based on a hardware platform and an operating system; step 2, constructing a basic construction mirror image: starting a container from the basic mirror image, classifying the container by corresponding programming languages, and respectively making the basic mirror image in an incremental mode; step 3, constructing application program containerization mirror images: constructing a mirror image starting container from a foundation, injecting an application program source code into a known directory in the container, installing compiling and runtime dependent items for the application program source code, compiling the application program source code in the container, installing a corresponding file into a specified path, and submitting a new container as an application program containerization mirror image; step 4, carrying out containerized mirror image test and backup release on the application program: and running the application program containerization mirror image, and executing test verification by using the application program test script.
Traditionally, each set of images stored in a library must have all the files associated with its tiers, which means that to update a Docker image on any host device, we need to download the complete image from the library. Once the number of container systems increases to hundreds, thousands or millions of huge containers, the size of the library increases with the increase of container systems, and the amount of data to be downloaded per update becomes larger and larger, which results in a large container.

the antivirus system selecting an assignment information speed from the client module to the antivirus system based on the text set for antivirus scanning, capacity of a communication channel, and reserved throughput; allocating a portion of the determined reserved throughput of the antivirus system for performing an antivirus scan of text being opened based on the selected information dispatch rate.
8. The release method of the twice-image-free containerized JavaEE application server of claim 1, wherein the cloud platform adopts multi-channel signals for synchronous release, comprising:
setting the signal attribute of each channel signal according to the signal capacity of the multi-channel signal; compressing each channel signal according to the signal attribute under the condition of meeting the preset signal transmission quantity to obtain a corresponding compression branch, and storing the compression branches in parallel and continuously in a corresponding storage array on the cloud platform;
and when the cloud platform is used for issuing applications, all compression branches in the storage array are called to be issued synchronously.
9. The secondary-image-free containerized JavaEE application server releasing method of any one of claims 1 to 8, wherein the cloud platform runs on a virtual cluster in a network, the virtual cluster comprises a plurality of virtual machine nodes, a dependency relationship exists between rules for constructing the virtual cluster by the virtual machine nodes, and the cloud platform adopts the following algorithm to calculate the time complexity of the dependency relationship:
in the above formula, the first and second carbon atoms are,
representing the temporal complexity of the dependency;
representing a complexity function;
representing the number of virtual machine nodes in the virtual cluster;
and
all represent a linear growth constant;
temporal complexity of dependency relationships
And when the set value is reached, carrying out curing treatment on the cloud platform.
10. The release method of the containerized JavaEE application server free of secondary mirroring according to claim 9, wherein the physical resources occupied by the virtual cluster include a CPU, a memory and a storage, and the cloud platform manages and feeds back the physical resources occupied by the virtual cluster, including:
calculating an average consumption rate of the physical resource by the following formula:
in the above formula, the first and second carbon atoms are,
represents the average of the consumption rates of a CPU, memory, or storage;
representing a physical resource, i.e., CPU, memory, or storage;
representing a corresponding physical resource consumption rate;
representing the corresponding physical resource weight value;
and if the average value of the consumption rates of the physical resources reaches a preset threshold value, the cloud platform sends out alarm information that the comprehensive load capacity occupies the physical resources and exceeds the limit, and prompts that the physical resources need to be expanded or the load capacity needs to be reduced.
