Mirror Image (Image): the Docker image is a special file system that contains configuration parameters (e.g., environment variables) prepared for the container runtime in addition to the files of programs, libraries, resources, configuration, etc. required by the container runtime.
Kubernetes (K8S): kubernetes is a powerful container scheduling management platform and one of the best micro-service operating environments at present, and gives more value to Docker: the system can be scheduled, arranged, managed and expanded; the resource utilization rate of the cluster can be greatly improved through the Kubernetes management container and the bottom layer resources; the blockchain service deployed on the cloud in the alliance chain scene can be operated in a container mode by using Kubernets, and convenient management is achieved.

Based on the overall architecture of the intelligent contract management system in the blockchain in the prior art in fig. 2, fig. 3 schematically illustrates the overall process of the intelligent contract management method in the blockchain in the prior art, where the overall process includes operations S301 to S306, which are as follows:
in operation 301, receiving an intelligent contract deployment or execution request sent by a client;
in operation 302, the intelligent contract support module (i.e. chaincodessurt module) processes the request according to the type of the request, checks whether an intelligent contract communication handle exists in the handle management module (i.e. HandlerManager module), and if the intelligent contract communication handle does not exist in the handle management module, the intelligent contract operation support module (i.e. Runtime module) is entered to create an intelligent contract and update the communication handle;
in operation 303, a Launcher module in the intelligent contract running support module (i.e., runtime module) checks the running state of the intelligent contract, if the intelligent contract runs, the state of the intelligent contract is returned to update the intelligent contract communication handle, and the process is finished; if the intelligent contract is not operated, entering a Container module in the Runtime module to start the intelligent contract;
in operation 304, a Container module in the intelligent contract running support module (i.e., runtime module) acquires relevant configuration parameters of the intelligent contract, assembles the configuration parameters to generate an intelligent contract starting request, and invokes a virtual machine controller module (i.e., VMController module);
in operation 305, the virtual machine controller module (i.e., VMController module) calls a Docker virtual machine (i.e., docker VM) registered in the Docker-based container controller module (i.e., docker controller module) according to the relevant configuration parameters of the intelligent contract, and simultaneously generates a Docker file and creates an intelligent contract image dependent package through the Platforms module;
in operation 306, an intelligent contract is created based on a Docker virtual machine in a Docker container controller module (i.e., docker controller module), a relevant certificate file is newly added to the intelligent contract, and the intelligent contract is started to complete the intelligent contract starting process. Specifically, in the Docker mode, the starting process of the intelligent contract is as follows: generating an image file and creating an image, creating an intelligent contract, updating a certificate file of the intelligent contract into a container, and operating an intelligent contract container.
It can be seen from the above-mentioned overall process of creating, starting, and deploying an intelligent contract in the prior art that the core operations such as creating, starting, deploying, and stopping an intelligent contract are all implemented by a Docker virtual machine in a Docker controller module, an interface standard of a virtual machine VM is defined in a VMController, and a plug-in virtual machine can be implemented by using the interface standard, which makes it possible to implement core operations such as creating, starting, deploying, and stopping an intelligent contract based on another framework or a management platform.
In view of the powerful functions of kubernets, the management capability of the intelligent contract container can be improved by newly building a set of kubernets-based container controller module (i.e., kubeController module), which includes a kubernets-based virtual machine (i.e., kubeVM) 401 for managing the intelligent contract and a Provider module 402 for creating a kubernets-based virtual machine, see fig. 4, instead of the DockerController module and the Provider module and Docker virtual machine included therein in the prior art.
Fig. 5 schematically illustrates an intelligent contract management system 500 in a blockchain according to an embodiment of the present disclosure, where the management system includes a kubernets-based container controller module (i.e., kubeController module) 501.
The Kubernetes-based container controller module 501 is a core module for deploying and operating intelligent contracts, and is used for implementing an operation method of an intelligent contract container by using a Kubernetes platform, wherein the operation method of the intelligent contract container comprises creation, operation, closing or removal of the intelligent contract container. The Kubernetes-based container controller module is also used for packaging access to the Kubernetes API through a k8s.io/client-go package provided by a Kubernetes platform, and calling of the Kubernetes is achieved.
The kubernets-based container controller module 501 includes a Provider module 5011 and a kubernets-based virtual machine (i.e., kubeVM) 5012, wherein:
the Provider module 5011 is used for creating a virtual machine 5012 based on Kubernetes;
the virtual machine 5012 based on the kubernets is used for realizing an operation method of an intelligent contract container, the operation method of the intelligent contract container comprises the steps of creating, running, closing or removing an intelligent contract, and the access to the kubernets API is packaged through a k8s.io/client-go package provided by a kubernets platform, so that the call to the kubernets is realized.
The creating of the intelligent contract specifically comprises the following steps: and calling a virtual machine 5012 based on Kubernetes to create an intelligent contract, newly adding a related certificate file for the intelligent contract, and starting the intelligent contract.
Further, the Provider module 5011 and the kubernets-based virtual machine 5012 are registered in advance in the virtual machine controller module 503.
Because the Docker itself can be used as an infrastructure of a Kubernets cluster environment, the Kubecontroller can be directly reused in the flows of mirror image creation and the like related to the conventional Docker, thereby reducing the transformation difficulty.
However, in the aspect of embedding a certificate, an original Docker mode in the prior art is different from a kubernets mode, and a starting process of an intelligent contract in the Docker mode is as follows: generating an image file and creating an image, creating an intelligent contract, updating a certificate file of the intelligent contract into a container, and operating an intelligent contract container. However, the updating of the container cannot be performed in the kubernets mode, so that the certificate files need to be packaged into the mirror image together at first and then directly run, the adjusted process in the kubernets mode, that is, the virtual machine 5012 based on the kubernets is called to create the intelligent contract, the related certificate file is newly added to the intelligent contract, and the intelligent contract is started, which specifically includes: generating an image file, adding a new certificate file for the intelligent contract, updating the certificate file to the image file, creating an image, calling a Kubernetes-based virtual machine to create the intelligent contract, and calling the Kubernetes to operate an intelligent contract container.

Based on the overall architecture in fig. 4 and 5, fig. 6 schematically illustrates an intelligent contract management method in a blockchain provided by an embodiment of the present disclosure, where the method includes the following operations:
at operation 606, a kubernets-based container controller module implements a method of operating an intelligent contract container using a kubernets platform. The operation method of the intelligent contract container comprises the creation, the running, the closing or the removal of the intelligent contract container.
Further, the method for implementing the operation of the intelligent contract container by using the kubernets platform specifically includes: the Kubernetes-based container controller module invokes a Kubernetes-based virtual machine to create, run, close, or remove smart contracts.

Because the Docker itself can be used as an infrastructure of a Kubernets cluster environment, the Kubecontroller can be directly reused in the flows of mirror image creation and the like related to the conventional Docker, thereby reducing the transformation difficulty.
However, in the aspect of embedding a certificate, an original Docker mode in the prior art is different from a kubernets mode, and a starting process of the intelligent contract in the Docker mode is as follows: generating an image file and creating an image, creating an intelligent contract, updating a certificate file of the intelligent contract into a container, and operating an intelligent contract container. However, the updating of the container cannot be performed in the kubernets mode, so that the certificate files need to be packaged into the mirror image together at first and then directly run, the adjusted process in the kubernets mode, that is, the virtual machine based on the kubernets is called to create the intelligent contract, the related certificate file is newly added to the intelligent contract, and the intelligent contract is started, specifically including: generating an image file, adding a new certificate file for the intelligent contract, updating the certificate file to the image file, creating an image, calling a Kubernetes-based virtual machine to create the intelligent contract, and calling the Kubernetes to operate an intelligent contract container.
Meanwhile, the mirror image is only created locally, and the mirror images of other machines cannot be acquired in the cluster environment, so the Node Name Kube _ Node _ Name of the starting host is added into the Node environment variable and is used for setting the starting position of the intelligent contract; therefore, the invoking a virtual machine based on kubernets to create an intelligent contract, newly adding a related certificate file to the intelligent contract, and starting the intelligent contract further includes: adding the Node Name Kube _ Node _ Name of the starting host machine into the Node environment variable to set the starting position of the intelligent contract.
In addition, in kubernets, all nodes in a set of blockchain networks may be grouped into a set of centralized management in a namespace manner, so that the invoking of a virtual machine based on kubernets creates an intelligent contract, adds a new related certificate file for the intelligent contract, and starts the intelligent contract, further including: and adding a name parameter Kube _ Namespace of the currently located Namespace into the node environment variable, so that the intelligent contract container is added into the grouping of the block chain network, and the centralized and unified management of the contract container is facilitated.
The method further comprises:
in operation 605, when the virtual machine controller module (i.e., the VMController module) determines that the kubernets intelligent contract configuration is opened, the operation 606 is executed, that is, the kubernets-based container controller module uses the kubernets platform to implement the operation method of the intelligent contract container.
Before performing the operation 606, the virtual machine controller module generates a Dockerfile file through a platform modules module and creates an intelligent contract mirror dependency package.
Further, the operation 605 further comprises:
when the virtual machine controller module judges that the Kubernets intelligent contract configuration is not started, the operation 607 is executed, a Dockerfile file is generated through the platform modules, and an intelligent contract mirror image dependency package is created.
At operation 607, the Docker-based container controller module invokes the registered Docker virtual machine to implement the operation method of the intelligent contract container. The operation method of the intelligent contract container comprises the steps of creating, running, closing or removing the intelligent contract container.
The creating of the intelligent contract container specifically comprises: and calling a Docker virtual machine to create an intelligent contract, newly adding a related certificate file for the intelligent contract, and starting the intelligent contract. Further, the invoking a Docker virtual machine to create an intelligent contract, newly adding a related certificate file to the intelligent contract, and starting the intelligent contract specifically includes: generating an image file and creating an image, calling a Docker virtual machine to create an intelligent contract, updating a certificate file of the intelligent contract into a container, and operating the intelligent contract container.
Further, whether Kubernets intelligent contract configuration is started or not is judged by setting a conditional configuration parameter Kube _ Enable = true or false. Specifically, when Kube _ Enable = true is judged, kubernets intelligent contract configuration is determined to be started; when Kube _ Enable = false is judged, it is determined that kubernets smart contract configuration is not opened.
Prior to the operation 605, the method further includes operations 601-604:
in operation 601, receiving an intelligent contract deployment or execution request sent by a client;
in operation 602, the intelligent contract support module processes the request according to the type of the request, checks whether an intelligent contract communication handle exists in the handle management module, and if the intelligent contract communication handle does not exist in the handle management module, enters a Runtime module to create an intelligent contract and update the communication handle;
in operation 603, the Launcher module in the intelligent contract running support module checks the running state of the intelligent contract, if the intelligent contract runs, the intelligent contract state is returned to update the intelligent contract communication handle, and the process is finished; if the intelligent contract is not operated, entering a Container module in the intelligent contract operation supporting module to start the intelligent contract;
