[0033] Step S1: Provide iSulad container engine related configuration templates, patches, and executable scripts.

[0034] Configuration template: A basic configuration file prepared for the iSulad container engine, including various required settings.

[0035] Patch: Code changes developed to fix and enhance the open source Hongmeng system to support the iSulad container engine.

[0036] Step S2: Distribute and execute script commands.

[0039] Step S3: Recompile the entire system to obtain a burnable image file.

[0040] After applying all changes, recompile the entire system; this step will generate a burnable image file for installing and running the open source Hongmeng system with the iSula container on the device.

[0041] The iSulad container engine provides two external interfaces, CLI command line and NAPI, on the open source Hongmeng system for users to use, including container management, image management, network management, storage management, log management and application management.

[0042] Working principle: This application successfully ported the iSulad container engine to the open source Hongmeng system and provided two interfaces: CLI command line and NAPI. It completed the compatibility porting of the iSulad container engine on the open source Hongmeng system; helped the iSula container application to migrate and use smoothly on the open source Hongmeng system, effectively promoted the development of the entire container ecosystem of the open source Hongmeng; expanded the application scenarios of the iSulad container engine, enabling it to be developed under the open source Hongmeng system.

[0043] The other parts of this embodiment are the same as those of the above-mentioned embodiment 1, and thus will not be described in detail.

[0044] Embodiment 3: This embodiment is based on any one of the above embodiments 1 to 2. Figure 3 As shown, Figure 3 The directory shown is described.

[0045] Step S1: Provide iSulad container engine related configuration templates, patches and executable scripts; Configuration templates: including the iSula container image repository configuration template isula_hub_config.json, the iSula container operation configuration template isula_config.json, the iSula container management configuration template isula_config.v2.json, the iSula container APP information persistence configuration template isula_app_config.json, the iSulad container engine startup service configuration template openeuler_isulad.cfg on the open source Hongmeng system, and the iSulad container engine kernel configuration template isulad_standard_defconfig on the open source Hongmeng system.

[0046] Patch: Code changes developed to repair and enhance the open source Hongmeng system to support the iSulad container engine, including fixing the multi-process error problem that occurs when the iSulad container engine runs in the open source Hongmeng system in version 4.0 of the open source Hongmeng system. In addition, based on C++, the NAPI interface of the iSulad container engine is added in version 4.0 of the open source Hongmeng system to cover common container application scenarios. Its core functional interfaces include image management, container management, and application APP management.

[0047] Executable script: The script is executed according to Figure 3 The code directory structure shown in the figure is written to automate a series of steps and commands required in the migration process by executing scripts.

[0048] Step S21: Execute the first command of the script to convert the configuration template into Figure 3 Copy the code directory structure shown to the specified path, then enter the open source Hongmeng 4.0 version source directory, add the necessary directories for the iSula container to run, including: / data / isulad / [etc, bin, lib, run, var, opt, usr], and configure corresponding access permissions for these directories.

[0049] Step S22: Execute the second command of the script to apply the patch Figure 3Copy the code directory structure shown to the specified path, then enter the open source Hongmeng 4.0 version source directory to complete the patch operation in the current system. The patch is mainly divided into two parts. One part is to fix the multi-process error problem that occurs when the iSulad container engine runs in the open source Hongmeng system; the other part is to cancel the iSulad container engine's support for the CRI standard protocol, not provide an external K8S access interface, and add the iSulad container engine to the NAPI interface iSulad_interfaces implementation source code.

[0050] Step S23: Execute the third command of the script, modify the kernel configuration file, and enable the functional dependency of the iSula container. Modify the kernel features in the open source Hongmeng 4.0 version source code directory, and add the configuration items in the configuration file isulad_standard_defconfig to the current open source Hongmeng system kernel configuration file. Specifically, it mainly enables functions such as namespace, cgroup, network, and overlay filesystem in the open source Hongmeng system kernel.

[0051] Step S24: Execute the fourth command of the script to modify the system compilation script and add support for compiling other components of the iSulad container engine. Specifically, modify the open source Euler system compilation script and use Figure 3 The cross-compilation tool in the openharmony_prebuilts code directory shown in the figure; modify the open source Hongmeng system compilation script, specify the use of the same cross-compilation tool, and add the NAPI subsystem compilation option of iSulad, and Figure 3 Copy iSulad_interfaces in the code directory shown to the open source Hongmeng system source code directory, then add the BUILD.gn file and bundle.json file, and finally add the iSulad_interfaces subsystem to the system compilation options in the subsystem_config.json file.

[0052] Step S3: Recompile the entire system to obtain a burnable image file. Figure 3In the code directory shown, execute the iSulad_build.sh script, which will first check the relevant configuration files, directory structure and corresponding scripts. After the check is passed, it will enter the open source Euler system source code directory, compile the iSulad engine and components, and then enter the open source Hongmeng system source code directory after success. Copy the compiled iSulad engine and components to the system's corresponding / data / isulad directory, and then recompile the open source Hongmeng system. After successful compilation, the latest images that can be burned will be generated in the out directory of the open source Hongmeng system source code.

[0053] like Figure 2 This is an iSulad container engine software architecture diagram disclosed in this application. iSulad is a typical CS architecture model. It cancels the support of the CRI standard protocol and does not provide an external K8S access interface; it supports the CNI network standard protocol. Through the CNI protocol, iSulad communicates with specific network plug-ins through files in JSON format, thereby realizing the network function of the container; it supports the OCI standard image format and is compatible with the docker image format. It can support downloading container images from image repositories such as docker hub, or importing image files exported by docker; it supports the OCI standard runtime and can perform container lifecycle management. In addition to the above standards, it also provides standard basic image files, and implants the application management communication daemon by default, which communicates with the application management in JSON format through the MQTT protocol.

[0054] In the method of this application, iSulad, as a daemon server, provides two external interfaces, CLI command line and NAPI, for users to use, including container management, image management, network management, storage management, log management and application management. The CLI command line is the client command isula that comes with the iSulad engine; the NAPI access interface is implemented by calling the two services of iSulad's image and runtime through the interface, framework and service layer code according to the subsystem specifications in the open source Hongmeng system.

[0055] Specifically, image management includes: image downloading, importing, deleting, and upgrading operations.

[0056] Specifically, container management includes: container installation, uninstallation, start, stop, resource setting, and information query operations.

[0057] Specifically, network management includes: setting the IP address of the container.

[0058] Specifically, storage management includes: setting the storage path of the container's virtual disk file.

[0059] Specifically, log management includes: storage and query of log files inside the container.

[0060] Specifically, application management includes: application installation, uninstallation, start, stop, enable, disable, upgrade, resource setting, and information query operations.
