技术领域
本申请涉及云计算技术领域，尤其涉及一种应用改造方法、应用管理系统以及计算机集群、计算机可读存储介质、计算机程序产品。
背景技术
云计算(cloud computing)也称作网络计算，是一种基于互联网的计算方式。通过该计算方式，可以将共享的软硬件资源按需提供给用户。将应用部署在云环境，一方面可以根据应用的负载按需获取资源进行灵活部署，提升资源利用率，另一方面可以节省自行构建数据中心的开销，以及维护数据中心的开销，降低成本。
考虑到云环境部署灵活、成本低的优势，越来越多的应用尤其是大型的信息技术(information technology，IT)应用(例如各种功能的信息管理系统)在进行容器化改造，从而实现向云环境迁移。其中，容器化改造是指将应用改造成容器，以便于迁移上云。目前，业界主流的改造方案是开发者基于自身经验和能力手动对应用进行改造。具体地，开发者将应用的安装包改造为适合在云环境部署的格式，例如是镜像格式。该镜像格式的文件即为应用的镜像。基于应用的镜像可以在云环境中创建应用的容器，从而实现应用迁移。
然而，上述改造方案依赖于开发者自身的经验和能力，导致改造效率不高，而且难以保证可靠性。如何提供一种可靠的、自动化的应用改造方法成为亟待解决的问题。
发明内容
本申请提供了一种应用改造方法，该方法基于应用在运行环境中的环境变量以及应用的代码包实现了自动化的应用改造，减少了人工介入，提高了应用改造的效率，避免了依赖于开发者经验导致可靠性难以得到保障的问题。此外，该方法改造应用获得包括多个镜像的镜像集，可以实现应用的微服务化，避免了应用因单点故障而无法提供服务，提升了服务的质量和可靠性。本申请还提供了上述方法对应的应用管理系统、计算设备集群、计算机可读存储介质以及计算机程序产品。
第一方面，本申请提供了一种应用改造方法。该方法可以由应用管理系统执行。 应用管理系统包括处理器和存储器。处理器用于执行存储器中存储的指令，以执行本申请的应用改造方法。下面对应用改造方法进行说明。
具体地，应用管理系统可以获取应用在运行环境中的环境变量和应用的代码包，其中，环境变量是指操作系统中具有特定名字的对象，环境变量包括一个或多个应用所使用的信息，用于在操作系统中指定应用的运行环境。然后应用管理系统可以根据上述环境变量和代码包，获得应用的改造结果。该改造结果包括应用的镜像集，镜像集包括多个镜像，根据各镜像创建的容器可以用于执行应用的部分模块。
一方面，该方法基于环境变量和代码包实现了自动化的应用改造，减少了用户手动介入，提高了应用改造的效率，避免了依赖于开发者经验导致可靠性难以得到保障的问题；另一方面，该方法对应用进行改造获得包括多个镜像的镜像集，进而实现应用的微服务化，如此可以避免应用因单点故障而无法提供服务，提高了服务的质量和稳定性。
在一些可能的实现方式中，应用的代码包可以为源码包，该源码包指示未经过编译处理的代码包。应用管理系统直接基于源码包进行容器化改造，通过对源码包进行分析，可以精准地获得镜像集的多个镜像，保障镜像的可用性和可靠性。
在一些可能的实现方式中，应用管理系统可以分析所述环境变量获得静态环境配置信息，以及分析所述源码包获得容器配置信息。其中，所述容器配置信息包括所述源码包的分块信息，所述分块信息用于将所述源码包分为多个代码块。该分块信息可以包括各个代码块的行标识，如起始行号和终止行号。相应地，应用管理系统可以根据所述静态环境配置信息和所述容器配置信息，获得所述应用的镜像集。该镜像集中每一镜像是根据所述静态环境配置信息和所述多个代码块中的至少一个代码块确定的。
其中，应用管理系统可以基于代码开发逻辑，通过人工智能技术，例如是自然语言处理对源码包中的代码进行识别，从而获得源码包的分块信息。例如，应用管理系统可以通过自然语言处理识别代码中各函数的语义，从而对源码包分块，获得源码包的分块信息。
该方法中，应用管理系统通过对源码包进行分块，一方面可以获得多个镜像，由此可以实现应用的微服务化，避免单点故障导致无法对外提供服务，另一方面可以实现精准分块，如此拆分得到的多个镜像更合理，具有较高可用性。
在一些可能的实现方式中，所述镜像集中的至少一个镜像是根据所述静态环境配置信息和所述分块信息，从镜像库中查找得到。具体地，镜像库中包括多个应用的镜像集，每个应用的镜像集包括至少一个镜像。应用管理系统可以根据静态环境配置信息和由分块信息确定的至少一个代码块，查找镜像库，获得查找到的应用的至少一个镜像。
其中，应用的镜像集中的各个镜像在镜像库中命中时，应用管理系统可以直接从镜像库获得应用的镜像集。当根据静态环境配置信息和由分块信息确定的至少一个代码块查找镜像库，存在未查找到的镜像时，应用管理系统还可以根据静态环境配置信息和由分块信息生成相应的镜像。
由于至少一个镜像可以从镜像库中获得，减少了生成该镜像所需要消耗的资源，以及减少了获取该镜像的时间，如此提高了应用改造的效率。
在一些可能的实现方式中，应用还可以引用外部组件，该外部组件是指第三方组件。应用管理系统可以分析所述源码包获得外部组件配置信息，其中，外部组件配置信息用于获得外部组件。该外部组件配置信息例如可以是外部组件的网络地址或存储地址。然后应用管理系统可以根据所述外部组件配置信息获取外部组件。例如，应用管理系统可以基于外部组件的网络地址或存储地址，调用或访问外部组件，从而实现获取外部组件。该外部组件与镜像集中的至少一个镜像关联。对应地，应用的改造结果还可以包括所述外部组件与所述镜像集中的至少一个镜像的关联关系。
该方法通过分析源码包获得外部组件配置信息，可以实现对引用外部组件的应用进行自动化改造，具有较高可用性。
在一些可能的实现方式中，镜像集中的镜像与承载镜像的容器通常是一一对应的。基于此，应用管理系统可以根据外部组件与所述镜像集中的至少一个镜像的关联关系，确定承载各镜像的容器与所述外部组件的关联关系。如此可以为后续应用迁移到云环境提供帮助。
在一些可能的实现方式中，应用管理系统还可以获取所述应用在所述运行环境中运行时的运行代码，获得运行时环境配置信息。所述运行时环境配置信息包括所述应用在所述运行环境中运行时所关联的基础关联包。该基础关联包可以是基础依赖包(如tomcat、Java、mvn)、编译相关的包(如gcc、glib或者make)、安装相关的包(如expect组件、py的引用库)中的一个或多个。
相应地，应用管理系统可以根据所述静态环境配置信息、所述运行时环境配置信息和所述容器配置信息获得所述应用的镜像集。其中，镜像集中至少一个镜像可以是根据所述静态环境配置信息、所述多个代码块中的至少一个代码块以及所述基础关联包确定。
该方法通过对应用在运行环境中运行时的运行代码进行分析，获得运行时环境配置信息。结合该运行时环境配置信息获得应用的镜像，可以提高获得的应用的镜像的准确度，满足了业务需求。
在一些可能的实现方式中，容器配置信息还包括各代码块之间的调用关系，所述改造结果还包括所述各代码块之间的调用关系。各代码块之间的调用关系可以指示各代码块对应的镜像之间的调用关系，进而指示承载镜像的容器之间的调用关系，如此可以为应用迁移到云环境提供帮助。
在一些可能的实现方式中，应用管理系统可以向用户呈现配置界面，该配置界面提供了多种源码包名称，应用管理系统可以接收所述用户在所述配置界面选择的所述应用的源码包名称，然后从软件仓库获取所述选择的所述应用的源码包名称对应的源码包，其中，软件仓库包括多个源码包。
该方法支持用户自行选择用于应用改造的源码包，如此，可以满足用户的个性化需求。
在一些可能的实现方式中，应用管理系统还可以接收用户上传的所述应用的源码包。用户上传的应用的源码包可以是用户自研应用的源码包或者是其他非开源应用的源码包，如此可以实现对自研应用或非开源应用的改造。

附图说明
为了更清楚地说明本申请实施例的技术方法，下面将对实施例中所需使用的附图作以简单地介绍。
图1为本申请实施例提供的一种应用改造方法的系统架构图；
图2为本申请实施例提供的一种配置界面的示意图；
图3为本申请实施例提供的一种应用改造方法的流程图；
图4为本申请实施例提供的一种应用的依赖图谱的示意图；
图5为本申请实施例提供的一种计算设备集群的结构示意图。
具体实施方式
本申请实施例中的术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。
为了便于理解本申请实施例，首先，对本申请涉及的部分术语进行解释说明。
应用(application，APP)，是指针对用户的某种特殊应用目的所撰写的计算机程序。应用可以按照应用目的或功能划分为不同类型，例如应用可以包括电子商务应用、社交应用、办公应用、休闲娱乐应用等类型。
镜像(image)，是指包括多个只读层(read-only layer)的联合文件系统(union file system)。该联合文件系统能够将不同的只读层整合成一个文件系统，为这些只读层提供一个统一的视角，这样就隐藏了多层的存在，从用户的角度看来，镜像存在一个只读文件系统。镜像提供运行应用所需元素的轻量级代码包。镜像可以理解为使用应用时需要获得的一种特定格式的安装包。其中，特定格式例如可以是光盘镜像文件(IsoBuster，ISO)格式。
容器(container)，是指通过镜像创建的运行实例。该运行实例可以是包括至少一个只读层和一个读写层(read-write layer)的联合文件系统。该联合文件系统能够将上述至少一个只读层和一个读写层整合成一个文件系统，从而为这些只读层提供一个统一的视角，这样就隐藏了多层的存在，从用户的角度看来，容器存在一个可读写的文件系统。容器运行应用所需元素的轻量级代码包，以实现操作系统级别的虚拟化，从而使得应用运行于相对独立和隔离的环境，简化了应用的部署流程，增强了应用的可移植性和安全性。
应用可以根据是否进行容器化分为容器化的应用和非容器化的应用。很多传统应用(例如考勤管理系统、生产管理系统)属于非容器化的应用。随着云计算技术的不断发展，越来越多的开发者选择将非容器化的应用改造(remodel)为容器化的应用，以实现将应用迁移到云环境中，从而提升容错性以及降低管理成本。
目前，业界主流的改造方案是，开发者基于自身经验和能力，将上述非容器化的应用的安装包改造为适合在云环境部署的格式，以在云环境中部署改造后的安装包，从而实现将应用迁移到云环境。然而，这种改造方案依赖于开发者自身的经验和能力，导致迁移效率不高，而且可靠性难以得到保障。
有鉴于此，本申请实施例提供了一种应用改造方法。该方法可以由应用管理系统执行。其中，应用管理系统可以是具有应用管理功能(例如是应用改造功能)的系统，该系统包括处理器和存储器，其中，处理器用于执行存储器中存储的指令，以执行应用改造方法。
具体地，应用管理系统获取应用在运行环境对应的环境变量和应用的代码包，然后根据所述环境变量和所述代码包获得应用的改造结果。该改造结果包括应用的镜像集，镜像集包括多个镜像，根据各镜像创建的容器用于执行应用的部分模块。
一方面，该方法基于环境变量和代码包实现了自动化的应用改造，减少了用户手动介入，提高了应用改造的效率，避免了依赖于开发者经验导致可靠性难以得到保障的问题；另一方面，该方法对应用进行改造获得包括多个镜像的镜像集，进而实现应用的微服务化，如此可以避免应用因单点故障而无法提供服务，提高了服务的质量和稳定性。
进一步地，在对应用进行容器化改造时，还可以基于源码包和环境变量直接进行容器化改造。其中，源码包指示未经过编译处理的代码包。与基于应用的安装包进行改造相比，该方法直接基于应用的源码包和环境变量进行容器化改造，通过对源码包进行分析，可以精准地获得镜像集的多个镜像，保障镜像的可用性和可靠性。
本申请实施例的应用管理系统可以用于对不同类型的应用进行容器化改造，以实现应用迁移。例如，应用管理系统可以改造电子商务平台，获得包括多个镜像的镜像集，如此可以通过多个镜像创建多个容器，从而实现将电子商务平台由本地服务器迁移到云环境中，并且能够实现以微服务的方式对外提供服务。其中，本地服务器可以是应用所有者(例如是开发者)私有的服务器。云环境指示云服务提供商拥有的，用于提供计算、存储、通信资源的云计算设备集群。该云计算设备集群中包括至少一个云计算设备，云计算设备包括云服务器。
又例如，应用管理系统可以改造生产管理系统，获得生产管理系统的镜像集，通过镜像集中的多个镜像可以实现将生产管理系统迁移到云环境中。类似地，应用管理系统还可以改造游戏，获得游戏的镜像集，通过镜像集中的多个镜像可以实现将游戏迁移到云环境中。迁移到云环境中的应用可以通过云服务的形式向用户提供对应的服务。
为了使得本申请的技术方案更加清楚、易于理解，接下来将对本申请实施例的系统架构进行介绍。
参见图1所示的应用改造方法的系统架构图，应用管理系统100部署在云环境中，云环境指示云服务提供商拥有的，用于提供计算、存储、通信资源的云计算设备集群。该云计算设备集群包括至少一个云服务器。应用管理系统100可以集中部署在一个云服务器中，或者分布式地部署在多个云服务器中。应用200部署在本地服务器中。部署应用管理系统100的云服务器可以与部署应用200的本地服务器建立有通信连接。应用200还可以部署在云服务器中，下面以应用200部署在本地服务器为例进行介绍。
应用管理系统100用于对将部署在本地服务器中的应用200进行改造，以便将应用200迁移到云环境中。其中，应用管理系统100可以与应用200交互，从而实现对应用200的改造。在一些可能的实现方式中，应用管理系统100还可以与软件仓库300、镜像库400交互，以实现对应用200的改造。
软件仓库300用于提供至少一种应用的代码包。其中，代码包可以是源码包。该源码包指示未经过编译处理的代码包。
镜像库400用于提供至少一种应用的镜像集。其中，镜像集包括多个镜像。根据各镜像创建的容器用于执行应用的部分模块。
图1是以软件仓库300、镜像库400部署在不同的云计算设备集群中进行示例说明，在本申请实施例其他可能的实现方式中，软件仓库300、镜像库400也可以部署在同一云计算设备集群，或者是部署在本地服务器。
具体地，应用管理系统100获取应用200在运行环境中的环境变量和应用200的代码包，例如应用管理系统100可以接入应用200的运行环境，获得应用200在运行环境中的环境变量，并从软件仓库300获取应用200的代码包，该代码包可以是源码包。应用管理系统100根据上述环境变量和代码包获得应用200的改造结果。该改造结果包括应用200的镜像集。其中，根据镜像集中的各镜像创建的容器用于执行应用的部分模块。
需要说明的是，应用管理系统100也可以不通过软件仓库300获取应用200的代码包，而是直接接收用户上传的应用200的代码包。类似地，应用管理系统100也可以不通过镜像仓库400获取镜像，而是直接根据环境变量和源码包生成镜像。
以上对应用管理系统100与应用200、软件仓库300、代码仓库400的交互过程进行了详细说明，接下来对应用管理系统100内部结构以及交互过程进行介绍。
具体地，应用管理系统100包括多个部分，例如应用管理系统100可以包括多个子系统。进一步地，子系统可以包括多个模块。应用管理系统100内部的子系统和模块可以有多种划分方式，本申请不对其进行限制。
图1为一种示例性的划分方式，如图1所示，应用管理系统100包括应用感知子系统102和镜像管理子系统108。在一些可能的实现方式中，应用管理系统100还包括分析子系统104、配置子系统106、容器管理子系统110中的一个或多个。下面对各个子系统进行详细介绍。
应用感知子系统102用于获取应用200在运行环境中的环境变量和源码包。环境变量是指操作系统(operation system，OS)中具有特定名字的对象，环境变量包括一个或多个应用所使用的信息，用于在操作系统中指定应用200的运行环境。在一些实施例中，环境变量包括PATH、JAVA HOME或CLASS PATH中的一种或多种。其中，JAVA HOME用于指示JAVA命令对应的可执行文件的路径。PATH用于指示可执行文件的搜索范围。在配置PATH之后，无论在哪个目录下执行JAVA命令，均可以基于上述搜索范围搜索JAVA命令的可执行文件。CLASS PATH用于指定JAVA类所在的目录。环境变量还可以包括操作系统类型、操作系统版本、内核版本、操作系统基础依赖包或者操作系统运行参数等。操作系统运行参数为操作系统运行时的参数，例如为OS内核内部的信号量等。
在一些可能的实现方式中，应用感知子系统102可以包括环境感知模块和软件感知模块。环境感知模块用于接入应用200的运行环境，获取应用200在运行环境中的环境变量。软件感知模块用于获取应用200的代码包，例如是从软件仓库300获取应用200的源码包。
环境感知模块可以获取应用200的接入信息，例如获取应用200的网络地址(Internet Protocol address，IP)，以接入应用200，然后扫描应用200所在的本地服务器，获得环境变量。进一步地，应用200还可以对接入请求进行鉴权。基于此，该接入信息还可以包括身份信息，该身份信息可以包括用户名和密码，在一些实施例中，身份信息还可以包括指纹、声纹或者是虹膜等中的一种或多种。应用200基于上述身份信息进行鉴权，当鉴权 通过时，允许应用管理系统100(例如是应用管理系统100中应用感知子系统102的环境感知模块)接入应用200。
软件感知模块可以提供配置界面。配置界面可以是图形用户界面(graphical user interface，GUI)，也可以是命令用户界面(command user interface)。该配置界面可以向用户呈现多种代码包标识，其中，代码包标识可以是代码包名称。软件感知模块可以接收用户通过上述配置界面选择的应用200的代码包名称，从软件仓库300中获取用户选择的应用200的代码包名称对应的代码包。其中，软件仓库300中包括多个源码包，软件感知模块获取的代码包括可以是多个源码包中的一个。
下面以软件感知模块通过GUI获取应用200的源码包进行示例说明。
参见图2所示的配置界面的示意图，配置界面20呈现有软件仓库300中多个应用的源码包的属性信息202，该属性信息202包括源码包名称、适用操作系统以及源码包版本。配置界面20还包括源码包的选择控件204。用户可以基于源码包的属性信息202，通过该选择控件204选中一个或多个源码包。
当用户触发配置界面20上承载的确认控件206时，软件感知模块可以响应于该操作，生成源码包获取请求，该请求具体用于请求从软件仓库300获取用户选中的源码包。在一些实施例中，当用户触发配置界面20上承载的取消控件208时，则软件感知模块可以放弃执行获取应用200的源码包的操作。
镜像管理子系统108用于根据环境变量和源码包获得应用200的改造结果，该改造结果包括应用200的镜像集。该镜像集中包括多个镜像。根据各镜像创建的容器用于执行应用200的部分模块。例如，对于电子商务平台这一应用，根据改造所得的镜像集中各镜像创建的容器分别用于执行电子商务平台的用户管理模块、评价管理模块、订单管理模块、商品管理模块。
需要说明的是，镜像管理子系统108可以支持查找镜像库400的方式获得应用200的镜像。针对镜像库400中未查找到的镜像，镜像管理子系统108再生成相应的镜像。如此，可以减少不必要的镜像生成操作。
在一些可能的实现方式中，应用管理系统100还包括分析子系统104、配置子系统106和容器管理子系统110中的至少一个。该分析子系统104用于分析环境变量获得静态环境配置信息，以及分析源码包获得容器配置信息。
静态环境配置信息可以是应用200未运行情况下的环境配置信息。环境配置信息用于描述应用200对环境的需求。静态环境配置信息可以包括操作系统类型、操作系统版本或者PATH等中的一种或多种。需要说明的是，应用200的源码包中也可以包括操作系统类型等信息，应用管理系统100可以根据静态环境配置信息中的操作系统类型和从源码包中获得的操作系统类型进行校验，从而保障可靠性。
容器配置信息可以是用于生成应用200的容器的配置信息。其中，容器是基于镜像生成的。基于此，容器配置信息可以包括用于生成镜像的信息。在一些实施例中，容器配置信息可以包括源码包的分块信息。该分块信息用于将源码包分为多个代码块。该分块信息可以包括各个代码块的行标识，如起始行号和终止行号。以电子商务平台为例，分块信息可以是用户管理模块、评价管理模块、订单管理模块、商品管理模块对应的代码块的起始行号和终止行号。多个代码块中的至少一个代码块可以用于生成应用200的一个镜像。
分析子系统104可以基于代码开发逻辑，通过人工智能(artificial intelligence，AI)技术，例如是自然语言处理(natural language processing，NLP)，对源码包中的代码进行识别，从而获得源码包的分块信息。例如，分析子系统104可以通过NLP识别代码中各函数的语义，从而对源码包分块，获得源码包的分块信息。
相应地，镜像管理子系统108可以根据所述静态环境配置信息和所述容器配置信息，获得所述应用的镜像集。其中，镜像集中每一镜像是根据静态环境配置信息和多个代码块中的至少一个代码块确定的。具体地，镜像管理子系统108可以根据静态环境配置信息和至少一个代码块查找镜像库400，获得镜像集中的至少一个镜像。针对未查找到的镜像，镜像管理子系统108可以根据静态环境配置信息和至少一个代码块生成相应的镜像。例如，镜像管理子系统108可以根据静态环境配置信息获取基础镜像，该基础镜像例如可以是操作系统镜像。然后镜像管理子系统108编译至少一个代码块，并将编译后的代码块安装到操作系统镜像，从而获得相应的镜像。在一些实施例中，镜像管理子系统108还可以将生成的镜像发布至镜像库400，以便后续使用。
进一步地，容器配置信息还可以包括各代码块之间的调用关系。仍以电子商务平台为例，评价管理模块可以调用订单管理模块，从而实现订单评价。基于此，容器配置信息可以包括评价管理模块对应的代码块和订单管理模块对应的代码块之前的调用关系。相应地，改造结果还包括各代码块之间的调用关系。其中，代码块之间的调用关系以及代码块和镜像之间的对应关系可以用于确定镜像之间的调用关系。如此，承载镜像的容器运行时，可以基于镜像之间的调用关系，实现容器与容器之间的调用。
在一些可能的实现方式中，分析子系统104还用于获取应用200在运行环境中运行时的运行代码，通过分析该运行代码可以获得运行时环境配置信息。运行时环境配置信息包括应用200在所述运行环境中运行时所关联的基础关联包。该基础关联包可以是基础依赖包(如tomcat、Java、mvn)、编译相关的包(如gcc、glib或者make)、安装相关的包(如expect组件、py的引用库)中的一个或多个。基于此，镜像管理子系统108可以根据所述静态环境配置信息、所述多个代码块中的至少一个代码块以及所述基础关联包确定应用200的镜像。
进一步地，运行时环境配置信息还可以包括运行应用200时依赖的操作系统环境变量(如用于内核配置的sysctl、用于指示搜索范围的PATH，用于验证身份或状态的可动态加载验证模块(pluggable authentication modules，PAM)、外部资源(如IP资源、计算资源、内存资源等)中的一种或多种。其中，在确定镜像之前，镜像管理子系统108还可以对静态环境配置信息和运行时环境配置信息进行校验，例如是对静态环境配置信息中的操作系统环境变量和运行时环境配置信息中的操作系统环境变量进行校验。当校验通过时，再确定应用200的镜像。
配置子系统106用于组装静态环境配置信息、运行时环境配置信息和容器配置信息生成镜像配置文件。该镜像配置文件用于描述生成镜像所需要的数据或资源。相应地，镜像管理子系统108可以根据由静态环境配置信息、运行时环境配置信息和容器配置信息组装的镜像配置文件，获得应用200的镜像集。
考虑到应用200引用外部组件(也可以称作第三方组件)的情况，分析子系统104还可以用于分析源码包，获得外部组件配置信息。其中，外部组件是指自有组件之外的组件， 外部组件例如可以是外部数据库，即第三方数据库。容器管理子系统110用于根据外部组件配置信息获取外部组件，该外部组件与镜像集中的至少一个关联。基于此，改造结果还可以包括外部组件与镜像集中的至少一个镜像的关联关系。
容器管理子系统110用于根据镜像集中的多个镜像分别创建容器，例如可以基于创建脚本，通过镜像集中的多个镜像分别创建容器，然后基于外部组件与镜像集中的至少一个镜像的关联关系，将外部组件与相应的容器关联，从而实现迁移应用200。其中，容器管理子系统110在创建容器时，可以通过容器平台创建应用200的容器。容器平台具体是一种将应用部署至云环境，并提供全栈的IT自动化运维能力的工具。
需要说明的是，图1是以应用管理系统100部署在云环境中进行示例说明，在本申请实施例其他可能的实现方式中，应用管理系统100也可以部署在边缘环境中。例如部署在边缘环境中的一个或多个计算设备(即边缘计算设备)上，边缘计算设备可以为服务器、计算盒子等。该应用管理系统100还可以部署在端设备中。其中，端设备包括但不限于台式机、笔记本电脑、智能手机或者本地服务器。应用管理系统100部署在本地服务器中时，可以与应用200部署在同一本地服务器或者部署在不同的本地服务器。
应用管理系统100的各个部分也可以分布式地部署在不同环境中。例如，可以在云环境、边缘环境、端设备中的三个环境，或其中任意两个环境上分别部署应用管理系统100的一部分。
上文对应用管理系统100的系统架构进行了详细说明，接下来，从应用管理系统100的角度对本申请实施例提供的应用改造方法进行详细说明。
参见图3所示的应用改造方法的流程图，该方法包括：
S302：应用管理系统100获取应用200在运行环境中的环境变量和应用200的源码包。
具体地，应用管理系统100可以接入应用200的运行环境，以获取应用200在运行环境中的环境变量。其中，环境变量为OS中具有特定名字的对象，例如是名字为PATH、JAVA HOME或CLASS PATH的对象，这些对象包括一个或多个应用所使用的信息，用于在OS中指定应用的运行环境。环境变量还可以包括操作系统类型、操作系统版本、内核版本、操作系统基础依赖包或者操作系统运行参数等。操作系统运行参数为操作系统运行时的参数，例如为OS内核内部的信号量等。
源码包是应用开发人员按照计算机语言如C语言、JAVA语言、Python语言等中的任意一种或多种程序设计语言编写的源代码形成的代码包。源码包是未经过编译处理的代码包，能够体现应用200的开发逻辑。应用管理系统100可以从软件仓库300获取源码包。具体地，应用管理系统100可以根据应用200的源码包标识查找软件仓库300，以获得与应用200的源码包标识匹配的源码包。其中，源码包标识可以是源码包名称。应用管理系统100可以向用户呈现配置界面，然后接收用户通过配置界面选择的源码包标识，从而根据该源码包标识查找软件仓库300，获得相应的源码包。
S304：应用管理系统100分析环境变量，获得静态环境配置信息。
静态环境配置信息可以是应用200未运行情况下的环境配置信息。环境配置信息用于描述应用200对环境的需求。静态环境配置信息可以包括操作系统类型、操作系统版本或者PATH等中的一种或多种。
应用管理系统100可以从环境变量中提取应用200对环境的需求，该需求可以是应用200对操作系统、计算资源的需求，然后应用管理系统100可以根据该需求，获得静态环境配置信息。
S306：应用管理系统100分析源码包，获得容器配置信息。
容器配置信息可以是用于生成容器的配置信息。其中，容器是基于镜像生成的运行实例。因此，容器配置信息包括用于生成镜像的信息。在一些实施例中，容器配置信息可以包括源码包的分块信息。该分块信息用于将源码包分为多个代码块。该分块信息可以包括各个代码块的行标识，如起始行号和终止行号。
具体实现时，应用管理系统100可以基于代码开发逻辑，通过AI技术，例如是NLP对源码包中的代码进行识别，从而获得源码包的分块信息。例如，应用管理系统100中的分析子系统104可以通过NLP识别代码中各函数的语义，从而对源码包分块，获得源码包的分块信息。
进一步地，应用管理系统100分析源码包中函数之间的调用关系，从而获得各代码块之间的调用关系。相应地，容器配置信息还可以包括各代码块之间的调用关系。以电子商务平台为例，容器配置信息还可以包括用户管理模块、评价管理模块、订单管理模块、商品管理模块对应的代码块之间的调用关系。该调用关系可以反映应用200的上下游依赖关系。
此外，容器配置信息还可以包括服务配置信息和/或基础关联包。该服务配置信息包括对外服务IP、周边组件(如数据库、缓存、消息队列)的IP中的一种或多种。基础关联包可以包括基础依赖包(如tomcat、Java、mvn)、编译相关的包(如gcc、glib或者make)、安装相关的包(如expect组件、py的引用库)中的一个或多个。
其中，容器配置信息可以通过关系图谱进行表达。为了便于区分，本申请将容器配置信息对应的关系图谱称作应用依赖图谱。其中，应用管理系统100可以以记录有分块信息、服务配置信息的配置文件以及基础依赖包等为节点，构建应用依赖图谱。
S308：应用管理系统100获取应用200在所述运行环境中运行时的运行代码，获得运行时环境配置信息。

应用管理系统100先获取应用200在运行环境中运行时的运行代码，然后对运行代码进行分析，例如通过AI技术对运行代码进行分析，从而获得运行时环境配置信息。
由于运行时环境配置信息中包括操作系统环境变量等信息，基于此，应用管理系统100还可以根据运行时环境配置信息和静态环境配置信息对包括操作系统环境变量在内的信息进行二次校验，校验成功后，再执行S312。
类似地，运行时环境配置信息中包括应用200运行时的基础关联包(例如基础依赖包)。 基于此，应用管理系统100还可以根据运行时环境配置信息和容器配置信息对基础关联包等进行二次校验，校验成功后，再执行S312。
其中，运行时环境配置信息可以通过关系图谱表征。为了便于区分，运行时环境配置信息对应的关系图谱可以称作环境依赖图谱。具体地，应用管理系统100可以以环境变量为节点，构建环境依赖图谱。
需要说明的是，应用管理系统100还可以根据应用依赖图谱和环境依赖图谱，生成应用200的依赖图谱。参见图4所示的依赖图谱的示意图，对于待进行容器化改造的应用，基于静态环境和运行时环境生成的图谱为环境依赖图谱，基于源码包生成的图谱为应用依赖图谱。
环境依赖图谱描述了应用对静态环境的要求，例如内核要求、文件系统要求等，其中，内核要求包括内核参数sysctrl、环境变量Path、信号量、端口或者LD链接，文件系统要求包括文件系统的类型、大小(图中未示出)等等。应用对静态环境的要求还可以包括系统配置。该系统配置包括应用的域名、系统要求、网络世界协议(Network Time Protocol，NTP)要求。
环境依赖图谱还描述了应用对运行时环境的要求。其中，应用对运行时环境的要求包括对周边组件的依赖。该周边组件具体可以包括消息队列(message queue，MQ)、缓存(例如Redis)、数据库等。
应用依赖图谱描述了通过对应用的源码包分析所确定的框架、应用命令以及软件依赖。其中，框架可以包括SpringCloud、Dubbo等。软件依赖可以包括依赖模块(如基础依赖库)、配置文件等。
应用管理系统100通过将上述应用依赖图谱和上述环境依赖图谱进行拼接，可以得到相对完整的依赖图谱。
S310：应用管理系统100分析源码包，获得外部组件配置信息。
外部组件，即第三方组件。应用管理系统100可以基于应用的开发逻辑，分析源码包中的源代码，确定源码包中引用的外部组件，根据引用的外部组件的信息，如外部组件的标识，获得外部组件配置信息。外部组件配置信息用于获得外部组件。基于此，外部组件配置信息例如可以是外部组件的IP或外部组件的存储地址。例如，外部组件为外部数据库时，外部组件配置信息可以是外部数据库的IP。又例如，外部组件为外部操作组件时，外部组件配置信息可以是外部操作组件的存储地址。
需要说明的是，上述S304至S310为本申请实施例的可选步骤，在本申请实施例其他可能的实现方式中，应用管理系统100也可以不执行S304至S310，或者是执行S304至S310中的一个或多个步骤。
S312：应用管理系统100组装静态环境配置信息、运行时环境配置信息和容器配置信息，获得镜像配置文件。
镜像配置文件用于指示生成镜像。具体地，应用管理系统100可以根据镜像配置文件的模板，填充静态环境配置信息、运行时环境配置信息以及容器配置信息，从而获得镜像配置文件。
需要说明的是，上述S310、S312为本申请实施例的可选步骤，应用管理系统100也可以不执行S310、S312中对获得外部组件配置信息以及获得相应外部组件的步骤。应用 管理系统100可以根据静态环境配置信息和容器配置信息进行组装获得镜像配置文件。
S314：应用管理系统100根据镜像配置文件，获得应用200的镜像集。
镜像集中包括多个镜像。每个镜像可以根据镜像配置文件中的静态环境配置信息、运行时环境配置信息和容器配置信息确定。具体地，应用管理系统100可以根据静态环境配置信息、运行时环境配置信息和容器配置信息(例如是容器配置信息中的分块信息)，查找镜像库400，获得至少一个镜像。
当基于分块信息确定的各个代码块对应的镜像在镜像库400中命中时，应用管理系统100可以获得应用200的镜像集。当基于分块信息确定的多个代码块中至少有一个代码块对应的镜像未在镜像库400中命中时，应用管理系统100可以根据静态环境配置信息、运行时环境配置信息和至少一个代码块生成相应的镜像。
下面对应用管理系统100生成镜像的过程进行详细说明。
首先，应用管理系统100可以根据环境配置信息中与操作系统相关的信息，如操作系统名称、操作系统版本等，获取基础镜像，也即操作系统镜像。其中，环境配置信息可以是静态环境配置信息或运行时环境配置信息中的至少一个。在一些实施例中，应用管理系统100还可以对静态环境配置信息和运行时环境配置信息进行校验，例如应用管理系统100可以比较静态环境配置信息中的操作系统相关信息和运行时环境配置信息中的操作系统相关信息，当比较结果为一致时，则校验通过，可以根据该操作系统相关信息获得操作系统镜像。接着应用管理系统100可以编译由容器配置信息中的分块信息划分的多个代码块中的至少一个代码块，然后将编译后的代码块安装至相应的操作系统镜像，从而获得应用200的镜像。
需要说明的是，上述S314为应用管理系统100根据环境变量和源码包获得应用200的镜像的一种具体实现，执行本申请实施例的应用改造方法也可以通过其他方式获得应用200的镜像集。
S316：应用管理系统100根据外部组件配置信息获取外部组件。
考虑到应用200引用外部组件的情况，应用管理系统100可以根据外部组件配置信息获取外部组件。其中，外部组件配置信息可以包括外部组件的IP或者存储地址，应用管理系统100可以根据外部组件的IP或存储地址等，获取外部组件。例如，外部组件为外部数据库时，应用管理系统100可以通过外部数据库的IP，访问该外部数据库。
其中，外部组件与应用200的镜像集中的至少一个镜像关联。应用200的改造结果还包括外部组件与所述镜像集中的至少一个镜像的关联关系。
S318：应用管理系统100根据应用200的镜像集创建多个容器，并将外部组件与多个容器中的至少一个容器关联。
具体地，应用管理系统100可以和容器平台对接，然后借助该容器平台，对应用200的镜像集中的各镜像分别执行创建容器的操作，获得与各镜像对应的容器。接着，应用管理系统100可以将外部组件与至少一个容器关联，从而实现将应用200迁移到云环境。其中，与外部组件关联的至少一个容器是基于引用该外部组件的代码块对应的镜像创建的容器。应用管理系统100可以基于外部组件与至少一个镜像之间的关联关系以及镜像和容器之间的对应关系，确定外部组件和容器之间的关联关系，进而将外部组件与相应的容器关联。
上述S316至S318为本申请实施例中对应用200进行迁移的一种具体实现，在本申请实施例其他可能的实现方式中，应用管理系统100也可以不执行上述S316至S318，例如应用管理系统100可以直接根据镜像集中的镜像分别创建容器，从而实现迁移应用200。
需要说明的是，图3所示实施例是以基于应用200的源码包改造应用200进行示例说明。在本申请实施例其他可能的实现方式中，应用管理系统100也可以基于应用200的其他代码包，如安装包等对应用200进行改造。
