本发明实施例涉及容器技术领域，尤其涉及一种构建镜像的方法和装置。
背景技术
在当前云计算架构中，特别是PaaS平台架构，通过容器技术作为各类应用运行的载体，从而实现运维自动化、开发运维一体化(DevOps)、微服务架构等应用场景。在这些应用场景中，容器镜像构建技术是必不可少的一个环节。
现有技术中的容器镜像构建过程，需要开发或运维人员根据实际需要设计运行某一类应用程序的镜像，所以开发或运维人员必须在构建之前先学习容器镜像构建技术。由于用于运行不同的应用程序的镜像不同，不同镜像的构建过程也不同，而且在应用组件迁移到PaaS平台的过程中还涉及到与平台兼容性配置的问题，开发或运维人员不一定可以构建一个比较精简、有效且可以正常运行的镜像。
因此，亟需一种构建镜像的方法，实现自动构建镜像，减少开发或运维人员的学习成本。

附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简要介绍。
图1为本发明实施例提供的一种构建镜像的方法流程示意图；
图2为本发明实施例提供的包括属性文件的目录结构示意图；
图3为本发明实施例提供的另一种构建镜像的方法流程示意图；
图4为本发明实施例提供的一种用于构建镜像的装置的结构示意图。
具体实施方式
为了使本发明的目的、技术方案及有益效果更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明实施例的镜像构建方法适用于所有通过镜像构建脚本构建镜像的场景，主要涉及的镜像类型包括但不限于Docker容器类镜像。由于不同类型的应用程序的镜像不同，用于构建不同的镜像的模板文件也不同。为了避免每次构建镜像都需要编写用于构建镜像的所有信息，本发明实施例通过选择一个预先制定的目标应用所属的应用类型对应的模板文件，获取变量信息对应的待输入参数，并执行构建镜像命令，实现简化构建镜像过程。
图1示例性示出了本发明实施例提供的一种构建镜像的方法流程示意图。如图1所示，本发明实施例提供的构建镜像方法包括以下步骤：
步骤101：获取目标应用所属的应用类型对应的模板文件；模板文件包括平台环境配置信息和至少一个变量信息；
步骤102：获取至少一个变量信息对应的与所述目标应用匹配的待输入参数；
步骤103：根据平台环境的配置信息、至少一个变量信息和至少一个变量信息对应的与所述目标应用匹配的待输入参数，执行构建镜像命令得到用于运行目标应用的镜像。
本发明实施例中，获取目标应用所属的应用类型对应的模板文件；模板文件包括平台环境的配置信息和至少一个变量信息；获取至少一个变量信息对应的与目标应用匹配的待输入参数；根据平台环境配置信息、至少一个变量信息和至少一个变量信息对应的与目标应用匹配的待输入参数，执行构建镜像命令得到用于运行目标应用的镜像。如此，开发或运维人员只需要知道至少一个变量信息对应的与所述目标应用匹配的待输入参数，就可以实现自动构建运行目标应用类型的镜像，开发或运维人员无需学习镜像构建技术，可以减少学习成本。
本发明实施例中，获取目标应用所属的应用类型对应的模板文件的实现方式有多种。一种可选的实现方式为，制定一个通用型的模板文件，可以用来构建用于运行各种类型应用的镜像，各种类型应用可以但不限于以下类型：Java应用类型、PHP应用类型、Go/C/C++应用类型。另一种可选的实现方式为，制 定多份具有应用类型通用型的模板文件，也就是说，为每种类型应用制备模板文件，用于构建运行该类型应用的镜像；比如，针对Java应用类型，制备一个适用于Java应用类型的模板文件。
本发明实施例中，每个模板文件中包括用于运行目标应用类型的平台环境配置信息和至少一个变量信息。举个例子，目标应用为Java应用1，属于Java应用类型，与Java应用1属于同一应用类型的应用还有Java应用2和Java应用3，在构建用于运行Java应用1、Java应用2和Java应用3的镜像时，可以使用同一个Java应用类型的模板文件。
上述实施例中，平台环境配置信息为平台相关的配置项，比如平台的兼容性要求、平台的特殊性要求等配置内容。可选的，每个与目标应用所属的应用类型一致的应用的平台环境配置信息相同。也就是说，Java应用1、Java应用2和Java应用3的平台环境配置信息相同，不需要进行分别设置，所以可以在模板文件中预先设置，在构建目标应用的镜像时不需要将平台环境配置信息暴露给开发或运维人员，从而可以简化构建镜像过程，减少开发或运维人员工作量。
本发明实施例中，模板文件中的使用的语言有多种，本发明实施例以Go语言为例，以下提供一个包括变量信息的模板文件的示例。
示例1：
FROM{{.BaseImage}}
MAINTAINER{{.UserName}}
RUN{{.LinuxBaseCmd}}
COPY package/*/{{.AppName}}/
COPY script/run.sh{{.CmdDir}}
RUN rpm-ivh/{{.AppName}}/*.rpm&&rm-r/{{.AppName}}/*.rpm
COPY config/*{{.ConfigDir}}
RUN rm-fr{{.LogDir}}
RUN ln-sf/wae/log{{.LogDir}}
WORKDIR{{.Workdir}}
CMD["{{.CmdDir}}run.sh"]
上述示例1中，大括号{{.}}中的内容为至少一个变量信息，比如基础镜像(BaseImage)，用户名称(UserName)和Linux基本命令(LinuxBaseCmd)等。
基于步骤102，每个与目标应用所属的应用类型一致的应用的待输入参数不同。举个例子，比如在构建用于运行Java应用1的镜像时，需要获取Java应用1匹配的待输入参数；在构建用于运行Java应用2的镜像时，需要获取Java应用2匹配的待输入参数。在构建用于运行目标应用的镜像时，需要将模板文件中的至少一个变量信息暴露给开发或运维人员，开发或运维人员输入每个变量信息对应的与目标应用匹配的待输入参数。
本发明提供一种获取至少一个变量信息对应的与所述目标应用匹配的待输入参数的实现方式，将至少一个变量信息显示在Web页面或目标应用的属性文件中；在监测到Web页面或目标应用的属性文件中存在数据输入，则获取每个变量信息和每个变量信息对应的输入的数据组成的至少一对键值对；每对键值对包括的关键字为变量信息，值为该变量信息对应的与目标应用匹配的待输入参数。
可选的，属性文件包括但不限于JSON文件、XML文件、YAML文件等文件。若是将至少一个变量信息显示在属性文件中，以JSON文件为例，那么可以在文件展示的目录结构中查找到JSON文件，图2示例性示出了本发明实施例提供的包括属性文件的目录结构示意图。如图2所示，在目录结构中的父目录wplus-console的子目录中找到子目录info，再找到目录info的JSON文件appInfo.json，JSON文件中包括至少一个变量信息。
以下提供一个将变量信息展示在Web页面或属性文件中的示例。
示例2：
{
"BaseImage":,
"Namespace":,
"AppName":,
"Version":,
"UserName":,
"LogDir":,
"CmdDir":,
"ConfigDir":,
"Workdir":,
"LinuxBaseCmd":
}
上述示例2中，每一行包括一个变量信息，比如第一行包括变量信息：基础镜像(BaseImage)，第二行包括变量信息：命名空间(Namespace)等。
基于示例2，开发或运维人员在Web页面或属性文件中填写至少一个变量信息对应的与目标应用匹配的待输入参数，之后，获取以变量信息为关键字，以该变量信息对应的与目标应用匹配的待输入参数为值的键值对。
基于示例2中展示的变量信息，以下提供至少一对键值对的示例。
示例3：
{
"BaseImage":"registry.wae.haplat.net/base/java:7",
"Namespace":"wplus",
"AppName":"wplus-console",
"Version":"1.4.1-1",
"UserName":"huwh",
"LogDir":"/usr/local/wsop/console/logs",
"CmdDir":"/usr/local/bin/",
"ConfigDir":"/usr/local/wsop/console/conf/",
"Workdir":"/usr/local/wsop/console/",
"LinuxBaseCmd":"yum install–y file"
}
上述示例2中，每一行的中包括一对键值对，举个例子，比如第一行中， 关键字为变量信息：BaseImage，其值为：与目标应用匹配的待输入参数为registry.wae.haplat.net/base/java:7；再比如第二行中，关键字为变量信息：Namespace，其值为：与目标应用匹配的待输入参数为wplus。本发明实施例中向开发或运维人员暴露至少一个变量信息，开发或运维人员只需要输入至少一个变量信息对应的与目标应用匹配的待输入参数。如此，开发或运维人员不需要编写与平台相关的配置信息，无需关注不同的平台兼容配置问题，从而实现简单高效的自动化构建镜像过程。
本发明实施例中，构建镜像需要先创建一个镜像构建脚本。创建镜像构建脚本的过程并不需要开发和运维人员了解，可以根据平台环境的配置信息、至少一个变量信息和至少一个变量信息对应的与所述目标应用匹配的待输入参数，自动构建用于运行目标应用的镜像。
下面对本发明实施例如何自动创建镜像构建脚本并构建镜像过程进行详细介绍。
基于步骤102，在获取到与目标应用匹配的待输入参数之后，根据平台环境配置信息、至少一个变量信息和至少一个变量信息对应的与目标应用匹配的待输入参数，执行构建镜像命令得到用于运行目标应用的镜像，包括：根据目标应用所属的应用类型对应的模板文件，确定出每个变量信息在模板文件中的目标位置；将每个变量信息对应的与目标应用匹配的待输入参数填充至目标位置，并根据填充后的模板文件生成镜像构建脚本；根据镜像构建脚本执行构建镜像命令，得到用于运行目标应用的镜像。
结合示例1、示例3举个例子，在示例1中的模板文件中包括至少一条包括变量信息的命令，比如FROM{{.BaseImage}}，命令为：基于一个基础镜像构建用于运行目标应用的镜像。首先，确定出变量信息BaseImage在模板文件中的位置，作为目标位置；之后，获取示例3中变量信息BaseImage对应的待输入参数registry.wae.haplat.net/base/java:7，并将该待输入参数填充至示例1中的模板文件中变量信息BaseImage对应的目标位置，即可得到镜像构建脚本。如 此，可以简化构建镜像的过程，实现自动构建镜像。
本发明实施例中，所述模板文件中还包括所述至少一个变量信息对应的预设结构体；将每个变量信息对应的与目标应用匹配的待输入参数填充至目标位置之前，还包括：将获取的至少一对键值对解析成待匹配结构体；其中，待匹配结构体与预设结构体的格式一致。举个例子，当用户在AppInfo.json文件中输入至少一个变量信息对应的待输入参数时，即可通过json.Unmarshal函数将从AppInfo.json文件中获取的至少一个键值对解析成待匹配结构体。再将该待匹配结构体通过模板处理方式解析生成构建镜像脚本，其中模板处理方式可以通过text/template包或http/template包的模板处理功能实现。
本发明实施例提供一种确定出每个变量信息在所述模板文件中的目标位置，将每个变量信息对应的与目标应用匹配的待输入参数填充至目标位置得到镜像构建脚本的实施方式：将所述待匹配结构体中的每个变量信息与所述预设结构体中的每个变量信息进行匹配；若确定所述待匹配结构体中的变量信息与所述预设结构体中的变量信息一致，则：将所述预设结构体中的变量信息对应的位置确定为所述目标位置；将所述所述目标位置的变量信息删除，并将所述待匹配结构体中变量信息对应的与所述目标应用匹配的待输入参数填充至所述目标位置，得到镜像构建脚本。
本发明实施例中，镜像构建脚本不局限于Dockerfile文件，可以是任何镜像构建文件，以下提供一种根据示例3中的键值对和模板文件得到的镜像构建脚本的示例。
示例4：
FROM registry.wae.haplat.net/base/java:7
MAINTAINER huwh
RUN yum install-y file
COPY package/*/wplus-console/
COPY script/run.sh/usr/local/bin/
RUN rpm-ivh/wplus-console/*.rpm&&rm-r/wplus-console/*.rpm
COPY config/*/usr/local/wsop/console/conf/
RUN rm-fr/usr/local/wsop/console/logs
RUN ln-sf/wae/log/usr/local/wsop/console/logs
WORKDIR/usr/local/wsop/console/
CMD["/usr/local/bin/run.sh"]
根据示例4中的镜像构建脚本，执行镜像构建命令，可以实现一键式自动构建镜像。本发明实施例中，在执行构建镜像命令得到用于运行目标应用的镜像之前，还包括：根据与目标应用匹配的待输入参数确定用于运行目标应用的镜像的名称。一种可选的实施方式为，根据与目标应用匹配的待输入参数中的任多项确定镜像名称，举个例子，比如镜像名称命名由如下变量信息对应的待输入参数确定：
<docker-registry-url>/<namespace>/<app-name>:<version>；
其中，变量信息docker-registry-url为镜像中心地址，一般指的是域名，例如，其对应的待输入参数为registry.wae.haplat.net；变量信息namespace为命名空间，例如，其对应的待输入参数为wplus；变量信息app-name为应用名称，例如，其对应的待输入参数为wplus-console；变量信息version为应用版本号，例如，其对应的待输入参数为1.4.1-1；该例子中镜像的名称为：registry.wae.haplat.net/wplus/wplus-console:1.4.1-1./。
在生成镜像之后，即可将镜像推送到镜像仓库供后续验证及应用部署。所需使用到的命令如下：
查看镜像：docker images
推送镜像：docker push registry.wae.haplat.net/wplus/wplus-console:1.4.1-1。
为了更清楚的介绍上述方法流程，本发明实施例再提供一个示例。
图3示例性示出了本发明实施例提供的一种版本文件升级方法流程示意图，如图3所示，本发明实施例提供的一种版本文件升级方法，该方法包括以下步骤：
步骤301：获取目标应用所属的应用类型对应的模板文件；模板文件包括平台环境配置信息和至少一个变量信息；
步骤302：将至少一个变量信息显示在Web页面或目标应用的属性文件中；
步骤303：若监测到Web页面或目标应用的属性文件中存在数据输入，则获取每个变量信息和每个变量信息对应的输入的数据组成的至少一对键值对；每对键值对包括的关键字为变量信息，值为该变量信息对应的与目标应用匹配的待输入参数；
步骤304：将获取的至少一对键值对解析成待匹配结构体；所述模板文件中包括所述至少一个变量信息对应的预设结构体，待匹配结构体与预设结构体的格式一致；
步骤305：针对待匹配结构体中的每个变量信息，将待匹配结构体中的该变量信息与预设结构体中的每个变量信息进行匹配；
步骤306：从预设结构体中确定出与待匹配结构体中的该变量信息一致的变量信息；
步骤307：将预设结构体中确定出的与待匹配结构体中的该变量信息一致的变量信息对应的位置确定为目标位置；
步骤308：将目标位置处的变量信息删除，并将待匹配结构体中变量信息对应的与目标应用匹配的待输入参数填充至目标位置，得到镜像构建脚本；
步骤309：根据镜像构建脚本执行构建镜像命令，得到用于运行目标应用的镜像。
通过上述实施例可以看出，本发明实施例中，获取目标应用所属的应用类型对应的模板文件；模板文件包括平台环境的配置信息和至少一个变量信息；获取至少一个变量信息对应的与目标应用匹配的待输入参数；根据平台环境配置信息、至少一个变量信息和至少一个变量信息对应的与目标应用匹配的待输入参数，执行构建镜像命令得到用于运行目标应用的镜像。如此，开发或运维人员只需要知道至少一个变量信息对应的与目标应用匹配的待输入参数，就可 以实现自动构建运行目标应用类型的镜像，开发或运维人员无需学习镜像构建技术，可以减少学习成本。
