Question

我想创建一个构建器图像app_name:latest，它将采用多个源输入，例如另一个图像和二进制源，然后将输出创建为app_name:latest。

    "apiVersion": "v1",

        "name": "app_name",
        "labels": {

                }
            },
            {

                "github": {
                    "secret": "secret"
                }
            },
            {
                "type": "ImageChange",
                "imageChange": {}
            }
        ]
    }
}

您可以使用所谓的链式构建。

使用oc new-build创建图像时，请使用以下选项：

--source-image='': Specify an image to use as source for the build. You must also specify --source-image-path.
--source-image-path='': Specify the file or directory to copy from the source image and its destination in the build directory. Format:

--source-image的参数是从单独的构建创建的现有图像流的名称。这可能包含其他预编译的工件或数据文件。

--source-image-path的参数是从中复制文件的图像中的绝对参数，以及源构建注入的上载文件目录中的相对路径名，其中应放置单独图像中的文件。后者不能是绝对路径，因此您必须覆盖assemble脚本才能将其移动到正确的位置。

就原始构建配置中的情况而言，它是：

    "source": {
        "git": {
            "ref": "master",
            "uri": "https://github.com/jakevdp/PythonDataScienceHandbook"
        },
        "images": [
            {
                "from": {
                    "kind": "ImageStreamTag",
                    "name": "packages-python-27:latest"
                },
                "paths": [
                    {
                        "destinationDir": ".s2i",
                        "sourcePath": "/opt/app-root/packages"
                    }
                ]
            },
            {
                "from": {
                    "kind": "ImageStreamTag",
                    "name": "packages-python-35-wheelhouse:latest"
                },
                "paths": [
                    {
                        "destinationDir": ".s2i",
                        "sourcePath": "/opt/app-root/packages"
                    }
                ]
            },
            ...
    },
},

直接添加到原始构建配置时，您可以拥有多个图像源。命令行只允许设置一个。
