我在使用云效自定义构建环境的遇到镜象安装的命令找不到的问题，请各位使用过的大神指点下，以下是我的release文件,markdown的样式有些问题，请大家选择文字方可看见。

# 请参考 https://help.aliyun.com/document_detail/59293.html 了解更多关于release文件的编写方式 

code.language = scripts

# 构建镜像地址
build.image=registry.cn-shenzhen.aliyuncs.com/kstudio/utils-docker@sha256:681a2864052e3f68ee898be72d59358f08c95b23187d652c92330920d769d121

build.command=sh aliyun-deploy.sh

在自定义的镜像kstudio/utils-docker中已经安装了docker命令，并在release文件中按要求预值了镜像地址在build.image中，但进行构建的时候环境找不到docker命令，我猜是根本没有应用上自定义的构建环境，请各位指教一下用法，docker只是一个例子，测试过svn,git,ftp等自己安装的命令全部都不行。

以下是构建输出的日志
