Question

我正在使用docker运行一个小的tesseract API。 ruby应用程序调用命令行在图像上使用tesseract。在此之前，它首先使用脚本预处理图像：

post '/extractText' do
  begin
    bas64Image = Base64.decode64(params[:image])
    imageFile = Tempfile.new(['image', '.jpg'])
    imageFile.write(bas64Image)
    imageFile.close
    `textcleaner #{imageFile.path} #{imageFile.path}`
    output = `tesseract #{imageFile.path} --psm 6 stdout`
    p output
  rescue
    status 402
    return "Error reading image"
  end
  status 200
  return output.to_json
end

该应用程序忽略了当前行textcleaner #{imageFile.path} #{imageFile.path}，因为它什么都不做。

在命令行中使用类似docker run tess textcleaner receipt3.jpg receipt3.jpg的内容进行测试时出现以下错误：

container_linux.go:265: starting container process caused "exec: \"textcleaner\": executable file not found in $PATH"
docker: Error response from daemon: oci runtime error: container_linux.go:265: starting container process caused "exec: \"textcleaner\": executable file not found in $PATH".
ERRO[0000] error waiting for container: context canceled

FROM tesseractshadow/tesseract4re

RUN apt-get update && apt-get install -y build-essential ruby-full libffi-dev libgmp3-dev ruby-dev

WORKDIR /home/work

RUN gem install bundler

COPY Gemfile .
COPY textcleaner /home/work
RUN chmod +x /home/work/textcleaner

RUN bundle install

COPY . /home/work

EXPOSE 8080

CMD bundle exec ruby app.rb

我不知道如何将文件添加到$ PATH。当我这样做时：

COPY textcleaner $PATH
RUN chmod +x $PATH/textcleaner

我得到了

chmod: cannot access '/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin/textcleaner': Not a directory
The command '/bin/sh -c chmod +x $PATH/textcleaner' returned a non-zero code: 1

在第二行。

任何帮助将不胜感激

在你的Docker文件中你应该有这一行：

ENV PATH /path/to/your/textcleaner:$PATH

Docker无法运行$ PATH＆＃34;中找不到的脚本可执行文件
