CWL User Guide 15: Staging Input Files

Common Workflow Language User Guide: Staging Input Files

今回は、実行時に必要なファイルをステージングする方法、について書かれています

この回にでてくる主なキーワード

CWLファイル、linkfile.cwl

linkfile.cwl

#!/usr/bin/env cwl-runner

cwlVersion: v1.0
class: CommandLineTool
hints:
  DockerRequirement:
    dockerPull: java:7
baseCommand: javac

requirements:
  - class: InlineJavascriptRequirement
  - class: InitialWorkDirRequirement
    listing:
      - $(inputs.src)

inputs:
  src:
    type: File
    inputBinding:
      position: 1
      valueFrom: $(self.basename)

outputs:
  classfile:
    type: File
    outputBinding:
      glob: "*.class"

パラメータファイルarguments-job.yml

arguments-job.yml

src:
  class: File
  path: Hello.java

必要なファイル

第８回で作った Hello.java が必要になります

public class Hello {}

実行

実行方法

cwltool linkfile.cwl arguments-job.yml

実行結果

$ cwltool linkfile.cwl arguments-job.yml

    }
}
Final process status is success

実行結果確認

Hello.class ができていることが確認できます

$ ls
arguments-job.yml  Hello.class  Hello.java  linkfile.cwl
