Creating a pipeline specification

In the Creating a repository section, we created a repository called photos and put some test files in it. The pipeline specification for this example must reference the following elements:

• An input repository with data to process
• A computer program or a script that needs to run against your data
• A glob pattern that specifies the datum granularity
• A Docker image with built-in dependencies that contains your code

We have created a pipeline specification for you so that you can use it to create the pipeline. Here is what is in the pipeline specification file in the YAML Ain't Markup Language (YAML) format:

---
 pipeline:
   name: contour
 description: A pipeline that identifies contours on an image.
 transform:
   cmd:
   - python3
   - "/contour.py"
   image: svekars/contour-histogram:1.0
input:
   pfs:
