$ notebook-pge-wrapper create <project_name>

The following project structure will be generated

.
├── Dockerfile.template

└── submit_job.ipynb

• Dockerfile will go through container-builder to build the docker image
  • Will later be used to execute the notebook in a PGE setting
• Place all your .ipynb files in notebook_pges/

The notebook-pge-wrapper dockerfile command will read in values from settings.yml and fill in the values in Dockerfile.template

To use a new docker image edit the base_image value in settings.yml

base_image: artifactory.com/nisar_ade:r1.3
user: jovyan

To update the Dockerfile with a new base_image run this command in the root directory of your project

$ notebook-pge-wrapper dockerfile

Your notebooks will leverage papermill to execute notebooks

• Papermill Project
• Papermill parameters documentation
• Can set parameter types 2 ways
  • Adding a comment, ie. x = 34 # type: int
  • Python type hinting (introduced in python 3.5)

requirements.ipynb is used to install additional dependencies in the docker image

It's separated into 3 sections:

• CentOS installation (sudo yum install <package> -y)
• Conda installtion (sudo conda install <package> -y)
• Python library installation (sudo pip install <package>)

• Tag the top notebook cell with parameters
  • To add tags in your notebook, go to the toolbar: View -> Cell Toolbar -> Tags
• prepend any hysds specification fields with _ and extract_hysds_specs will populate hysds-io and job_specs with it's specified values
  • If not found it will set to default values (ie. time_limit: 3600)

# job_specs
_time_limit -> time_limit
_soft_time_limit -> soft_time_limit
_disk_usage -> disk_usage
_required_queue -> required_queue

# hysds-ios
_submission_type -> submission_type
_label -> label

Example:

# parameters
from typing import List

a = 100 # type: int
b = "jfksl" # type: str
c = 10.2553 # type: float
d = [1,2,3,4,5] # type: List
e: List[str] = ['a', 'b', 'c']
f = "fjskl"
g: List[str] = ["a", "b", "c"]

# hysds specs
_time_limit = 57389
_soft_time_limit = 4738
_disk_usage = "10GB"
_submission_type = "iteration"
_required_queue = "test_queue-worker"
_label = "TEST LABEL FOR HYSDS_IOS"

Use the notebook-pge-wrapper cli to generate the spec files

• notebook-pge-wrapper specs all to iterate generate spec files for all notebooks in notebook_pges/
• notebook-pge-wrapper specs <notebook path> to generate spec files for a notebook

$ notebook-pge-wrapper specs --help
Usage: notebook-pge-wrapper specs [OPTIONS] NOTEBOOK_PATH

  Generates the hysdsio and job specs for json files (in the docker
  directory) for a notebook

  enter "all" to generate all spec files in notebook_pges/

  ie. notebook-pge-wrapper specs <notebook_path or all>

Options:
  -s, --settings TEXT  (optional) path to settings.yml, will default to
                       ~/.config/notebook-pge-wrapper/settings.yml if not
                       supplied

  --help               Show this message and exit.
