dkist-processing-test

Overview

The dkist-processing-test library serves as an example implementation of a Tasks and Workflows using the dkist-processing-core framework and dkist-processing-common Tasks.

The recommended project structure is to separate tasks and workflows into separate packages.

Build

Artifacts are built through bitbucket pipelines

The pipeline can be used in other repos with a modification of the package and artifact locations to use the names relevant to the target repo.

e.g. dkist-processing-test -> dkist-processing-vbi and dkist_processing_test -> dkist_processing_vbi

Deployment

Deployment is done with turtlebot and follows the process detailed in dkist-processing-core

Development

git clone git@bitbucket.org:dkistdc/dkist-processing-test.git
cd dkist-processing-test
pre-commit install
pip install -e .[test]
pytest -v --cov dkist_processing_test

Deployment

When a new release is ready to be built the following steps need to be taken:

1. Freezing Dependencies

A new “frozen” extra is generated by the dkist-dev-tools package. If you don’t have dkist-dev-tools installed please follow the directions from that repo.

To freeze dependencies run

ddt freeze vX.Y.Z[rcK]

Where “vX.Y.Z[rcK]” is the version about to be released.

2. Tag and Push

Once all commits are in place add a git tag that will define the released version, then push the tags up to Bitbucket:

git tag vX.Y.Z[rcK]
git push --tags origin BRANCH

In the case of an rc, BRANCH will likely be your development branch. For full releases BRANCH should be “main”.
