DigitalDownConverter — Deployment

Debian Packages

The pipeline is distributed as Debian packages built by CI and hosted in the MPIFR Aptly repository. The edd_dbbc Docker image installs them at build time.

Package	Contents
`python3-edd-dbbc`	Python library (`edd.dbbc`)
`edd-dbbc-utils`	Compiled C++ binaries (`ddc_processing`, etc.)

Docker Image

Property	Value
Image name	`edd_dbbc`
Base image	`edd_build:cuda12.6.1_ubuntu24.04`
Ansible build role	`roles/edd_dbbc/`
Registry	`gitlab-registry.mpcdf.mpg.de/mpifr-bdg/edd/dbbc`

The image installs python3-edd-core, python3-edd-dbbc, edd-dbbc-utils, mkrecv, mksend, and psrdadacpp from the MPIFR Aptly repository.

CI Pipeline

Stage	Job	Description
`build`	`build_source`	CMake + make, produces `release/` artifacts
`build`	`build-deb`	Builds Debian packages via `.build_template`
`test`	`test_cpp`	CTest suite against built binaries
`test`	`test_python`	Python test suite with coverage
`stats`	`coverage_cpp`	lcov C++ coverage badge
`stats`	`coverage_python`	Python coverage badge
`stats`	`cpplint`	C++ style lint badge
`stats`	`pylint`	Python lint
`deploy`	`upload-deb`	Uploads packages to Aptly (requires build + tests)
`deploy`	`build_docker`	Builds and pushes `edd_dbbc` image

Ansible Deployment

The pipeline is deployed via the ddc_processor Ansible role:

ansible-playbook provision.yml --tags ddc_processor

The role delegates to EDD.core.common with:

image_name: edd_dbbc
default_container_name: ddc_processor
container_cmd: "edd_ddc_processor --host={{ edd_subnet }} --port={{ bind_port }}"
register_as_pipeline: True
provision_test_imports: "edd.dbbc.ddc_processor_tests"

Provision Tests

Provision tests are imported from edd.dbbc.ddc_processor_tests. They verify that the pipeline starts, accepts configuration, and reaches the configured state before the observation begins.
