ol-concourse-lib
A Python DSL for programmatically building Concourse CI/CD pipelines.
Instead of writing YAML files by hand, use typed Python classes to construct type-safe pipeline definitions that serialize to valid Concourse pipeline YAML.
Installation
pip install ol-concourse-lib
# or with Pulumi job builder support:
pip install "ol-concourse-lib[pulumi]"
Quick Start
from ol_concourse.lib.models.pipeline import Identifier
from ol_concourse.lib.resources import git_repo, registry_image
from ol_concourse.lib.resource_types import packer_build
from ol_concourse.lib.jobs.infrastructure import packer_jobs
import yaml, json
# Build a pipeline fragment for packer AMI builds
code = git_repo(
name=Identifier("packer-templates"),
uri="https://github.com/myorg/packer-templates",
branch="main",
)
fragment = packer_jobs(
dependencies=[],
image_code=code,
node_types=["web", "worker"],
)
pipeline = fragment.to_pipeline()
print(yaml.dump(json.loads(pipeline.model_dump_json())))

Regenerating Pipeline Models
models/pipeline.py is generated from the Concourse pipeline JSON schema:
pip install datamodel-code-generator
datamodel-codegen \
--url https://raw.githubusercontent.com/nicholasdille/concourse-jsonschema/main/concourse.json \
--output src/ol_concourse/lib/models/pipeline.py \
--output-model-type pydantic_v2.BaseModel
