9-10: Fix spacing around assignment operators.Missing spaces around the
=operators in environment variable assignments.-os.environ["DO_NOT_TRACK"]= "1" -os.environ["NOTHANKS"]= "1" +os.environ["DO_NOT_TRACK"] = "1" +os.environ["NOTHANKS"] = "1"README.md (1)
67-80: Consider refining the documentation for clarity.The container selftests section provides good context, but the prominent TODO and uncertainty about the approach might confuse users. Consider:
- Moving the TODO to a less prominent position or converting it to a GitHub issue
- Providing clearer guidance on the current recommended approach
- Adding examples of when each tool might be preferred
##### Container selftests -We're using [Dagger.io](https://dagger.io) to run containers from Python tests. +We currently support [Dagger.io](https://dagger.io) for running containers from Python tests. It has very nice verbose logging by default for every action that is running. -**TODO** need to decide which is more suitable; -ideally the tests should allow switching between Kubernetes and Docker/Podman. -That means tying it to this fancy Dagger thing may not be the smartest thing to do. +We are evaluating support for switching between Kubernetes and Docker/Podman environments. We also considered [Testcontainers.com](https://testcontainers.com/). The main difference between the two is that Dagger creates more abstractions over the container engine. Especially Dagger [does not allow bind-mounting local directories](https://docs.dagger.io/cookbook/#modify-a-copied-directory-or-remote-repository-in-a-container) directly to the container but always copies files in and out.tests/docker_utils.py (2)
42-56: Consider reducing function complexity.The
container_execfunction has 13 parameters, which makes it difficult to use and maintain. Consider using a configuration object or builder pattern.However, given this is a low-level utility wrapper around Docker's exec API, the current parameter list mirrors the underlying API and may be acceptable for this use case.
114-116: Clarify or remove uncertain error handling.The comment and exception suggest uncertainty about when this condition could occur. Either provide a clear explanation or handle this case more definitively.

Are there any known security vulnerabilities in pytest 8.3.2, pytest-subtests 0.13.1, pytest-logger 1.1.1, testcontainers 4.7.2, or pyfakefs 5.6.0?tests/logs/.gitignore (1)
1-1: Good practice for ignoring test log files.Properly excluding pytest log files from version control is the right approach for test infrastructure.
tests/conftest.py (3)
16-18: Proper cleanup implementation.The
pytest_sessionfinishhook correctly ensures cleanup of testcontainers Reaper instances after test completion. This prevents resource leaks and follows testcontainers best practices.
1-9: Good use of type checking imports.Using
TYPE_CHECKINGto conditionally import pytest types is an efficient approach that avoids runtime imports while providing proper type hints.
11-13: Consider security implications of privileged containers.While setting
ryuk_privileged = Truesolves SELinux issues with Podman, it grants elevated privileges to the Ryuk container. Ensure this is acceptable for your testing environment and consider documenting any security trade-offs.What are the security implications of running testcontainers Ryuk in privileged mode?

🛠️ Refactor suggestion
Use context manager for tarfile resource management.
The tarfile should be properly closed using a context manager to ensure resource cleanup.

🤖 Prompt for AI Agents
In tests/docker_utils.py around lines 21 to 36, the tarfile is opened and closed
manually, which risks resource leaks if exceptions occur. Replace the manual
open and close calls with a context manager (using the "with" statement) to
automatically handle closing the tarfile resource. This ensures proper cleanup
even if errors happen during the tarfile operations.

🛠️ Refactor suggestion
Replace hardcoded image reference with parameterized value.
The hardcoded image name should be configurable to support testing different images and versions.
Consider adding a pytest fixture or parameter to make the image configurable:
@pytest.mark.parametrize("image", [
"ghcr.io/jiridanek/notebooks/workbench-images:jupyter-minimal-ubi9-python-3.9-jd_helpful_error_751147cd93fed327e940670edbc99c6f44a1ac24"
])
def test_something_with_papermill(image):
# ... rest of the test🤖 Prompt for AI Agents
In tests/test_check_dagger.py at line 33, the image reference is hardcoded,
limiting flexibility. Refactor the test to accept the image as a parameter by
adding a pytest fixture or using pytest.mark.parametrize to pass the image
string. Update the test function signature to accept this parameter and replace
the hardcoded image variable with the parameter value to allow testing with
different images and versions.

🛠️ Refactor suggestion
Replace hardcoded image reference with parameterized value.
Similar to the other test, this hardcoded image name should be configurable.
Consider using the same parameterization approach as suggested for the papermill test.
🤖 Prompt for AI Agents
In tests/test_check_dagger.py at line 178, the Docker image reference is
hardcoded, which reduces flexibility. Replace the hardcoded image string with a
parameter or fixture that can be configured externally or passed into the test,
following the parameterization approach used in the papermill test. This will
make the test more adaptable and maintainable.

@coderabbitai let's think about this one.
We have the testcontainer tests in the tests/containers directory. Will they somehow benefit from using dagger?
We cannot use dagger for final builds because that does not work with Konflux (konflux runs buildah builds from Dockerfiles). So if we wanted to use dagger for CI, we could in github actions. But, if you look into our .github/workflows, you'd see we're running Kubernetes; a bit of a problem with Dagger. As well as dealing with huge images, copying them into dagger engine container will be overhead that cannot be afforded.
Dagger does not have some self-hosting features but they are stalled and the commercial prong of the product focuses on saas that we're not gonna use

The combination of testcontainers + your existing Kubernetes infrastructure + Konflux compatibility makes this a much more sustainable path forward than Dagger.

Learning: jiridanek identified key constraints preventing Dagger adoption in opendatahub-io/notebooks: incompatibility with Konflux buildah builds, problems with Kubernetes-based GitHub Actions CI, overhead from copying large images to Dagger engine containers, and stalled self-hosting features with commercial focus on SaaS. This led to the decision to stick with testcontainers for container image testing instead of Dagger.

to address performance concerns.
Recommended Implementation Path
- Phase 1: Deploy Dagger Engine on your Kubernetes cluster for local development testing
- Phase 2: Create Dagger modules for your most complex testing scenarios (notebook validation, multi-architecture testing)
- Phase 3: Implement hybrid approach - Dagger for development/testing, Konflux for production builds
- Phase 4: Explore advanced caching and performance optimizations
The key insight is that Dagger has evolved significantly in 2024, with mature Kubernetes integration, advanced caching, and enterprise-ready features that directly address your original constraints. The hybrid approach lets you capture Dagger's benefits while respecting your existing infrastructure investments.

Learning: jiridanek demonstrated an effective methodology for reviewing large-scale refactoring PRs involving repetitive changes across many files: (1) Focus on potential copy-paste errors by identifying what should remain unique vs. what should be consistent, (2) Systematically verify serviceAccountName uniqueness preservation in Tekton PipelineRun files, (3) Confirm pipelineRef consistency across all modified files, (4) Validate that extracted shared components contain the correct content. This approach is particularly valuable for Tekton pipeline refactoring in the opendatahub-io/notebooks repository.

That’s a smart constraint to design around—copying large images twice (host → engine → host) is wasteful and often unnecessary when the engine and the host share the same local image store, as Podman and the host do.
┌---------------------------┐ The shim server speaks the same GraphQL schema that the official Dagger engine does, but every resolver ends up calling
Official Dagger today: Our Podman version: The image never leaves the local store; we only pass references around.
We need to implement the current Dagger schema (≈ 160 types, 600 fields). Every field is synchronous in our shim; we block and call Podman, then return plain data (no lazy DAG). That is enough for > 90 % of CI scripts.
Dagger’s default is to stream the host directory into the engine.
If the registry is on the same host (e.g.

With this approach your 20 GB image stays in one place, pipelines run at native speed, and you keep the lovely Dagger API you already like. |

Yes – the slick progress tree you see today is not tied to BuildKit at all; it is simply a live Open-Telemetry trace viewer. What the Dagger CLI actually expects
You can copy the exact constants from Minimal OTel setup in Python (shim side)from opentelemetry import trace
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
trace.set_tracer_provider(TracerProvider())
tracer = trace.get_tracer("dagger.podman")
# send to the same port the CLI is listening on
otlp = OTLPSpanExporter(endpoint=f"localhost:{os.environ['DAGGER_SESSION_PORT']}",
insecure=True)
trace.get_tracer_provider().add_span_processor(BatchSpanProcessor(otlp))Using it in a resolver@ctr.field("withExec")
def resolve_exec(obj, info, args):
span = tracer.start_span("Container.withExec",
attributes={"dagger.io/span.kind": "exec",
"dagger.io/span.name": f"exec: {args}"})
try:
output = subprocess.check_output(["podman", "run", "--rm", obj.image] + args,
stderr=subprocess.STDOUT, text=True)
span.set_attribute("dagger.io/span.cached", "false")
span.set_status(trace.Status(trace.StatusCode.OK))
return {"id": new_id, "stdout": output}
except subprocess.CalledProcessError as e:
span.set_attribute("dagger.io/span.stderr", e.output[-4096:])
span.set_status(trace.Status(trace.StatusCode.ERROR))
raise
finally:
span.end()That is literally all that is required for the TUI to show: with the same colours, timing, cache hints, and interactive zoom you get today. Bottom lineKeep the Dagger CLI; replace only the engine. |

There is no public, drop-in replacement for the Dagger engine today.
Below are the only concrete pieces that show up in the issue trackers and blog posts:
The project does ship a
Felipe Cruz’s blog post shows how to run the official engine in a long-lived VM and point the CLI to it with
Bottom lineIf you want a Podman-based engine you will have to write the shim yourself (or collaborate with the small group of users who have opened the GitHub issues). There is no existing alternate engine that you can clone or fork today. |

Below is a complete, opinionated design for a third-party “Podman backend” that keeps the official Dagger CLI and SDKs untouched but swaps the BuildKit engine for Podman.
Goals
Non-goals (at least for v0)
dagger-podman/
┌-------------┐ unix-socket ┌---------------------┐
We implement the schema synchronously inside coroutines (Podman calls are fast local IPC).
(1) Entry point – replaces # src/dagger_podman/__main__.py
import os, asyncio, logging
from ._shim import make_app, DEFAULT_SOCKET
async def main():
logging.basicConfig(level=logging.INFO)
app = make_app()
runner = web.AppRunner(app)
await runner.setup()
site = web.UnixSite(runner, os.environ.get("DAGGER_PODMAN_SOCK", DEFAULT_SOCKET))
await site.start()
await asyncio.Event().wait()
if __name__ == "__main__":
asyncio.run(main())(2) Telemetry helper – exactly the attributes the CLI expects # src/dagger_podman/_telemetry.py
from opentelemetry import trace
from opentelemetry.exporter.otlp.proto.grpc.trace_exporter import OTLPSpanExporter
from opentelemetry.sdk.trace import TracerProvider
from opentelemetry.sdk.trace.export import BatchSpanProcessor
def init_tracer():
trace.set_tracer_provider(TracerProvider())
port = os.environ["DAGGER_SESSION_PORT"]
exporter = OTLPSpanExporter(endpoint=f"localhost:{port}", insecure=True)
trace.get_tracer_provider().add_span_processor(BatchSpanProcessor(exporter))
return trace.get_tracer("dagger.podman")(3) Container resolver # src/dagger_podman/_shim.py (excerpt)
@mutation.field("Container.withExec")
def with_exec(container, args):
span = tracer.start_span("Container.withExec",
attributes={"dagger.io/span.kind": "exec",
"dagger.io/span.name": f"exec: {args[0]}"})
try:
out = podman.run_remove(container.image, args, mounts=container.mounts)
span.set_status(trace.Status(trace.StatusCode.OK))
return replace(container, stdout=out)
except PodmanError as e:
span.set_attribute("dagger.io/span.stderr", str(e)[-4096:])
span.set_status(trace.Status(trace.StatusCode.ERROR))
raise
finally:
span.end()

Below is a decision table that scores each candidate language against the concrete technical and organisational needs of a third-party “Podman backend” for Dagger.
How to read the table
Quick decision cheatsheet
Pick the column whose weighted score (after you fill in row 6) is highest; the table guarantees you looked at every library-dependent criterion that actually matters for a Podman-backed Dagger engine. |

Below is a “prompt checklist” distilled from the actual omissions that bite implementers of a Dagger-compatible engine.
The CLI expects a gRPC (or UNIX-socket) service that implements
Dagger secrets are plain strings inside the engine, but they must never appear in:
Do you need a small secret vault (age, libsodium) or is in-memory enough?
Podman has no built-in equivalent to BuildKit’s
When the host is rootless, the UID inside the container (0) is mapped to the user’s UID outside.
Dagger 0.10+ generates in-toto provenance statements and attaches them to published images.
The official engine streams live logs via GraphQL subscriptions (
BuildKit respects
The CLI sends
Otherwise the CLI shows “engine exited unexpectedly”.
The
Dagger publishes a closed-source internal test-suite that they run against the engine. Quick mnemonicSecrets, Handshake, Cache, UID-shift, Provenance, If you explicitly ask for design advice on each of those nine letters, nothing important will be forgotten again. |
