Add publisher output path contract by IEvangelist · Pull Request #18875 · microsoft/aspire

IEvangelist · 2026-07-23T18:57:16Z

Description

Custom pipeline publishers can currently write only through the primary --output-path contract. Publishers that also generate repository artifacts such as .configgen/ and .pipelines/ must discover roots themselves, and the CLI cannot safely inventory or relocate those writes for drift verification.

This change adds an experimental publisher output contract rooted at the AppHost project directory. Pipeline steps can declare named file or directory outputs, resolve the authoritative writable path at execution time, and use a separate logical target path when generated content refers to its checked-in destination.

User-facing usage

var inventoryDefinition = new PipelineOutputDefinition(
    "inventory",
    ".configgen",
    PipelineOutputKind.Directory);

var step = new PipelineStep
{
    Name = "generate-inventory",
    Outputs = [inventoryDefinition],
    SupportsOutputPathRelocation = true,
    Action = context =>
    {
        var inventory = context.Outputs.Resolve(inventoryDefinition);
        Directory.CreateDirectory(inventory.OutputPath);
        File.WriteAllText(
            Path.Combine(inventory.OutputPath, "inventory.txt"),
            inventory.LogicalTargetPath);
        return Task.CompletedTask;
    }
};

builder.Pipeline.AddStep(step);

context.Outputs.AppHostDirectory provides the authoritative AppHost root. Named targets can be overridden with Pipeline:Outputs:<step-name>:<output-name>:Path.

The runtime now freezes the selected step graph and output plan before BeforePublishEvent, exposes that plan through the versioned pipeline-outputs.v1 main-backchannel capability, and pauses relocated execution until the CLI explicitly authorizes it. Non-relocatable selected steps fail closed at authorization. Built-in manifest, Docker Compose, Kubernetes, Azure, Radius, EF Core, and JavaScript publishing steps now use or opt into this contract.

This is the output-contract prerequisite for aspire publish --verify in #18833; the CLI drift reconciliation is intentionally a follow-up.

Validation

Full repository build with native compilation skipped.
27 focused Hosting output-plan and backchannel contract tests.
26 CLI backchannel serializer and publish integration tests.
Targeted Docker, Kubernetes, Azure, EF Core, JavaScript, and Radius publisher tests.

Fixes #18873

Test Scenarios Executed

Scenario 1: Exact-head artifact and focused source validation

Objective: Verify the tested dogfood artifact matches the PR and exercise the output plan, relocation authorization, backchannel contract, and CLI serialization directly from the same commit.

Coverage Type: Artifact identity, unit, and integration

Status: PASS

Steps:

Installed PR Add publisher output path contract #18875 through the official dogfood PowerShell installer into an isolated path.
Verified the installed binary reported 13.5.0-pr.18875.g098cb9e1.
Restored the exact-head source checkout.
Ran PipelineOutputRegistryTests and BackchannelContractTests.
Ran PipelineOutputPlan_RoundTripsThroughSerializer.

Results:

Hosting tests: 27 passed, 0 failed, 0 skipped.
CLI serializer test: 1 passed, 0 failed, 0 skipped.
The authorization tests confirmed relocated execution pauses before BeforePublishEvent and pipeline actions, then resumes only after authorization.

Evidence:

install-and-version.log
hosting-focused-tests.log
cli-focused-tests.log

Scenario 2: Custom directory and file outputs

Objective: Verify a custom publisher can declare both output kinds and write through the resolved paths rooted at the AppHost directory.

Coverage Type: Happy path

Status: PASS

Steps:

Created a fresh aspire-empty project from the PR hive.
Added a generate-repository-artifacts step required by publish.
Declared .configgen as a directory output and .pipelines/pipeline.json as a file output.
Published with the PR CLI.
Verified both artifacts existed and contained their fully resolved logical target paths.

Results:

.configgen/inventory.txt was written through the resolved directory output.
.pipelines/pipeline.json was written through the resolved file output.
Both logical target values matched their AppHost-rooted paths.

Evidence:

custom-outputs-publish.log
custom-outputs-evidence.log
Generated inventory.txt and pipeline.json

Scenario 3: Configured named-output override

Objective: Verify Pipeline:Outputs:<step>:<output>:Path overrides the default target without writing to the default path.

Coverage Type: Boundary/configuration

Status: PASS

Steps:

Created a fresh aspire-empty project from the PR hive.
Declared a default .configgen directory output.
Set Pipeline__Outputs__generate-override-artifact__inventory__Path=overrides\inventory.
Published with the PR CLI.
Verified the artifact was written under overrides\inventory, its logical target matched the override, and .configgen remained absent.

Evidence:

override-output-publish.log
override-output-evidence.log
Generated override inventory.txt

Scenario 4: Built-in manifest and Docker Compose publishers

Objective: Verify built-in publishers use the new primary output resolver without regressing file-vs-directory output behavior.

Coverage Type: Happy path and boundary

Status: PASS

Steps:

Created separate fresh apps for directory-form and JSON-file-form manifest output.
Ran aspire do publish-manifest with a directory output and verified aspire-manifest.json was created beneath it.
Ran aspire do publish-manifest with an explicit .json output and verified that exact file was created.
Created another fresh app, added Aspire.Hosting.Docker version 13.5.0-pr.18875.g098cb9e1, a Redis container, and a Docker Compose environment.
Published and verified docker-compose.yaml contained the expected cache service and redis:7.4-alpine image.

Results:

Both manifest shapes produced valid JSON at the expected location.
Docker Compose publishing completed successfully and wrote through the configured primary output directory.

Evidence:

manifest-directory-publish.log
manifest-directory-evidence.log
manifest-file-publish.log
manifest-file-evidence.log
docker-publisher-publish.log
docker-publisher-evidence.log
Generated manifests and docker-compose.yaml

Scenario 5: Fail-closed output validation

Objective: Verify invalid output plans fail during preparation before publisher actions write artifacts.

Coverage Type: Unhappy path

Status: PASS

Cases:

Overlapping targets: Declared .configgen and .configgen/nested. Publish exited with code 6, reported overlapping target paths, and did not create the action marker.
Wrong target kind: Declared .configgen as a file after creating it as a directory. Publish exited with code 6, reported the file/directory mismatch, and did not create the action marker.

Expected Unhappy-Path Outcome: A non-zero exit, a specific validation error, and no pipeline-action writes.

Evidence:

overlap-outputs-publish.log
overlap-outputs-evidence.log
wrong-kind-publish.log
wrong-kind-evidence.log

Summary

Scenario	Status	Notes
Exact-head artifact and focused tests	PASS	28 tests passed
Custom directory and file outputs	PASS	Both output kinds resolved and wrote correctly
Configured named-output override	PASS	Override won; default target untouched
Manifest and Docker Compose publishers	PASS	Directory/file manifest semantics and Compose output verified
Fail-closed validation	PASS	Both invalid plans failed before action writes

Overall Result

PASS - PR VERIFIED IN THE APPROVED TEST SCOPE

No product defects were found. The relocation-only backchannel flow is not yet exposed as a CLI verification command in this PR, so its pause, inspection, authorization, and relocated-write behavior was validated through the exact-head Hosting integration tests.
