This trades parallelism for correctness on under-analyzed inputs. +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) New `infra.layers[].dependsOn` field in `azure.yaml` lets authors declare hook-mediated edges (for example, when a postprovision hook in another layer writes an env var that this layer's bicepparam reads at provision time) that no static analyzer can infer from `.bicep` / `.bicepparam` / `.parameters.json` contents alone. Explicit edges union with detected edges and are validated for unknown layer names, self-references, and cycles. +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) Add `provision.layer.*` telemetry attributes (`count`, `max_parallel`, `safe_fallback_count`, `explicit_dependson_count`) on the ambient command span for multi-layer `azd provision` / `azd up` runs so the team can measure adoption and detect when the safe-by-default detector fallback engages on real templates. + ### Breaking Changes ### Bugs Fixed +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) Fix `concurrent map writes` panics when running `azd up` or `azd deploy` against multi-service projects: `*environment.Environment` now serializes all `dotenv` map access with an internal `sync.RWMutex`, the environment manager serializes `Save`/`Reload` calls, the singleton `kubectl.Cli` and `kustomize.Cli` are concurrency-safe, and AKS service publish/deploy updates to `SERVICE__IMAGE_NAME`/`ENDPOINT_URL` are wrapped in a package-level mutex (mirroring the Container Apps pattern). +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) Restore intra-phase progress detail (e.g. `"Pushing image"`, `"Updating container app"`) in the per-service progress tracker during `azd deploy` and `azd up`. The graph-driven engine previously dropped sub-phase `ServiceProgress.Message` updates, leaving the tracker's "Detail" column blank between phase transitions. +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) Make `x-ms-client-request-id` unique per HTTP request (previously derived from the shared OpenTelemetry trace id, which duplicated the header across every call in a single `azd` invocation). The Azure ARM common-types spec requires this header to be unique per request so Azure services can use it as a deduplication / idempotency / log-correlation key for individual calls — a shared value broke that contract and could cause collisions in parallel deploy / provision scheduling. Microsoft Graph's `client-request-id` header now uses the same per-request UUID for the same reason. +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) Fix cross-service image contamination when publishing multiple Container Apps in parallel via ACR remote build (`docker.remoteBuild: true`). ACR's `GetBuildSourceUploadURL` derives the relative blob path it hands back (`tasks-source//.tar.gz`) from the caller's `x-ms-correlation-request-id` header, and azd was sending the same correlation id — the root OpenTelemetry trace id shared across every request in a command — on every parallel upload. Each upload overwrote the previous service's source tarball before either build consumed it, so every Container App ended up running the last-uploaded service's image content under its own repository name. ACR source uploads now override `x-ms-correlation-request-id` with a freshly generated UUID per HTTP request so each parallel upload lands in a distinct blob. + ### Other Changes +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) **Security:** environment `.env` files are now persisted with mode `0600` (owner read/write only) on Unix-like systems. Previously they inherited the process umask (typically `0644`). The change tightens default permissions for files that may contain subscription IDs and values written via `azd env set`. +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) `azd up` now emits a single `"Provisioning and deploying (azd up)"` title and consolidated final message instead of the legacy `"Packaging services (azd package)"` / `"Provisioning Azure resources (azd provision)"` / `"Deploying services (azd deploy)"` banners and the `"Your up workflow to provision and deploy to Azure completed in …"` footer. CI/automation that grep-matches the legacy strings on stdout will need to update its expected output. +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) `azd up` honors `AZD_DEPLOY_CONCURRENCY` as a fallback when `AZD_UP_CONCURRENCY` is unset, so existing deploy-tuning configurations carry over to the unified up workflow. +- [[#7776]](https://github.com/Azure/azure-dev/pull/7776) `FailFast` semantics in the parallel scheduler: when a step fails, the scheduler cancels the run context to interrupt in-flight work, but steps that don't honor context cancellation (e.g., long-running ARM operations) will run to completion before the run returns. This is a behavior change versus the previous strictly-sequential `azd up`, which never started a later step after a prior failure. + ## 1.24.3 (2026-05-01) ### Features Added diff --git a/cli/azd/cmd/actions_coverage3_test.go b/cli/azd/cmd/actions_coverage3_test.go index 6d982c109ff..dd698726075 100644 --- a/cli/azd/cmd/actions_coverage3_test.go +++ b/cli/azd/cmd/actions_coverage3_test.go @@ -74,7 +74,7 @@ func Test_NewUpAction_Constructor(t *testing.T) { t.Parallel() flags := &upFlags{} console := mockinput.NewMockConsole() - a := newUpAction(flags, console, nil, nil, nil, nil, nil, nil, nil) + a := newUpAction(flags, console, nil, nil, nil, nil, nil, nil, nil, nil) ua := a.(*upAction) require.Same(t, flags, ua.flags) } diff --git a/cli/azd/cmd/container.go b/cli/azd/cmd/container.go index cc8f3da70aa..d62049ea65f 100644 --- a/cli/azd/cmd/container.go +++ b/cli/azd/cmd/container.go @@ -578,6 +578,11 @@ func registerCommonDependencies(container *ioc.NestedContainer) { container.MustRegisterScoped(project.NewImportManager) container.MustRegisterScoped(project.NewServiceManager) + // Unified up action: the exegraph-backed `azd up` entry point that + // collapses provision + package + publish + deploy (and project command + // hooks) into a single DAG. + container.MustRegisterScoped(cmd.NewUpGraphAction) + // Even though the service manager is scoped based on its use of environment we can still // register its internal cache as a singleton to ensure operation caching is consistent across all instances container.MustRegisterSingleton(func() project.ServiceOperationCache { diff --git a/cli/azd/cmd/up.go b/cli/azd/cmd/up.go index 8e6f8af922d..ab3345ef02e 100644 --- a/cli/azd/cmd/up.go +++ b/cli/azd/cmd/up.go @@ -31,11 +31,18 @@ type upFlags struct { cmd.DeployFlags global *internal.GlobalCommandOptions internal.EnvFlag + // flagSet is captured during Bind so the action can iterate the + // changed flag set when emitting synthetic cmd.package / cmd.provision + // telemetry spans (preserves nested cmd.* span shape from the legacy + // workflow runner that spawned `azd package` / `azd provision` as + // child processes — see UpGraphAction.Run). + flagSet *pflag.FlagSet } func (u *upFlags) Bind(local *pflag.FlagSet, global *internal.GlobalCommandOptions) { u.EnvFlag.Bind(local, global) u.global = global + u.flagSet = local u.ProvisionFlags.BindNonCommon(local, global) u.ProvisionFlags.SetCommon(&u.EnvFlag) @@ -67,15 +74,7 @@ type upAction struct { prompters prompt.Prompter importManager *project.ImportManager workflowRunner *workflow.Runner -} - -var defaultUpWorkflow = &workflow.Workflow{ - Name: "up", - Steps: []*workflow.Step{ - {AzdCommand: workflow.Command{Args: []string{"package", "--all"}}}, - {AzdCommand: workflow.Command{Args: []string{"provision"}}}, - {AzdCommand: workflow.Command{Args: []string{"deploy", "--all"}}}, - }, + upGraph *cmd.UpGraphAction } func newUpAction( @@ -88,6 +87,7 @@ func newUpAction( prompters prompt.Prompter, importManager *project.ImportManager, workflowRunner *workflow.Runner, + upGraph *cmd.UpGraphAction, ) actions.Action { return &upAction{ flags: flags, @@ -99,6 +99,7 @@ func newUpAction( prompters: prompters, importManager: importManager, workflowRunner: workflowRunner, + upGraph: upGraph, } } @@ -157,27 +158,36 @@ func (u *upAction) Run(ctx context.Context) (*actions.ActionResult, error) { startTime := time.Now() - upWorkflow, has := u.projectConfig.Workflows["up"] - if !has { - upWorkflow = defaultUpWorkflow - } else { + // User-authored custom `workflows.up:` in azure.yaml still delegates to + // the sequential workflow runner (spawning `azd package`, `azd provision`, + // `azd deploy` as sub-commands).

Precedence: `--timeout` CLI flag first, then `AZD_DEPLOY_TIMEOUT`, then the default. Invalid or non-positive values cause an immediate error. | + +No new environment variables are introduced at the graph engine layer — `pkg/exegraph` is +configuration-neutral. All three concurrency knobs live in the command layer and map to +the scheduler's `RunOptions.MaxConcurrency` field. + +## Known Limitations + +1. **Error policy** — All production paths use `FailFast`. `ContinueOnError` is + implemented in the scheduler but not exposed as a user option. + +2. **Custom workflows** — Projects defining a custom `workflows.up:` in `azure.yaml` + bypass the **unified cross-phase** DAG and run through `workflow.Runner` instead. + Each sub-command spawned by `workflow.Runner` (`azd provision`, `azd deploy`, + `azd package --all`) still executes its own phase-scoped DAG internally, so + parallel multi-layer provisioning and parallel service deploys are preserved. + What is lost is cross-phase fusion (packaging cannot overlap with provisioning) + and the synthetic `cmdhook-*` node integration. Projects using only project + command hooks (no custom workflow) take the unified DAG path with `cmdhook-*` + nodes. + +## Semantic Differences from the Legacy Sequential Path + +The unified DAG preserves user-observable behavior for `azd provision` and +`azd deploy` when run standalone. A small number of deliberate deviations exist +for the `azd up` path; they are documented here so they are discoverable during +code review and triage. + +1. **`predeploy` project command hook runs concurrently with packaging.** + The `cmdhook-predeploy` node depends only on provisioning, and the packaging + chain (`cmdhook-prepackage` → `event-prepackage` → `package-` → + `event-postpackage` → `cmdhook-postpackage`) starts in parallel with + provisioning. `cmdhook-predeploy` therefore overlaps with the packaging + chain. This is intentional (maximum overlap; packaging is a local operation + that cannot meaningfully observe predeploy state). The `predeploy` hook + still runs before `publish-` and `deploy-` because + `event-predeploy` gates both, and the legacy `postpackage`-before-`predeploy` + ordering is preserved because `event-predeploy` also depends on + `cmdhook-postpackage`. + +2. **`project.EventDeploy` Before listeners observe packaged artifacts.** + `event-predeploy` depends on every `package-` step (in addition to + `cmdhook-predeploy`), so Before-listeners see the finished package set. + The legacy sequential path fired predeploy after packaging for the first + service only and before packaging for subsequent services; the DAG path + makes this ordering deterministic. + +3. **`--output json` with multi-layer `provision`.** + The legacy path emitted one JSON state dump per layer. The DAG path emits + a single JSON dump (success or failure) using the first layer's manager + after all layers complete. Consumers that parsed per-layer JSON on + multi-layer deployments must switch to parsing a single document. + +## Implementation Notes for Readers + +Things a reader of the code should know before editing: + +1. **`pkg/exegraph` is pure** — the engine imports only stdlib + OTel. It never + reaches into azd-specific types. Adding an azd dependency here is a red flag; + put integration glue in `internal/cmd/` instead. + +2. **Step struct has no `Timeout` field.** Earlier drafts had one; it was + promoted to a scheduler-wide `RunOptions.StepTimeout` because every production + caller wanted the same budget for every step in a given run. If you need + truly per-step timeouts, add them to `Step` and combine with `RunOptions.StepTimeout` + via `min()` inside `runStep`. + +3. **Cancellation has two distinct flavors** and they are classified differently: + - **Parent/FailFast cancel** (`runCtx.Err() != nil`) → affected steps are + recorded as `StepSkipped`, their errors are *not* appended to `allErrors`, + and they do *not* appear in `result.Failed`. The canceling error (`ctx.Err()`) + is appended once at run boundary if no other error exists, so + `ctx.Cancel()` always surfaces a non-nil `Run()` error. + - **Per-step `StepTimeout` expiration** (`runCtx.Err() == nil`) → a real + step failure. Appears in `allErrors` and `result.Failed`, triggers + FailFast tear-down of peers. + Search for `isSchedulerCancel` in `scheduler.go` for the classification code. + +4. **`provision_graph.go` single-layer path is deliberately a one-node graph.** + It could be written as "call the manager directly, skip the engine," but + that would require two code paths. The one-node graph uses the injected + `provisionManager` verbatim, preserves mock-friendliness for unit tests, and + keeps observability (spans, events) identical across 1-layer and N-layer + runs. Do not "optimize" it away. + +5. **Preview (`--preview`) bypasses the engine entirely.** Preview is always + single-layer, has no hooks, no env writes, no cache invalidation, and its + UX is disjoint from provision. The bypass lives in `provisionPreview` — + see `provision_graph.go` around the `--preview` check. + +6. **Error unwrapping at the boundary is non-negotiable.** The scheduler prefixes + step errors with `step "NAME" failed: `. Callers in `provision_graph.go` and + `deploy.go` run the result through `unwrapStepErrors` before handing it to + the existing wrappers (`wrapProvisionError`, etc.) so user-facing errors look + identical to the legacy path. Skipping this unwrap breaks golden tests and + UX expectations. + +7. **Subscription/location prompts happen before the graph starts.** For + multi-layer provision, the shared manager resolves subscription & location + once (interactively if needed) *before* per-layer managers are constructed. + Otherwise two layers would race to prompt the user. See the comment block + in `provisionLayersGraph` describing the "resolve before spawn" invariant. + +8. **Per-layer env clones are deep copies, but cross-layer hook writes need a + reload.** Each multi-layer step gets its own `Environment` clone so + concurrent `env.DotenvSet` writes don't race. Outputs from successful layer + completion are written back into the shared env. Cross-layer output + references are resolved by `layer_deps.go` at graph-build time (not at + runtime). Hook-mediated edges (where layer A's `postprovision` hook writes + `azd env set FOO=bar` that layer B's `.bicepparam` reads) are NOT + detectable statically — authors must declare them via + `infra.layers[].dependsOn`. + + `runProvisionSingleLayer` runs an 8-step lifecycle inside one scheduler + step: pre-hooks → pre-event → `mgr.Deploy` → env merge → service event → + post-event → post-hooks → **reload** `deps.env` from disk. The merge step + reloads `deps.env` *before* applying outputs and saving, so the parent + process's stale in-memory state never clobbers subprocess writes from + pre-hooks. The final reload (step 8) re-syncs `deps.env` after post-hook + subprocess writes, so any downstream layer's clone observes those writes + at its own step 0. Both reloads happen under `envMu`. Concurrent sibling + layers (no `dependsOn` edge) intentionally do NOT see each other's + mid-flight hook writes — that's the contract `dependsOn` exists to + override. The merge / reload helpers are extracted as + `mergeLayerOutputsLocked` / `reloadSharedEnvLocked` and tested directly. + +9. **Build gate is policy-driven, not Aspire-specific.** The DAG builder + (`service_graph.go`) is ecosystem-agnostic: it consumes an opaque-string + `buildGateKey` callback on `serviceGraphOptions`. Services returning the + same non-empty key serialize on the first one — "first wins, rest wait" — + and services returning `""` run in full parallelism. Today the only gate + in use is `aspireBuildGateKey` (in `cli/azd/internal/cmd/aspire_gate.go`), + which returns `"aspire"` for services whose `DotNetContainerApp` options + are populated by the Aspire importer. That gate exists because the .NET + AppHost build is shared state, not because deploy itself can't + parallelize. When Aspire moves into an extension, only that helper — not + the DAG builder — has to move with it. + +10. **`deploy_progress.go` renders differently in interactive vs CI.** + Interactive mode rewrites terminal lines with ANSI escapes; + non-interactive mode (detected via `console.IsSpinnerInteractive()`) + prints one line per state transition and makes `RenderFinal` a no-op. + This is deliberate: `--output json` must never have progress noise + interleaved with the JSON document. + +11. **`runStep` panic recovery converts panics to errors, not process aborts.** + A panicking step is logged with stack trace and its status is `StepFailed`. + FailFast tear-down still applies. If you want "crash the whole CLI on + panic" behavior, remove the `recover()` in `runStep` — but understand that + will take down parallel peer steps mid-flight. + +12. **OTel attribute keys live in `internal/tracing/fields/fields.go`.** + When adding a new `exegraph.*` span attribute, define the `AttributeKey` + there (not inline in `scheduler.go`) so the telemetry schema stays + centralized. + +13. **Multi-layer provision adoption telemetry.** Each `azd provision` / + `azd up` run that takes the multi-layer path emits four `provision.layer.*` + attributes on the ambient command span (defined alongside the + `exegraph.*` keys in `internal/tracing/fields/fields.go`): + + | Attribute | What it measures | + |---|---| + | `provision.layer.count` | Total `infra.layers[]` declared | + | `provision.layer.max_parallel` | Largest dependency level after analysis (max achievable parallelism) | + | `provision.layer.safe_fallback_count` | Layers that triggered the safe-by-default detector fallback | + | `provision.layer.explicit_dependson_count` | Layers using `infra.layers[].dependsOn` | + + These are SystemMetadata only — counts, no template content — and let + the azd team answer "what fraction of projects use multi-layer?", + "how parallel is the typical project?", and "how often does the + safe-by-default fallback engage on real templates?" without inspecting + user content. As of this PR, an `org:Azure-Samples filename:azure.yaml` + audit found **zero awesome-azd templates using multi-layer + `infra.layers[]`**; only three community user repositories on GitHub + declare it.
