Toni AlataloandClaude Opus 4.7 685fea0b4a dev_container: Align compose project name with reference CLI (#54302)
> **Draft / open question for maintainers.** The failure mode this fixes
is narrow — a new-Zed-created container exists under the `name`-field
project while a CLI-derivation tool (`@devcontainers/cli`, VS Code)
operates on the same folder (the container persists in Docker, so the
originating Zed session doesn't need to still be open). See issue #54255
failure mode 3 and the fixture's step 6.
>
> I'd like to pose this as a question rather than a claim: is matching
`@devcontainers/cli`'s `getProjectName` precedence something the project
wants to take on, given the narrowness of the bug? I wrote this
implementation mostly as a way to explore what parity would actually
cost — happy to close it if you'd rather leave it as-is, or pare it down
(e.g. just rule 4) if a partial match is preferable.
>
> The broader value beyond this specific bug: devcontainer impls
agreeing on the same project name means containers created by Zed, the
devcontainer CLI, and VS Code are interchangeable for the same folder,
which feels worth it to me — but you know the project's priorities
better.
>
> Folds in #54068 (detection) — closing that PR unmerged; its
`MultipleMatchingContainers` error lands here.

Closes #54255

## Summary

**Match `@devcontainers/cli`'s full `getProjectName` precedence.**
Replaces `safe_id_lower(devcontainer.json's name)` with the five-step
chain the reference CLI walks (see [`src/spec-node/dockerCompose.ts` in
devcontainers/cli](https://github.com/devcontainers/cli/blob/main/src/spec-node/dockerCompose.ts)):

1. `COMPOSE_PROJECT_NAME` from the local environment.
2. `COMPOSE_PROJECT_NAME=` in the workspace `.env` file.
3. Top-level `name:` on the merged compose config, when at least one
fragment declared it explicitly.
4. `${workspaceFolderBasename}_devcontainer` — only when the first
compose file's directory is `<workspace>/.devcontainer/`.
5. Otherwise, the plain basename of the first compose file's directory
(no suffix).

The old Zed implementation diverged at every one of those inputs: any
user setting `COMPOSE_PROJECT_NAME`, shipping a `.env` with one,
declaring a top-level compose `name:`, or pointing `dockerComposeFile`
outside `.devcontainer/` (e.g. `"../docker-compose.yml"`) got a
different project namespace than the CLI and VS Code, producing two
compose projects for the same folder.

Adds a small `sanitize_compose_project_name()` helper implementing the
CLI's rules (lowercase + strip `[^-_a-z0-9]`) — notably preserving
hyphens, which `safe_id_lower` would have replaced with underscores.

Adds two helpers used by the precedence walk:
- `parse_dotenv_compose_project_name` — line scan extracting
`COMPOSE_PROJECT_NAME=…` from the workspace `.env`, matching the subset
the CLI's regex dotenv reader recognizes.
- `compose_fragment_declares_name` — parses each compose fragment with
`yaml-rust2` (already a transitive workspace dep; slated to become a
direct dep via #53922) and checks for a `name` key on the root mapping
(block, quoted, or flow style all work), matching the CLI's own
`yaml.load`. `docker compose config` always injects `name: devcontainer`
into its merged output when no fragment declared one, so rule 3 needs to
distinguish the user-provided case from the injected default — this
helper supplies that signal. On YAML parse failure it returns "not
declared" (rule 4 applies), matching the CLI's fallback.

`project_name()` becomes async and fallible (`async fn
project_name(&self) -> Result<String, DevContainerError>`) so it can
load the `.env` file and each compose fragment via `self.fs.load`. Four
call sites now `.await?` the derivation. Real I/O errors on the `.env`
read propagate as `FilesystemError` (matching the CLI's narrow
`ENOENT`/`EISDIR` swallow); fragment-rescan read errors are logged and
skipped (matching the CLI's broader try/catch over its fragment read +
parse).

The `name` field is still used as the features image-tag prefix
(`generate_features_image_tag`); only the compose project namespace is
decoupled from it.

**Duplicate-container detection (from #54068).** When
`check_for_existing_container`'s label-based lookup returns more than
one match, propagate `MultipleMatchingContainers(ids)` with instructions
to clean up the stale one(s). This covers the mixed-version upgrade edge
case where a pre-fix Zed left a container under the legacy project name
alongside a CLI-style one — transparent to users in the common case (one
tool, one container), explicit error when two legacy siblings need
manual cleanup.

## Why

Full write-up with verified fixtures and captured output: #54255.

Three failure modes from the same root cause, all resolved by this
change:

1. **Interop** — opening a folder in both Zed and `devcontainer up` (or
Zed and VS Code) creates two compose projects with identical
`devcontainer.local_folder` + `devcontainer.config_file` labels,
breaking the spec's uniqueness invariant.
2. **Cross-worktree silent db/volume reuse** — if multiple git worktrees
share a `devcontainer.json` with the same `name`, Zed uses the same
compose project for all of them; Compose reuses stateful siblings (db,
cache, localstack) by config-hash, so worktree B silently inherits
worktree A's database. Fixture + captured output:
[antont/zed-devcontainer-db-share-repro](https://github.com/antont/zed-devcontainer-db-share-repro).
3. **Mixed-version Zed sessions** — the Rust impl landed in stable
v0.232.2 (2026-04-15, #52338). Older Zed (≤v0.231.x) shelled out to
`@devcontainers/cli` so it used the reference derivation. The collision
shows up when a new-Zed-created container exists under the name-field
project while a CLI-derivation tool (old Zed, `devcontainer up`, VS
Code) operates on the same folder.

## Migration / compatibility

Existing Zed-created containers (under the old `safe_id_lower(name)`
project) continue to be found via `check_for_existing_container`'s
label-based lookup — they're looked up by `devcontainer.local_folder` +
`devcontainer.config_file`, not by project name. A user with duplicate
legacy containers from a prior Zed session sees
`MultipleMatchingContainers` with cleanup instructions.

## Revision — 2026-04-22

Revised per @KyleBarton review on the prior version:
- Swapped the YAML parser from `serde_yaml_ng` to `yaml-rust2` (already
transitive via `tree-sitter-yaml`; net reduction of one direct workspace
dep; also what #53922 will pull in).
- Dropped the mixed-version tiebreak (`pick_canonical_container`) and
its `com.docker.compose.project` serde label. The edge case it covered
is transient enough to address via the explicit
`MultipleMatchingContainers` error rather than permanent tiebreaking
code.
- Folded #54068's detection commit into this PR; #54068 closed unmerged.
- Rebased onto `main`.

## Test plan

- [x] `cargo test -p dev_container --lib` — 89 passed, including:
  - `sanitize_compose_project_name_matches_cli_rules`
- `--project-name` assertion added to
`test_spawns_devcontainer_with_docker_compose`
  - `check_for_existing_container_errors_when_multiple_match`
  - `derive_project_name_env_wins_over_everything`
  - `derive_project_name_dotenv_wins_over_compose_and_fallback`
  - `derive_project_name_compose_name_wins_over_fallback`
- `derive_project_name_skips_compose_name_when_not_explicitly_declared`
-
`derive_project_name_omits_suffix_when_compose_file_outside_devcontainer_dir`
  - `derive_project_name_normalizes_compose_path_for_rule_4`
- `compose_fragment_declares_name_detects_top_level_name_key` (covers
block, quoted-key, and flow-style roots, plus parse failure →
not-declared)
  - `is_missing_file_error_only_accepts_notfound_and_isadirectory`
- [x] `cargo fmt --all` — clean
- [x] `./script/clippy -p dev_container` — clean
- [x] **End-to-end with fixture**
[antont/zed-devcontainer-compose-test](https://github.com/antont/zed-devcontainer-compose-test):
  - Build `zed` from this branch.
- Clean slate: `docker ps -a --filter
"label=devcontainer.local_folder=$PWD" -q | xargs -r docker rm -f`
- `zed --dev-container /path/to/devcontainer-compose-test` → Zed creates
container under project `devcontainer-compose-test_devcontainer` (was
`compose_duplicate_repro` before the fix).
- `devcontainer up --workspace-folder $PWD` → CLI reports the same
`containerId` Zed created; no second compose project is introduced.
- Captured: `devcontainer-compose-test_devcontainer-app-1`,
`composeProjectName: "devcontainer-compose-test_devcontainer"` reported
by both tools.

Release Notes:

- Fixed dev container Docker Compose project name now matches the full
`getProjectName` precedence from the reference devcontainer CLI
(`COMPOSE_PROJECT_NAME` in the environment, then in the workspace
`.env`, then an explicit top-level `name:` on the merged compose config,
then the basename of the first compose file's directory — with the
`_devcontainer` suffix only when that directory is
`<workspace>/.devcontainer`). This prevents duplicate containers when
the same folder is opened with both Zed and the devcontainer CLI / VS
Code.

Sandro Meier 5430029668 dev_container: Resolve compose service build args in Dockerfile expansion (#54270)
For docker-compose-based dev containers, build args live on the primary
compose service's `build.args`, not on `dev_container.build` (which is
`None` in the compose case). `expanded_dockerfile_content` only
consulted the latter, so `${…}` references in the service's Dockerfile —
e.g. `FROM ${BASE_IMAGE}` — were never substituted. Downstream callers
then invoked `docker inspect "${BASE_IMAGE}"` and `docker pull
"${BASE_IMAGE}"`, both of which fail and the dev container fails to
start.

A new unit test `test_expands_compose_service_args_in_dockerfile` mounts
a Dockerfile with `FROM ${BASE_IMAGE}` backed by a compose service whose
`build.args` define `BASE_IMAGE=test_image:latest`, and asserts both
`expanded_dockerfile_content` and `image_from_dockerfile` produce the
resolved reference.

Ivan Mironov 30403fa913 Fix devcontainer localEnv/containerEnv substitution when variable is undefined (#53728)
Existing code replaces only the variables that are present in the
environment. It ignores references to undefined variables and leaves
them as is.

Consider following devcontainer.json:

```json
{
  ...
  "remoteEnv": {
    "RUSTFLAGS": "${localEnv:RUSTFLAGS}"
  },
  ...
}
```

Existing code will set RUSTFLAGS inside the dev container to a correct
value only if RUSTFLAGS is defined outside the dev container. If
RUSTFLAGS is not defined outside, Zed will erroneously set RUSTFLAGS to
`${localEnv:RUSTFLAGS}`.

This patch fixes this by replacing such references with either empty
strings or provided default values (`${localEnv:VARNAME:default}`).

This patch also removes replacement of `\` with `/` for environment
variables. Existing code makes no sense as simple replacement will not
magically make Windows paths valid on *nix. It is also guaranteed to
break things: think about passing passwords via env vars, for example.

I also noticed that, for some reason, existing code serializes k-v maps
to JSON, then tries to replace the references, and after that
deserializes modified JSON back. I believe that this is horribly wrong
and may have some security implications. This is out of the scope of
this patch. And I hope that somebody from the Zed team will provide the
reasoning behind this code.

Toni AlataloandClaude Opus 4.6 7fde238bce dev_container: Resolve compose dockerfile path relative to build context (#53860)
## Context

When a Docker Compose service specifies `context: ..` and `dockerfile:
.devcontainer/Dockerfile`, Zed resolves the dockerfile path relative to
the compose file's directory instead of the build context. This produces
a doubled path like `.devcontainer/.devcontainer/Dockerfile` which
doesn't exist.

Per the [Docker Compose
spec](https://docs.docker.com/reference/compose-file/build/#dockerfile),
the `dockerfile` field is relative to the build context directory.

The fix resolves the context directory first (relative to the compose
file), then joins the dockerfile path to that.

Closes #53473

## Prior art

This fix is extracted from #53170 by @zdeneklapes, which addresses this
bug among several other dev container startup issues. This PR isolates
the dockerfile path resolution fix into a focused change to make it
easier to review and merge independently.

Differences from #53170:
- **Scope**: Only the dockerfile-relative-to-context fix, not the other
fixes (compose build args preservation, remote user fallback, Docker
inspect labels, etc.)
- **Implementation**: Inline resolution in `dockerfile_location()`
rather than separate helper methods
- **Absolute path handling**: Handles absolute dockerfile and context
paths
- **Tests**: Two test cases — compose file inside `.devcontainer/` with
`context: ..`, and compose file at project root with `context: .`

## How to Review

Single file change in
`crates/dev_container/src/devcontainer_manifest.rs`:
- **Fix** (line 234-252): Resolve build context relative to compose file
directory, then join dockerfile to that, instead of joining dockerfile
to `config_directory` directly. Uses `normalize_path` to resolve `..`
components.
- **Tests**: Two new `FakeDocker` compose config entries and
corresponding tests asserting correct resolved paths.

alone isn't enough without the plugin.

Now probes for `docker buildx version` at construction time and caches
the result. When buildx isn't found, the existing scratch-image fallback
path (same one Podman uses) kicks in instead.

Closes #53890

Release Notes:

- Fixed dev container builds failing on Docker installations without the
buildx plugin.

Closes #53263

Properly deserializes the app_port field, even if it is an array of
strings. Also, removes app_port from consideration when building a
docker-compose-based dev container, since the spec specifies that it
only applies to non-docker-compose dev containers.

Release Notes:

- Fixed app_port deserialization in dev container

Peter SiegelandKyleBarton d1af853505 dev_container: Preserve build context for docker-compose Dockerfiles (#53140)
When a Docker Compose service specifies a build context, the generated
override file was replacing it with an empty context directory. This
meant Dockerfiles that reference files relative to their build context
(e.g. `COPY . /app`) would fail. The fix preserves the original build
context from the compose service, falling back to the empty context
directory only when no context was specified.

Peter SiegelandKyleBarton 0410960442 dev_container: Make volumes key and source key in volume mounts optional (#53137)
Fixes some issues concerning volume mounts in the `dev_container`
integration:
1. Docker Compose services that don't define a volumes key cause
deserialization to fail because the field was required. This field is
not strictly necessary, i.e. for other services in a docker compose
devcontainer configuration which the editor is not attached to.
1. Volume mounts where source or target is absent (e.g. `tmpfs` mounts
that only need a target) also fail to parse because both fields were
required. This makes the source key optional, matching the Docker
Compose spec.

Release Notes:

- Fixed devcontainer initialization erroneously requiring each service
to have a volumes key.
- Fixed devcontainer initialization erroneously requiring source keys
for all volume mounts.

KyleBarton f21062860f Ensure updateUID gets run for docker-compose and plain images (#53106)
Dev Containers should run a script which updates the remote UID of the
image user, so that files are still accessible. This was being run
incorrectly (on the Docker-compose side) or not at all (in the case of a
plain dev container image). This change fixes this

KyleBarton 4b1bc30b49 Dev containers native implementation (#52338)
## Context

Closes #11473

In-house Zed implementation of devcontainers. Replaces the dependency on
the [reference implementation](https://github.com/devcontainers/cli) via
Node.

This enables additional features with this implementation:
1. Zed extensions can be specified in the `customizations` block, via
this syntax in `devcontainer.json:
```
...
  "customizations": {
    "zed": {
      "extensions": ["vue", "ruby"],
    },
  },

```
2.
[forwardPorts](https://containers.dev/implementors/json_reference/#general-properties)
are supported for multiple ports proxied to the host
