Closes#53635
Release Notes:
- Fixed issues with Windows pathing when calculating target workspace
directory for dev containers
`supports_compose_buildkit()` returned `!self.is_podman()`, assuming
every Docker install has buildx. On setups like Colima where the buildx
CLI plugin isn't installed, this causes builds to fail with "classic
builder doesn't support additional contexts" since `DOCKER_BUILDKIT=1`
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.

## Details
- The [devcontainer CLI writes the `devcontainer.metadata` label as a
bare JSON object](https://github.com/devcontainers/cli/issues/1054) when
there is only one metadata entry (e.g. docker-compose devcontainer with
a Dockerfile and no features)
- Zed's `deserialize_metadata` only accepted a JSON array, causing
deserialization to fail with `invalid type: map, expected a sequence`
- This made it impossible to attach to existing docker-compose
devcontainers created by the devcontainer CLI or VS Code
The fix tries parsing as an array first, then falls back to parsing as a
single object wrapped in a vec. This mirrors how the [devcontainer CLI
itself reads the
label](https://github.com/devcontainers/cli/blob/main/src/spec-node/imageMetadata.ts#L476-L493).
An upstream fix has also been submitted:
https://github.com/devcontainers/cli/pull/1199
## Reproduction
1. Create a docker-compose devcontainer with a Dockerfile and no
features:
`.devcontainer/devcontainer.json`:
```json
{
"name": "repro",
"dockerComposeFile": "docker-compose.yml",
"service": "app",
"remoteUser": "root"
}
```
`.devcontainer/docker-compose.yml`:
```yaml
services:
app:
build:
context: .
dockerfile: Dockerfile
command: sleep infinity
volumes:
- ..:/workspace
```
`.devcontainer/Dockerfile`:
```dockerfile
FROM ubuntu:24.04
```
2. `devcontainer up --workspace-folder .`
3. Open the folder in Zed, fails with metadata deserialization error
Release Notes:
- Fixed attaching to a devcontainer that has a single metadata element
which was started with `devcontainer-cli`

Closes#52928
Release Notes:
- Fixed handling of multi-stage and stage-specified dockerfiles in dev
container manifests
- Fixed the way we find the base image in a dev container when build
args need expansion
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.

for all volume mounts.

Fixes a parsing issue where docker env var key/value pairs can contain
an "=" character in the value. This is pretty common and present in all
[nvidia/cuda](https://hub.docker.com/r/nvidia/cuda) docker images. Also
adds some tests for env var parsing.

Release Notes:
- Fixed a parsing failure where docker env var key/value pairs can
contain an "=" character in the value.
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

## 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
