chore(release): bump version to 1.0.8 - #77
Conversation
Repair broken docker-buildx/compose plugins left after uninstalling Docker Desktop, and document the host CLI setup path. Co-authored-by: Cursor <[email protected]>
📝 WalkthroughWalkthroughThe backend now detects and repairs broken Docker Buildx and Compose plugin symlinks. Plugin status and repair hints flow through the configuration API to the settings screen. Documentation and version metadata describe the new behavior. ChangesDocker CLI plugin repair
Estimated code review effort: 3 (Moderate) | ~30 minutes Merge Risk: 🟠 High · up to The plugin repair can delete a user-managed file and can leave one of the Docker CLI plugins unrepaired when the other fails, creating concrete data-loss and broken Docker command risks; merge should wait until both behaviors are corrected.

Attempt both plugin repairs before returning an error.
EnsureCLIPlugins stops at the first ensurePlugin error, so a Compose candidate is not attempted when Buildx repair fails. Continue through both plugin names and aggregate repair errors. The fallback ProbePlugins path already computes PluginsHint.

Do not replace a non-broken plugin path.
pluginHealthy returns false for a regular file without execute permission and for other non-dangling invalid paths. When a candidate exists, Line 77 deletes that path without checking its type. This can permanently remove a user-managed plugin or file.
Only remove a verified dangling symlink. If dest exists but is not a dangling symlink, return a specific error and leave it unchanged. Also return removal errors at Lines 70 and 77 instead of discarding them.

| - **Docker CLI plugins after leaving Docker Desktop** — calf detects broken `docker-buildx` / `docker-compose` symlinks under `~/.docker/cli-plugins/` (common after trashing Docker Desktop) and relinks working copies from Homebrew, OrbStack, or PATH so `docker compose up --build` keeps working.

Docker Compose v2 docker compose up --build Buildx plugin missing classic builder fallback behavior Docker CLI versions
💡 Result:
In Docker Compose v2, the build system intelligently selects between two primary implementations: the "Classic Builder" (using the legacy Docker Engine ImageBuild API) and the "Bake Builder" (using the buildx CLI plugin) [1][2]. The selection logic is handled automatically at runtime. When docker compose up --build or docker compose build is invoked, Compose checks for the availability of the buildx plugin via the Docker CLI plugin manager [1]. If the plugin is detected and BuildKit is supported, Compose typically defaults to the Bake/Buildx implementation for enhanced features like multi-platform support, secrets, and SSH forwarding [1][2]. Regarding your query on fallback behavior: 1. Automatic Fallback: Docker Compose is designed to fall back to the Classic Builder if it cannot locate the buildx plugin on the system or if specific environment configurations (like DOCKER_BUILDKIT=0) force the legacy path [1][2]. 2. Limitations of Fallback: When the system reverts to the Classic Builder, it does not support modern BuildKit-specific syntax within your Dockerfile (e.g., RUN --mount=type=cache, additional_contexts, or secrets) [2][3]. If your Dockerfile contains these features, the build will fail with a "requires BuildKit" error, even though the command itself "succeeds" in triggering a builder [3]. 3. Missing Buildx Plugin: If your environment is configured in a way that makes the buildx plugin unavailable to the Docker CLI, Compose will log a warning indicating that the buildx plugin is required [1][4]. While the process may still attempt a build using the classic path, it effectively disables the advanced build capabilities that Compose v2 intends to provide by default [2][3]. To ensure consistent behavior, verify that the buildx plugin is correctly installed in your Docker CLI's plugin directory (commonly ~/.docker/cli-plugins or the system-wide equivalent) [4][5][6]. You can verify availability by running docker buildx version [4]. If you require specific builder configurations, you can use the --builder flag with docker compose build or set the BUILDX_BUILDER environment variable, which influences how the Bake implementation selects its underlying builder [7][8].

site:docs.docker.com compose buildx plugin required classic builder fallback docker compose build
💡 Result:
In modern Docker environments, Docker Compose typically relies on BuildKit (provided by the Buildx plugin) for image builds [1][2]. The relationship between these components, the classic builder, and fallback behavior is defined as follows: 1. Requirement of Buildx: Docker Compose V2 uses BuildKit by default to optimize builds and support parallel execution [2]. Because BuildKit is implemented via the Buildx component, having Buildx available is the standard expectation for Compose builds [1]. 2. Legacy Builder Fallback: Docker Engine v23.0 and later transitioned to BuildKit as the default builder for Linux images [1]. In environments where Buildx is not installed or not available, the Docker CLI may automatically fall back to the classic (legacy) builder for commands like docker build [1]. However, this automatic fallback is deprecated and intended only as a temporary transition mechanism; it is expected to be removed in future releases [1]. 3. Controlling the Builder: You can explicitly control which builder is used by setting environment variables [3]: - To force the use of the classic builder: Set DOCKER_BUILDKIT=0 [3]. When this variable is set to 0, docker compose build will use the classic builder [3]. - To ensure BuildKit is used: Ensure DOCKER_BUILDKIT=1 (or simply leave it unset, as it is the default) and ensure the Buildx plugin is installed [1]. 4. Deprecation Warning: When the system falls back to the classic builder due to a missing Buildx component, the CLI prints a deprecation warning [1]. If you have explicitly enabled BuildKit (DOCKER_BUILDKIT=1) but the Buildx component is missing, the command will fail with an error rather than falling back [1]. In summary, while a fallback mechanism to the classic builder exists to support legacy setups, it is officially deprecated [1]. The recommended practice is to ensure the Buildx component is properly installed to support BuildKit-based builds [1].
