VS Code's Dev Containers extension auto-copies the host's gitconfig into the container at attach time using `(dd ...) >> /home/node/.gitconfig`. A read-only bind mount of ~/.gitconfig blocks that write, so attach failed with `cannot create /home/node/.gitconfig: Read-only file system`. Making it read-write would let the append succeed, but the bind mount means the host file and the container file are the same file — VS Code's append would double the host gitconfig contents on every container start. Drop the ~/.gitconfig bind mount entirely. VS Code's auto-copy is the purpose-built mechanism for this, gives the container the host's user.name / user.email transparently, and avoids both the read-only write failure and the append-duplication trap. The container ends up with a writable /home/node/.gitconfig that's a copy of the host's, not a mount. The remaining six bind mounts (.claude, .codex, .cursor, .ssh, .config/git, .config/gh) keep their existing modes — XDG-style git config under ~/.config/git is unaffected by VS Code's auto-copy (which only targets ~/.gitconfig), so its read-only bind mount stays. Also remove the `.gitconfig` touch from ensure-host-config-dirs.cjs (now unnecessary) and update the README CLI-state table, sharing explanation, and troubleshooting row to reflect that gitconfig flows in via VS Code auto-copy rather than the bind mount.

// 1. CLI config dirs — bind-mounted from the host so the developer's

|
|
// for Claude Code / Codex / Cursor + git identity + gh auth are
|

// immediately available inside the container, and changes inside the

|
// container flow back to the host. ~/.gitconfig is read-only so
|
|
// container-side `git config --global` doesn't leak to host config.
|
|
// For high-trust environments where host and container should NOT
|
|
// share credentials, swap these three CLI bind mounts for
|
|
// per-devcontainer named volumes (Anthropic's reference pattern).
|
|
//
|
|
// 2. Per-instance state — `${devcontainerId}` scoped: history and npm
|
|
// cache survive container rebuilds but stay isolated between
|
|
// sibling devcontainer instances.
|
|
//
|
|
// 3. Per-workspace-name AND per-instance state — workspace `node_modules`
|
|
// volumes use both `${localWorkspaceFolderBasename}` (debuggable in
|
|
// `docker volume ls`) and `${devcontainerId}` (collision-free between
|
|
// sibling instances of the same repo, e.g., ~/work/GitNexus vs
|
|
// ~/projects/GitNexus). Keeps tree-sitter native binaries and
|
|
// onnxruntime off the workspace bind mount (the real Win/Mac perf win).
