💡 Result: In the current Docker Compose (v5.x as of 2026, following the Compose Specification), when a bind-mount source path targets a file that does not exist on the host: - Using short syntax (e.g., ./myfile.conf:/container/path/myfile.conf): Compose creates a directory at the source path (for backward compatibility with legacy docker-compose). The mount then fails because Docker expects the source to match the target type (file), but a directory was created instead. Result: error "invalid mount config for type 'bind': bind source path does not exist" or similar. - Using long syntax without bind.create_host_path (e.g., type: bind, source: ./myfile.conf, target: /container/path/myfile.conf): Compose does not create the source path. Docker fails the mount with "bind source path does not exist". - To explicitly create the path (mimicking short syntax behavior): bind: { create_host_path: true }. But since the target is a file, creating a directory causes a mismatch and failure. Overall behavior: The operation fails with an error. Docker does not create the missing file; it requires the exact source file to exist beforehand for a successful file bind-mount. If the source is missing, no file is created in the container—either an error occurs or (in directory auto-creation cases) a directory is mounted instead, leading to app failures. bind.create_host_path: false is fully supported in long-syntax bind mounts (per Compose Specification). Semantics: Prevents automatic creation of the missing host source path (default is true). If the path does not exist, the mount fails immediately (error as above). This is useful to enforce that the host file must pre-exist, avoiding accidental directory creation. Note: There was a bug in early v5.x (issue Citations:

When To fail fast instead of silently creating a directory, use the long syntax: Suggested Compose change volumes:
- ${CLAUDE_DIR:-~/.claude}:/data/.claude:ro
- - ${CLAUDE_DIR:-~/.claude}/claude-devtools-config.json:/data/.claude/claude-devtools-config.json:rw
+ - type: bind
+ source: ${CLAUDE_DIR:-~/.claude}/claude-devtools-config.json
+ target: /data/.claude/claude-devtools-config.json
+ read_only: false
+ bind:
+ create_host_path: falseThis change prevents auto-creation of a directory and makes the error clear. However, users will still need the file to exist beforehand—consider documenting this requirement or auto-creating a default config on first run. 📝 Committable suggestion

Mounting a specific file as a volume can be problematic if the file does not already exist on the host. If
claude-devtools-config.jsonis missing from the host's.claudedirectory whendocker compose upis run, Docker will create a directory with that name instead of a file. This will cause the application to fail with anEISDIR(Illegal operation on a directory) error when it attempts to read or write the configuration. It is recommended to ensure the file exists on the host before starting the container, or to consider mounting the entire${CLAUDE_DIR:-~/.claude}directory asrwif the read-only restriction on session data is not strictly required for your use case.
