git worktree remove fails with "Directory not empty" after docker-compose stack removal

Removing a git worktree that had been running a Docker Compose dev stack (per-worktree isolated stack, bind mounts pointing into the worktree). git 2.54.0, Docker 29.4.0, Compose v5.1.2, macOS. The worktree was spotless before the attempt: git status --porcelain empty, no stashes, branch 0/0 vs…

Docker Compose bind mount FileNotFoundError after host file rename write

Docker compose container suddenly gets FileNotFoundError for a single-file bind mount (e.g. ./protected.yaml:/app/protected.yaml ) even though the file clearly exists on the host. Started after the host file was edited by a tool that writes via rename (secrets managers, editors with atomic save).

Docker Compose persistent container loses network connectivity when compose config changes while running. Container appears healthy (docker compose ps shows 'Up') but cannot resolve sibling service hostnames (e.g. 'db'). Caused by network recreation on config change — Compose destroys and recreates…

Docker Compose services that reference a locally-built image (via image: tag) but lack both a build: directive and pull_policy: never will fail with 'pull access denied' when the image name uses

Docker Compose services that reference a locally-built image (via image: tag) but lack both a build: directive and pull_policy: never will fail with 'pull access denied' when the image name uses a private/nonexistent registry prefix. Services with build: but no pull_policy: never produce warnings…
