New bin/pos-docker-stack: docker ps output grouped by Docker Compose project (stack). Each stack is a sorted section (name, status, ports); containers without a compose project land in a Standalone group at the end. Running only by default, -a|--all includes stopped/exited. Status colored on a terminal; summary line 'Stacks: N containers: N standalone: N'; exit 0 when empty. Data via docker ps --format with \x1f delimiters (project label com.docker.compose.project from compose v2); parsed with awk -F'\x1f' + IFS=$'\x1f' read — tab/pipe delimiters are IFS whitespace or appear in values (DEV.md:213). Dash padding via sed, not tr (multi-byte). Deps guard (docker) before --help; no stdin. Docs: POS.md docker row + detail, howto/docker.md table + section, bin/pos usage EXAMPLES, AGENT_Context Common Tasks row. Verified: stub suite 23/23, live daemon runs, dispatch, make gen && make check, make lint 0 FAIL / 0 WARN.

Usage: pos docker stack [-a|--all]
|
|
|
|
Show running containers grouped by their Docker Compose stack (project).
|
|
Non-compose containers (no stack) are listed under a "Standalone" group
|
|
at the end.
|
|
|
|
Flags:
|
|
-a, --all Include stopped/exited containers too (like docker ps -a)
|
|
-h, --help Show this help
|
|
|
|
Exit codes:
|
|
0 Success (also when no containers are found)
|
|
|
|
Examples:
|
|
pos docker stack Grouped view of running containers
|
|
pos docker stack -a Include stopped/exited containers
