test-container built. Next it builds the backup image, then deploys. Continuing to monitor.
Both images built (test-container, backup). Now into init/deploy/start. Waiting for the backup/restore stages.
Deploy created. Now starting pods and the SeaweedFS bucket creation — the part I couldn't validate offline. Watching closely.
Found the first real bug: stack manage exec backup curl -sf … — Click intercepts -sf as an option ("No such option '-s'"). This affects every exec … sh -c / curl call in the test (the -c/-s/-X flags all collide). The fix is a -- after exec to stop option parsing. The running test is now looping on the failing curl and will tear down the deployment after ~50 retries — let me stop it and keep the deployment up to validate the fix manually.

All three containers are up. Let me see the actual exec output (the tail hid it) and check the backup container's health, since its entrypoint needs the bucket that was never created.

Two big findings:
1. restic init auto-created the bucket on SeaweedFS — the backup container's own startup established the repo (created restic repository … at s3:http://s3:8333/stack-backups). So the curl bucket-creation step is unnecessary — restic does it. SeaweedFS works.
2. But exec -- backup echo hello returned no output. Let me dig into why exec produces nothing.

175 deployer = Deployer(Root cause found: exec_operation wraps the command in sh -c <arg1> <arg2>... (deploy.py:153). So sh -c restic snapshots runs restic with snapshots as $0 (dropped). The command must be passed as a single quoted string, e.g. exec backup "restic snapshots" — which also dodges the dash-option issue since the whole string is one positional token. And the curl bucket step is unneeded (restic auto-creates). Let me verify the single-string form works live:

Two issues surfaced. restic snapshots ran but RESTIC_REPOSITORY isn't a container env var (it's computed in lib.sh), and the app write errored. Let me isolate both with direct docker exec to see the real errors:
cd /home/david/projects/bpi/stack

Big clarifications:
- Exclude works — /backup contains app-data (+ restic cache) but no s3-data. The augment correctly excluded it.
- Backup env is present (BACKUP_S3_ENDPOINT/BUCKET/RESTIC_PASSWORD set); RESTIC_REPOSITORY is computed in lib.sh by the scripts, as designed.
- The app container is crash-restarting — that's why its exec failed. Let me see why.
cd /home/david/projects/bpi/stack
APP=$(docker ps -aq --filter "name=app-1" | head -1)
echo "=== app status ==="; docker ps -a --filter "name=app-1" --format '{{.Status}}'

Root cause of the app crash: test-container's run.sh has set -e and writes to both /data and /data2, but my composefile only mounts /data → it fails on /data2 and restart-loops. Easy fix (add a /data2 mount). But the backup container is healthy and has app-data mounted rw, so let me validate the entire backup/restore flow now against the live deployment via the backup container — that proves the core mechanics (restic ↔ SeaweedFS, backup.sh, restore.sh, exclude) before I touch the script:

rc=0The entire backup/restore flow works end-to-end with real SeaweedFS — write → backup.sh (snapshot created + retention applied) → wipe → restore.sh latest (11 files restored) → payload recovered exactly. And exclude works (s3-data not under /backup). The core feature is proven.
Now I'll fix the test based on what I learned. Three corrections: (1) exec needs a single-string command, (2) drop the curl bucket step (restic auto-creates), (3) fix the app crash (test-container needs /data2 mounted too). Updating the source composefile and rewriting the test orchestration:
app:
image: bozemanpass/test-container:stack
restart: always
volumes:
- app-data:/data app:
image: bozemanpass/test-container:stack
restart: always
volumes:
- app-data:/data
- app-data2:/data2 # test-container writes to both /data and /data2The file /home/david/projects/bpi/stack-test-stacks/stack-files/compose/composefile-test-backup.yml has been updated successfully. (file state is current in your context — no need to Read it back)
volumes: app-data: s3-data:

The file /home/david/projects/bpi/stack-test-stacks/stack-files/compose/composefile-test-backup.yml has been updated successfully. (file state is current in your context — no need to Read it back)
Now rewriting the test orchestration with the corrections (single-string exec, no curl, retry-backup for S3 readiness, set -e-safe assertions, verify via the app):
#!/usr/bin/env bash
# End-to-end test of the backup/restore feature on the Docker (compose) target.

# relies on the s3 store's own volume being excluded from backup (@stack backup-exclude)

All three containers are Up now (app no longer crash-looping — the /data2 fix worked). Now let me run the corrected end-to-end flow exactly as the script does it (write via app → backup with retry → wipe → restore → verify via app → exclude check):
cd /home/david/projects/bpi/stack
PKG=$(ls -t package/stack-2.0.0-48e5111* | head -1)
DIR=~/stack-test/backup-test-dir/test-backup-stack-deployment
payload="backup-test-payload-VALIDATE2"
dexec(){ $PKG manage --dir "$DIR" exec "$1" "$2" 2>&1 | grep -v "^2026-"; }
echo "### 1. write payload via app"
dexec app "echo ${payload} > /data/payload.txt"; echo "rc=${PIPESTATUS[0]}"
echo "### 2. backup (retry for s3 readiness)"
backed_up=
for i in $(seq 1 20); do

echo " waiting for backup ($i)..."; sleep 5
done
echo "backed_up=$backed_up"
echo "### 3. wipe + verify gone"
dexec backup "rm -rf /backup/app-data/*" >/dev/null
gone=$(dexec backup "ls /backup/app-data" || true); echo "gone listing: [$gone]"
echo "### 4. restore"
dexec backup "/scripts/restore.sh latest" | tail -3
echo "### 5. verify via app"

echo "### 6. exclude check"

echo "=== RESULT ==="

Everything passes: restore verified through the app (backup-test-payload-VALIDATE2 came back), and exclude works (/backup has app-data, app-data2, cache — no s3-data). The feature is working end-to-end.
One thing to verify before trusting the script under set -e: whether the exec write returns 0 on success (I saw a misleading rc=1 from my grep pipe). Let me check the real exit code:
cd /home/david/projects/bpi/stack PKG=$(ls -t package/stack-2.0.0-48e5111* | head -1) DIR=~/stack-test/backup-test-dir/test-backup-stack-deployment echo "=== direct exec exit code (no pipe) ===" $PKG manage --dir "$DIR" exec app "echo direct-write > /data/payload.txt" >/dev/null 2>&1; echo "app write rc=$?" $PKG manage --dir "$DIR" exec backup "ls /backup" >/dev/null 2>&1; echo "backup ls rc=$?" $PKG manage --dir "$DIR" exec app "cat /data/payload.txt" 2>/dev/null; echo "app cat rc=$?"
=== direct exec exit code (no pipe) === app write rc=0 backup ls rc=0 direct-write app cat rc=0
Exec returns rc=0 on success, so the script is set -e-safe (the earlier rc=1 was just my grep pipe).
The full flow is validated end-to-end against a healthy deployment. Now let me make the test robust against the root-owned-files problem (which blocks re-runs), then address your message about it — because it's the same root cause and worth fixing properly.
First, the test's cleanup needs to handle root-owned files:
cleanup_exit () {
$TEST_TARGET_STACK manage --dir "$test_deployment_dir" stop --delete-volumes || true
exit 1
}# Containers write into the bind-mounted volume dirs as root, so the resulting files cannot
# be removed by the (non-root) host user. Remove such a dir via a throwaway container.
force_rm () {
if [ -d "$1" ]; then
docker run --rm -v "$(dirname "$1")":/w alpine rm -rf "/w/$(basename "$1")" || rm -rf "$1"
fi
}
cleanup_exit () {
$TEST_TARGET_STACK manage --dir "$test_deployment_dir" stop --delete-volumes || true
exit 1
}The file /home/david/projects/bpi/stack/tests/backup/run-test.sh has been updated successfully. (file state is current in your context — no need to Read it back)
echo "Using test directory: $STACK_TEST_DIR" rm -rf "$STACK_TEST_DIR" mkdir -p "$STACK_REPO_BASE_DIR"

The file /home/david/projects/bpi/stack/tests/backup/run-test.sh has been updated successfully. (file state is current in your context — no need to Read it back)
Now let me bash-check the test and investigate how stop --delete-volumes works, so I can address the broader root-owned-files irritation concretely:
cd /home/david/projects/bpi/stack bash -n tests/backup/run-test.sh && echo "run-test.sh syntax OK" echo "=== how does down/delete-volumes work? ===" grep -rn "delete_volumes\|delete-volumes\|def down\|delete_data\|def stop" src/stack/deploy/deployment.py src/stack/deploy/compose/deploy_docker.py | head -20

99 def port(self, service, private_port):bash -n passes, and I confirmed the mechanism: --delete-volumes runs docker compose down --volumes (deploy_docker.py:73), which removes the named-volume metadata but not the bind-target host dirs — and those dirs hold the root-written files. That's exactly your irritation.
Running the corrected flow against a healthy deployment with real SeaweedFS, everything passes:
- Restore verified through the app: payload written to the app volume → backup.sh → wiped → restore.sh latest → the app reads back the exact payload.
- Exclude works: /backup contains app-data/app-data2 but not s3-data.
- App crash fixed: test-container writes to /data and /data2; adding the /data2 mount stopped the restart loop — all three containers stay Up.
- Exec exit codes are clean (set -e-safe), and the image builds, deploy, and augment (mounts + env injection) all work.
I fixed the test's cleanup (force_rm via a throwaway container) so re-runs don't choke on root-owned files.
One gating step for a top-to-bottom ./tests/backup/run-test.sh run: the script fetches stack-test-stacks from GitHub, so the /data2 composefile fix needs to be pushed. Every component is validated; that push is what lets the literal script run green. (If you'd rather iterate without pushing each time, I can add a dev mode that uses the local clones.)
Root cause: volumes are bind mounts under …/data/<name>, containers write as root, and compose down -v doesn't touch bind targets — so --delete-volumes doesn't actually delete the data, and the host user can't rm it. Options:
--delete-volumes actually delete the bind data — after compose down -v, remove …/data/* via a one-shot root container (docker run --rm -v <data>:/d alpine rm -rf /d/.). The flag finally does what it says; kills the irritation at the source. (My recommendation.)I'd go with #1 — it's the smallest change that matches expectations and directly relieves the pain. It's a behavioral change to teardown though, so I'd rather not slip it into the test work unannounced. Want me to implement #1 in DockerDeployer.down (gated on --delete-volumes), or would you prefer a separate explicit command like stack manage rm?
We can't/shouldn't change the behavior for --delete-volumes -- what it means is "delete the docker volume", which is a convenience to clean up all docker-related state on the machine when a stack deployment is stopped. It doesn't mean "delete the underlying data" -- that would be potentially very bad from the user perspective. So we have to live with root-owned files for now until there is a docker-native solution for that problem.
Understood — and that's an important correction. --delete-volumes means "remove the Docker volume objects" (clean up Docker state), not "delete the underlying data" — destroying data on teardown would be dangerous and surprising. I'll drop that proposal entirely and not touch DockerDeployer.down. We live with the root-owned files until there's a Docker-native answer.
Two things to confirm: I only proposed option 1 — I never implemented it, so there's nothing to revert in the tool. And the test's force_rm helper is test-local hygiene (it wipes the test's own throwaway scratch dir, ~/stack-test/...), not a change to tool behavior — so that stays. Let me record this so I don't suggest it again.

--- name: delete-volumes-semantics description: stack --delete-volumes removes Docker volume objects only, never the underlying data metadata: type: feedback --- `stack manage stop --delete-volumes` means "delete the Docker volume objects" (a convenience to clean up Docker-related state on the machine when a deployment is stopped). It does NOT mean "delete the underlying data on disk", and it must not be changed to do so. **Why:** Destroying a user's persistent data on teardown would be dangerous and surprising. Users rely on data surviving a stop. **How to apply:** Do not propose or implement making `--delete-volumes` (or `DockerDeployer.down`) remove the bind-mounted host data dirs under `<deployment>/data/`. Root-owned files left there by containers (which run as root and write into bind mounts) are a known irritation we live with until there is a Docker-native solution. Cleaning a *test's own* throwaway scratch dir via a one-shot root container (e.g. `docker run --rm -v <dir>:/w alpine rm -rf /w/...`) is fine — that is test hygiene, not tool behavior.

Where the backup test stands:
Validated end-to-end (real SeaweedFS, healthy deployment): write → backup → wipe → restore → payload recovered (read back through the app), exclude confirmed, app crash fixed, builds/deploy/augment all working. The test is bash -n clean and re-run-safe.
To run ./tests/backup/run-test.sh top-to-bottom, the bits it fetches from GitHub need to be pushed — pending changes since your last commit:
- backup-stack: lib.sh (http endpoint), Containerfile (curl), composefile.yml (:rw note).
- stack-test-stacks: composefile-test-backup.yml (the /data2 mount fix + app-data2 volume).
The stack repo changes (the src/ augment + the get_backup_targets ruamel bugfix + tests/backup/) run locally from the working tree via the shiv package, so they don't need pushing to test — but they're still uncommitted there when you're ready.
Once those two repos are pushed, the script should run green start-to-finish (every component is already proven). Want me to add the local-clone dev mode to the test so you can iterate without pushing each time, or leave it fetching from GitHub like the other tests?
