Summary

  • Fix stray + before set -euo pipefail that broke the script on the first line
  • Allow no-argument invocation under set -u (BACKUP_FOLDER="${1:-}") so the interactive prompt is reachable
  • Don't exit under pipefail when no compose project matches, and recognize running(N) statuses when checking whether the airgapped instance is running
  • Fix unquoted glob in the backup extraction loop ("$BACKUP_FOLDER"/*.tar.gz)
  • Rename extracted backup dirs (pgdata/redisdata/uploads/rabbitmq_data) to the volume paths the airgapped docker-compose expects (db/redis/minio/uploads/mq), then fix ownership once at the end
  • Update ASCII header to the current logo

This keeps the shipped script in sync with the version now embedded in the developer docs (makeplane/developer-docs#321).

Test plan

  • bash -n syntax check passes (verified locally)
  • Run a Community → Airgapped migration: setup.sh backup on CE, transfer, sudo bash restore-airgapped.sh ./<backup-dir>, verify data dirs land at data/db, data/redis, data/minio/uploads, data/mq and the instance starts
  • Run script with no args — verify it prompts instead of exiting with "unbound variable"
  • Run script while the airgapped instance is up — verify it refuses to restore

🧙 Built with WOZCODE

Summary by CodeRabbit

  • Bug Fixes
    • Improved air-gapped backup restoration when no backup folder is specified.
    • Restores multiple backup archives more reliably and places database, cache, upload, and messaging data correctly.
    • Preserves existing data until replacement succeeds and improves recovery if restoration is interrupted.
    • Better handles unavailable service status details and recognizes statuses that begin with “running.”
    • Applies data permissions consistently after extraction.
    • Provides clearer guidance when no backup files are found.

- Fix stray "+" before set -euo pipefail
- Allow no-argument invocation under set -u (BACKUP_FOLDER="${1:-}")
- Don't exit under pipefail when no compose project matches; recognize
  "running(N)" statuses when checking if the instance is running
- Fix unquoted glob in the backup extraction loop
- Rename extracted dirs (pgdata/redisdata/uploads/rabbitmq_data) to the
  volume paths the airgapped docker-compose expects (db/redis/minio/uploads/mq)
- Update ASCII header to the current logo

📝 Walkthrough

Walkthrough

The air-gapped restore script updates backup input handling, compose status checks, and archive replacement. Compose files and test documentation also update the MinIO image reference to docker.io/pgsty/minio:RELEASE.2026-08-04T00-00-00Z.

Changes

Air-gapped restore flow

Layer / File(s) Summary
Restore setup and status handling
deployments/cli/community/restore-airgapped.sh
The script defaults the backup folder to an empty string when no argument is provided. It prints usage when no backup files exist and reports compose query failures. The running-state check accepts statuses that start with running.
Archive extraction and directory replacement
deployments/cli/community/restore-airgapped.sh
The restore loop extracts archives without first deleting target directories. It uses replaceDir to replace mapped directories and applies ownership once across the data directory.

MinIO image updates

Layer / File(s) Summary
MinIO image references
deployments/cli/community/docker-compose.yml, docker-compose-local.yml, docker-compose-test.yml, docker-compose.yml, apps/api/tests/RUNNING_TESTS.md
The compose service definitions and test service table use docker.io/pgsty/minio:RELEASE.2026-08-04T00-00-00Z instead of the previous Quay image reference.

Merge Risk: 🟡 Moderate · up to 24e90

A terminated restore can leave an existing data volume unavailable. Close that signal-handling gap before merging; confirm image provenance before relying on the proposed security update.

Security Architecture Review

Security architecture risk: 🟠 High · up to 24e90

The object-store image change affects several deployments and carries a reported high-impact authorization issue. The restore also changes how database and file data are replaced; interruption can leave data missing from its expected path or leave volumes at different restore stages.

Retained concerns

  • High · security · inferred: The replacement object-store image changes the runtime responsible for enforcing S3 authorization across four Compose deployments. A retained Security finding reports an authorization bypass associated with this image change; unchanged Compose credential wiring does not establish equivalent authorization inside the image. Exploit scope depends on effective endpoint access, object versioning, and delegated credentials.
  • Medium · reliability · inferred: The new volume replacement sequence does not preserve a recoverable, consistent restore state across interruption or failure: an interruption between moving an existing destination aside and installing its trap can strand it under a process-specific name, while a later volume failure does not undo earlier replacements. This threatens the integrity and availability of restored database and object data.
Security review details

Security Blast Radius

  • inferred — The affected authorization boundary is each deployment's MinIO-backed object store, not a demonstrated repository-wide bypass of the API. The new image is selected by local, test, main, and community Compose consumers; only the local service's host-published S3 and console ports were established directly here.

Security Findings and Attack Paths

  • inferred — The retained Security finding reports an externally reachable, high-impact authorization bypass tied to the new image reference. Its effective object-version attack path is conditional on the deployed image behavior, reachable S3 endpoint, versioned objects, and applicable delegated credentials; those deployment conditions are not established by the Compose files.

Trust Boundaries and Controls

  • observed — The image publisher changes while Compose continues to supply root credentials and invoke the configured server commands. The unchanged configuration is counterevidence to a newly declared unauthenticated entrypoint or port, but cannot verify enforcement inside the replacement image.

Resilience and Maintainability Implications

  • inferred — Restore interruption can strand an existing data directory outside its expected path; later failures can leave database and upload directories at different restore stages. The source establishes an integrity and recovery risk, not a demonstrated cross-tenant disclosure.

Hardening Proposals

  • proposed — Verify the replacement image's provenance and object-version authorization behavior against the intended S3 policy before rollout; record an immutable image identity for the deployments that consume it.
  • proposed — Make restore recovery explicit across all volumes, including interruption before a trap is active, repeated execution, and an interrupted replacement after earlier volumes have committed.

Pull request overview

This PR hardens the Community restore-airgapped.sh migration script used under deployments/cli/community, primarily to make it robust under set -euo pipefail and to correctly map restored backup directories to the airgapped docker-compose volume layout.

Changes:

  • Fixes strict-mode breakages (stray +, no-arg invocation under set -u, and more tolerant “is running” detection).
  • Improves backup extraction handling (quoted glob, directory renames to expected volume paths, consolidated ownership fix).
  • Updates the script header/logo output.

- Around line 127-128: The restore flow around the directory replacements must
preserve existing data until each extracted directory is successfully installed.
Replace the rm -rf followed by mv operations for db, and the analogous
directories at the other replacement sites, with staged swaps that retain the
previous destination for rollback; remove the old directory only after the
replacement succeeds, restoring it if the move fails or is interrupted.
- Line 83: Update the dockerServiceStatus pipeline in the restore script so
failures from $COMPOSE_CMD ls propagate instead of being converted to an empty
status; tolerate only grep’s no-match result, while preserving the existing
running-status extraction used by the subsequent service-state check.

- fail loudly when compose status query fails instead of treating it as stopped
- use if ! tar guard since $? check was dead under set -e
- clean stale extracted dirs before re-extraction to avoid merged restores
- stage directory swaps with rollback so old data survives a failed move
- remove unreachable else branch with misleading error message

Trap INT/TERM/HUP between the two mv operations in replaceDir so the
volume path is never left missing mid-swap.
