Description

Adds a non-interactive mode to appsmithctl restore so instance restores can run unattended in CI/CD pipelines — requested by a customer for automated disaster recovery.

Linear: https://linear.app/appsmith/issue/APP-15482

New surface:

appsmithctl restore --backup-file=<name> [--non-interactive] [--force]
  • --backup-file=<name> — selects a backup by file name (as shown in the interactive listing), skipping the index prompt. Values containing path separators are rejected; the name must match an actual archive in the backup directory.
  • --non-interactive — suppresses every prompt (parity with appsmithctl backup). Any input that would have been prompted for must come from a flag or env var, otherwise the command exits 1 with a message naming what is missing — before services are stopped or the database is touched.
  • --force — proceeds despite an Appsmith version mismatch between backup and instance (non-interactive mode only; the interactive Enter-to-continue prompt is unchanged). It bypasses only the version gate — missing/wrong passwords, unknown file names, and missing encryption keys still exit 1.
  • APPSMITH_BACKUP_ARCHIVE_PASSWORD — supplies the archive decryption password (single attempt). The password reaches openssl via the child process environment (-pass env:), never argv, so it is not visible in the process table. Verified compatible with archives encrypted by the existing backup flow (-k), via a real openssl round-trip.
  • Unencrypted archives restored non-interactively use the instance's existing APPSMITH_ENCRYPTION_PASSWORD/APPSMITH_ENCRYPTION_SALT; both are validated up-front (ensureEncryptionKeysPresent, exported and unit-tested), and the check runs again defensively at the point of use in restoreDockerEnvFile.

Hardening/fixes riding with the feature (same concern — the new env var and the restore flow):

  • A failed decryption used to exit 0; it now exits 1.
  • APPSMITH_BACKUP_ARCHIVE_PASSWORD= is stripped from the docker.env bundled into future backup archives (removeSensitiveEnvData), so an operator who wrongly persists the transient secret does not leak it into archives. The = suffix keeps APPSMITH_BACKUP_ARCHIVE_LIMIT intact.
  • run()'s failure path now logs to stderr.

Impact on existing instances

  • Fresh install: no change; all new behavior is opt-in via flags/env var.
  • Upgrade from default: no change to interactive restore, with one exception — if APPSMITH_BACKUP_ARCHIVE_PASSWORD is set in the environment, the interactive password prompt is skipped and the env value is used (single attempt).
  • Upgrade from customized: scripts that (incorrectly) relied on exit code 0 from a failed decryption will now see exit 1 — this was a bug fix; a failed restore should never report success.
  • Rollback: older images silently ignore the new flags (restore never rejected unknown args), so a pipeline built on --non-interactive will hang at an interactive prompt rather than fail loudly. Pipelines must pin an image version at or above this release.

Deliberate scope decisions

  • APPSMITH_BACKUP_ARCHIVE_PASSWORD is intentionally not added to .env.example, Helm values, or the Heroku README: it is a per-invocation CI secret, not instance configuration. Persisting it in docker.env is exactly the mistake the new strip-list entry guards against. It should be supplied ephemerally, e.g. docker exec -e APPSMITH_BACKUP_ARCHIVE_PASSWORD=... <container> appsmithctl restore ....
  • --force without --non-interactive is a no-op (the interactive version prompt still appears). Unattended use requires --non-interactive.
  • Non-interactive restore assumes same-instance encryption keys; restoring another instance's backup requires exporting that instance's APPSMITH_ENCRYPTION_PASSWORD/SALT into the environment first.
  • Restore is fail-fast, not atomic: all validation happens before any mutation, but a mongorestore failure mid-run still leaves a partially restored instance (pre-existing behavior, unchanged).
  • Restore-by-index and a positional restore <file> form are omitted (the issue allows "CLI flags and/or environment variables"; an index is racy in automation).
  • Follow-ups tracked separately: backup-side encryptBackupArchive still passes its password on the openssl argv (pre-existing, same fix pattern applies); non-interactive appsmithctl backup never encrypts, so a fully automated encrypted backup→restore pipeline needs a backup-side counterpart; run()-level orchestration tests.

Call sites checked

  • All six readlineSync.question sites in restore.ts are gated for non-interactive mode (backup index, decrypt password loop, both encryption-key prompt paths, version-mismatch confirm); the test suite's default readlineSync.question mock throws, so any reachable prompt fails CI.
  • openssl password sinks: restore's runDecryptCommand fixed here; backup's encryptBackupArchive deliberately deferred (follow-up above).
  • removeSensitiveEnvData is the only path that writes env content into archives; covered.

CE/EE note

restore.ts already diverges in EE (S3 archive support), so the hourly sync will conflict on this file. The EE-side end state is prepared on a branch (includes the S3-aware --backup-file handling and an EE-only correction of the version-mismatch message, which wrongly named the appsmith-ce image) and will be used as the source of truth when resolving the bot's sync PR.

Testing

  • New restore.test.ts (15 tests): --backup-file selection/unknown-name/path-guard, non-interactive-without-file failure, env-password decrypt (asserts password absent from argv and present in child env; single attempt on wrong password), non-interactive-without-env failure, interactive prompt regression tests, ensureEncryptionKeysPresent (3 cases), version gate (abort / --force / match).
  • Tests were verified red against the pre-fix source, and mutation-checked (each behavior individually neutered kills its own tests).
  • Full src/ctl jest suite: 54/54 pass; eslint and tsc --noEmit clean.
  • Real openssl round-trip: archive encrypted with -k decrypts with -pass env:.
  • In-container end-to-end smoke test against appsmith/appsmith-ce:release with this branch's ctl bundle: 10 scenarios, all passing — full results in this comment.

Summary by CodeRabbit

  • New Features

    • Added non-interactive restore support with explicit backup-file selection.
    • Added optional force restore for version mismatches.
    • Added support for archive passwords supplied through environment settings.
    • Added validation for encryption keys, backup files, and archive decryption.
  • Bug Fixes

    • Sensitive archive passwords are no longer included in exported environment files.
    • Restore errors now fail clearly and return an appropriate error status.
  • Tests

    • Expanded coverage for backup selection, decryption, encryption validation, and restore compatibility.

Adds --backup-file=<name>, --non-interactive, and --force flags to
`appsmithctl restore`, plus the APPSMITH_BACKUP_ARCHIVE_PASSWORD env var
for archive decryption, so restores can run unattended in CI/CD
pipelines (APP-15482).

In non-interactive mode every prompt is replaced by a flag/env input;
anything missing exits 1 before services are stopped or the database is
touched. A version mismatch aborts unless --force is passed. The
decryption password reaches openssl via the child environment instead
of argv, a failed decryption now exits 1 (was 0), --backup-file values
containing path separators are rejected, and
APPSMITH_BACKUP_ARCHIVE_PASSWORD= is stripped from the docker.env
bundled into backup archives.

Walkthrough

Restore now supports non-interactive backup selection, archive decryption through environment variables, encryption-key validation, forced version mismatches, and error logging. Backup environment exports also remove the archive password.

Changes

Backup and restore controls

Layer / File(s) Summary
Archive password sanitization
app/client/packages/rts/src/ctl/backup/links/EnvFileLink.ts, app/client/packages/rts/src/ctl/backup/backup.test.ts
Environment exports remove APPSMITH_BACKUP_ARCHIVE_PASSWORD while preserving other backup settings. Tests cover this behavior.
Restore input and archive decryption
app/client/packages/rts/src/ctl/restore.ts
Restore validates --backup-file, detects --non-interactive, and passes archive passwords to OpenSSL through the child-process environment.
Restore validation and execution
app/client/packages/rts/src/ctl/restore.ts, app/client/packages/rts/src/ctl/restore.test.ts
Non-interactive restores validate encryption keys, require --force for version mismatches, handle decryption failures, and log errors with console.error. Tests cover interactive and non-interactive paths.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to e5e4b

Non-interactive restore supports archive passwords through an environment variable, but an explicitly configured empty password is still treated as missing, which can break affected automation before restoration begins. The PR is otherwise mergeable with explicit owner awareness or follow-up for this bounded edge case.

…up docker.env

Review follow-up on #42147: the strip test only checked that the password
value was gone; an empty-valued APPSMITH_BACKUP_ARCHIVE_PASSWORD= line would
have passed. Assert the key is absent too.

In-container smoke test — results

Ran against appsmith/appsmith-ce:release with this branch's ctl bundle (built via rts/build.js) overlaid at /opt/appsmith/rts/bundle/ctl/index.js. All docker exec invocations are genuinely non-TTY. Backup created in-container with appsmithctl backup --non-interactive; the encrypted variant was produced with the same openssl parameters the interactive backup uses (-k).

# Scenario Expected Result
1 restore --non-interactive (no file) exit 1, names --backup-file, no prompt/hang ✅ exit 1
2 --backup-file=nope.tar.gz exit 1, names file and backup dir ✅ exit 1
3 Unencrypted archive, keys in env exit 0, full restore ✅ exit 0 — 199 docs restored, docker.env written from env keys, git-storage restored, 7/7 services running after
4 Encrypted archive, no env password exit 1, "set APPSMITH_BACKUP_ARCHIVE_PASSWORD" ✅ exit 1
5 Encrypted archive, wrong env password exit 1, single attempt, decrypt-failure message ✅ exit 1
6 Encrypted archive, correct env password exit 0, full restore, decrypted intermediate cleaned up ✅ exit 0
7 Version mismatch (manifest tampered to v0.0.1-smoke), no --force exit 1, message points at --force, instance untouched ✅ exit 1
8 Same archive with --force exit 0, full restore, services running ✅ exit 0
9 --backup-file=../../../etc/passwd exit 1, path rejected ✅ exit 1
10 Missing APPSMITH_ENCRYPTION_PASSWORD/SALT, unencrypted archive exit 1 before services are stopped ✅ exit 1 — supervisord showed backend/rts "already started", i.e. never stopped

Row 10 happened organically and is worth a note: a hand-encrypted archive (unlike a real appsmithctl backup encrypted archive) does not carry encryption keys in its bundled docker.env, so restoring it leaves the instance keyless — the next unencrypted restore then fails the up-front key check exactly as designed, without touching services. Real encrypted backups embed the keys, so this only affects manually-encrypted archives; the fail-fast behavior is the designed safety net for it.
