sec(cli): remove the minted GCP service-account key after upload - #2112
Conversation
The GCP setup wizard wrote a never-expiring service-account key to ~/cudly-gcp-key.json and left it there after uploading it to Secrets Manager, where backups and file sync pick it up. The key is now written 0600 into a private 0700 os.MkdirTemp directory and removed (file and directory) after the upload succeeds and on every error path. A removal failure is returned, not ignored. An operator- supplied --credentials-file is never deleted. The AWS config now loads before the wizard runs, so a config error cannot strand a minted key. Closes #1947

in the wizard flow to include the existing remote-key deletion warning when
credential loading fails, while preserving the local-file cleanup and returned
error behavior.
- Line 189: Update the error message in the minted-key upload failure path to
include `creds.PrivateKeyID` and `creds.ClientEmail` as the key ID and
service-account argument in the `gcloud iam service-accounts keys delete`
command, so the command can be run to revoke the active key.

Install the non-empty directory from the storage callback.
A directory installed before uploadGCPCredentialsFile runs makes os.ReadFile fail, so the test does not reach credential storage. Install it in store.updateSecretFunc after the mock stores the credentials. The non-empty directory then makes os.Remove fail regardless of process privileges. Keep the existing assertion and mintTestGCPKey teardown.

A key minted by the configure-gcp wizard stayed active in GCP when the Secrets Manager upload (or parsing of the minted file) failed, and the error named no key ID. The wizard now threads the IAM key resource name returned by CreateKey through to the upload, and on any upload failure deletes the key via gcpKeyProvisioner.DeleteKey on a fresh context. If that delete fails too, the error names the key and prints the exact gcloud iam service-accounts keys delete command. The upload also runs under signal.NotifyContext, so SIGINT/SIGTERM cancels the Secrets Manager call and both the local and remote cleanup run instead of the process being killed. The signal scope covers only the upload, so Ctrl-C at the wizard's stdin prompts still exits.

Coordination: this session is implementing the independently reproduced SIGINT/SIGTERM leak described in comment 5880286762. The current merge-from-main head 770ad34 retains that defect. Follow-up verification exercises actual runConfigureGCP with local IAM/Secrets Manager fixtures, a saturated stdout pipe, and both signals. It will preserve this branch's history and be published only after independent review and a fresh remote-head check. Please keep this PR open until that blocker is resolved. |

Temporarily marked draft to prevent a stale background merge script from merging this PR while the independently reproduced SIGINT/SIGTERM credential leak remains. The merge-from-main update does not fix the leak. A minimal follow-up with real-command signal regression tests is implemented locally and undergoing independent review. This session will restore ready status after the corrected final HEAD passes review and verification. See comments 5880286762 and 5880693520 for evidence and coordination. |

Independent adversarial review (Opus 5.5), 2 passes, final head 238844f: MERGE. The minted GCP key is written 0600 in a MkdirTemp 0700 dir with O_EXCL and removed on every path. Any failure after minting (bad file, upload error, interrupt) deletes the key in GCP on a fresh 60s context, and success never deletes it. If the remote delete fails, the error prints the gcloud delete command with the key ID and SA email only (tested for no key material). SIGINT is caught only during the upload. Removing the delete fails 4 tests. 896 tests pass, golangci-lint v2.10.1 clean; CI green. Test-hardening follow-up filed. (branch updated with main; reviewed changes unchanged) |

Summary
cudly configure gcpStep 5 minted a never-expiring service-account key, wrote it to~/cudly-gcp-key.json, uploaded it to Secrets Manager, and left the plaintext key in the home directory, where backups and Dropbox/iCloud sync pick it up.Root cause
Nothing owned the minted file after
storeGCPCredentials:runConfigureGCPended at the success message, and the key path was a fixed file in$HOME.Fix
gcpStepCreateKeywrites the key (stillO_EXCL, 0600) into a fresh 0700os.MkdirTempdirectory (newMintedGCPKeyPath).uploadGCPCredentialsFileloads and uploads the file; when the wizard minted it, adeferremoves the file and its directory on success and on every error path (parse failure, upload failure). A removal failure is joined into the returned error, not ignored. The skip/unknown-choice and key-creation-failure paths ingcpStepCreateKeyalso remove the temp dir.--credentials-file(or prompted path) is never deleted.gcpKeyProvisioner.DeleteKeyon a fresh 60s context, so a canceled parent context can't skip it. The key resource name comes from the IAMCreateKeyresponse and is threaded throughgcpStepCreateKey/runGCPSetupCommands/getGCPCredentialsFilePath, so it is known even when the minted file can't be parsed. If the remote delete also fails, the error names the key ID and SA email (never key material) and prints the exactgcloud iam service-accounts keys delete <id> --iam-account=<sa>command.signal.NotifyContext(ctx, os.Interrupt, syscall.SIGTERM), so SIGINT/SIGTERM cancels the Secrets Manager call and both the local and remote cleanup run. The signal scope covers only the upload, so Ctrl-C at the wizard's stdin prompts still exits the process.Keeping the key purely in memory would be possible (Secrets Manager takes a string), but it needs the create/parse/upload flow reworked across the wizard; the temp-file approach keeps the existing reserve/mint/rollback flow in
writeServiceAccountKeyand its tests unchanged.Regression test
cmd/configure_gcp_test.go,TestUploadGCPCredentialsFile_*: mints a key through the realwriteServiceAccountKeywith a mocked IAM provisioner, asserts the file is 0600 and its dir 0700, then uploads through a mockSecretsStoreand asserts both file and dir are gone after a successful upload, a failed upload and a parse failure. Also covers the removal-failure error and that an operator file is kept. Remote cleanup (second commit): an upload failure callsDeleteKeywith the minted key name; a parse failure also deletes it; aDeleteKeyfailure yields the gcloud command in the error with no key material; a canceled upload context still runs the delete on a live context; success and operator-supplied files never delete the remote key. No real GCP or AWS calls.Proof it fails pre-fix: on the parent commit the tests don't compile (
undefined: newMintedGCPKeyPath); with the cleanupdeferdisabled, the 4 cleanup tests fail (--- FAIL: ...MintedKeyRemovedAfterSuccess,...AfterUploadFailure,...AfterParseFailure,...RemovalFailureReported). With the remote delete call removed from the uploaddefer, 4 tests fail (UploadFailureDeletesRemoteKey,RemoteDeleteFailureNamesGcloudCommand,CanceledContextStillCleansUp,ParseFailureDeletesRemoteKey).Verification
