From 64246a66158724862c3b5d8652fb0434a4f1575c Mon Sep 17 00:00:00 2001 From: Dan Date: Tue, 21 Oct 2025 21:32:23 -0700 Subject: [PATCH] Deploy Generation 31 with sops-nix secrets management Successfully deployed ops-jrz1 Matrix platform to production VPS using extracted modules from ops-base. Validated deployment workflow following ops-base best practices: boot -> reboot -> verify. Changes: - Pin sops-nix to June 2024 version for nixpkgs 24.05 compatibility - Configure sops secrets for Matrix registration token and ACME email - Add encrypted secrets.yaml (safe to commit, encrypted with age) - Document deployment process and lessons learned All services verified running: - Matrix homeserver (matrix-continuwuity): conduwuit 0.5.0-rc.8 - nginx: Proxying Matrix and Forgejo - PostgreSQL 15.10: Database services - Forgejo 7.0.12: Git platform Generated with Claude Code Co-Authored-By: Claude --- ...m-testing-vps-deployment-package-fixes.org | 528 ++++++++++++++++++ .../2025-10-22-deployment-generation-31.md | 128 +++++ flake.lock | 34 +- flake.nix | 2 +- hosts/ops-jrz1.nix | 15 + secrets/secrets.yaml | 28 + 6 files changed, 726 insertions(+), 9 deletions(-) create mode 100644 docs/worklogs/2025-10-21-ops-jrz1-vm-testing-vps-deployment-package-fixes.org create mode 100644 docs/worklogs/2025-10-22-deployment-generation-31.md create mode 100644 secrets/secrets.yaml diff --git a/docs/worklogs/2025-10-21-ops-jrz1-vm-testing-vps-deployment-package-fixes.org b/docs/worklogs/2025-10-21-ops-jrz1-vm-testing-vps-deployment-package-fixes.org new file mode 100644 index 0000000..5645eed --- /dev/null +++ b/docs/worklogs/2025-10-21-ops-jrz1-vm-testing-vps-deployment-package-fixes.org @@ -0,0 +1,528 @@ +#+TITLE: ops-jrz1 VM Testing Workflow and VPS Deployment with Package Resolution Fixes +#+DATE: 2025-10-21 +#+KEYWORDS: nixos, vps, deployment, vm-testing, nixpkgs-unstable, package-resolution, matrix, vultr +#+COMMITS: 6 +#+COMPRESSION_STATUS: uncompressed + +* Session Summary +** Date: 2025-10-21 (Day 9 of ops-jrz1 project - Continuation session) +** Focus Area: VM testing workflow implementation, package resolution debugging, and production VPS deployment + +This session focused on implementing VM testing as a pre-deployment validation step, discovering and fixing critical package availability issues, and deploying the ops-jrz1 configuration to the production VPS.

Build locally, deploy remotely - Test build before touching production + 2. Build & deploy on VPS directly - Simpler, faster with VPS cache + 3. Safe testing flow - Build locally, deploy with nixos-rebuild boot, reboot to test +- Rationale: + - VPS is running live production services (Matrix homeserver with 2 weeks uptime) + - nixos-rebuild boot doesn't activate until reboot (safer than switch) + - Previous generation available in GRUB for rollback if needed + - Matches historical deployment pattern from ops-base worklogs +- Impact: Deployment approach minimizes risk to running production services + +** Decision 2: Fix Module Package References to Use pkgs-unstable (Option 2) +- Context: VM build failed with "attribute 'mautrix-slack' missing" error +- Problem: ops-jrz1 uses nixpkgs 24.05 stable for base, but mautrix packages only in unstable +- Options considered: + 1. Use unstable for everything - Affects entire system unnecessarily + 2. Fix modules to use pkgs-unstable parameter - Precise scoping, self-documenting + 3. Override per configuration - Repetitive, harder to maintain +- Rationale: + - Keeps stable base system (NixOS core, security updates) + - Only Matrix packages from unstable (under active development) + - Self-documenting (modules explicitly show they need unstable) + - Precise scoping (doesn't affect entire system stability) + - User feedback validated this was proper approach vs Option 1 +- Impact: Enables building while maintaining system stability with hybrid approach + +** Decision 3: Permit olm-3.2.16 Despite Security Warnings +- Context: Deprecated olm library with known CVEs (CVE-2024-45191, CVE-2024-45192, CVE-2024-45193) +- Problem: Required by all mautrix bridges, no alternatives currently available +- Rationale: + - Matrix bridges require olm for end-to-end encryption + - Upstream Matrix.org confirms exploits unlikely in practical conditions + - Vulnerability is cryptography library side-channel issues, not network exploitable + - Documented explicitly in configuration for future review + - Acceptable risk for bridge functionality until alternatives available +- Impact: Enables Matrix bridge functionality with informed security trade-off + +** Decision 4: Enable Services in Production Host Configuration +- Context: hosts/ops-jrz1.nix had placeholder disabled service configs +- Problem: Need actual service configuration for VPS deployment +- Rationale: + - VPS already running Matrix homeserver and Forgejo from ops-base + - Continuity requires same services enabled in ops-jrz1 + - Configuration from SSH inspection: clarun.xyz domain, delpadtech workspace + - Matches running system to avoid service disruption +- Impact: Seamless transition from ops-base to ops-jrz1 configuration + +** Decision 5: Use dlei@duck.com for ACME Email +- Context: Let's Encrypt requires email for certificate expiration notices +- Rationale: + - Historical pattern from ops-base worklog (2025-10-01-vultr-vps-https-lets-encrypt-setup.org) + - Email not publicly exposed, only for CA notifications + - Matches previous VPS deployment pattern +- Impact: Enables automatic HTTPS certificate management + +* Problems & Solutions + +| Problem | Solution | Learning | +|---------|----------|----------| +| VM build failed: "attribute 'mautrix-slack' missing" at modules/mautrix-slack.nix:58 | 1. Identified root cause: pkgs from nixpkgs 24.05 stable lacks mautrix packages
2. Updated module function signatures to accept pkgs-unstable parameter
3. Changed package defaults from pkgs.* to pkgs-unstable.*
4. Fixed 5 references across 4 modules | NixOS modules need explicit parameters passed via specialArgs. Package availability differs significantly between stable and unstable channels. Module option defaults must use the correct package set. | +| Module function signatures missing pkgs-unstable parameter | Added pkgs-unstable to function parameters in all 4 modules: mautrix-slack.nix, mautrix-whatsapp.nix, mautrix-gmessages.nix, dev-services.nix | Module parameters must be explicitly declared in function signature before use. Nix will error on undefined variables. | +| VM flake check failed: "Package 'olm-3.2.16' is marked as insecure" | 1. Added permittedInsecurePackages to VM flake.nix pkgs-unstable config
2. Added permittedInsecurePackages to hosts/ops-jrz1-vm.nix nixpkgs.config
3. Documented security trade-off with explicit comments | Insecure package permissions must be set both in pkgs-unstable import (flake.nix) AND in nixpkgs.config (host config). Different scopes require different permission locations. | +| Production build failed with same olm error | Added permittedInsecurePackages to production flake.nix pkgs-unstable config AND configuration.nix | Same permission needed in both VM and production. Permissions in specialArgs pkgs-unstable don't automatically apply to base pkgs. | +| ACME configuration missing for production | Added security.acme block to configuration.nix with acceptTerms and defaults.email from ops-base pattern | ACME requires explicit terms acceptance and email configuration. Pattern matches historical deployment from ops-base/docs/worklogs/2025-10-01-vultr-vps-https-lets-encrypt-setup.org | +| VM testing attempted GUI console (qemu-kvm symbol lookup error for pipewire) | Recognized GUI not needed for validation - build success validates package availability | VM runtime testing not required when goal is package resolution validation. Successful build proves all packages resolve correctly. GUI errors in QEMU don't affect headless VPS deployment. | + +* Technical Details + +** Code Changes +- Total files modified/created: 9 +- Commits made: 6 +- Key files changed: + - `flake.nix` - Added ops-jrz1-vm configuration, configured pkgs-unstable with olm permission for both VM and production + - `configuration.nix` - Updated boot loader (/dev/vda), network (ens3), added ACME config, added olm permission + - `hosts/ops-jrz1-vm.nix` - Created VM testing config with services enabled, olm permission + - `hosts/ops-jrz1.nix` - Updated from placeholder to production config (clarun.xyz, delpadtech) + - `hardware-configuration.nix` - Created from VPS nixos-generate-config output + - `modules/mautrix-slack.nix` - Added pkgs-unstable parameter, changed default package + - `modules/mautrix-whatsapp.nix` - Added pkgs-unstable parameter, changed default package + - `modules/mautrix-gmessages.nix` - Added pkgs-unstable parameter, changed default package + - `modules/dev-services.nix` - Added pkgs-unstable parameter, changed 2 package references + +** Commit History +``` +40e5501 Fix: Add olm permission to pkgs-unstable in production config +0cbbb19 Allow olm-3.2.16 for mautrix bridges in production +982d288 Add ACME configuration for Let's Encrypt certificates +413a44a Configure ops-jrz1 for production deployment to Vultr VPS +4c38331 Fix Matrix package references to use nixpkgs-unstable +b8e00b7 Add VM testing configuration for pre-deployment validation +``` + +** Commands Used + +### Package reference fixes +```bash +# Find all package references that need updating +rg "pkgs\.(mautrix|matrix-continuwuity)" modules/ + +# Test local build after fixes +nix build .#nixosConfigurations.ops-jrz1.config.system.build.toplevel -L + +# Validate flake syntax +nix flake check +``` + +### VPS investigation +```bash +# Test SSH connectivity and check running services +ssh root@45.77.205.49 "hostname && nixos-version" +ssh root@45.77.205.49 'systemctl list-units --type=service --state=running | grep -E "(matrix|mautrix|continuwuit)"' + +# Retrieve hardware configuration +ssh root@45.77.205.49 'cat /etc/nixos/hardware-configuration.nix' + +# Check secrets setup +ssh root@45.77.205.49 'ls -la /run/secrets/' +``` + +### Deployment commands +```bash +# Sync repository to VPS +rsync -avz --exclude '.git' --exclude 'result' --exclude 'result-*' --exclude '*.qcow2' --exclude '.specify' \ + /home/dan/proj/ops-jrz1/ root@45.77.205.49:/root/ops-jrz1/ + +# Deploy using safe boot method (doesn't activate until reboot) +ssh root@45.77.205.49 'cd /root/ops-jrz1 && nixos-rebuild boot --flake .#ops-jrz1' + +# After reboot, switch would be: +# ssh root@45.77.205.49 'nixos-rebuild switch --flake .#ops-jrz1' +``` + +## Architecture Notes + +### Hybrid nixpkgs Approach (Stable Base + Unstable Overlay) +The configuration uses a two-tier package strategy: +- **Base system (pkgs)**: nixpkgs 24.05 stable for core NixOS, systemd, security +- **Matrix packages (pkgs-unstable)**: nixpkgs-unstable for Matrix ecosystem + +Implemented via specialArgs in flake.nix: +```nix +specialArgs = { + pkgs-unstable = import nixpkgs-unstable { + system = "x86_64-linux"; + config = { + allowUnfree = true; + permittedInsecurePackages = ["olm-3.2.16"]; + }; + }; +}; +``` + +Modules access via function parameters: +```nix +{ config, pkgs, pkgs-unstable, lib, ... }: +``` + +### Package Availability Differences +**nixpkgs 24.05 stable does NOT include:** +- mautrix-slack +- mautrix-whatsapp +- mautrix-gmessages +- matrix-continuwuity (Conduwuit Matrix homeserver) + +**nixpkgs-unstable includes all of the above** because Matrix ecosystem under active development. + +### ACME Certificate Management Pattern +From ops-base historical deployment (2025-10-01): +- security.acme.acceptTerms = true (required) +- security.acme.defaults.email for notifications +- nginx virtualHosts with enableACME = true and forceSSL = true +- HTTP-01 challenge (requires port 80 open) +- Automatic certificate renewal 30 days before expiration + +### VM Testing Workflow +Purpose: Catch deployment issues before they affect production + +**Approach:** +1.
