* 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. The work validated the VM testing workflow by catching deployment-breaking issues before they could affect production.
|
||||
|
||||
* Accomplishments
|
||||
- [X] Researched ops-base deployment patterns and historical approaches from worklogs
|
||||
- [X] Fixed VM configuration build (package resolution for mautrix bridges)
|
||||
- [X] Validated production configuration builds successfully
|
||||
- [X] Discovered and fixed nixpkgs stable vs unstable package availability mismatch
|
||||
- [X] Updated module function signatures to accept pkgs-unstable parameter
|
||||
- [X] Configured ACME (Let's Encrypt) for production deployment
|
||||
- [X] Retrieved hardware-configuration.nix from running VPS
|
||||
- [X] Configured production host (hosts/ops-jrz1.nix) with clarun.xyz domain
|
||||
- [X] Deployed to VPS using nixos-rebuild boot (safe deployment method)
|
||||
- [X] Created 6 commits documenting VM setup, package fixes, and deployment config
|
||||
- [X] Validated VM testing workflow catches deployment issues early
|
||||
|
||||
* Key Decisions
|
||||
|
||||
** Decision 1: Use VM Testing Before VPS Deployment (Option 3 from ops-base patterns)
|
||||
- Context: User provided VPS IP (45.77.205.49) and asked about deployment approach
|
||||
- Options considered:
|
||||
1. 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<br>2. Updated module function signatures to accept pkgs-unstable parameter<br>3. Changed package defaults from pkgs.* to pkgs-unstable.*<br>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<br>2. Added permittedInsecurePackages to hosts/ops-jrz1-vm.nix nixpkgs.config<br>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. |

||||
# 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. Create ops-jrz1-vm configuration with services enabled (test-like)
|
||||
2. Build VM: `nix build .#nixosConfigurations.ops-jrz1-vm.config.system.build.vm`
|
||||
3. Successful build validates package resolution, module evaluation, secrets structure
|
||||
4. Runtime testing optional (GUI limitations in some environments)
|
||||
|
||||
**Benefits demonstrated:**
|
||||
- Caught package availability mismatch before VPS deployment
|
||||
- Validated olm permission configuration needed
|
||||
- Verified module function signatures
|
||||
- Tested configuration without touching production
|
||||
|
||||
### VPS Current State (Before Deployment)
|
||||
- Hostname: jrz1
|
||||
- NixOS: 25.11 unstable
|
||||
- Running services: Matrix (continuwuity), mautrix-slack, Forgejo, PostgreSQL, nginx, fail2ban, netdata
|
||||
- Uptime: 2 weeks (Matrix homeserver stable)
|
||||
- Secrets: /run/secrets/matrix-registration-token, /run/secrets/acme-email
|
||||
- Domain: clarun.xyz
|
||||
- Previous config: ops-base (unknown location on VPS)
|
||||
|
||||
* Process and Workflow
|
||||
|
||||
** What Worked Well
|
||||
- VM testing workflow caught critical deployment issue before production
|
||||
- Historical worklog research provided proven deployment patterns
|
||||
- Incremental fixes (module by module) easier to debug than batch changes
|
||||
- Local build testing before VPS deployment validated configuration
|
||||
- SSH investigation of running VPS informed configuration decisions
|
||||
- User feedback loop corrected initial weak reasoning (Option 1 vs Option 2)
|
||||
- Git commits at logical checkpoints preserved intermediate working states
|
||||
|
||||
** What Was Challenging
|
||||
- Initial attempt to fix package references forgot to add pkgs-unstable to function signatures
|
||||
- olm permission needed in BOTH flake.nix specialArgs AND configuration.nix
|
||||
- Understanding that pkgs-unstable permissions don't automatically apply to pkgs
|
||||
- VM GUI testing didn't work in terminal environment (but wasn't needed)
|
||||
- Deployment still running at end of session (long download time)
|
||||
- Multiple rounds of rsync + build to iterate on fixes
|
||||
|
||||
** What Would Have Helped
|
||||
- Earlier recognition that build success validates package resolution (VM runtime not needed)
|
||||
- Understanding that permittedInsecurePackages needs to be in multiple locations
|
||||
- Clearer mental model of flake specialArgs vs nixpkgs.config scoping
|
||||
|
||||
* Learning and Insights
|
||||
|
||||
** Technical Insights
|
||||
- NixOS modules require explicit function parameters; specialArgs only provides them at module boundary
|
||||
- Package availability differs dramatically between stable (24.05) and unstable channels
|
||||
- Matrix ecosystem packages rarely make it into stable due to rapid development pace
|
||||
- Insecure package permissions must be set in BOTH pkgs-unstable import AND nixpkgs.config
|
||||
- VM build success is sufficient validation for package resolution; runtime testing is optional
|
||||
- VM testing can run in environments without GUI (build-only validation)
|
||||
- nixos-rebuild boot is safer than switch for production deployments (activate on reboot)
|
||||
- GRUB generations provide rollback path if deployment breaks boot
|
||||
- ops-base worklogs contain valuable deployment patterns and historical decisions
|
||||
|
||||
** Process Insights
|
||||
- Research historical worklogs before choosing deployment approach
|
||||
- User feedback critical for correcting reasoning flaws (Option 1 vs 2 decision)
|
||||
- Incremental fixes with test builds catch issues early
|
||||
- Local build validation before VPS deployment prevents partial failures
|
||||
- SSH investigation of running system informs configuration accuracy
|
||||
- Git commits at working states enable bisecting issues
|
||||
- Background bash commands allow multitasking during long builds
|
||||
|
||||
** Architectural Insights
|
||||
- Hybrid stable+unstable approach balances system stability with package availability
|
||||
- Module function signatures make dependencies explicit and self-documenting
|
||||
- specialArgs provides clean dependency injection to NixOS modules
|
||||
- Package permissions have different scopes (import-time vs config-time)
|
||||
- VM configurations useful for validation even without runtime testing
|
||||
- Secrets already in place from ops-base (/run/secrets/) simplify migration
|
||||
- Hardware config from running system (nixos-generate-config) ensures boot compatibility
|
||||
|
||||
** Security Insights
|
||||
- olm library deprecation with CVEs is acceptable risk for Matrix bridge functionality
|
||||
- Upstream Matrix.org assessment: exploits unlikely in practical network conditions
|
||||
- Explicit documentation of security trade-offs critical for future review
|
||||
- Side-channel attacks in cryptography libraries different risk profile than network exploits
|
||||
- ACME email for Let's Encrypt notifications not publicly exposed
|
||||
- SSH key-based authentication maintained throughout deployment
|
||||
|
||||
* Context for Future Work
|
||||
|
||||
** Open Questions
|
||||
- Will the VPS deployment complete successfully? (still downloading packages at session end)
|
||||
- Will services remain running after reboot to new ops-jrz1 configuration?
|
||||
- Do Matrix bridges need additional configuration beyond module defaults?
|
||||
- Should we establish automated testing of VM builds in CI?
|
||||
- How to handle olm deprecation long-term? (wait for upstream alternatives)
|
||||
- Should we add monitoring for ACME certificate renewal failures?
|
||||
|
||||
** Next Steps
|
||||
- Wait for nixos-rebuild boot to complete on VPS
|
||||
- Reboot VPS to activate ops-jrz1 configuration
|
||||
- Verify all services start successfully (matrix-continuwuity, mautrix-slack, forgejo, postgresql, nginx)
|
||||
- Test HTTPS access to clarun.xyz and git.clarun.xyz
|
||||
- Confirm ACME certificates obtained from Let's Encrypt
|
||||
- Test Matrix homeserver functionality
|
||||
- Validate Slack bridge still working
|
||||
- Document any post-deployment issues or fixes needed
|
||||
- Create worklog for deployment completion session
|
||||
- Consider adding VM build to pre-commit hooks or CI

||||
** Technical Debt Identified
|
||||
- olm-3.2.16 deprecated with CVEs - need to monitor for alternatives
|
||||
- VM testing workflow not yet integrated into automated testing
|
||||
- No monitoring/alerting configured for ACME renewal failures
|
||||
- Deployment approach manual (rsync + ssh); could use deploy-rs or colmena
|
||||
- No rollback testing performed (trust in GRUB generations)
|
||||
- Documentation of VM testing workflow not yet written
|
||||
- No pre-commit hook to validate flake builds before commit
|
||||

* Raw Notes
|
||||
|
||||
## Session Flow Timeline
|
||||
|
||||
### Phase 1: Status Assessment and Planning (Start)
|
||||
- User asked about deployment next steps after previous session
|
||||
- I provided status summary: 53.4% MVP complete, 3+ phases done
|
||||
- User expressed interest in VM testing workflow: "I like VM Test First"
|
||||
- Goal: Make VM testing regular part of workflow for certain deploys
|
||||
|
||||
### Phase 2: VM Configuration Creation
|
||||
- Created hosts/ops-jrz1-vm.nix with VM-specific settings
|
||||
- Updated flake.nix to add ops-jrz1-vm configuration
|
||||
- Attempted VM build, discovered package availability error
|
||||
|
||||
### Phase 3: Package Resolution Debugging
|
||||
- Error: "attribute 'mautrix-slack' missing" at modules/mautrix-slack.nix:58
|
||||
- Root cause: pkgs from nixpkgs 24.05 stable lacks mautrix packages
|
||||
- Researched ops-base to understand their approach (uses unstable for everything)
|
||||
- Proposed Option 1: Use unstable everywhere
|
||||
- User feedback: "2 and 4 are the same reason and not a good one. 3. Simplicity isn't a reason if it potentially introduces future complexity. 1. is a good reason."
|
||||
- Revised to Option 2: Fix modules to use pkgs-unstable parameter
|
||||
|
||||
### Phase 4: Module Fixes Implementation
|
||||
- Updated 4 module function signatures to accept pkgs-unstable
|
||||
- Changed 5 package references from pkgs.* to pkgs-unstable.*
|
||||
- Discovered olm permission needed in multiple locations
|
||||
- Added permittedInsecurePackages to VM flake config
|
||||
- Added permittedInsecurePackages to VM host config
|
||||
- VM build succeeded!
|
||||
|
||||
### Phase 5: Production Configuration
|
||||
- User provided VPS IP: 45.77.205.49
|
||||
- User asked about deployment approach (local vs VPS build)
|
||||
- Researched ops-base deployment patterns from worklogs
|
||||
- Found historical use of nixos-rebuild boot (safe deployment)
|
||||
- User agreed: "I like the look of Option 3, a reboot is fine"
|
||||
|
||||
### Phase 6: VPS Investigation
|
||||
- SSH to VPS to check current state
|
||||
- Found: NixOS 25.11 unstable, Matrix + services running, 2 weeks uptime
|
||||
- Retrieved hardware-configuration.nix from VPS
|
||||
- Checked secrets: /run/secrets/matrix-registration-token exists
|
||||
- Found domain: clarun.xyz
|
||||
- No ops-base repo found on VPS (config location unknown)
|
||||
|
||||
### Phase 7: Production Config Updates
|
||||
- Created hardware-configuration.nix locally from VPS output
|
||||
- Updated configuration.nix: boot loader (/dev/vda), network (ens3), SSH keys, Nix flakes
|
||||
- Added ACME configuration (dlei@duck.com from ops-base pattern)
|
||||
- Updated hosts/ops-jrz1.nix: enabled services, clarun.xyz domain, delpadtech workspace
|
||||
- Added olm permission to production flake and configuration
|
||||
|
||||
### Phase 8: Production Build Testing
|
||||
- Built ops-jrz1 config locally to validate
|
||||
- Build succeeded - confirmed all package references working
|
||||
- Committed production configuration changes
|
||||
|
||||
### Phase 9: Deployment Initiation
|
||||
- Synced ops-jrz1 to VPS via rsync
|
||||
- Started nixos-rebuild boot on VPS (running in background)
|
||||
- Deployment downloading 786.52 MiB packages (still running at session end)
|
||||
|
||||
## Key Error Messages Encountered
|
||||
|
||||
### Package availability error
|
||||
```
|
||||
error: attribute 'mautrix-slack' missing
|
||||
at /nix/store/.../modules/mautrix-slack.nix:58:17:
|
||||
58| default = pkgs.mautrix-slack;
|
||||
```
|
||||
Solution: Change to `pkgs-unstable.mautrix-slack`
|
||||
|
||||
### Insecure package error
|
||||
```
|
||||
error: Package 'olm-3.2.16' in /nix/store/.../pkgs/by-name/ol/olm/package.nix:42 is marked as insecure, refusing to evaluate.
|
||||
|
||||
Known issues:
|
||||
- The libolm end‐to‐end encryption library used in many Matrix
|
||||
clients and Jitsi Meet has been deprecated upstream, and relies
|
||||
on a cryptography library that has known side‐channel issues...
|
||||
```
|
||||
Solution: Add to permittedInsecurePackages in both flake.nix pkgs-unstable config AND configuration.nix
|
||||
|
||||
### Module parameter undefined
|
||||
```
|
||||
error: undefined variable 'pkgs-unstable'
|
||||
at /nix/store/.../modules/mautrix-slack.nix:58:17:
|
||||
```
|
||||
Solution: Add pkgs-unstable to module function signature parameters

# Deployment: Generation 31 - Matrix Platform Migration
|
||||
**Date:** 2025-10-22
|
||||
**Status:** ✅ SUCCESS
|
||||
**Generation:** 31
|
||||
**Deployment Time:** ~5 minutes (build + reboot)
|
||||
|
||||
## Summary
|
||||
Successfully deployed ops-jrz1 Matrix platform using modules extracted from ops-base. This deployment established the foundation deployment pattern and validated sops-nix secrets management integration.
|
||||
|
||||
## Deployment Method
|
||||
Following ops-base best practices from worklog research:
|
||||
|
||||
```bash
|
||||
# 1. Build and install to boot (safe, rollback-friendly)
|
||||
rsync -avz --exclude '.git' --exclude 'result' /home/dan/proj/ops-jrz1/ root@45.77.205.49:/root/ops-jrz1/
|
||||
ssh root@45.77.205.49 'cd /root/ops-jrz1 && nixos-rebuild boot --flake .#ops-jrz1'
|
||||
|
||||
# 2. Reboot to test
|
||||
ssh root@45.77.205.49 'reboot'
|
||||
|
||||
# 3. Verify services after reboot (verified all running)
|
||||
ssh root@45.77.205.49 'systemctl status matrix-continuwuity nginx postgresql forgejo'
|
||||
|
||||
# 4. Test API endpoints
|
||||
curl http://45.77.205.49:8008/_matrix/client/versions
|
||||
```
|
||||
|
||||
## What Works ✅
|
||||
|
||||
### Core Infrastructure
|
||||
- **NixOS Generation 31** booted successfully
|
||||
- **sops-nix** decrypting secrets correctly using VPS SSH host key
|
||||
- **Age encryption** working with key: `age1vuxcwvdvzl2u7w6kudqvnnf45czrnhwv9aevjq9hyjjpa409jvkqhkz32q`
|
||||
|
||||
### Services Running
|
||||
- **Matrix Homeserver (matrix-continuwuity):** ✅ Running, API responding
|
||||
- Version: conduwuit 0.5.0-rc.8
|
||||
- Listening on: 127.0.0.1:8008
|
||||
- Database: RocksDB schema version 18
|
||||
- Registration enabled, federation disabled
|
||||
|
||||
- **nginx:** ✅ Running
|
||||
- Proxying to Matrix homeserver
|
||||
- ACME certificates configured for clarun.xyz and git.clarun.xyz
|
||||
- Note: WebDAV errors expected (legacy feature, can be removed)
|
||||
|
||||
- **PostgreSQL 15.10:** ✅ Running
|
||||
- Serving Forgejo database
|
||||
- Minor client disconnect logs normal (connection pooling)
|
||||
|
||||
- **Forgejo 7.0.12:** ✅ Running
|
||||
- Git service operational
|
||||
- Connected to PostgreSQL
|
||||
- Available at git.clarun.xyz
|
||||
|
||||
### Files Successfully Migrated
|
||||
- `.sops.yaml` - Encrypted secrets configuration
|
||||
- `secrets/secrets.yaml` - Encrypted secrets (committed to git, safe because encrypted)
|
||||
- All Matrix platform modules from ops-base
|
||||
|
||||
## Configuration Highlights
|
||||
|
||||
### sops-nix Setup
|
||||
Located in `hosts/ops-jrz1.nix:26-38`:
|
||||
```nix
|
||||
sops.defaultSopsFile = ../secrets/secrets.yaml;
|
||||
sops.age.sshKeyPaths = [ "/etc/ssh/ssh_host_ed25519_key" ];
|
||||
|
||||
sops.secrets.matrix-registration-token = {
|
||||
owner = "continuwuity";
|
||||
group = "continuwuity";
|
||||
mode = "0440";
|
||||
};
|
||||
|
||||
sops.secrets.acme-email = {
|
||||
owner = "root";
|
||||
mode = "0444";
|
||||
};
|
||||
```
|
||||
|
||||
### Version Compatibility
|
||||
Pinned sops-nix to avoid Go version mismatch (flake.nix:9):
|
||||
```nix
|
||||
sops-nix = {
|
||||
url = "github:Mic92/sops-nix/c2ea1186c0cbfa4d06d406ae50f3e4b085ddc9b3"; # June 2024 version
|
||||
inputs.nixpkgs.follows = "nixpkgs";
|
||||
};
|
||||
```
|
||||
|
||||
## Key Lessons from ops-base Research
|
||||
|
||||
### Deployment Pattern (Recommended)
|
||||
1. **`nixos-rebuild boot`** - Install to bootloader, don't activate yet
|
||||
2. **Reboot** - Test new configuration
|
||||
3. **Verify services** - Ensure everything works
|
||||
4. **`nixos-rebuild switch`** (optional) - Make current profile permanent
|
||||
|
||||
**Rollback:** If anything fails, select previous generation from GRUB or `nixos-rebuild switch --rollback`
|
||||
|
||||
### Secrets Management
|
||||
- Encrypted `secrets.yaml` **should be committed to git** (it's encrypted with age, safe to track)
|
||||
- SSH host key converts to age key automatically via `ssh-to-age`
|
||||
- Multi-recipient encryption allows both VPS and admin workstation to decrypt
|
||||
|
||||
### Common Pitfalls Avoided
|
||||
From 46+ ops-base deployments:
|
||||
|
||||
1. **Exit code 11 ≠ always segfault** - Often intentional exit_group(11) from config validation
|
||||
2. **SystemCallFilter restrictions** - Can block CPU affinity syscalls, needs allowances
|
||||
3. **LoadCredential patterns** - Use for Python scripts reading secrets from environment
|
||||
4. **ACME debugging** - Check `journalctl -u acme-*`, verify DNS, test staging first
|
||||
|
||||
## Build Statistics
|
||||
- **285 derivations built**
|
||||
- **378 paths fetched** (786.52 MiB download, 3.39 GiB unpacked)
|
||||
- **Boot time:** ~30 seconds
|
||||
- **Service startup:** All services up within 2 minutes
|
||||
|
||||
## Next Steps
|
||||
- [ ] Monitor mautrix-slack (currently segfaulting, needs investigation)
|
||||
- [ ] Establish regular deployment workflow (local build + remote deploy)
|
||||
- [ ] Configure remaining Matrix bridges (WhatsApp, Google Messages)
|
||||
- [ ] Set up monitoring/alerting
