Replace upstream docker.io/library/redis:7-alpine with a nix-built container using Redis 8.2.3 from nixpkgs. Introduces the attached service pattern: parent field in service-versions.yaml, naming convention (<parent>-<component>), and version assertion in default.nix to prevent silent version drift on flake.lock updates.

# Review Services
|
|
|
|
How to periodically review BlumeOps services for version freshness and upgrade opportunities.
|
|
|
|
## Review by Staleness
|
|
|
|
Show services sorted by when they were last reviewed (most stale first):
|
|
|
|
```bash
|
|
mise run service-review
|
|
```
|
|
|
|
This reads the tracking file at `service-versions.yaml` (repo root) and sorts by the `last-reviewed` field. Services without a review date float to the top. The script shows a staleness table and then displays the most stale service with a review checklist.
|
|
|
|
To show more entries in the table:
|
|
|
|
```bash
|
|
mise run service-review --limit 30
|
|
```
|
|
|
|
To filter by service type:
|
|
|
|
```bash
|
|
mise run service-review --type argocd
|
|
mise run service-review --type ansible
|
|
mise run service-review --type hybrid
|
|
```
|
|
|
|
## Review Process by Service Type
|
|
|
|
### ArgoCD Services (`type: argocd`)
|
|
|
|
1. Check the upstream releases page for new versions
|
|
2. Compare to the image tag in `argocd/manifests/<service>/kustomization.yaml` (`images[].newTag`)
|
|
3. Review the upstream changelog for breaking changes
|
|
4. If the service uses a custom-built container, also check the base image for security updates and follow [[build-container-image]] to rebuild
|
|
5. If upgrading, update the manifest and follow [[deploy-k8s-service]]
|
|
|
|
### Ansible Services (`type: ansible`)
|
|
|
|
1. Check the upstream releases page for new versions
|
|
2. Review the role's vars/defaults for version pins in `ansible/roles/<service>/`
|
|
3. If upgrading, update the version and dry-run: `mise run provision-indri -- --tags <service> --check --diff`
|
|
4. Follow [[add-ansible-role]] patterns for role changes
|
|
|
|
### NixOS Services (`type: nixos`)
|
|
|
|
1. Check the upstream project for new releases
|
|
2. Review the Nix derivation or flake input for version pins
|
|
3. If upgrading, update and deploy via `mise run provision-ringtail`
|
|
|
|
## Attached Services
|
|
|
|
Some services have auxiliary dependencies that run as separate containers — caches, sidecars, init helpers. These are tracked as **attached services** with a naming convention and an optional `parent` field:
|
|
|
|
```yaml
|
|
- name: authentik-redis
|
|
type: argocd
|
|
parent: authentik
|
|
current-version: "8.2.3"
|
|
upstream-source: https://github.com/redis/redis/releases
|
|
notes: >-
|
|
Attached service: Redis cache/broker for Authentik.
|
|
```
|
|
|
|
**Conventions:**
|
|
|
|
- **Naming:** `<parent>-<component>` (e.g., `authentik-redis`, `grafana-sidecar`)
|
|
- **`parent` field:** points to the parent service entry. Currently informational — the review task doesn't use it yet, but it enables future grouping/dependency-aware reviews.
|
|
- **`notes` field:** always starts with "Attached service:" to make the relationship clear at a glance.
|
|
- **Version tracking:** attached services that use nixpkgs packages should include a version assertion in `default.nix` (`assert pkgs.<pkg>.version == version;`) so that `flake.lock` updates that change the package version break the build and force explicit acknowledgment.
|
|
|
|
Existing attached services: `grafana-sidecar`, `authentik-redis`.
|
|
|
|
## Version Tracking Convention
|
|
|
|
The `current-version` field in `service-versions.yaml` tracks the **upstream application version**, not the container image tag. For services with custom-built containers, the container image tag (e.g., `v1.0.0`) is decoupled from the contained app version (e.g., `v1.10.1`). This allows container rebuilds (base image updates, build fixes) without implying an upstream version change.
|
|
|
|
## Marking a Service as Reviewed
|
|
|
|
After reviewing, edit `service-versions.yaml` (repo root) and update the service entry:
|
|
|
|
```yaml
|
|
- name: prometheus
|
|
type: argocd
|
|
last-reviewed: 2026-02-16
|
|
current-version: "v3.9.1"
|
|
upstream-source: https://github.com/prometheus/prometheus/releases
|
|
```
|
|
|
|
Commit this change alongside any upgrades you make during the review.
