Erich Blume e152b1b071 Restrict flyio-proxy ACLs to dedicated tag:flyio-target endpoints

Replace broad tag:k8s and tag:homelab grants with a new tag:flyio-target
tag that services must explicitly opt into. Alloy now pushes logs/metrics
directly to Loki and Prometheus via Tailscale Ingress, bypassing Caddy.

Forgejo

Git forge and CI/CD platform. Primary source of truth for blumeops (mirrored to GitHub).

Quick Reference

Property	Value
URL	https://forge.ops.eblu.me
SSH	`ssh://forgejo@forge.ops.eblu.me:2222`
Local Ports	3001 (HTTP), 2200 (SSH)
Config	`ansible/roles/forgejo/templates/app.ini.j2`

Repositories

Repo	Description
`eblume/blumeops`	Infrastructure as code (primary)
`eblume/alloy`	Grafana Alloy fork (CGO build)
`eblume/tesla_auth`	Tesla OAuth helper
Helm chart mirrors	cloudnative-pg-charts, grafana-helm-charts

CI/CD (Forgejo Actions)

Runner: Kubernetes pod with Docker-in-Docker sidecar

Namespace: forgejo-runner
Labels: k8s
ArgoCD app: forgejo-runner

Workflows: .forgejo/workflows/

build-container.yaml - Container image builds on tag
build-blumeops.yaml - Documentation builds and releases

Secrets (Forgejo Config)

Server configuration secrets managed via 1Password → Ansible:

lfs-jwt-secret, internal-token, oauth2-jwt-secret - Forgejo server tokens
runner_reg - Runner registration token (also in k8s via external-secrets)

Forgejo Actions Secrets

Repository-level secrets for CI/CD workflows, synced from 1Password via Ansible.

Secret	1Password Field	Used By	Purpose
`ARGOCD_AUTH_TOKEN`	`argocd_token`	`build-blumeops.yaml`	Sync docs app after release

These secrets are injected as ${{ secrets.SECRET_NAME }} in workflow files.

IaC: The forgejo_actions_secrets Ansible role syncs these secrets from 1Password to Forgejo via the Forgejo API. Run with:

mise run provision-indri -- --tags forgejo_actions_secrets

API Token Setup (Manual, One-Time)

The Ansible role authenticates to the Forgejo API using a Personal Access Token (PAT). This PAT must be created manually:

Go to https://forge.ops.eblu.me/user/settings/applications
Create a new token with write:repository scope
Store it in 1Password → "Forgejo Secrets" item → api-token field

This is a bootstrapping requirement - the PAT enables IaC for all other secrets.

Future: Public Access

Forgejo can be exposed publicly at forge.eblu.me via flyio-proxy. Since Forgejo runs natively on indri (not in k8s), the pattern is:

Create a k8s ExternalName Service pointing to indri's Tailscale IP
Create a Tailscale Ingress with tailscale.com/tags: "tag:k8s,tag:flyio-target"
Add the nginx server block and DNS CNAME

Exposing a dynamic, authenticated service like Forgejo requires a full security review before going live:

Disable open user registration (require invites or admin approval)
Configure fail2ban on indri with a filter for Forgejo's log format
Ensure Forgejo logs the forwarded client IP (X-Real-IP) rather than the proxy's Tailscale IP
Audit repository visibility defaults and permissions
Rehearse the break-glass shutoff (mise run fly-shutoff)

See expose-service-publicly for the full howto and dynamic service checklist.

argocd - Uses Forgejo as git source
zot - Container registry for built images
