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)

Runners:

Runner Host Labels Purpose
k8s DinD pod indri (minikube) k8s Dockerfile builds via Dagger
ringtail-nix-builder ringtail (native) nix-container-builder Nix builds via nix-build + skopeo

Workflows: .forgejo/workflows/

  • build-container.yaml - Dockerfile builds on tag (runs on k8s)
  • build-container-nix.yaml - Nix builds on tag (runs on nix-container-builder)
  • build-blumeops.yaml - Documentation builds and releases

Both container workflows trigger on the same tag pattern (*-v[0-9]*). Each checks for its build file (Dockerfile or default.nix) and skips if not present. See build-container-image.

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:

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

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

Identity Provider

authentik is the BlumeOps OIDC identity provider and source of truth for user identity. Forgejo will eventually authenticate against Authentik as an OIDC client, with user provisioning managed in Authentik. This migration is deferred — the existing eblume account has extensive automations that need careful migration.

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:

  1. Create a k8s ExternalName Service pointing to indri's Tailscale IP
  2. Create a Tailscale Ingress with tailscale.com/tags: "tag:k8s,tag:flyio-target"
  3. 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
  • authentik - OIDC identity provider
  • zot - Container registry for built images
