From c6493f14ae78212b4d8bc498b0e43c98f95bcf42 Mon Sep 17 00:00:00 2001 From: Story Crater Bot <19826264+Riotpiaole@users.noreply.github.com> Date: Fri, 17 Jul 2026 23:42:55 -0700 Subject: [PATCH] feat(ci,iac): Consolidate Forgejo CI workflows and add Talos Terraform IaC Consolidate three separate Forgejo Actions (argocd-sync, security-scan, validate-k8s) into single cluster-ci workflow for cleaner CI/CD pipeline with proper job sequencing and reduced auth overhead. Add Terraform configuration for Talos cluster machine configs: - Provider setup for Talos - Centralized variables for CP and worker configs - Template-based config generation for controlplane.yaml and worker-*.yaml - Sensitive data separated in terraform.tfvars (gitignored) - Local state tracking for infrastructure --- .forgejo/workflows/argocd-sync.yaml | 66 ----- .forgejo/workflows/cluster-ci.yaml | 247 +++++++++++++++++++ .forgejo/workflows/security-scan.yaml | 125 ---------- .forgejo/workflows/validate-k8s.yaml | 118 --------- .gitignore | 1 + _FLUX_START_HERE.md | 324 ------------------------- docs/PHASE1-MIGRATION-GUIDE.md | 130 ---------- docs/TERRAFORM-STATE.md | 113 --------- terraform/.gitignore | 15 ++ terraform/main.tf | 126 ++++++++++ terraform/provider.tf | 12 + terraform/templates/controlplane.tftpl | 179 ++++++++++++++ terraform/templates/worker.tftpl | 83 +++++++ terraform/variables.tf | 168 +++++++++++++ 14 files changed, 831 insertions(+), 876 deletions(-) delete mode 100644 .forgejo/workflows/argocd-sync.yaml create mode 100644 .forgejo/workflows/cluster-ci.yaml delete mode 100644 .forgejo/workflows/security-scan.yaml delete mode 100644 .forgejo/workflows/validate-k8s.yaml delete mode 100644 _FLUX_START_HERE.md delete mode 100644 docs/PHASE1-MIGRATION-GUIDE.md delete mode 100644 docs/TERRAFORM-STATE.md create mode 100644 terraform/.gitignore create mode 100644 terraform/main.tf create mode 100644 terraform/provider.tf create mode 100644 terraform/templates/controlplane.tftpl create mode 100644 terraform/templates/worker.tftpl create mode 100644 terraform/variables.tf diff --git a/.forgejo/workflows/argocd-sync.yaml b/.forgejo/workflows/argocd-sync.yaml deleted file mode 100644 index 02896c9..0000000 --- a/.forgejo/workflows/argocd-sync.yaml +++ /dev/null @@ -1,66 +0,0 @@ -name: ArgoCD Sync on Main - -on: - push: - branches: - - main - paths: - - 'k8s/**' - -jobs: - argocd-sync: - runs-on: docker - steps: - - name: Checkout - run: | - REPO_URL="${{ gitea.server_url }}/${{ gitea.repository }}.git" - CLONE_URL="https://${{ secrets.CI_RUNNER }}:${{ secrets.CI_RUNNER_SECRET }}@${REPO_URL#https://}" - git clone --depth 1 "$CLONE_URL" . - cd ${GITHUB_WORKSPACE} - git fetch origin main - git checkout main - - - name: Install ArgoCD CLI - run: | - curl -sSL -o /usr/local/bin/argocd https://github.com/argoproj/argo-cd/releases/latest/download/argocd-linux-amd64 - chmod +x /usr/local/bin/argocd - - - name: Configure ArgoCD Access - env: - ARGOCD_SERVER: ${{ secrets.ARGOCD_SERVER }} - ARGOCD_AUTH_TOKEN: ${{ secrets.ARGOCD_AUTH_TOKEN }} - run: | - echo "Configured ArgoCD credentials" - - - name: Sync Root Application - env: - ARGOCD_SERVER: ${{ secrets.ARGOCD_SERVER }} - ARGOCD_AUTH_TOKEN: ${{ secrets.ARGOCD_AUTH_TOKEN }} - run: | - echo "=== Syncing homelab-root ===" - argocd app sync homelab-root --force - argocd app wait homelab-root --timeout 5m - - - name: Check Sync Status - env: - ARGOCD_SERVER: ${{ secrets.ARGOCD_SERVER }} - ARGOCD_AUTH_TOKEN: ${{ secrets.ARGOCD_AUTH_TOKEN }} - run: | - echo "=== ArgoCD Applications Status ===" - argocd app list -o table - - # Verify root app is synced - STATUS=$(argocd app get homelab-root -o jsonpath='{.status.syncStatus}') - if [ "$STATUS" != "Synced" ];
