GitOps Platform

Implementation of GitOps architecture using ArgoCD with multi-dimensional configuration management across clouds, accounts, and environments.

ArgoCD + Applibrary + Configuration

1. Main ArgoCD Application

Read infrastructure schema from global.yaml and creates ApplicationSet per each cloud-account-environment combination (per cluster).

global.yaml

clouds:
  - name: aws
    accounts:
      - name: main
        environments:
          - name: common
          - name: stage
      - name: dedicated
        environments:
          - name: production

2. ApplicationSet cloud-account-environment

Search gitops repository for argo.yaml and creates applications based on settings.

application/ypur-app/argo.yaml

destination: all
namespace: api
autosync: true
syncOptions:
  - SkipDryRunOnMissingResource=true

3. Application

• uses Helm Applibrary from _chart/ as a dependency
• adds global configuration values files
• adds its own configuration values files

Key features

• ArgoCD managed everything
• ApplicationSet per cluster
• Monorepo for infra applications
• Dynamic application repo discovery
• Sophisticated DRY configuration hierarchy
• Developer Platform: ~0% ClickOps / ~100% GitOps

Tools

• crossplane
• keda
• reloader
