This repository contains deployment manifests for mindtastic's services

Usage

Creating and deploying a new application

In order to deploy a new application to Kuberentes you will need to do the following two things:

1. Create an Application manifest in ./applications; You can use the template below to create an application manifest for your application. Give it an appropriate name and store it in ./application.
2. create matching Kubernetes manifests for your application in a top level directory. Create a directory for your application manifests and save them. Make sure that your application manifest matches the directory name in the .spec.source.path attribute.

Once merged to the main branch, your new application should show up in ArgoCD shortly after.

Just press "Sync" to consolidate the manifests and cluster state and deploy your application.

Application Manifest Template

Use the following template to create a new Application Manifest:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: guestbook   # The name of your application
  namespace: argocd # Do not change this
  finalizers:
    - resources-finalizer.argocd.argoproj.io
spec:
  project: default
  source:
    repoURL: https://github.com/mindtastic/deployments
    targetRevision: HEAD
    path: guestbook # This points to the path where your application's manifests are stored
  destination:
    server: https://kubernetes.default.svc
    namespace: guestbook # Namespace for your application

Bootstraping

This repository is (mostly) fully automated. It follows ArgoCD's "App-of-Apps" pattern, albeit with small differences.

./applications.yaml deploys an ArgoCD application which creates all other applications stored in ./applications.

When bootstrapping a new Cluster, applications.yaml needs to be applied manually. After that it automatically adds all new applications added without any need to sync applications again.
