# Cluster Bootstrapping Experiment Using Argo CD, App-of-Apps and Sync Waves
An experiment, running locally, to use the [App-of-Apps](https://argoproj.github.io/argo-cd/operator-manual/cluster-bootstrapping/) pattern of Argo CD to provision a cluster (the same cluster in this case) while declaring dependencies between the apps using Sync Waves.
## Requirements
- Docker
- `kubectl`
- [`k3d`](https://k3d.io)
- [`just`](https://github.com/casey/just)
- `bash`
- [`direnv`](https://direnv.net)
## Configuration
The configuration is done using [`.env`](./.env) and [`argo-cd.yaml`](argo-cd.yaml).
## Usage
Run the experiment:
```shell
just run
```
> The `run` recipe is idempotent.
Inspect the cluster.
Cleanup:
```shell
just clean
```
## Structure
```txt
.
├── app-of-apps.yaml <-- defines a cluster; one would have one of these per cluster
|── app-project.yaml <-- each cluster should reside in its own Argo CD `AppProject`
├── apps <-- this chart contains the apps of a cluster including dependencies
│ ├── Chart.yaml i.e. sync waves, hooks etc. (app-of-apps.yaml points to this chart)
│ ├── templates
│ │ ├── istio-operator.yaml
│ │ └── istio-profile.yaml
│ └── values.yaml
├── argo-cd.yaml <-- values file for the argo-cd demo deployment
├── charts <-- this directory simulates a chart musuem to be used
│ └── istio-profile by the Argo CD `Application` resources in the `apps` chart above
│ ├── Chart.yaml
│ ├── templates
│ │ ├── namespace.yaml
│ │ └── profile.yaml
│ └── values.yaml
├── justfile
├── k3d-default.yaml

```
## Known Issues
The health assessment of the `Application` resource was removed from Argo CD and has to be re-enabled using the `ConfigMap`.
See:
- https://github.com/argoproj/argo-cd/issues/5146
- https://github.com/argoproj/argo-cd/pull/6281
This experiment includes the patch.
