# `argo1`

### A different opinionated opinion on how to bootstrap your ArgoCD

This repo is a basic skeleton for managing your apps with ArgoCD.

It uses helm to bootstrap and maintain the ArgoCD installation.  You may
then add additional applications in argo1/templates either as helm charts
or as directories which should live alongside `argo1`.

## Setup your own Argo1

1. Clone this repo as a template
2. If you will be using a private repo, configure a secret similar to secret.yaml
  1. You might also wish to use sealed secrets (via kubeseal).
3. Install CRDs

  *Preferred:*
  ```bash
  bash ./install-crds.sh
  ```

  This runs helm template but filters only the CRDs and installs them.  This is
  preferred to installing from tip of argocd since this helm template method
  will ensure the correct versions of CRDs are installed.

  *Alternative:*
  A suggested command to install via kubectl from [the ArgoCD docs][argo-crds]:

  ```bash
  kubectl apply -k https://github.com/argoproj/argo-cd/manifests/crds\?ref\=stable
  ```

  You will also need to find all the CRDs for any other applications in your
  templates.

3. update values.yaml
  * At the very least, you will need to update the bootstrap.source.repoURL to
    point to your clone -- this URL must match the prefix of the secret from
    step 2.
  * You may configure the argo-cd helm template via the argo-cd map in values.yaml.
    A basic example is available in the default values.yaml file which suppresses
    installing the CRDs (which are instead installed via install-crds.sh)
  
4. Install
   ```bash
   helm install --dependency-update argo1 .
   ```
5. all done!

## App of Apps pattern

This is already an app of apps.

Add additional applications to `templates/`.  These may reference Values or
they may be verbatim manifests (be careful of any `{{}}` in your manifests
though!)

Do not modify (or be careful with) `1-self.yaml` which is the application which
references this repo to enable self-management.
