feat: extraArgs allows same flag multiple times (#265) 
* feat: extraArgs allows same flag multiple times

Superseeds #244 (I messed up the rebase 🤦)

Relates to #232

This change allows ArgoCD chart to render multiple times the same flag with different values

Mainly, if not only, used to specify multiple Redis Sentinel addresses
5ec5aeb002/manifests/ha/base/overlays/argocd-application-controller-deployment.yaml (L16)
aeb48b0a69/util/cache/cache.go (L33)
```
--sentinel
```

using this syntax
```
controller:
  extraArgs:
  - --sentinel
  - argocd-redis-ha-announce-0
  - --sentinel
  - argocd-redis-ha-announce-1
  - --sentinel
  - argocd-redis-ha-announce-2
```

instead of

```
controller:
  extraArgs:
    sentinel=argocd-redis-ha-announce-0:
    sentinel=argocd-redis-ha-announce-1:
    sentinel=argocd-redis-ha-announce-2:
```

Basically same syntax as the flags documentation
```
docker run --rm argoproj/argocd:v1.4.2 argocd-server help
...

      --app-state-cache-expiration duration           Cache expiration for app state (default 1h0m0s)

      --as-group stringArray                          Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

Argo CD Chart

A Helm chart for ArgoCD, a declarative, GitOps continuous delivery tool for Kubernetes.

Source code can be found here

Additional Information

This is a community maintained chart. This chart installs argo-cd, a declarative, GitOps continuous delivery tool for Kubernetes.

The default installation is intended to be similar to the provided ArgoCD releases.

This chart currently installs the non-HA version of ArgoCD.

Upgrading

1.8.7 to 2.0.0

controller.extraArgs, repoServer.extraArgs and server.extraArgs are not arrays of strings intead of a map

What was

controller:
  extraArgs:
    insecure: ""

is now

controller:
  extraArgs:
  - --insecure

Prerequisites

  • Kubernetes 1.7+

Installing the Chart

To install the chart with the release name my-release:

$ helm repo add argo https://argoproj.github.io/argo-helm
$ helm install --name my-release argo/argo-cd

Helm v3 Compatability

Requires chart version 1.5.1 or newer.

Helm v3 has removed the install-crds hook so CRDs are now populated by files in the crds directory. Users of Helm v3 should set the installCRDs value to false to avoid warnings about nonexistant webhooks.
