# Install Argocd

## Online install
* 新增 argocd repo

$ helm repo add argo-cd https://argoproj.github.io/argo-helm

$ helm repo update

* 匯出 values.yaml

$ helm show values argo-cd/argo-cd > values.yaml

* 編輯 values.yaml，修改 Server service 為 nodeport

$ nano values.yaml
......
  ## Server service configuration
  service:
    # -- Server service annotations
    annotations: {}
    # -- Server service labels
    labels: {}
    # -- Server service type
    type: NodePort                # 將此行改為 NodePort  

* 開始安裝 argocd

$ kubectl create namespace argocd

$ helm install --values values.yaml argo-cd argo-cd/argo-cd --namespace argocd

* 環境檢查

$ kubectl -n argocd get all

* 使用 nodeport 方式登入


* argocd 解除安裝

$ helm -n argocd uninstall argo-cd

## Offline install

### 環境準備
* 新增 argocd repo，並做成壓縮檔
* 下載 argocd 所需 image，helm chart 7.3.7 所使用的 image 版本為 `argocd:v2.11.5`

$ helm repo add argo-cd https://argoproj.github.io/argo-helm

$ helm repo update

# helm chart 版本為 7.3.7
$ helm fetch argo-cd/argo-cd --version 7.3.7

$ ls -l argo-cd-7.3.7.tgz
-rw-r--r-- 1 root root 168621 Jul 17 10:07 argo-cd-7.3.7.tgz

# 下載 image
$ sudo podman pull quay.io/argoproj/argocd:v2.11.5 ghcr.io/dexidp/dex:v2.38.0 public.ecr.aws/docker/library/redis:7.2.4-alpine

$ sudo podman save -m quay.io/argoproj/argocd:v2.11.5 ghcr.io/dexidp/dex:v2.38.0 public.ecr.aws/docker/library/redis:7.2.4-alpine > argocd-v2.11.5.tar

### 離線環境安裝

* 將 image 解壓縮並上傳到內部 registry

$ sudo podman load < argocd-v2.11.5.tar

$ sudo podman tag quay.io/argoproj/argocd:v2.11.5 192.168.11.90/argoproj/argocd:v2.11.5

$ sudo podman tag public.ecr.aws/docker/library/redis:7.2.4-alpine 192.168.11.90/argoproj/redis:7.2.4-alpine

$ sudo podman tag ghcr.io/dexidp/dex:v2.38.0 192.168.11.90/argoproj/dex:v2.38.0

$ sudo podman push 192.168.11.90/argoproj/argocd:v2.11.5 

$ sudo podman push 192.168.11.90/argoproj/redis:7.2.4-alpine 

$ sudo podman push 192.168.11.90/argoproj/dex:v2.38.0

* 開始安裝 argocd，並將 server.service 換成 nodeport
* 需換成自己內部 registry 位置

$ kubectl create namespace argocd

$ helm template argo-cd ./argo-cd-7.3.7.tgz --output-dir . \
