今天我們來介紹argo cd，argo cd 是一個在kubernetes上很受到歡迎的GitOps deploy工具，大家可以到官網有詳細的介紹。argo-cd

這邊我們使用helm來部署argo cd。argo cd installation

helm-argo.tf

resource "helm_release" "argo" {
  name       = "argo"
  repository = "https://argoproj.github.io/argo-helm"
  chart      = "argo-cd"
  version    = "5.5.4"
  timeout    = 300

  cleanup_on_fail = "true"
  create_namespace = "true"
  namespace = "argo"

  values = [
    "${file("data/argo-value.yaml")}"
  ]
}

data/argo-value.yaml

redis-ha:
  enabled: true

controller:
  replicas: 1

server:
  replicas: 2

repoServer:
  replicas: 2

applicationSet:
  replicas: 2

terraform apply 後就可以看到argo部署好了
