1 簡介
我們之前使用了dapr的本地託管模式，但在生產中我們一般使用Kubernetes託管，本文介紹如何在GKE(GCP Kubernetes)安裝dapr。

2 安裝GKE
我們直接在網頁上安裝GKE，我們安裝的是Autopilot模式的GKE，如下：
點擊創建，等一段時間後就會創建成功了。
檢查 GKE狀態
需要安裝以下gcloud插件：
$ gcloud components install gke-gcloud-auth-plugin
獲取權限讓kubectl可以訪問：
$ gcloud container clusters get-credentials pkslow-autopilot --zone us-west1
查看node節點，說明正常啓動了：
$ kubectl get nodes
NAME STATUS ROLES AGE VERSION
gk3-pkslow-autopilot-default-pool-1bb48cfc-6jzc Ready <none> 64m v1.23.8-gke.1900
gk3-pkslow-autopilot-default-pool-33b02029-zz1d Ready <none> 64m v1.23.8-gke.1900
安裝dapr
創建namespace：
$ kubectl create ns pkslow-dapr
namespace/pkslow-dapr created
我們用helm工具來安裝，先添加倉庫：
$ helm repo add dapr https://dapr.github.io/helm-charts/
"dapr" has been added to your repositories
$ helm repo update
Hang tight while we grab the latest from your chart repositories...
...Successfully got an update from the "dapr" chart repository
...Successfully got an update from the "stable" chart repository
...Successfully got an update from the "k8ssandra" chart repository
...Successfully got an update from the "azure" chart repository
Update Complete. ⎈ Happy Helming!⎈
通過下面命令安裝dapr如下：
$ helm install dapr dapr/dapr --namespace pkslow-dapr
NAME: dapr
LAST DEPLOYED: Wed Nov 9 22:16:51 2022
NAMESPACE: pkslow-dapr
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
Thank you for installing Dapr: High-performance, lightweight serverless runtime for cloud and edge
Your release is named dapr.
To get started with Dapr, we recommend using our quickstarts:
https://github.com/dapr/quickstarts
For more information on running Dapr, visit:
https://dapr.io
過一段時間後，Pod啓動完成，然後查看狀態如下：
$ kubectl get pods -n pkslow-dapr
NAME READY STATUS RESTARTS AGE
dapr-dashboard-68d9d6c58-7nwqm 1/1 Running 0 2m58s
dapr-operator-5d44bd648d-6wlbf 1/1 Running 0 2m58s

dapr-sidecar-injector-84f85f5699-scz4c 1/1 Running 0 2m58s
查看dapr的Dashboard：
$ dapr dashboard -k -n pkslow-dapr
W1109 22:21:50.051562 52857 gcp.go:120] WARNING: the gcp auth plugin is deprecated in v1.22+, unavailable in v1.25+; use gcloud instead.

ℹ️ Dapr dashboard found in namespace: pkslow-dapr

總結
至此，我們在GKE成功地安裝了dapr。
