安装helm
- 下载与kubernetes版本对应的heml版本进行安装
- 安装
tar -zxvf helm-v3.8.0-linux-amd64.tar.gz
mv linux-amd64/helm /usr/local/bin/helm
安装ingress-nginx
# mkdir -p package/ingress-nginx

NOTES:
The ingress-nginx controller has been installed.
Get the application URL by running these commands:
export POD_NAME=$(kubectl --namespace ingress-nginx get pods -o jsonpath="{.items[0].metadata.name}" -l "app=ingress-nginx,component=controller,release=ingress-nginx")
kubectl --namespace ingress-nginx port-forward $POD_NAME 8080:80

# -- Improve connection draining when ingress controller pod is deleted using a lifecycle hook:
# With this new hook, we increased the default terminationGracePeriodSeconds from 30 seconds
# to 300, allowing the draining of connections up to five minutes.
# If the active connections end before that, the pod will terminate gracefully at that time.
# To effectively take advantage of this feature, the Configmap feature
# worker-shutdown-timeout new value is 240s instead of 10s.
