I'm working on kubernetes. Now I tried Digital Ocean's kubernetes which is very easy to install and access, but how can I install metric-server in it? how can I auto scale in kubernetes by DO? Please reply as soon as possible.
The Metrics Server can be installed to your cluster with Helm:
https://github.com/helm/charts/tree/master/stable/metrics-server
helm init
helm upgrade --install metrics-server --namespace=kube-system stable/metrics-serverwith RBAC enabled, see the more comprehensive instructions for installing Helm into your cluster:
https://github.com/helm/helm/blob/master/docs/rbac.md
If you wish to deploy without Helm, the manifests are available from the GitHub repository:
