- Proxy local connections to Services running in the cluster
Connecting to Services
Not all Services running a Kubernetes cluster are exposed externally. However Services only exposed internally to a cluster with a clusterIp are accessible through an apiserver proxy.
Users may use Proxy to connect to Kubernetes Services in a cluster that are not externally exposed.
Note: Services running a type LoadBalancer or type NodePort may be exposed externally and accessed without the need for a Proxy.
Connecting to an internal Service
Connect to a internal Service using the Proxy command, and the Service Proxy url.
To visit the nginx service go to the Proxy URL at
kubectl proxy Starting to serve on 127.0.0.1:8001
To connect to a Service through a proxy the user must build the Proxy URL. The Proxy URL format is:
- The apiserver-address should be the URL printed by the Proxy command
- The Port is optional if you haven’t specified a name for your port
- The Protocol is optional if you are using
Builtin Cluster Services
A common usecase is to connect to Services running as part of the cluster itself. A user can print out these
Services and their Proxy Urls with
kubectl cluster-info Kubernetes master is running at https://184.108.40.206 GLBCDefaultBackend is running at https://220.127.116.11/api/v1/namespaces/kube-system/services/default-http-backend:http/proxy Heapster is running at https://18.104.22.168/api/v1/namespaces/kube-system/services/heapster/proxy KubeDNS is running at https://22.214.171.124/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy Metrics-server is running at https://126.96.36.199/api/v1/namespaces/kube-system/services/https:metrics-server:/proxy
