Static Pods

• Take me to Video Tutorial

In this section, we will take a look at Static Pods

How do you provide a pod definition file to the kubelet without a kube-apiserver?

• You can configure the kubelet to read the pod definition files from a directory on the server designated to store information about pods.

Configure Static Pod

• The designated directory can be any directory on the host and the location of that directory is passed in to the kubelet as an option while running the service.
  • The option is named as --pod-manifest-path.

  

Another way to configure static pod

• Instead of specifying the option directly in the kubelet.service file, you could provide a path to another config file using the config option, and define the directory path as staticPodPath in the file.

• To view the static pods

  $ docker ps
  

  

The kubelet can create both kinds of pods - the static pods and the ones from the api server at the same time.
