Module for handling kubernetes calls.

configuration

The k8s API settings are provided either in a pillar, in the minion's config file, or in master's config file:

kubernetes.kubeconfig: '/path/to/kubeconfig'
kubernetes.kubeconfig-data: '<base64 encoded kubeconfig content'
kubernetes.context: 'context'

These settings can be overridden by adding context and `kubeconfig or kubeconfig_data parameters when calling a function.

The data format for kubernetes.kubeconfig-data value is the content of kubeconfig base64 encoded in one line.

Only kubeconfig or kubeconfig-data should be provided. In case both are provided kubeconfig entry is preferred.
