K8s Daemonset in privilege mode

Functions

• Creation of the daemonset in priviledge mode
• Deletion of a daemonset in a specified namespace
• Check if a daemonset is ready within a specified time

Usage

1. Import the library

import k8sPriviledgedDs "github.com/redhat-cne/privileged-daemonset"

1. Set the K8s client to act on Daemonset object

k8sPriviledgedDs.SetDaemonSetClient(myK8sInterface) // myK8sInterface is of type kubernetes.Interface

1. Invoke the exported functions in a specified namespace with a specified imagename

To create

daemonSetRunningPods, err := k8sPriviledgedDs.CreateDaemonSet(myDaemonSetName, myNameSpace, daemonSetContainerName, imageWithVersion, timeOut)

To delete

err := k8sPriviledgedDs.DeleteDaemonSet(myDaemonSetName, myNameSpace)

To check if the daemonset is ready

err := k8sPriviledgedDs.WaitDaemonsetReady(myDaemonSetName, myNameSpace)

Functions

func ConfigurePrivilegedServiceAccount

func ConfigurePrivilegedServiceAccount(namespace string) error

func CreateDaemonSet

func CreateDaemonSet(daemonSetName, namespace, containerName, imageWithVersion string, labels map[string]string, env []v1core.EnvVar, timeout time.Duration, cpuReq, cpuLim, memReq, memLim string) (aPodList *v1core.PodList, err error)

This function is used to create a daemonset with the specified name, namespace, container name and image with the timeout to check if the deployment is ready and all daemonset pods are running fine

func DeleteDaemonSet

func DeleteDaemonSet(daemonSetName, namespace string) error

This method is used to delete a daemonset specified by the name at a specified namespace

func DeleteNamespaceIfPresent

func DeleteNamespaceIfPresent(namespace string) (err error)

func IsDaemonSetReady

func IsDaemonSetReady(daemonSetName, namespace, image string) bool

func SetDaemonSetClient

func SetDaemonSetClient(aK8sClient kubernetes.Interface)

func WaitDaemonsetReady

func WaitDaemonsetReady(namespace, name string, timeout time.Duration) error

This function is used to wait until daemonset is ready

Types
