Functions

func AddProxyConfigToCluster

func AddProxyConfigToCluster(ocConfig oc.OcConfig, proxy *network.ProxyConfig) error

func AddProxyToKubeletAndCriO

func AddProxyToKubeletAndCriO(sshRunner *ssh.SSHRunner, proxy *network.ProxyConfig) error

AddProxyToKubeletAndCriO adds the systemd drop-in proxy configuration file to the instance, both services (kubelet and crio) need to be restarted after this change. Since proxy operator is not able to make changes to in the kubelet/crio side, this is the job of machine config operator on the node and for crc this is not possible so we do need to put it here.

func AddPullSecret

func AddPullSecret(sshRunner *ssh.SSHRunner, ocConfig oc.OcConfig, pullSec string) error

func ApproveNodeCSR

func ApproveNodeCSR(ocConfig oc.OcConfig) error

ApproveNodeCSR approves the certificate for the node.

func CheckProxySettingsForOperator

func CheckProxySettingsForOperator(ocConfig oc.OcConfig, proxy *network.ProxyConfig, deployment, namespace string) (bool, error)

func DeleteOpenshiftApiServerPods

func DeleteOpenshiftApiServerPods(ocConfig oc.OcConfig) error

func GetRootPartitionUsage

func GetRootPartitionUsage(sshRunner *ssh.SSHRunner) (int64, int64, error)

Return size of disk, used space in bytes and the mountpoint

func RegenerateCertificates

func RegenerateCertificates(sshRunner *ssh.SSHRunner, ocConfig oc.OcConfig) error

func UpdateClusterID

func UpdateClusterID(ocConfig oc.OcConfig) error

func WaitForOpenshiftResource

func WaitForOpenshiftResource(ocConfig oc.OcConfig, resource string) error

func WaitForSsh

func WaitForSsh(sshRunner *ssh.SSHRunner) error

func WaitforRequestHeaderClientCaFile

func WaitforRequestHeaderClientCaFile(ocConfig oc.OcConfig) error
