Functions

func GPUNeedsFabricManager added in v0.12345678.1 

func GPUNeedsFabricManager(size string) bool

func GetAKSGPUImageSHA added in v0.12345678.1 

func GetAKSGPUImageSHA(size string) string

func GetCloudTargetEnv 

func GetCloudTargetEnv(location string) string
GetCloudTargetEnv determines and returns whether the region is a sovereign cloud which

have their own data compliance regulations (China/Germany/USGov) or standard. Azure public cloud.

func GetDataDir added in v0.12345678.1 

func GetDataDir(config *datamodel.NodeBootstrappingConfiguration) string

func GetGPUDriverVersion added in v0.12345678.1 

func GetGPUDriverVersion(size string) string

NV series GPUs target graphics workloads vs NC which targets compute. they typically use GRID, not CUDA drivers, and will fail to install CUDA drivers. NVv1 seems to run with CUDA, NVv5 requires GRID. NVv3 is untested on AKS, NVv4 is AMD so n/a, and NVv2 no longer seems to exist (?).

func GetKubeletConfigFileContent added in v0.0.1234 

func GetKubeletConfigFileContent(kc map[string]string, customKc *datamodel.CustomKubeletConfig) string

GetKubeletConfigFileContent converts kubelet flags we set to a file, and return the json content.

func GetKubernetesEndpoint added in v0.12345678.1 

func GetKubernetesEndpoint(cs *datamodel.ContainerService) string

func GetOrderedKubeletConfigFlagString added in v0.0.1234 

func GetOrderedKubeletConfigFlagString(config *datamodel.NodeBootstrappingConfiguration) string

GetOrderedKubeletConfigFlagString returns an ordered string of key/val pairs. copied from AKS-Engine and filter out flags that already translated to config file.

func GetTLSBootstrapTokenForKubeConfig added in v0.0.1234 

func GetTLSBootstrapTokenForKubeConfig(tlsBootstrapToken *string) string

GetTLSBootstrapTokenForKubeConfig returns the TLS bootstrap token for kubeconfig usage. It returns empty string if TLS bootstrap token is not enabled. ref: https://kubernetes.io/docs/reference/command-line-tools-reference/kubelet-tls-bootstrapping/#kubelet-configuration

func HasDataDir added in v0.12345678.1 

func HasDataDir(config *datamodel.NodeBootstrappingConfiguration) bool

func IsKubeletConfigFileEnabled added in v0.0.1234 

func IsKubeletConfigFileEnabled(cs *datamodel.ContainerService, profile *datamodel.AgentPoolProfile, kubeletConfigFileToggleEnabled bool) bool

IsKubeletConfigFileEnabled get if dynamic kubelet is supported in AKS and toggle is on.

func IsKubeletServingCertificateRotationEnabled added in v0.12345611.0 

func IsKubeletServingCertificateRotationEnabled(config *datamodel.NodeBootstrappingConfiguration) bool

func IsKubernetesVersionGe 

func IsKubernetesVersionGe(actualVersion, version string) bool

IsKubernetesVersionGe returns true if actualVersion is greater than or equal to version.

func IsSgxEnabledSKU 

func IsSgxEnabledSKU(vmSize string) bool

IsSgxEnabledSKU determines if an VM SKU has SGX driver support.

func IsTLSBootstrappingEnabledWithHardCodedToken added in v0.22222.0 

func IsTLSBootstrappingEnabledWithHardCodedToken(tlsBootstrapToken *string) bool

IsTLSBootstrappingEnabledWithHardCodedToken returns true if the specified TLS bootstrap token is non-nil, meaning we will use it to perform TLS bootstrapping.

func NewAgentBaker added in v0.0.1234 

func NewAgentBaker() (*agentBakerImpl, error)

func ValidateAndSetLinuxNodeBootstrappingConfiguration added in v0.12345678.1 

func ValidateAndSetLinuxNodeBootstrappingConfiguration(config *datamodel.NodeBootstrappingConfiguration)

ValidateAndSetLinuxNodeBootstrappingConfiguration is exported only for temporary usage in e2e testing of new config.
