func New added in v2.3.0 

func New(fileHandler file.Handler, name string) (*Config, error)

New creates a new config by: 1. Reading config file via provided fileHandler from file with name. 2. Read secrets from environment variables. 3. Validate config.

func (*Config) DeployCSIDriver added in v2.3.0 

func (c *Config) DeployCSIDriver() bool

DeployCSIDriver returns whether the CSI driver should be deployed for a given cloud provider.

func (*Config) EnforcesIDKeyDigest 

func (c *Config) EnforcesIDKeyDigest() bool

EnforcesIDKeyDigest checks whether ID Key Digest should be enforced for respective cloud provider.

func (*Config) GetProvider 

func (c *Config) GetProvider() cloudprovider.Provider

GetProvider returns the configured cloud provider.

func (*Config) HasProvider 

func (c *Config) HasProvider(provider cloudprovider.Provider) bool

HasProvider checks whether the config contains the provider.

func (*Config) IsAzureNonCVM 

func (c *Config) IsAzureNonCVM() bool

IsAzureNonCVM checks whether the chosen provider is azure and confidential VMs are disabled.

func (*Config) IsDebugCluster 

func (c *Config) IsDebugCluster() bool

func (*Config) RemoveProviderExcept 

func (c *Config) RemoveProviderExcept(provider cloudprovider.Provider)

RemoveProviderExcept removes all provider specific configurations, i.e., sets them to nil, except the one specified. If an unknown provider is passed, the same configuration is returned.

func (*Config) UpdateMeasurements 

func (c *Config) UpdateMeasurements(newMeasurements Measurements)

UpdateMeasurements overwrites measurements in config with the provided ones.

func (*Config) Validate 

func (c *Config) Validate() error
