Flags are general command-line flags. Apps should add these flags to their own urfave/cli flags and call InitConfig() early in the application.

Functions

func InitConfig added in v0.2.0 

func InitConfig(ctx *cli.Context, exec kexec.Interface, defaults *Defaults) (string, error)

InitConfig reads the config file and common command-line options and constructs the global config object from them. It returns the config file path (if explicitly specified) or an error

func InitConfigWithPath added in v0.3.11 

func InitConfigWithPath(ctx *cli.Context, exec kexec.Interface, configFile string, defaults *Defaults) (string, error)

InitConfigWithPath reads the given config file (or if empty, reads the config file specified by command-line arguments, or empty, the default config file) and common command-line options and constructs the global config object from them. It returns the config file path (if explicitly specified) or an error

func ReadCNIConfig added in v0.3.11 

func ReadCNIConfig(bytes []byte) (*types.NetConf, error)

ReadCNIConfig unmarshals a CNI JSON config into an NetConf structure

func RestoreDefaultConfig added in v0.3.11 

func RestoreDefaultConfig()

RestoreDefaultConfig restores default config values. Used by testcases to provide a pristine environment between tests.

func UpdateOvnNodeAuth added in v0.3.0 

func UpdateOvnNodeAuth(masterIP string) error

UpdateOvnNodeAuth updates the host and URL in ClientAuth and ServerAuth for both OvnNorth and OvnSouth. It updates them with the new masterIP.

func WriteCNIConfig added in v0.3.11 

func WriteCNIConfig() error

WriteCNIConfig writes a CNI JSON config file to directory given by global config
