Types

type ComposeConfig

type ComposeConfig struct {
	VMs       []Instance `yaml:"vms"`
	Namespace string     `yaml:"namespace"`
}

ComposeConfig defines a VMs orchestration template

type ConfigDriveMetaData

type ConfigDriveMetaData struct {
	AvailabilityZone string            `json:"availavility_zone"`
	Hostname         string            `json:"hostname"`
	LaunchIndex      string            `json:"launch_index"`
	Name             string            `json:"name"`
	Meta             map[string]string `json:"meta"`
	PublicKeys       map[string]string `json:"public_keys"`
	UUID             string            `json:"uuid"`
}

ConfigDriveMetaData stands for cloud images config drive

type Instance

type Instance struct {
	ID               string            `yaml:"id"`
	Name             string            `yaml:"name"`
	Namespace        string            `yaml:"namespace"`
	ParentImage      string            `yaml:"image"`
	Flavor           string            `yaml:"flavor"`
	Size             Size              `yaml:"size"`
	Workdir          string            `yaml:"workdir"`
	SSHPublicKeyFile string            `yaml:"sshkey"`
	UserData         string            `yaml:"user-data"`
	Cloud            bool              `yaml:"cloud"`
	Efi              bool              `yaml:"efi"`
	VNCPort          int64             `yaml:"vnc-port"`
	NetOpts          NetworkingOptions `yaml:"network"`
	Shares           []string          `yaml:"shares"`
	ContainerEnvVars []string          `yaml:"ContainerEnvVars"`
}

Instance contains all VM's attributes

func (*Instance) Check

func (ins *Instance) Check() (err error)

Check validates and fixes VMs values nolint: gocyclo, funlen, gocognit

type NetworkingOptions

type NetworkingOptions struct {
	IP    string   `yaml:"ip"`
	MAC   string   `yaml:"mac"`
	NetID string   `yaml:"net-id"`
	DNS   []string `yaml:"dns"`
}

NetworkingOptions specifies network details for new VM

type Size

type Size struct {
	CPUModel string `yaml:"cpu-model"`
	Sockets  int    `yaml:"sockets"`
	Cpus     int    `yaml:"cpus"`
	Cores    int    `yaml:"cores"`
	Threads  int    `yaml:"threads"`
	RAM      int    `yaml:"ram"`
	DISK     int    `yaml:"disk"`
}

Size specifies all custome VM size fields

func GetSizeFromFlavor

func GetSizeFromFlavor(flavor string) (size Size)

GetSizeFromFlavor gets default set of values from a given flavor

func NewSize
