Functions

func ConvertBuild added in v5.2.0 

func ConvertBuild(build *parser.UnitFile, unitsInfoMap map[string]*UnitInfo, isUser bool) (*parser.UnitFile, error)

func ConvertContainer 

func ConvertContainer(container *parser.UnitFile, isUser bool, unitsInfoMap map[string]*UnitInfo) (*parser.UnitFile, error)

Convert a quadlet container file (unit file with a Container group) to a systemd service file (unit file with Service group) based on the options in the Container group. The original Container group is kept around as X-Container.

func ConvertImage 

func ConvertImage(image *parser.UnitFile, unitsInfoMap map[string]*UnitInfo, isUser bool) (*parser.UnitFile, error)

func ConvertKube 

func ConvertKube(kube *parser.UnitFile, unitsInfoMap map[string]*UnitInfo, isUser bool) (*parser.UnitFile, error)

func ConvertNetwork 

func ConvertNetwork(network *parser.UnitFile, name string, unitsInfoMap map[string]*UnitInfo, isUser bool) (*parser.UnitFile, error)

Convert a quadlet network file (unit file with a Network group) to a systemd service file (unit file with Service group) based on the options in the Network group. The original Network group is kept around as X-Network. Also returns the canonical network name, either auto-generated or user-defined via the NetworkName key-value.

func ConvertPod 

func ConvertPod(podUnit *parser.UnitFile, name string, unitsInfoMap map[string]*UnitInfo, isUser bool) (*parser.UnitFile, error)

func ConvertVolume 

func ConvertVolume(volume *parser.UnitFile, name string, unitsInfoMap map[string]*UnitInfo, isUser bool) (*parser.UnitFile, error)

Convert a quadlet volume file (unit file with a Volume group) to a systemd service file (unit file with Service group) based on the options in the Volume group. The original Volume group is kept around as X-Volume. Also returns the canonical volume name, either auto-generated or user-defined via the VolumeName key-value.

func GetBuildServiceName added in v5.3.0 

func GetBuildServiceName(podUnit *parser.UnitFile) string

func GetBuiltImageName added in v5.2.0 

func GetBuiltImageName(buildUnit *parser.UnitFile) string

func GetContainerResourceName added in v5.4.0 

func GetContainerResourceName(container *parser.UnitFile) string

Get the resolved container name that contains no '%'. Returns an empty string if not resolvable.

func GetContainerServiceName added in v5.3.0 

func GetContainerServiceName(podUnit *parser.UnitFile) string

func GetImageServiceName added in v5.3.0 

func GetImageServiceName(podUnit *parser.UnitFile) string

func GetKubeServiceName added in v5.3.0 

func GetKubeServiceName(podUnit *parser.UnitFile) string

func GetNetworkServiceName added in v5.3.0 

func GetNetworkServiceName(podUnit *parser.UnitFile) string

func GetPodServiceName 

func GetPodServiceName(podUnit *parser.UnitFile) string

func GetVolumeServiceName added in v5.3.0 

func GetVolumeServiceName(podUnit *parser.UnitFile) string

Types

type PodmanCmdline 

type PodmanCmdline struct {
	Args []string
}

This is a helper for constructing podman commandlines

func NewPodmanCmdline 

func NewPodmanCmdline(args ...string) *PodmanCmdline

type UnitInfo added in v5.3.0 

type UnitInfo struct {
	// The name of the generated systemd service unit
	ServiceName string
	// The name of the podman resource created by the service
	ResourceName string

	// For .pod units
	// List of containers to start with the pod
	ContainersToStart []string
}

func (*UnitInfo) ServiceFileName added in v5.3.0 

func (u *UnitInfo) ServiceFileName() string
