Exported flavor identifiers returned by Runtime.Flavor, so packages outside runtime (e.g. internal/container) can tailor user-facing messages to the runtime in use without depending on the unexported classifier.

Functions

func DetectInstalledFlavor added in v0.20.0 

func DetectInstalledFlavor() string

DetectInstalledFlavor reports which container runtime appears to be installed on this machine from filesystem/PATH evidence alone (state directories, the podman CLI), independent of the daemon lstk is connected to. This matters for hints when socket classification comes up empty — e.g. on Windows the daemon host is a named pipe, which classifySocketFlavor cannot attribute to any runtime, so Flavor() alone would hide runtime-specific fixes there.

Types

type BindMount added in v0.5.1 

type BindMount struct {
	HostPath      string
	ContainerPath string
	ReadOnly      bool
}

BindMount represents a host-to-container bind mount.

type ContainerBrief added in v0.20.0 

type ContainerBrief struct {
	Exists     bool
	Running    bool
	Created    bool   // state "created": created but never started
	AutoRemove bool   // created with --rm: removes itself once it exits
	Image      string // full image the container was created from
	Managed    bool   // carries the label Start stamps on every lstk container
}

ContainerBrief describes an existing container for pre-start checks, so callers can tell an lstk leftover (safe to self-heal) from a foreign container that happens to use the same name.

type ContainerConfig 

type ContainerConfig struct {
	Image         string
	Name          string
	EmulatorType  config.EmulatorType
	Port          string
	ContainerPort string // internal port the emulator listens on inside the container (e.g. "4566/tcp")
	BindHost      string // host IP to bind published ports to (e.g. "127.0.0.1" or "0.0.0.0"); defaults to loopback when empty
	HealthPath    string
	Env           []string // e.g., ["KEY=value", "FOO=bar"]
	Tag           string
	ProductName   string
	Binds         []BindMount
	ExtraPorts    []PortMapping
}
