const (
	LabelCodeflyOwner     = "codefly.owner"     // always "true"
	LabelCodeflySession   = "codefly.session"   // PID of the spawning CLI
	LabelCodeflyName      = "codefly.name"      // container's logical name
	LabelCodeflyEphemeral = "codefly.ephemeral" // "true" for SDK/test (--cli-server) containers
)

Container labels used by the startup sweep to identify codefly-owned containers and their spawning CLI. These are set on every container created via DockerEnvironment and consumed by ReapStaleContainers.

Functions

func ContainerName 

func ContainerName(name string) string

func DockerEngineRunning 

func DockerEngineRunning(ctx context.Context) bool

func EphemeralContainers 

func EphemeralContainers() bool

EphemeralContainers reports whether this process spawns ephemeral containers.

func Forward 

func Forward(ctx context.Context, reader io.Reader, writer io.Writer)

func GetImageID 

func GetImageID(im *resources.DockerImage) (string, error)

func GetImageIfNotPresent 

func GetImageIfNotPresent(ctx context.Context, c *client.Client, imag *resources.DockerImage, out io.Writer) error

func ImageExists 

func ImageExists(ctx context.Context, c *client.Client, imag *resources.DockerImage) (bool, error)

func PrintDownloadPercentage 

func PrintDownloadPercentage(reader io.ReadCloser, out io.Writer)

func ReapStaleContainers 

func ReapStaleContainers(ctx context.Context) error

func SetEphemeralContainers 

func SetEphemeralContainers(v bool)

SetEphemeralContainers marks dependency containers spawned by this process as ephemeral so the startup sweep reaps them even while running. The CLI calls this when it parses --cli-server.

Types

type DockerContainerInstance 

type DockerContainerInstance struct {
	ID string
}

type DockerEnvironment 

type DockerEnvironment struct {
	// contains filtered or unexported fields
}

func NewDockerEnvironment 

func NewDockerEnvironment(ctx context.Context, image *resources.DockerImage, dir, name string) (*DockerEnvironment, error)

NewDockerEnvironment creates a new docker environment.

If GetImageIfNotPresent fails, the docker client is closed before returning the error so the caller doesn't have to know about the half-constructed env (and isn't expected to call Shutdown on a nil return). Same defensive close in NewDockerHeadlessEnvironment.

func NewDockerHeadlessEnvironment 

func NewDockerHeadlessEnvironment(ctx context.Context, image *resources.DockerImage, name string) (*DockerEnvironment, error)

NewDockerHeadlessEnvironment creates a new docker runner

func (*DockerEnvironment) ContainerDeleted 

func (docker *DockerEnvironment) ContainerDeleted() (bool, error)

ContainerDeleted checks if the container with ID is gone

func (*DockerEnvironment) ContainerID 

func (docker *DockerEnvironment) ContainerID() (string, error)

func (*DockerEnvironment) GetContainer 

func (docker *DockerEnvironment) GetContainer(ctx context.Context) error

func (*DockerEnvironment) GetImageIfNotPresent 

func (docker *DockerEnvironment) GetImageIfNotPresent(ctx context.Context, imag *resources.DockerImage) error

func (*DockerEnvironment) GetLogs 

func (docker *DockerEnvironment) GetLogs(ctx context.Context) error

func (*DockerEnvironment) ImageExists 

func (docker *DockerEnvironment) ImageExists(ctx context.Context, imag *resources.DockerImage) (bool, error)

func (*DockerEnvironment) Init 

func (docker *DockerEnvironment) Init(ctx context.Context) error

func (*DockerEnvironment) IsContainerPresent 

func (docker *DockerEnvironment) IsContainerPresent(ctx context.Context) (bool, error)

func (*DockerEnvironment) NewProcess 

func (docker *DockerEnvironment) NewProcess(bin string, args ...string) (base.Proc, error)

func (*DockerEnvironment) PortMappings 

func (docker *DockerEnvironment) PortMappings() []*DockerPortMapping

func (*DockerEnvironment) Shutdown 

func (docker *DockerEnvironment) Shutdown(ctx context.Context) error

func (*DockerEnvironment) Stop 

func (docker *DockerEnvironment) Stop(ctx context.Context) error

func (*DockerEnvironment) TailLogs 

func (docker *DockerEnvironment) TailLogs(ctx context.Context, lines int) string

TailLogs returns the last `lines` lines of combined stdout+stderr for the container. Used by agent runtimes to enrich startup-failure errors with the actual container output (otherwise the user only sees a generic "not ready" timeout). Returns "" on any error so callers can safely append without conditional logic.

func (*DockerEnvironment) WithBinary 

func (docker *DockerEnvironment) WithBinary(bin string) error

func (*DockerEnvironment) WithCommand 

func (docker *DockerEnvironment) WithCommand(cmd ...string)

func (*DockerEnvironment) WithDir 

func (docker *DockerEnvironment) WithDir(dir string)

func (*DockerEnvironment) WithEnvironmentVariables 

func (docker *DockerEnvironment) WithEnvironmentVariables(ctx context.Context, envs ...*resources.EnvironmentVariable)

func (*DockerEnvironment) WithMount 

func (docker *DockerEnvironment) WithMount(sourceDir string, targetDir string)

func (*DockerEnvironment) WithOutput 

func (docker *DockerEnvironment) WithOutput(w io.Writer)

func (*DockerEnvironment) WithPause 

func (docker *DockerEnvironment) WithPause()

func (*DockerEnvironment) WithPort 

func (docker *DockerEnvironment) WithPort(ctx context.Context, port uint16)

func (*DockerEnvironment) WithPortMapping 

func (docker *DockerEnvironment) WithPortMapping(ctx context.Context, local uint16, container uint16)

func (*DockerEnvironment) WithWorkDir 

func (docker *DockerEnvironment) WithWorkDir(dir string)

type DockerPortMapping 

type DockerPortMapping struct {
	Host      uint16
	Container uint16
}

type DockerProc 

type DockerProc struct {
	ID string
	// contains filtered or unexported fields
}

func (*DockerProc) FindPid 

func (proc *DockerProc) FindPid(ctx context.Context) (int, error)

FindPid locates the PID of the matching child process inside the container by scanning /proc. /proc is guaranteed on every Linux container; `ps` is not (debian-slim images ship without procps, Alpine busybox has a different flag set). Output format is one line per PID: 

<pid>\t<cmdline-space-separated>

where cmdline is the full argv reconstructed from /proc/<pid>/cmdline (NUL-separated in the kernel — we convert NUL→space for splitting).

func (*DockerProc) IsRunning 

func (proc *DockerProc) IsRunning(ctx context.Context) (bool, error)

func (*DockerProc) Match 

func (proc *DockerProc) Match(cmd []string) bool

func (*DockerProc) Run 

func (proc *DockerProc) Run(ctx context.Context) error

func (*DockerProc) Start 

func (proc *DockerProc) Start(ctx context.Context) error

func (*DockerProc) StdinPipe 

func (proc *DockerProc) StdinPipe() (io.WriteCloser, error)

func (*DockerProc) StdoutPipe 

func (proc *DockerProc) StdoutPipe() (io.ReadCloser, error)

func (*DockerProc) Stop 

func (proc *DockerProc) Stop(ctx context.Context) error

func (*DockerProc) Wait 

func (proc *DockerProc) Wait(ctx context.Context) error

Wait blocks until the container process exits or ctx is cancelled. Polls IsRunning since Docker doesn't expose a clean blocking-wait here.

func (*DockerProc) WaitOn 

func (proc *DockerProc) WaitOn(bin string)

func (*DockerProc) WithDir 

func (proc *DockerProc) WithDir(dir string)

func (*DockerProc) WithEnvironmentVariables 

func (proc *DockerProc) WithEnvironmentVariables(ctx context.Context, envs ...*resources.EnvironmentVariable)

func (*DockerProc) WithEnvironmentVariablesAppend 

func (proc *DockerProc) WithEnvironmentVariablesAppend(ctx context.Context, added *resources.EnvironmentVariable, sep string)

func (*DockerProc) WithOutput 

func (proc *DockerProc) WithOutput(output io.Writer)

type DockerPullResponse 

type DockerPullResponse struct {
	ID             string         `json:"id"`
	Status         string         `json:"status"`
	ProgressDetail ProgressDetail `json:"progressDetail"`
}

type ProgressDetail 

type ProgressDetail struct {
	Current int `json:"current"`
	Total   int `json:"total"`
}
