var ErrContainerTerminal = errors.New("container in terminal state")

ErrContainerTerminal indicates a container entered an unrecoverable state (e.g. "dead" or "removing") and cannot be restarted.

Functions

func LoadDockerConfig 

func LoadDockerConfig() (*configfile.ConfigFile, error)

Types

type Client 

type Client struct {
	dockerclient.CommonAPIClient
}

Client is a client for docker.

func NewClient 

func NewClient(ctx context.Context) (*Client, error)

NewClient creates a new docker client.

type ContainerRuntime added in v1.1.0 

type ContainerRuntime interface {
	Name() RuntimeName
	SupportsInternalBuildKit() bool
	SupportsSignalProxy() bool
	SupportsMountConsistency() bool
	NeedsUserNamespaceArgs() bool
	GPUAvailable(ctx context.Context, helper *DockerHelper) (bool, error)
}

ContainerRuntime describes the capabilities of a container runtime (Docker, Podman, nerdctl). Rather than checking IsPodman()/IsNerdctl() at every call site, callers query capability methods that express *why* the code branches.

func DetectRuntime added in v1.1.0 

func DetectRuntime(dockerCommand string) ContainerRuntime

DetectRuntime probes the binary at dockerCommand to determine which runtime it is. The result is cached per binary path.

func RuntimeFromName added in v1.1.0 

func RuntimeFromName(name string) (ContainerRuntime, error)

RuntimeFromName returns a ContainerRuntime for the given explicit name. Empty string defaults to Docker. Unknown non-empty names return an error to catch typos in provider configuration.

type DockerBuilder 

type DockerBuilder int

DockerBuilder represents the Docker builder types. 

const (
	DockerBuilderDefault DockerBuilder = iota
	DockerBuilderBuildX
	DockerBuilderBuildKit
)

Enum values for DockerBuilder.

func DockerBuilderFromString 

func DockerBuilderFromString(s string) (DockerBuilder, error)

func (DockerBuilder) String 

func (db DockerBuilder) String() string

type DockerHelper 

type DockerHelper struct {
	DockerCommand string
	// for a running container, we cannot pass down the container ID to the driver without introducing
	// changes in the driver interface (which we do not want to do). So, to get around this, we pass
	// it down to the driver during docker helper initialization.
	ContainerID string
	// allow command to have a custom environment
	Environment []string
	Builder     DockerBuilder
	Runtime     ContainerRuntime
}

func (*DockerHelper) DeleteVolume 

func (r *DockerHelper) DeleteVolume(ctx context.Context, volume string) error

func (*DockerHelper) FindContainer 

func (r *DockerHelper) FindContainer(ctx context.Context, labels []string) ([]string, error)

FindContainer will try to find a container based on the input labels. If no container is found, it will search for the labels manually inspecting containers.

func (*DockerHelper) FindContainerByID 

func (r *DockerHelper) FindContainerByID(
	ctx context.Context,
	containerIds []string,
) (*config.ContainerDetails, error)

func (*DockerHelper) FindContainerJSON 

func (r *DockerHelper) FindContainerJSON(ctx context.Context, labels []string) ([]string, error)

FindContainerJSON will manually search for containers with matching labels. This is useful in case the `--filter` doesn't work.

func (*DockerHelper) FindDevContainer 

func (r *DockerHelper) FindDevContainer(
	ctx context.Context,
	labels []string,
) (*config.ContainerDetails, error)

func (*DockerHelper) GPUSupportEnabled 

func (r *DockerHelper) GPUSupportEnabled() (bool, error)

func (*DockerHelper) GetContainerLogs 

func (r *DockerHelper) GetContainerLogs(
	ctx context.Context,
	id string,
	stdout io.Writer,
	stderr io.Writer,
) error

func (*DockerHelper) GetImageTag 

func (r *DockerHelper) GetImageTag(ctx context.Context, imageID string) (string, error)

func (*DockerHelper) GetRuntime added in v1.1.0 

func (r *DockerHelper) GetRuntime() ContainerRuntime

GetRuntime returns the container runtime for this helper. If no runtime was explicitly set, it auto-detects from the docker command.

func (*DockerHelper) Inspect 

func (r *DockerHelper) Inspect(
	ctx context.Context,
	ids []string,
	inspectType string,
	obj any,
) error

func (*DockerHelper) InspectContainers 

func (r *DockerHelper) InspectContainers(
	ctx context.Context,
	ids []string,
) ([]config.ContainerDetails, error)

func (*DockerHelper) InspectImage 

func (r *DockerHelper) InspectImage(
	ctx context.Context,
	imageName string,
	tryRemote bool,
) (*config.ImageDetails, error)

func (*DockerHelper) IsNerdctl 

func (r *DockerHelper) IsNerdctl() bool

func (*DockerHelper) IsPodman 

func (r *DockerHelper) IsPodman() bool

func (*DockerHelper) Pull 

func (r *DockerHelper) Pull(
	ctx context.Context,
	image string,
	stdin io.Reader,
	stdout io.Writer,
	stderr io.Writer,
) error

func (*DockerHelper) Remove 

func (r *DockerHelper) Remove(ctx context.Context, id string) error

func (*DockerHelper) Run 

func (r *DockerHelper) Run(
	ctx context.Context,
	args []string,
	stdin io.Reader,
	stdout io.Writer,
	stderr io.Writer,
) error

func (*DockerHelper) RunWithDir 

func (r *DockerHelper) RunWithDir(
	ctx context.Context,
	dir string,
	args []string,
	stdin io.Reader,
	stdout io.Writer,
	stderr io.Writer,
) error

func (*DockerHelper) StartContainer 

func (r *DockerHelper) StartContainer(ctx context.Context, containerId string) error

func (*DockerHelper) Stop 

func (r *DockerHelper) Stop(ctx context.Context, id string) error

func (*DockerHelper) WaitContainerRunning 

func (r *DockerHelper) WaitContainerRunning(ctx context.Context, containerID string) error

WaitContainerRunning polls docker inspect until the container reports status "running" or the context/timeout expires. It does not start the container — the caller is responsible for that.

type RuntimeName added in v1.1.0 

type RuntimeName string

RuntimeName identifies a container runtime. 

const (
	RuntimeDocker  RuntimeName = "docker"
	RuntimePodman  RuntimeName = "podman"
	RuntimeNerdctl RuntimeName = "nerdctl"
)
