Functions

func AgentImageDockerfilePath 

func AgentImageDockerfilePath() (string, error)

AgentImageDockerfilePath returns the stable managed legacy Arch Dockerfile path for the built-in agent runtime image.

func AgentImageHash 

func AgentImageHash() (string, error)

AgentImageHash returns a deterministic short hex fingerprint of the embedded agent image build context. The hash changes whenever any embedded file under images/agent is added, removed, renamed, or modified. It is suffixed onto the agent image tag so changes to embedded content force a fresh image instead of silently reusing a cached tag.

func BuiltinImageNames 

func BuiltinImageNames() []string

BuiltinImageNames returns supported managed image asset names.

func BuiltinTemplateNames 

func BuiltinTemplateNames() []string

BuiltinTemplateNames returns the built-in contain template names.

func ComposeBaseArgs 

func ComposeBaseArgs(name string) ([]string, string, error)

func ComposePath 

func ComposePath(name string) (string, error)

ComposePath returns the canonical compose.yaml path for a named contain workspace.

func ContainerDir 

func ContainerDir(name string) (string, error)

ContainerDir returns the configuration directory for a named contain workspace.

func ContainersRoot 

func ContainersRoot() (string, error)

ContainersRoot returns the global directory containing named contain workspaces.

func CreateWorkspace 

func CreateWorkspace(name string, opts CreateOptions) (string, error)

CreateWorkspace renders the selected template into the named global contain workspace directory. Existing targets are never overwritten.

func DockerPS 

func DockerPS(ctx context.Context, runner Runner, stderr io.Writer) ([]byte, error)

func Exec 

func Exec(ctx context.Context, runner Runner, name string, cmdArgs []string, stdin io.Reader, stdout, stderr io.Writer) error

func ImageDir 

func ImageDir(name string) (string, error)

ImageDir returns the managed directory for an image asset.

func ImagesRoot 

func ImagesRoot() (string, error)

ImagesRoot returns the directory containing managed contain image assets.

func IsBuiltinTemplate 

func IsBuiltinTemplate(name string) bool

IsBuiltinTemplate reports whether name is a built-in contain template.

func PrintList 

func PrintList(entries []ListEntry, w io.Writer) error

func ProjectName 

func ProjectName(name string) string

ProjectName returns the deterministic Docker Compose project name for a contain workspace.

func Rebuild 

func Rebuild(ctx context.Context, runner Runner, name string, stdout, stderr io.Writer) error

Rebuild rebuilds workspace images without cache, pulls newer base images where Compose can, and recreates containers while preserving volumes/networks.

func Remove 

func Remove(ctx context.Context, runner Runner, name string, stdout, stderr io.Writer) error

Remove permanently deletes a contain workspace: Compose resources are brought down with volumes removed, then the workspace definition directory is deleted.

func RenderTemplateContent 

func RenderTemplateContent(data []byte, values PlaceholderValues) ([]byte, error)

RenderTemplateContent applies simple placeholder substitution to data.

func ResolveTemplateValues 

func ResolveTemplateValues(desc *TemplateDescriptor, provided map[string]string, noInput bool, stdin io.Reader, stdout io.Writer) (map[string]string, error)

func SafeName 

func SafeName(name string) string

SafeName returns the deterministic name fragment used for Docker Compose project names and Docker resource names. It is tolerant so callers can use it in error paths, but valid workspace names should be checked with ValidateName.

func Shell 

func Shell(ctx context.Context, runner Runner, name string, stdin io.Reader, stdout, stderr io.Writer) error

func ShellWithOptions added in v0.0.193 

func ShellWithOptions(ctx context.Context, runner Runner, name string, opts ShellOptions, stdin io.Reader, stdout, stderr io.Writer) error

func Start 

func Start(ctx context.Context, runner Runner, name string, stdout, stderr io.Writer) error

func Stop 

func Stop(ctx context.Context, runner Runner, name string, stdout, stderr io.Writer) error

func ValidateName 

func ValidateName(name string) error

ValidateName validates a contain workspace name. Names are intentionally limited to simple path-safe characters because they are used as directory names below the global containers root.
