async id() ServiceID[source]

A unique identifier for this Service.

Note

This is lazily evaluated, no operation is actually run.

Returns:

The ServiceID scalar type represents an identifier for an object of type Service.

Return type:

ServiceID

Raises:
async ports() list[Port][source]

Retrieves the list of ports provided by the service.

async start() Self[source]

Start the service and wait for its health checks to succeed.

Services bound to a Container do not need to be manually started.

Raises:
async stop(*, kill: bool | None = False) Self[source]

Stop the service.

Parameters:

kill – Immediately kill the service without waiting for a graceful exit

Raises:
async up(*, ports: list[PortForward] | None = None, random: bool | None = False) Void | None[source]

Creates a tunnel that forwards traffic from the caller’s network to this service.

Parameters:
  • ports – List of frontend/backend port mappings to forward. Frontend is the port accepting traffic on the host, backend is the service port.

  • random – Bind each tunnel port to a random port on the host.

Returns:

The absence of a value. A Null Void is used as a placeholder for resolvers that do not return anything.

Return type:

Void | None

Raises:
class dagger.ServiceID

Bases: Scalar

The ServiceID scalar type represents an identifier for an object of type Service.

class dagger.Socket(ctx: Context)

Bases: Type

A Unix or TCP/IP socket that can be mounted into a container.

async id() SocketID[source]

A unique identifier for this Socket.

Note

This is lazily evaluated, no operation is actually run.

Returns:

The SocketID scalar type represents an identifier for an object of type Socket.

Return type:

SocketID

Raises:
class dagger.SocketID

Bases: Scalar

The SocketID scalar type represents an identifier for an object of type Socket.

class dagger.Terminal(ctx: Context)

Bases: Type

An interactive terminal that clients can connect to.

async id() TerminalID[source]

A unique identifier for this Terminal.

Note

This is lazily evaluated, no operation is actually run.

Returns:

The TerminalID scalar type represents an identifier for an object of type Terminal.

Return type:

TerminalID

Raises:
async websocket_endpoint() str[source]

An http endpoint at which this terminal can be connected to over a websocket.

Returns:

The String scalar type represents textual data, represented as UTF-8 character sequences. The String type is most often used by GraphQL to represent free-form human-readable text.

Return type:

str

Raises:
class dagger.TerminalID

Bases: Scalar

The TerminalID scalar type represents an identifier for an object of type Terminal.

class dagger.TypeDef(ctx: Context)

Bases: Type

A definition of a parameter or return type in a Module.

as_input() InputTypeDef[source]

If kind is INPUT, the input-specific type definition. If kind is not INPUT, this will be null.

as_interface() InterfaceTypeDef[source]

If kind is INTERFACE, the interface-specific type definition. If kind is not INTERFACE, this will be null.

as_list() ListTypeDef[source]

If kind is LIST, the list-specific type definition. If kind is not LIST, this will be null.

as_object() ObjectTypeDef[source]

If kind is OBJECT, the object-specific type definition. If kind is not OBJECT, this will be null.

as_scalar() ScalarTypeDef[source]

If kind is SCALAR, the scalar-specific type definition. If kind is not SCALAR, this will be null.

async id() TypeDefID[source]

A unique identifier for this TypeDef.

Note

This is lazily evaluated, no operation is actually run.

Returns:

The TypeDefID scalar type represents an identifier for an object of type TypeDef.

Return type:

TypeDefID

Raises:
async kind() TypeDefKind[source]

The kind of type this is (e.g. primitive, list, object).

Returns:

Distinguishes the different kinds of TypeDefs.

Return type:

TypeDefKind

Raises:
async optional() bool[source]

Whether this type can be set to null. Defaults to false.

Returns:

The Boolean scalar type represents true or false.

Return type:

bool

Raises:
with_(cb: Callable[[TypeDef], TypeDef]) TypeDef[source]

Call the provided callable with current TypeDef.

This is useful for reusability and readability by not breaking the calling chain.

with_constructor(function: Function) Self[source]

Adds a function for constructing a new instance of an Object TypeDef, failing if the type is not an object.

with_field(name: str, type_def: Self, *, description: str | None = '') Self[source]

Adds a static field for an Object TypeDef, failing if the type is not an object.

Parameters:
  • name – The name of the field in the object

  • type_def – The type of the field

  • description – A doc string for the field, if any

with_function(function: Function) Self[source]

Adds a function for an Object or Interface TypeDef, failing if the type is not one of those kinds.

with_interface(name: str, *, description: str | None = '') Self[source]

Returns a TypeDef of kind Interface with the provided name.

with_kind(kind: TypeDefKind) Self[source]

Sets the kind of the type.

with_list_of(element_type: Self) Self[source]

Returns a TypeDef of kind List with the provided type for its elements.

with_object(name: str, *, description: str | None = '') Self[source]

Returns a TypeDef of kind Object with the provided name.

Note that an object’s fields and functions may be omitted if the intent is only to refer to an object. This is how functions are able to return their own object, or any other circular reference.

with_optional(optional: bool) Self[source]

Sets whether this type can be set to null.

with_scalar(name: str, *, description: str | None = '') Self[source]

Returns a TypeDef of kind Scalar with the provided name.

class dagger.TypeDefID

Bases: Scalar

The TypeDefID scalar type represents an identifier for an object of type TypeDef.

class dagger.TypeDefKind(value, names=None, *, module=None, qualname=None, type=None, start=1, boundary=None)

Bases: Enum

Distinguishes the different kinds of TypeDefs.

class dagger.Void

Bases: Scalar
