Pulumi Python SDK

The Pulumi Python SDK (pulumi) is the core package used when writing Pulumi programs in Python. It contains everything that you’ll need in order to interact with Pulumi resource providers and express infrastructure using Python code. Pulumi resource providers all depend on this library and express their resources in terms of the types defined in this module.

Note: The Pulumi Python SDK requires Python version 3.6 or greater. Please see the Python getting started documentation for details on how to get started with Python.

The Pulumi Python Resource Model

Like most languages usable with Pulumi, Pulumi represents cloud resources as classes and Python programs can instantiate those classes. All classes that can be instantiated to produce actual resources derive from the pulumi.Resource class.

A class that derives from pulumi.Resource will, when instantiated, communicate with the Pulumi Engine and record that a piece of infrastructure that the instantiated class represents should be provisioned. All resources whose provisioning is implemented in a resource provider derive from the pulumi.CustomResource class.

It is also possible to write your own resources, written in Python, that are themselves composed of custom resources. Resources written in Python are called “component resources” and they are written by deriving from the pulumi.ComponentResource class.

Finally, Pulumi allows for resource providers to directly project themselves into Python, so that provider instances can be instantiated and used to create other resources. These “provider resources” derive from the pulumi.ProviderResource class.

class pulumi.Resource(t: str, name: str, custom: bool, props: Optional[Inputs] = None, opts: Optional[pulumi.resource.ResourceOptions] = None, remote: bool = False, dependency: bool = False)

Resource represents a class whose CRUD operations are implemented by a provider plugin.

Parameters

t (str) – The type of this resource.
name (str) – The name of this resource.
custom (bool) – True if this resource is a custom resource.
props (Optional[Inputs]) – An optional list of input properties to use as inputs for the resource. If props is an input type (decorated with @input_type), dict keys will be translated using the type’s and resource’s type/name metadata rather than using the translate_input_property and translate_output_property methods.
opts (Optional[ResourceOptions]) – Optional set of pulumi.ResourceOptions to use for this resource.
remote (bool) – True if this is a remote component resource.
dependency (bool) – True if this is a synthetic resource used internally for dependency tracking.

property urn: The stable, logical URN used to distinctly address a resource, both before and after deployments.

translate_output_property(prop: str) → str

Provides subclasses of Resource an opportunity to translate names of output properties into a format of their choosing before writing those properties to the resource object.

If the props passed to __init__ is an input type (decorated with @input_type), the type/name metadata of the resource will be used to translate names instead of calling this method.

Parameters: prop (str) – A property name.
Returns: A potentially transformed property name.
Return type: str

translate_input_property(prop: str) → str

Provides subclasses of Resource an opportunity to translate names of input properties into a format of their choosing before sending those properties to the Pulumi engine.

If the props passed to __init__ is an input type (decorated with @input_type), the type/name metadata of props will be used to translate names instead of calling this method.

Parameters: prop (str) – A property name.
Returns: A potentially transformed property name.
Return type: str

get_provider(module_member: str) → Optional[pulumi.resource.ProviderResource]

Fetches the provider for the given module member, if this resource has been provided a specific provider for the given module member.

Returns None if no provider was provided.

Parameters: module_member (str) – The requested module member.
Returns: The ProviderResource associated with the given module member, or None if one does not exist.
Return type: Optional[ProviderResource]

class pulumi.CustomResource(t: str, name: str, props: Optional[dict] = None, opts: Optional[pulumi.resource.ResourceOptions] = None, dependency: bool = False)

CustomResource is a resource whose create, read, update, and delete (CRUD) operations are managed by performing external operations on some physical entity. The engine understands how to diff and perform partial updates of them, and these CRUD operations are implemented in a dynamically loaded plugin for the defining package.

Parameters

t (str) – The type of this resource.
name (str) – The name of this resource.
props (Optional[dict]) – An optional list of input properties to use as inputs for the resource.
opts (Optional[ResourceOptions]) – Optional set of pulumi.ResourceOptions to use for this resource.
dependency (bool) – True if this is a synthetic resource used internally for dependency tracking.

property id: id is the provider-assigned unique ID for this managed resource. It is set during deployments and may be missing (undefined) during planning phases.

class pulumi.ComponentResource(t: str, name: str, props: Optional[dict] = None, opts: Optional[pulumi.resource.ResourceOptions] = None, remote: bool = False)

ComponentResource is a resource that aggregates one or more other child resources into a higher level abstraction. The component itself is a resource, but does not require custom CRUD operations for provisioning.

Parameters

t (str) – The type of this resource.
name (str) – The name of this resource.
props (Optional[dict]) – An optional list of input properties to use as inputs for the resource.
opts (Optional[ResourceOptions]) – Optional set of pulumi.ResourceOptions to use for this resource.
remote (bool) – True if this is a remote component resource.

register_outputs(outputs)

Register synthetic outputs that a component has initialized, usually by allocating other child sub-resources and propagating their resulting property values.

Parameters: output (dict) – A dictionary of outputs to associate with this resource.

class pulumi.ProviderResource(pkg: str, name: str, props: Optional[dict] = None, opts: Optional[pulumi.resource.ResourceOptions] = None, dependency: bool = False)

ProviderResource is a resource that implements CRUD operations for other custom resources. These resources are managed similarly to other resources, including the usual diffing and update semantics.

Parameters

pkg (str) – The package type of this provider resource.
name (str) – The name of this resource.
props (Optional[dict]) – An optional list of input properties to use as inputs for the resource.
opts (Optional[ResourceOptions]) – Optional set of pulumi.ResourceOptions to use for this resource.
dependency (bool) – True if this is a synthetic resource used internally for dependency tracking.

aliases: Optional[Sequence[Input[Union[str, Alias]]]]: An optional list of aliases to treat this resource as matching.

additional_secret_outputs: Optional[List[str]]: The names of outputs for this resource that should be treated as secrets.

custom_timeouts: Optional[CustomTimeouts]: An optional customTimeouts config block.

id: Optional[Input[str]]: An optional existing ID to load, rather than create.

import_: Optional[str]: When provided with a resource ID, import indicates that this resource’s provider should import its state from the cloud resource with the given ID. The inputs to the resource’s constructor must align with the resource’s current state. Once a resource has been imported, the import property must be removed from the resource’s options.

transformations: Optional[List[Callable[[pulumi.resource.ResourceTransformationArgs], Optional[pulumi.resource.ResourceTransformationResult]]]]: Optional list of transformations to apply to this resource during construction. The transformations are applied in order, and are applied prior to transformation applied to parents walking from the resource up to the stack.

urn: Optional[str]: The URN of a previously-registered resource of this type to read from the engine.

replace_on_changes: Optional[List[str]]: Changes to any of these property paths will force a replacement. If this list includes "*", changes to any properties will force a replacement. Initialization errors from previous deployments will require replacement instead of update only if "*" is passed.

depends_on: Optional[Input[Union[Sequence[Input[Resource]], Resource]]]: If provided, declares that the currently-constructing resource depends on the given resources.

static merge(opts1: Optional[pulumi.resource.ResourceOptions], opts2: Optional[pulumi.resource.ResourceOptions]) → pulumi.resource.ResourceOptions

merge produces a new ResourceOptions object with the respective attributes of the opts1 instance in it with the attributes of opts2 merged over them.

Both the opts1 instance and the opts2 instance will be unchanged. Both of opts1 and opts2 can be None, in which case its attributes are ignored.

Conceptually attributes merging follows these basic rules:

If the attributes is a collection, the final value will be a collection containing the values from each options object. Both original collections in each options object will be unchanged.
Simple scalar values from opts2 (i.e. strings, numbers, bools) will replace the values from opts1.
For the purposes of merging depends_on, provider and providers are always treated as collections, even if only a single value was provided.
Attributes with value ‘None’ will not be copied over.

This method can be called either as static-method like ResourceOptions.merge(opts1, opts2) or as an instance-method like opts1.merge(opts2). The former is useful for cases where opts1 may be None so the caller does not need to check for this case.

class pulumi.InvokeOptions(parent: Optional[Resource] = None, provider: Optional[ProviderResource] = None, version: Optional[str] = '', plugin_download_url: Optional[str] = None)

InvokeOptions is a bag of options that control the behavior of a call to runtime.invoke.

version (Optional[str]) – An optional version. If provided, the provider plugin with exactly this version will be used to service the invocation.
plugin_download_url (Optional[str]) – An optional URL. If provided, the provider plugin with this download URL will be used to service the invocation. This will override the URL sourced from the host package, and should be rarely used.

parent: Optional[Resource]: An optional parent to use for default options for this invoke (e.g. the default provider to use).

exception pulumi.RunError: Can be used for terminating a program abruptly, but resulting in a clean exit rather than the usual verbose unhandled error logic which emits the source program text and complete stack trace.

Configuration and Metadata

Pulumi programs can receive configuration that is specified by the command-line using pulumi config. This configuration information can be retrieved at runtime using the pulumi.Config class:

import pulumi
# After running `pulumi config set myconfig 42`
conf = pulumi.Config()
print(conf.get_int("myconfig")) # prints 42

Pulumi programs also have the ability to query the current project and stack, as well as whether or not the current run of the program is a preview or not.

class pulumi.Config(name: Optional[str] = None)

Config is a bag of related configuration state. Each bag contains any number of configuration variables, indexed by simple keys, and each has a name that uniquely identifies it; two bags with different names do not share values for variables that otherwise share the same key. For example, a bag whose name is pulumi:foo, with keys a, b, and c, is entirely separate from a bag whose name is pulumi:bar with the same simple key names. Each key has a fully qualified names, such as pulumi:foo:a, …, and pulumi:bar:a, respectively.

Outputs and Inputs

Like other languages in the Pulumi ecosystem, all Resources in Python have two kinds of properties: inputs and outputs. Inputs are specified as arguments to resource constructors, to be used as inputs to the resource itself. Outputs are returned as properties on the instantiated resource object. Outputs are similar to futures in that they are resolved asynchronously, but they also contain information about the dependency graph of resources within your program.

Pulumi does not offer direct access to the values contained within Outputs. Instead, you must use the apply function on the Output class in order to observe the value of an output. See the documentation for more details on this part of the Pulumi programming model.

class pulumi.Output(resources: Union[Awaitable[Set[Resource]], Set[Resource]], future: Awaitable[T_co], is_known: Awaitable[bool], is_secret: Optional[Awaitable[bool]] = None)

Output helps encode the relationship between Resources in a Pulumi application. Specifically an Output holds onto a piece of Data and the Resource it was generated from. An Output value can then be provided when constructing new Resources, allowing that new Resource to know both the value as well as the Resource the value came from. This allows for a precise ‘Resource dependency graph’ to be created, which properly tracks the relationship between resources.

__getitem__(key: Any) → pulumi.output.Output[Any]

Syntax sugar for looking up attributes dynamically off of outputs.

Parameters: key (Any) – Key for the attribute dictionary.
Returns: An Output of this Output’s underlying value, keyed with the given key as if it were a dictionary.
Return type: Output[Any]

__getattr__(item: str) → pulumi.output.Output[Any]

Syntax sugar for retrieving attributes off of outputs.

Parameters: item (str) – An attribute name.
Returns: An Output of this Output’s underlying value’s property with the given name.
Return type: Output[Any]

apply(func: Callable[[T_co], Union[U, Awaitable[U], pulumi.output.Output[T]]], run_with_unknowns: Optional[bool] = None) → pulumi.output.Output[U]

Transforms the data of the output with the provided func. The result remains an Output so that dependent resources can be properly tracked.

‘func’ is not allowed to make resources.

‘func’ can return other Outputs. This can be handy if you have a Output and you want to get a transitive dependency of it.

This function will be called during execution of a ‘pulumi up’ request. It may not run during ‘pulumi preview’ (as the values of resources are of course may not be known then).

Parameters: func (Callable[[T_co],Input[U]]) – A function that will, given this Output’s value, transform the value to an Input of some kind, where an Input is either a prompt value, a Future, or another Output of the given type.
Returns: A transformed Output obtained from running the transformation function on this Output’s value.
Return type: Output[U]

static from_input(val: Union[T_co, Awaitable[T_co], pulumi.output.Output[T]]) → pulumi.output.Output[T_co]

Takes an Input value and produces an Output value from it, deeply unwrapping nested Input values through nested lists, dicts, and input classes. Nested objects of other types (including Resources) are not deeply unwrapped.

Parameters: val (Input[T_co]) – An Input to be converted to an Output.
Returns: A deeply-unwrapped Output that is guaranteed to not contain any Input values.
Return type: Output[T_co]

static unsecret(val: pulumi.output.Output[T]) → pulumi.output.Output[T]

Takes an existing Output, deeply unwraps the nested values and returns a new Output without any secrets included

Parameters: val (Output[T]) – An Output to be converted to a non-Secret Output.
Returns: A deeply-unwrapped Output that is guaranteed to not contain any secret values.
Return type: Output[T]

static secret(val: Union[T, Awaitable[T], pulumi.output.Output[T]]) → pulumi.output.Output[T]

Takes an Input value and produces an Output value from it, deeply unwrapping nested Input values as necessary given the type. It also marks the returned Output as a secret, so its contents will be persisted in an encrypted form in state files.

Parameters: val (Input[T]) – An Input to be converted to an Secret Output.
Returns: A deeply-unwrapped Output that is guaranteed to not contain any Input values and is marked as a Secret.
Return type: Output[T]

static all(*args: Union[T, Awaitable[T], Output[T]]) → Output[List[T]]

static all(**kwargs: Union[T, Awaitable[T], Output[T]]) → Output[Dict[str, T]]

Produces an Output of a list (if args i.e a list of inputs are supplied) or dict (if kwargs i.e. keyworded arguments are supplied).

This function can be used to combine multiple, separate Inputs into a single Output which can then be used as the target of apply. Resource dependencies are preserved in the returned Output.

Examples:

Output.all(foo, bar) -> Output[[foo, bar]]
Output.all(foo=foo, bar=bar) -> Output[{"foo": foo, "bar": bar}]

Parameters

args (Input[T]) – A list of Inputs to convert.
kwargs (Input[T]) – A list of named Inputs to convert.

Returns

An output of list or dict, converted from unnamed or named Inputs respectively.

static concat(*args: Union[str, Awaitable[str], pulumi.output.Output[T]]) → pulumi.output.Output[str]

Concatenates a collection of Input[str] into a single Output[str].

This function takes a sequence of Input[str], stringifies each, and concatenates all values into one final string. This can be used like so:

url = Output.concat("http://", server.hostname, ":", loadBalancer.port)

Parameters: args (Input[str]) – A list of string Inputs to concatenate.
Returns: A concatenated output string.
Return type: Output[str]

Logging

The Pulumi SDK contains a few helper functions for logging to the console. Messages logged using these functions are sent directly to the Pulumi Engine and rendered with the rest of the CLI output.

pulumi.debug(msg: str, resource: Optional[Resource] = None, stream_id: Optional[int] = None, ephemeral: Optional[bool] = None) → None

Logs a message to the Pulumi CLI’s debug channel, associating it with a resource and stream_id if provided.

Parameters

msg (str) – The message to send to the Pulumi CLI.
resource (Optional[Resource]) – If provided, associate this message with the given resource in the Pulumi CLI.
stream_id (Optional[int]) – If provided, associate this message with a stream of other messages.

pulumi.info(msg: str, resource: Optional[Resource] = None, stream_id: Optional[int] = None, ephemeral: Optional[bool] = None) → None

Logs a message to the Pulumi CLI’s info channel, associating it with a resource and stream_id if provided.

Parameters

msg (str) – The message to send to the Pulumi CLI.
resource (Optional[Resource]) – If provided, associate this message with the given resource in the Pulumi CLI.
stream_id (Optional[int]) – If provided, associate this message with a stream of other messages.

pulumi.warn(msg: str, resource: Optional[Resource] = None, stream_id: Optional[int] = None, ephemeral: Optional[bool] = None) → None

Logs a message to the Pulumi CLI’s warning channel, associating it with a resource and stream_id if provided.

Parameters

msg (str) – The message to send to the Pulumi CLI.
resource (Optional[Resource]) – If provided, associate this message with the given resource in the Pulumi CLI.
stream_id (Optional[int]) – If provided, associate this message with a stream of other messages.

pulumi.error(msg: str, resource: Optional[Resource] = None, stream_id: Optional[int] = None, ephemeral: Optional[bool] = None)

Logs a message to the Pulumi CLI’s error channel, associating it with a resource and stream_id if provided.

Consider raising an exception after calling error to stop the Pulumi program.

Parameters

msg (str) – The message to send to the Pulumi CLI.
resource (Optional[Resource]) – If provided, associate this message with the given resource in the Pulumi CLI.
stream_id (Optional[int]) – If provided, associate this message with a stream of other messages.

Stack Exports

Python programs can export values. Exported values are attached to the program’s Stack resource and accessed using the pulumi stack output CLI command:

import pulumi
pulumi.export("the-answer", 42)
# pulumi stack export:
# Current stack outputs (1):
# OUTPUT      VALUE
# the-answer  42

pulumi.export(name: str, value: Any)

Exports a named stack output.

Parameters

name (str) – The name to assign to this output.
value (Any) – The value of this output.

Automation API

The automation module contains the Pulumi Automation API, the programmatic interface for driving Pulumi programs without the CLI. Generally this can be thought of as encapsulating the functionality of the CLI (pulumi up, pulumi preview, pulumi destroy, pulumi stack init, etc.) but with more flexibility. This still requires a CLI binary to be installed and available on your $PATH.

In addition to fine-grained building blocks, Automation API provides two out of the box ways to work with Stacks:

Programs locally available on-disk and addressed via a filepath (local source):

stack = create_stack("myOrg/myProj/myStack", work_dir=os.path.join("..", "path", "to", "project"))

Programs defined as a function alongside your Automation API code (inline source):

def pulumi_program():
    bucket = s3.Bucket("bucket")
    pulumi.export("bucket_name", bucket.Bucket)
stack = create_stack("myOrg/myProj/myStack", program=pulumi_program)

Each of these creates a stack with access to the full range of Pulumi lifecycle methods (up/preview/refresh/destroy), as well as methods for managing config, stack, and project settings:

stack.set_config("key", ConfigValue(value="value", secret=True))
preview_response = stack.preview()

The Automation API provides a natural way to orchestrate multiple stacks, feeding the output of one stack as an input to the next as shown in the package-level example below. The package can be used for a number of use cases:

Driving pulumi deployments within CI/CD workflows
Integration testing
Multi-stage deployments such as blue-green deployment patterns
Deployments involving application code like database migrations
Building higher level tools, custom CLIs over pulumi, etc.
Using pulumi behind a REST or GRPC API
Debugging Pulumi programs (by using a single main entrypoint with “inline” programs)

To enable a broad range of runtime customization the API defines a Workspace interface. A Workspace is the execution context containing a single Pulumi project, a program, and multiple stacks. Workspaces are used to manage the execution environment, providing various utilities such as plugin installation, environment configuration ($PULUMI_HOME), and creation, deletion, and listing of Stacks. Every Stack including those in the above examples are backed by a Workspace which can be accessed via:

ws = stack.workspace()
ws.install_plugin("aws", "v3.20.0")

Workspaces can be explicitly created and customized beyond the three Stack creation helpers noted above:

ws = LocalWorkspace(work_dir=os.path.join(".", "project", "path"), pulumi_home="~/.pulumi")
stack = create_stack("org/proj/stack", ws)

A default implementation of workspace is provided as LocalWorkspace. This implementation relies on Pulumi.yaml and Pulumi.[stack].yaml as the intermediate format for Project and Stack settings. Modifying ProjectSettings will alter the Workspace Pulumi.yaml file, and setting config on a Stack will modify the Pulumi.[stack].yaml file. This is identical to the behavior of Pulumi CLI driven workspaces. Custom Workspace implementations can be used to store Project and Stack settings as well as Config in a different format, such as an in-memory data structure, a shared persistent SQL database, or cloud object storage. Regardless of the backing Workspace implementation, the Pulumi SaaS Console will still be able to display configuration applied to updates as it does with the local version of the Workspace today.

The Automation API also provides error handling utilities to detect common cases such as concurrent update conflicts:

try:
    up_response = stack.up()
except ConcurrentUpdateError:
    { /* retry logic here */ }

pulumi.automation.create_stack(stack_name: str, project_name: Optional[str] = None, program: Optional[Callable[], None]] = None, work_dir: Optional[str] = None, opts: Optional[pulumi.automation._local_workspace.LocalWorkspaceOptions] = None) → pulumi.automation._stack.Stack

Creates a Stack with a LocalWorkspace utilizing the specified inline (in process) Pulumi program or the local Pulumi CLI program from the specified workdir.

Inline Programs

For inline programs, the program and project_name keyword arguments must be provided. This program is fully debuggable and runs in process. If no project_settings option is specified, default project settings will be created on behalf of the user. Similarly, unless a work_dir option is specified, the working directory will default to a new temporary directory provided by the OS.

Local Programs

For local programs, the work_dir keyword argument must be provided. This is a way to create drivers on top of pre-existing Pulumi programs. This Workspace will pick up any available Settings files (Pulumi.yaml, Pulumi.[stack].yaml).

Parameters

stack_name – The name of the stack.
project_name – The name of the project - required for inline programs.
program – The inline program - required for inline programs.
work_dir – The directory for a CLI-driven stack - required for local programs.
