Secrets

Secrets are a Runhouse resource that provides a simple interface for handling your secrets, such as provider credentials and API keys, across environments. With Runhouse APIs, easily

construct a secret object, based on local variables, files, or environment variables
save new secrets and reload existing ones
set secrets across clusters, environments, and functions

For a more detailed API documentation, you can refer to our Runhouse docs.

Constructing Secrets

Secrets are constructed using the rh.secret or rh.provider_secret factory functions.

import runhouse as rh

Base Secret

Base secrets are constructed with rh.secret, and consist of a values dictionary mapping secret keys to values.

my_secret = rh.secret(name="my_secret", values={"key": "secret_val"})
my_secret.save()
del my_secret

INFO | 2023-12-20 05:59:57.445868 | Saving config for ~/my_secret to: /Users/caroline/.rh/secrets/my_secret.json

my_secret = rh.secret("my_secret")
my_secret.values

INFO | 2023-12-20 05:59:57.772553 | Loading config from local file /Users/caroline/.rh/secrets/my_secret.json

{'key': 'secret_val'}

Provider Secret

Provider secrets are constructed with rh.provider_secret and are associated with a provider type. These can be constructed by passing in a values key-pair mapping, or by providing the local file, or local environment variables associated with the keys, and as a result, have additional functionality such as being able to write to a file or environment variables. There are various supported builtin provider types, such as cluster providers (aws, azure, …), api key based providers (openai, anthropic, …), and ssh keys. These secret classes have default locations (file path or environment variables) that Runhouse will use to extract the secret values from out-of-the-box, if the values are not explicitly provided.

rh.Secret.builtin_providers(as_str=True)

['aws',
 'azure',
 'gcp',
 'github',
 'huggingface',
 'lambda',
 'ssh',
 'sky',
 'anthropic',
 'cohere',
 'langchain',
 'openai',
 'pinecone',
 'wandb']

Compute Providers

Here, we construct a default AWS provider secret. We locally have dummy variables stored in the default path ~/.aws/credentials, and we see that this is automatically set.

!cat ~/.aws/credentials

[default]
aws_access_key_id = ABCD_KEY
aws_secret_access_key = 1234_KEY

# default provider secret for AWS. Will pull in values from expected default configuration when used.
aws_secret = rh.provider_secret("aws")

print(f"extracted path: {aws_secret.path}")
print(f"extracted values: {aws_secret.values}")

extracted path: ~/.aws/credentials
extracted values: {'access_key': 'ABCD_KEY', 'secret_key': '1234_KEY'}

You can also instantiate secrets by directly passing in their secret values (if it isn’t locally set up yet), and optionally save it down locally.

# provider secret constructed from values dictionary, for LambdaLabs.
lambda_secret = rh.provider_secret("lambda", values={"api_key": "lambda_key"})

print(f"values: {lambda_secret.values}")

lambda_secret = lambda_secret.write()
print(f"path: {lambda_secret.path}")

INFO | 2023-12-20 17:37:57.775584 | Secrets already exist in ~/.lambda_cloud/lambda_keys.

values: {'api_key': 'lambda_key'}
path: ~/.lambda_cloud/lambda_keys

Or, you can construct a secret with a non-default path, and Runhouse will extract out the values.

!cat ~/.aws/credentials_custom

[default]
aws_access_key_id = ABCD_KEY_CUSTOM
aws_secret_access_key = 1234_KEY_CUSTOM

aws_secret_custom = rh.provider_secret("aws", path="~/.aws/credentials_custom")

print(f"path: {aws_secret_custom.path}")
print(f"values: {aws_secret_custom.values}")

path: ~/.aws/credentials_custom
values: {'access_key': 'ABCD_KEY_CUSTOM', 'secret_key': '1234_KEY_CUSTOM'}

API Keys

These provider secrets consist of a single API key, associated with a default environment variable key, often PROVIDER_API_KEY. They can be constructed by passing in a values dict mapping api_key to the value, or the value will be inferred from the environment variables. Calling .write() will set the environment variable in the current process.

Secrets from inferred env value:

import os
os.environ["OPENAI_API_KEY"] = "openai_key"

openai_secret = rh.provider_secret("openai")
openai_secret.values

{'api_key': 'openai_key'}

Passing in value to the constructor:

anthropic_secret = rh.provider_secret("anthropic", values={"api_key": "ahthropic_key"})
anthropic_secret.write()

os.environ["ANTHROPIC_API_KEY"]

'ahthropic_key'

SSH Keys

SSH public and private key pairs are another type of supported builtin provider type. Simply pass in provider="ssh" and name=<key>.

!cat ~/.ssh/example

private key values

!cat ~/.ssh/example.pub

public key values

ssh_secret = rh.provider_secret(provider="ssh", name="example")
ssh_secret.values

{'public_key': 'public key valuesn',
 'private_key': 'private key valuesn'}

Sending Secrets

You can directly send secrets to a cluster using the secret.to() API, bulk sync secrets using cluster.sync_secrets(), or by including them as part of a rh.env().

cluster = rh.ondemand_cluster("example-cluster")

`secret.to(system, env)`

lambda_secret.path

'~/.lambda_cloud/lambda_keys'

# path secret
lambda_secret.to(cluster)
rh.file(path=lambda_secret.path, system=cluster).fetch(mode="r", deserialize=False)

rh.env

You can also include a list of secrets in a Runhouse env object. When the env is then sent to a cluster, as part of a function or directly, the secrets will be synced onto the environment as well, and accessible from function and system calls running in the environment.

Saving and Loading Secrets

You can save a secret using the .save() API, and reload a saved secret by calling rh.secret(<name>).

If you are not logged in to your Runhouse account, the secret config will be saved locally.

If you have a Runhouse account, which you can create here or by calling either the runhouse login CLI command or rh.login() Python command, calling .save() will save the resource metadata on Runhouse servers, and the secret values to Hashicorp Vault.

Local Secret

local_secret = rh.provider_secret(provider="lambda", name="lambda_key")
local_secret.save()
del local_secret

INFO | 2023-12-20 06:03:31.257864 | Saving config for ~/lambda_key to: /Users/caroline/.rh/secrets/lambda_key.json

{'api_key': 'lambda_key'}

Den Secret

If you have a Runhouse account, which you can create here or by calling either the runhouse login CLI command or rh.login() Python command, you can save secret to your dashboard. The metadata for the Secret resource, such as the provider, any path or env vars, etc, will be saved into Runhouse Den servers, while the secrets values themselves will be stored securely in Hashicorp Vault.

Login and Logout

The login flow gives you the option to upload locally detected builtin provider secrets, or load down saved-down Vault secrets into your local environment. If loading down new secrets, the location (file or env var) of the new secrets will be logged in your runhouse config yaml at ~/.rh/config.yaml as well. There are some useful APIs as well for seeing which secrets you have locally configured or stored in Vault.

runhouse.login(upload_secrets=True, download_secrets=True)

# or, on CLI:
# runhouse login --sync-secrets

To save a secret to Vault, simply call .save() on the resource. This will save both the values themselves, and relevant metadata such as the path where it is locally stored.

You can manually construct and save a resource, or iterate through one of the lists above.
