Nautobot Secrets Providers

Nautobot Secrets Providers is a plugin for Nautobot 1.2.0 or higher that bundles Secrets Providers for integrating with popular secrets backends. Nautobot 1.2.0 added support for integrating with retrieving secrets from various secrets providers.

This plugin publishes secrets providers that are not included in the within the Nautobot core software package so that it will be easier to maintain and extend support for various secrets providers without waiting on Nautobot software releases.

Supported Secrets Backends

This plugin supports the following popular secrets backends:

Secrets Backend	Supported Secret Types	Supported Authentication Methods
AWS Secrets Manager	Other: Key/value pairs	AWS credentials (see Usage section below)
AWS Systems Manager Parameter Store	Other: Key/value pairs	AWS credentials (see Usage section below)
HashiCorp Vault	K/V Version 2 K/V Version 1	Token AppRole AWS Kubernetes
Delinea/Thycotic Secret Server	Secret Server Cloud Secret Server (on-prem)	Access Token Authorization Domain Authorization Password Authorization

Installation

Nautobot Secrets Providers is compatible with Nautobot 1.4.0 and higher. Support for Thycotic Secret Server requires Python 3.7 or later.

The package is available as a Python package in PyPI and can be installed with pip:

pip install nautobot-secrets-providers

You may quickly install all of the dependent libraries using the following command, however, this is not recommended for production deployments as it will install extras that you may not need:

pip install nautobot-secrets-providers[all]

Dependencies

For this plugin to operate you must install at least one of the dependent libraries required by the secrets providers.

You must install the dependencies for at least one of the supported secrets providers or a RuntimeError will be raised.

AWS

AWS Secrets Manager and Systems Manager Parameter Store are supported. Both providers require the boto3 library. This can be easily installed along with the plugin using the following command:

pip install nautobot-secrets-providers[aws]

HashiCorp Vault

The HashiCorp Vault provider requires the hvac library. This can easily be installed along with the plugin using the following command:

pip install nautobot-secrets-providers[hashicorp]

Delinea/Thycotic Secret Server

The Delinea/Thycotic Secret Server provider requires the python-tss-sdk library. This can easily be installed along with the plugin using the following command:

pip install nautobot-secrets-providers[thycotic]

Enabling Secrets Providers

To ensure Nautobot Secrets Providers is automatically re-installed during future upgrades, create a file named local_requirements.txt (if not already existing) in the Nautobot root directory (alongside requirements.txt) and list the secrets package:

echo nautobot-secrets-providers >> local_requirements.txt

Once installed, the plugin needs to be enabled in your nautobot_config.py:

# In your nautobot_config.py
PLUGINS = ["nautobot_secrets_providers"]

# PLUGINS_CONFIG = {
#   "nautobot_secrets_providers": {
#      See below for how to configure Nautobot for each secrets provider!
#   }
# }

Usage

Before you proceed, you must have at least one of the dependent libaries installed as detailed above.

Please do not enable this plugin until you are able to install the dependencies, as it will block Nautobot from starting.

AWS

Authentication

No configuration is needed within Nautobot for this provider to operate. Instead you must provide AWS credentials in one of the methods supported by the boto3 library.

Boto3 credentials can be configured in multiple ways (eight as of this writing) that are mirrored here:

Passing credentials as parameters in the boto.client() method
Passing credentials as parameters when creating a Session object
Environment variables
Shared credential file (~/.aws/credentials)
AWS config file (~/.aws/config)
Assume Role provider
Boto2 config file (/etc/boto.cfg and ~/.boto)
Instance metadata service on an Amazon EC2 instance that has an IAM role configured.

The AWS providers only support methods 3-8. Methods 1 and 2 ARE NOT SUPPORTED at this time.

We highly recommend you defer to using environment variables for your deployment as specified in the credentials documentation linked above. The values specified in the linked documentation should be set within your ~.bashrc (or similar profile) on your system.

Configuration

This is an example based on our recommended deployment pattern in the section above (item 3) that is using environment variables. You will need to set these in the environment prior to starting Nautobot:

export AWS_ACCESS_KEY_ID=foo      # The access key for your AWS account.
export AWS_SECRET_ACCESS_KEY=bar  # The secret key for your AWS account.

Please refer to the Nautobot documentation on updating your .bashrc for how to do this for production Nautobot deployments.

HashiCorp Vault

Configuration

You must provide a mapping in PLUGINS_CONFIG within your nautobot_config.py, for example:

PLUGINS_CONFIG = {
    "nautobot_secrets_providers": {
        "hashicorp_vault": {
            "url": "http://localhost:8200",
            "auth_method": "token",
            "token": os.getenv("NAUTOBOT_HASHICORP_VAULT_TOKEN"),
        }
    },
}

url - (required) The URL to the HashiCorp Vault instance (e.g. http://localhost:8200).
auth_method - (optional / defaults to "token") The method used to authenticate against the HashiCorp Vault instance. Either "approle", "aws", "kubernetes" or "token". For information on using AWS authentication with vault see the authentication section above.
ca_cert - (optional) Path to a PEM formatted CA certificate to use when verifying the Vault connection. Can alternatively be set to False to ignore SSL verification (not recommended) or True to use the system certificates.
default_mount_point - (optional / defaults to "secret") The default mount point of the K/V Version 2 secrets engine within Hashicorp Vault.
kv_version - (optional / defaults to "v2") The version of the KV engine to use, can be v1 or v2
k8s_token_path - (optional) Path to the kubernetes service account token file. Defaults to "/var/run/secrets/kubernetes.io/serviceaccount/token".
token - (optional) Required when "auth_method": "token" or auth_method is not supplied. The token for authenticating the client with the HashiCorp Vault instance. As with other sensitive service credentials, we recommend that you provide the token value as an environment variable and retrieve it with {"token": os.getenv("NAUTOBOT_HASHICORP_VAULT_TOKEN")} rather than hard-coding it in your nautobot_config.py.
role_name - (optional) Required when "auth_method": "kubernetes", optional when "auth_method": "aws". The Vault Kubernetes role or Vault AWS role to assume which the pod's service account has access to.
role_id - (optional) Required when "auth_method": "approle". As with other sensitive service credentials, we recommend that you provide the role_id value as an environment variable and retrieve it with {"role_id": os.getenv("NAUTOBOT_HASHICORP_VAULT_ROLE_ID")} rather than hard-coding it in your nautobot_config.py.
secret_id - (optional) Required when "auth_method": "approle".As with other sensitive service credentials, we recommend that you provide the secret_id value as an environment variable and retrieve it with {"secret_id": os.getenv("NAUTOBOT_HASHICORP_VAULT_SECRET_ID")} rather than hard-coding it in your nautobot_config.py.
login_kwargs - (optional) Additional optional parameters to pass to the login method for approle, aws and kubernetes authentication methods.
namespace - (optional) Namespace to use for the X-Vault-Namespace header on all hvac client requests. Required when the Namespaces feature is enabled in Vault Enterprise.

Delinea/Thycotic Secret Server (TSS)

The Delinea/Thycotic Secret Server plugin includes two providers:

Thycotic Secret Server by ID

This provider uses the Secret ID to specifiy the secret that is selected. The Secret ID is displayed in the browser's URL field if you Edit the data in Thycotic Secret Server.
- Example:
  
  The url is: https://pw.example.local/SecretServer/app/#/secret/**1234**/general
  
  In this example the value for Secret ID is 1234.
Thycotic Secret Server by Path

This provider allows to select the secret by folder-path and secret-name. The path delimiter is a '\'.

The Secret path is displayed as page header when Edit a secret.
- Example:
  
  The header is: NET-Automation > Nautobot > My-Secret
  
  In this example the value for Secret path is \NET-Automation\Nautobot\My-Secret.

Configuration

PLUGINS_CONFIG = {
    "nautobot_secrets_providers": {

Contributing

Pull requests are welcomed and automatically built and tested against multiple version of Python and multiple version of Nautobot through GitHub Actions.

The project is packaged with a light development environment based on docker-compose to help with the local development of the project and to run the tests within GitHub Actions.

The project is following Network to Code software development guidelines and is leveraging:

Black, Pylint, Bandit and pydocstyle for Python linting and formatting.
Django unit test to ensure the plugin is working properly.

Development Environment

The development environment can be used in 2 ways. First, with a local poetry environment if you wish to develop outside of Docker with the caveat of using external services provided by Docker for PostgreSQL and Redis. Second, all services are spun up using Docker and a local mount so you can develop locally, but Nautobot is spun up within the Docker container.

Below is a quick start guide if you're already familiar with the development environment provided, but if you're not familiar, please read the Getting Started Guide.

Invoke

The PyInvoke library is used to provide some helper commands based on the environment. There are a few configuration parameters which can be passed to PyInvoke to override the default configuration:

nautobot_ver: the version of Nautobot to use as a base for any built docker containers (default: 1.4.10)
project_name: the default docker compose project name (default: nautobot_secrets_providers)
python_ver: the version of Python to use as a base for any built docker containers (default: 3.8)
local: a boolean flag indicating if invoke tasks should be run on the host or inside the docker containers (default: False, commands will be run in docker containers)
compose_dir: the full path to a directory containing the project compose files
compose_files: a list of compose files applied in order (see Multiple Compose files for more information)

Using PyInvoke these configuration options can be overridden using several methods. Perhaps the simplest is simply setting an environment variable INVOKE_NAUTOBOT_SECRETS_PROVIDERS_VARIABLE_NAME where VARIABLE_NAME is the variable you are trying to override. The only exception is compose_files, because it is a list it must be overridden in a yaml file. There is an example invoke.yml (invoke.example.yml) in this directory which can be used as a starting point.

Local Poetry Development Environment

Copy development/creds.example.env to development/creds.env (This file will be ignored by Git and Docker)
Uncomment the POSTGRES_HOST, REDIS_HOST, and NAUTOBOT_ROOT variables in development/creds.env
Create an invoke.yml file with the following contents at the root of the repo (you can also cp invoke.example.yml invoke.yml and edit as necessary):

---
nautobot_secrets_providers:
  local: true
  compose_files:
    - "docker-compose.requirements.yml"

Run the following commands:

poetry shell
poetry install --extras nautobot
export $(cat development/dev.env | xargs)
export $(cat development/creds.env | xargs)
invoke start && sleep 5
nautobot-server migrate

If you want to develop on the latest develop branch of Nautobot, run the following command: poetry add --optional git+https://github.com/nautobot/nautobot@develop. After the @ symbol must match either a branch or a tag.

You can now run nautobot-server commands as you would from the Nautobot documentation for example to start the development server:

nautobot-server runserver 0.0.0.0:8080 --insecure

Nautobot server can now be accessed at http://localhost:8080.

It is typically recommended to launch the Nautobot runserver command in a separate shell so you can keep developing and manage the webserver separately.

Docker Development Environment

This project is managed by Python Poetry and has a few requirements to setup your development environment:

Install Poetry, see the Poetry Documentation for your operating system.
Install Docker, see the Docker documentation for your operating system.

Once you have Poetry and Docker installed you can run the following commands to install all other development dependencies in an isolated python virtual environment:

poetry shell
poetry install
invoke start

Nautobot server can now be accessed at http://localhost:8080.

To either stop or destroy the development environment use the following options.

invoke stop - Stop the containers, but keep all underlying systems intact
invoke destroy - Stop and remove all containers, volumes, etc. (This results in data loss due to the volume being deleted)

CLI Helper Commands

The project is coming with a CLI helper based on invoke to help setup the development environment. The commands are listed below in 3 categories dev environment, utility and testing.

Each command can be executed with invoke <command>. Environment variables INVOKE_NAUTOBOT_SECRETS_PROVIDERS_PYTHON_VER and INVOKE_NAUTOBOT_SECRETS_PROVIDERS_NAUTOBOT_VER may be specified to override the default versions. Each command also has its own help invoke <command> --help

Project Documentation

Project documentation is generated by mkdocs from the documentation located in the docs folder. You can configure readthedocs.io to point at this folder in your repo. For development purposes a docker-compose.docs.yml is also included. A container hosting the docs will be started using the invoke commands on http://localhost:8001, as changes are saved the docs will be automatically reloaded.

Developing Against Secrets Backends

AWS Secrets Manager

This assumes you are logged into the AWS Console.

Navigate to AWS Console
Navigate to AWS Secrets Manager
Click "Store a new secret"
- Select “Other type of secrets”
- Use Secret key/value
- Enter hello=world
- Use "DefaultEncryptionKey" for now
- Click "Next"
- Under "Secret name" fill out hello
- Click "Next"
- Under "Configure automatic rotation"
  - Leave it as "Disable automatic rotation"
- On "Store a new secret"
  - Copy the sample code (see below)
- Click "Store"
END

Install the AWS CLI

Next, install the AWS CLI.

On MacOS, this can be done using brew install awscli:

brew install awscli

On Linux, you will need to run a curl command (This assumes x86. Please see the docs for AWS CLI on Linux for ARM and other options):

curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
unzip awscliv2.zip
sudo ./aws/install

Configure the AWS CLI

After installing the AWS CLI, you will need to configure it for authentication.

You may use an existing AWS access key or create a new one. For these instructions we cover the need to create a new access key that can be used for this.

Navigate to AWS Console
Click your username
- Click "My security credentials"
- Click "create access key"
Save your "Access key ID" and "Secret access key" for use when configuring the AWS CLI

Now configure the CLI:

Run aws configure
Enter your credentials from above
Choose your region
Use output format: json

Example:

$ aws configure
AWS Access Key ID [None]: AKIAIOSFODNN7EXAMPLE
AWS Secret Access Key [None]: wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY
Default region name [None]: us-east-2
Default output format [None]: json

Now you are ready to use the sample code to retrieve your secret from AWS Secrets Manager!

Sample Code

Make sure that the boto3 client is installed:

poetry install --extras aws

Next, save this as aws_secrets.py:

# Use this code snippet in your app.
# If you need more information about configurations or implementing the sample code, visit the AWS docs:
# https://aws.amazon.com/developers/getting-started/python/

import boto3
import base64
from botocore.exceptions import ClientError


def get_secret():

    secret_name = "hello"
    region_name = "us-east-2"

    # Create a Secrets Manager client
    session = boto3.session.Session()
    client = session.client(
        service_name='secretsmanager',
        region_name=region_name
    )

    # In this sample we only handle the specific exceptions for the 'GetSecretValue' API.
    # See https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_GetSecretValue.html
    # We rethrow the exception by default.

    try:
        get_secret_value_response = client.get_secret_value(
            SecretId=secret_name
        )
    except ClientError as e:
        if e.response['Error']['Code'] == 'DecryptionFailureException':
            # Secrets Manager can't decrypt the protected secret text using the provided KMS key.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response['Error']['Code'] == 'InternalServiceErrorException':
            # An error occurred on the server side.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response['Error']['Code'] == 'InvalidParameterException':
            # You provided an invalid value for a parameter.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response['Error']['Code'] == 'InvalidRequestException':
            # You provided a parameter value that is not valid for the current state of the resource.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response['Error']['Code'] == 'ResourceNotFoundException':
            # We can't find the resource that you asked for.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
    else:
        # Decrypts secret using the associated KMS CMK.
        # Depending on whether the secret is a string or binary, one of these fields will be populated.
        if 'SecretString' in get_secret_value_response:
            secret = get_secret_value_response['SecretString']
        else:
            decoded_binary_secret = base64.b64decode(get_secret_value_response['SecretBinary'])

    # Your code goes here.

# ^ Above was generated by AWS.

# This was added by us so you can run this as a script:
if __name__ == "__main__":
    secret = get_secret()
    print(f"Secret = {secret}")

Run it with python aws_secrets.py:

$ python aws_secrets.py
Secret = {"hello":"world"}.

Note that this blob is JSON and will also need to be decoded if you want to extract the value.

HashiCorp Vault

Make sure that the hvac client is installed:

poetry install --extras hashicorp

Start Services with Docker

invoke start

Set an alias to work with `vault`

This will allow you to easily run the CLI command from within the container:

alias vault="docker exec -it nautobot_secrets_providers_vault_1 vault"

Interact with the Vault vi CLI (via docker exec into the container from localhost):

$ vault status
Key             Value
---             -----
Seal Type       shamir
Initialized     true
Sealed          false
Total Shares    1
Threshold       1
Version         1.8.2
Storage Type    inmem
Cluster Name    vault-cluster-35c5d319
Cluster ID      2611f99c-a6de-a883-1fcc-bfffdc0217bc
HA Enabled      false

Using the Python `hvac` Library

This establishes a client, creates a basic key/value secret (hello=world) at the path hello, and then retrieves the data from the hello key at the secret path hello.

This is equivalent to the command vault kv get -field hello secret/hello.

In [1]: import hvac

In [2]: client = hvac.Client(url="http://localhost:8200", token="nautobot")

In [3]: client.secrets.kv.create_or_update_secret(path="hello", secret=dict(hello="world"))
Out[3]:
{'request_id': 'c4709868-c08f-4cb1-ab8c-605c58b82f3f',
 'lease_id': '',
 'renewable': False,
 'lease_duration': 0,
 'data': {'created_time': '2021-09-16T23:21:07.5564132Z',
  'deletion_time': '',
  'destroyed': False,
  'version': 2},
 'wrap_info': None,
 'warnings': None,
 'auth': None}

In [4]: client.secrets.kv.read_secret(path="hello")["data"]["data"]["hello"]
Out[4]: 'world'
