# CyberArk Ansible Conjur Collection This collection contains components to be used with CyberArk Conjur & Conjur Enterprise hosted in [Ansible Galaxy](https://galaxy.ansible.com/cyberark/conjur). ## Table of Contents * [Certification Level](#certification-level) * [Requirements](#requirements) * [Installation](#installation) * [Conjur Ansible Role](#conjur-ansible-role) + [Usage](#usage) + [Role Variables](#role-variables) + [Example Playbook](#example-playbook) + [Summon & Service Managers](#summon---service-managers) + [Recommendations](#recommendations) * [Conjur Ansible Lookup Plugin](#conjur-ansible-lookup-plugin) + [Environment variables](#environment-variables) + [Role Variables](#role-variables-1) + [Examples](#examples) - [Retrieve a secret in a Playbook](#retrieve-a-secret-in-a-playbook) - [Retrieve a private key in an Inventory file](#retrieve-a-private-key-in-an-inventory-file) * [Contributing](#contributing) * [License](#license) <!-- Table of contents generated with markdown-toc http://ecotrust-canada.github.io/markdown-toc/ --> ## Certification Level ![](https://img.shields.io/badge/Certification%20Level-Certified-6C757D?link=https://github.com/cyberark/community/blob/main/Conjur/conventions/certification-levels.md) This repo is a **Certified** level project. It's been reviewed by CyberArk to verify that it will securely work with CyberArk Enterprise as documented. In addition, CyberArk offers Enterprise-level support for these features. For more detailed information on our certification levels, see [our community guidelines](https://github.com/cyberark/community/blob/main/Conjur/conventions/certification-levels.md#community). ## Requirements - An instance of [CyberArk Conjur Open Source](https://www.conjur.org) v1.x+ or [CyberArk Conjur Enterprise](https://docs.cyberark.com/Product-Doc/OnlineHelp/AAM-DAP/Latest/en/Content/Resources/_TopNav/cc_Home.htm) (formerly DAP) v10.x+ accessible from the target node - Ansible >= 2.9 ## Using ansible-conjur-collection with Conjur Open Source Are you using this project with [Conjur Open Source](https://github.com/cyberark/conjur)? Then we **strongly** recommend choosing the version of this project to use from the latest [Conjur OSS suite release](https://docs.conjur.org/Latest/en/Content/Overview/Conjur-OSS-Suite-Overview.html). Conjur maintainers perform additional testing on the suite release versions to ensure compatibility. When possible, upgrade your Conjur version to match the [latest suite release](https://docs.conjur.org/Latest/en/Content/ReleaseNotes/ConjurOSS-suite-RN.htm); when using integrations, choose the latest suite release that matches your Conjur version. For any questions, please contact us on [Discourse](https://discuss.cyberarkcommons.org/c/conjur/5). ## Installation From terminal, run the following command: ```sh ansible-galaxy collection install cyberark.conjur ``` ## Conjur Ansible Role This Ansible role provides the ability to grant Conjur machine identity to a host. Based on that identity, secrets can then be retrieved securely using the [Conjur Lookup Plugin](#conjur-ansible-lookup-plugin) or using the [Summon](https://github.com/cyberark/summon) tool (installed on hosts with identities created by this role). ### Usage The Conjur role provides a method to establish the Conjur identity of a remote node with Ansible. The node can then be granted least-privilege access to retrieve the secrets it needs in a secure manner. ### Role Variables * `conjur_appliance_url` _(Required)_: URL of the running Conjur service * `conjur_account` _(Required)_: Conjur account name * `conjur_host_factory_token` _(Required)_: [Host Factory](https://developer.conjur.net/reference/services/host_factory/) token for layer enrollment. This should be specified in the environment on the Ansible controlling host. * `conjur_host_name` _(Required)_: Name of the host to be created. * `conjur_ssl_certificate`: Public SSL certificate of the Conjur endpoint * `conjur_validate_certs`: Boolean value to indicate if the Conjur endpoint should validate certificates * `state`: Specifies whether to install of uninstall the Role on the specified nodes * `summon.version`: version of Summon to install. Default is `0.8.2`. * `summon_conjur.version`: version of Summon-Conjur provider to install. Default is `0.5.3`. The variables not marked _`(Required)`_ are required for running with an HTTPS Conjur endpoint. ### Example Playbook Configure a remote node with a Conjur identity and Summon: ```yml - hosts: servers roles: - role: cyberark.conjur.conjur_host_identity conjur_appliance_url: 'https://conjur.myorg.com' conjur_account: 'myorg' conjur_host_factory_token: "{{ lookup('env', 'HFTOKEN') }}" conjur_host_name: "{{ inventory_hostname }}" conjur_ssl_certificate: "{{ lookup('file', '/path/to/conjur.pem') }}" conjur_validate_certs: yes ``` This example: - Registers the host `{{ inventory_hostname }}` with Conjur, adding it into the Conjur policy layer defined for the provided host factory token. - Installs Summon with the Summon Conjur provider for secret retrieval from Conjur. ### Role Cleanup Executing the following playbook will clean up configuration and identity files written to the specified remote nodes, as well as uninstalling Summon and the Summon Conjur provider: ```yml - hosts: servers roles: - role: cyberark.conjur.conjur_host_identity state: absent ``` ### Summon & Service Managers With Summon installed, using Conjur with a Service Manager (like systemd) becomes a snap. Here's a simple example of a `systemd` file connecting to Conjur: ```ini [Unit] Description=DemoApp After=network-online.target [Service] User=DemoUser #Environment=CONJUR_MAJOR_VERSION=4 ExecStart=/usr/local/bin/summon --yaml 'DB_PASSWORD: !var staging/demoapp/database/password' /usr/local/bin/myapp ``` > Note: When connecting to Conjur 4 (Conjur Enterprise), Summon requires the environment variable `CONJUR_MAJOR_VERSION` set to `4`. You can provide it by uncommenting the relevant line above. The above example uses Summon to retrieve the password stored in `staging/myapp/database/password`, set it to an environment variable `DB_PASSWORD`, and provide it to the demo application process. Using Summon, the secret is kept off disk. If the service is restarted, Summon retrieves the password as the application is started. ### Recommendations - Add `no_log: true` to each play that uses sensitive data, otherwise that data can be printed to the logs. - Set the Ansible files to minimum permissions. Ansible uses the permissions of the user that runs it. ## Conjur Ansible Lookup Plugin Fetch credentials from CyberArk Conjur using the controlling host's Conjur identity or environment variables. The controlling host running Ansible must have a Conjur identity, provided for example by the [ConjurAnsible role](#conjur-ansible-role). ### Environment variables The following environment variables will be used by the lookup plugin to authenticate with the Conjur host, if they are present on the system running the lookup plugin. - `CONJUR_ACCOUNT` : The Conjur account name - `CONJUR_APPLIANCE_URL` : URL of the running Conjur service - `CONJUR_CERT_FILE` : Path to the Conjur certificate file - `CONJUR_AUTHN_LOGIN` : A valid Conjur host username - `CONJUR_AUTHN_API_KEY` : The api key that corresponds to the Conjur host username - `CONJUR_AUTHN_TOKEN_FILE` : Path to a file containing a valid Conjur auth token ### Role Variables None. ### Examples #### Retrieve a secret in a Playbook ```yaml --- - hosts: localhost tasks: - name: Lookup variable in Conjur debug: msg: "{{ lookup('cyberark.conjur.conjur_variable', '/path/to/secret') }}" ``` #### Retrieve a private key in an Inventory file ```yaml --- ansible_host: <host> ansible_ssh_private_key_file: "{{ lookup('cyberark.conjur.conjur_variable', 'path/to/secret-id', as_file=True) }}" ``` **Note:** Using the `as_file=True` condition, the private key is stored in a temporary file and its path is written in `ansible_ssh_private_key_file`. ## Contributing We welcome contributions of all kinds to this repository.
