Configuration

Watchmaker is configured using a YAML file. Watchmaker's default config.yaml file should work out-of-the-box for most systems and environments. You can also use it as an example to create your own configuration file. The default config file will install Salt and use the bundled Salt formulas to harden the system according to the DISA STIG.

The configuration is a dictionary. The parent nodes (keys) are: all, linux, or windows. The parent nodes contain a list of workers to execute, and each worker contains parameters specific to that worker. The all node is applied to every system, and linux and windows are applied only to their respective systems.

You can create a file using the above format with your own set of standard values and use that file for Watchmaker. Pass the CLI parameter --config to point to that file.

Config.yaml Parent Nodes

all

Section for Worker configurations that affect the deployment of all platforms. The all section will override parameters that are set in the OS-specific sections of config.yaml.

linux

Section for Worker configurations that should only be applied to Linux-based systems.

windows

Section for Worker configurations that should only be applied to Windows-based systems.

Config.yaml Worker Nodes

Watchmaker includes the workers listed below. See the corresponding sections for details on their configuration parameters.

salt worker

Parameters supported by the Salt Worker:

  • admin_groups (list): The group(s) that you would like the admin accounts placed within.

  • admin_users (list): The user(s) that would be created as admins.

  • computer_name (string): The computer or hostname that should be applied.

  • environment (string): Set for the environment in which the system is being built.

  • ou_path (string): Specifies the full DN of the OU where the computer account will be created when joining a domain.

    ou_path: "OU=Super Cool App,DC=example,DC=com"

  • salt_states (string, comma-separated): User-defined salt states to apply.

    salt_states: foo,bar

  • exclude_states (string, comma-separated): States to exclude from execution of salt states.

  • user_formulas (dict): Map of formula names and URLs to zip archives of salt formulas. These formulas will be downloaded, extracted, and added to the salt file roots. The zip archive must contain a top-level directory that, itself, contains the actual salt formula. To "overwrite" bundled submodule formulas, make sure the formula name matches the submodule name.

    user_formulas:
  foo-formula: https://path/to/foo.zip

  • salt_debug_log (string): Path to the debug logfile that salt will write to.

  • salt_content (string): URL to the Salt content file that contains further configuration specific to the salt install.

  • install_method (string): (Linux-only) The method used to install Salt. Currently supports: yum, git

  • bootstrap_source (string): (Linux-only) URL to the salt bootstrap script. This is required if install_method is set to git.

  • git_repo (string): (Linux-only) URL to the salt git repo. This is required if install_method is set to git.

  • salt_version (string): (Linux-only) A git reference present in git_repo, such as a commit or a tag. If not specifid, the HEAD of the default branch will be used. installer_url (string): (Windows-only) URL to the Salt Minion installer for Windows.

yum worker (linux-only)

Parameters supported by the Yum Worker:

  • repo_map (list of maps): There be dragons here! Please be careful making changes to the default config. Thoroughly test your configuration. The default config specifies yum repos that contain the salt-minion. If the default repos are not included, and the salt-minion is not available, the Salt Worker will fail. You can add repos here that you would like enabled, but be wary of removing the default repos. Each map must contain the following keys:

    • dist (list): Distributions that would install this repo. Some repos are supported by multiple distros. (Currently supported distros are redhat, centos, and amazon.)
    • el_version (_string_): The Enterprise Linux version for this repo, as in el6 or el7. Expected values are '6' or '7'.
    • url (string): URL location of the repo file to be added to the system. This file will be copied to /etc/yum.repos.d/

    Example:

    repo_map:
  - dist:
      - redhat
      - centos
    el_version: 6
    url: http://someplace.com/my.repo
