Interactions with the dashboard#

The public API follows the dashboard settings on the following topics:

  • Filepath banlist
  • Disabled/Enabled detectors
  • Ignored incidents
  • Activated/de-activated validity checks for secrets

Hence when using ggshield you won't get warnings about incidents you've already ignored on the dashboard, incidents of detectors you have disabled and incidents present in files that match ignore patterns on the dashboard. For the same reason if the validity checks have been disabled in the dashboard this information won't be returned in ggshield's output.
Another way to tie ggshield and the dashboard together is the --ignore-known-secrets option that will make ggshield ignore secrets already known in the dashboard.

General Configuration#

When it comes to configuration, ggshield's behavior can be fine-tuned using three sources of parameters.
From higher priority to lower priority:

  • CLI options
  • Environment variables
  • Configuration files This means that CLI options override environment variables which in turn override settings set in configuration files.

CLI options#

A few configuration parameters are available as CLI options. We recommend using --help with the command you intend to use to get more insights on what behaviors can be configured this way.

Environment Variables#

Some of ggshield's behaviors can be tuned via environment variables. When starting-up, ggshield will attempt to load environment variables from different environment files in the following order:

  • the file pointed by the GITGUARDIAN_DOTENV_PATH environment variable.
  • A .env file at the current working directory.
  • A .env file at the root of the current git directory.

Only one of the env files will be loaded out of the three.

List of supported environment variables#

  • GITGUARDIAN_API_KEY: API Key for the GitGuardian API. Use this if you don't want to use the ggshield auth commands.

  • GITGUARDIAN_INSTANCE: Custom URL of the GitGuardian dashboard. The API URL will be inferred from it.

  • GITGUARDIAN_DONT_LOAD_ENV: If set to any value then environment variables won't be loaded from a file.

  • GITGUARDIAN_DOTENV_PATH: If set to a path, ggshield will attempt to load the environment from the specified file.

  • GITGUARDIAN_TIMEOUT: If set to a float, ggshield secret scan pre-receive will timeout after the specified value. Set to 0 to disable the timeout.

  • GITGUARDIAN_MAX_COMMITS_FOR_HOOK: If set to an int, ggshield secret scan pre-receive and ggshield secret scan pre-push will not scan more than the specified value of commits in a single scan.

  • GITGUARDIAN_CRASH_LOG: If set to True, ggshield will display a full traceback when crashing.

Configuration files#

Configuration files selection in ggshield follows a global to local hierarchy.

ggshield will first search for a global config file in the user's home directory:

  • ~/.gitguardian.yml on Linux or MacOS
  • %USERPROFILE%\.gitguardian.yaml on Windows

ggshield will then recognize a local config file in the current working directory (i.e.: ./.gitguardian.yml).

Alternatively, the --config-path option can be used on the main command to specify a custom config file. In this case, neither local nor global config files will be evaluated (example: ggshield --config-path=~/Desktop/custom_config.yaml secret scan path -r .)

A sample config file can be found hereunder:

# Required, otherwise ggshield considers the file to use the deprecated v1 formatversion: 2
# Set to true if the desired exit code for the CLI is always 0, otherwise the# exit code will be 1 if incidents are found.exit-zero: false # default: false
verbose: false # default: false

# Maximum commits to scan in a hook.max-commits-for-hook: 50 # default: 50
# Accept self-signed certificates for the API.allow-self-signed: false # default: false
secret:  # Exclude files and paths by globbing  ignored-paths:    - '**/'    - 'doc/*'    - 'LICENSE'

  show-secrets: false # default: false
  # Detectors to ignore.  ignored-detectors: # default: []    - Generic Password

Specificities for on-premise configuration#

ggshield can also be configured to run on your on-premise GitGuardian instance.

First, you need to point ggshield to your instance, by either defining the instance key in your .gitguardian.yaml configuration file or by defining the GITGUARDIAN_INSTANCE environment variable.

Then, you need to authenticate against your instance, by either using the ggshield auth login --instance https://mygitguardianinstance.mycorp.local command using the --instance option or by obtaining an API key from your dashboard administrator and storing it in the GITGUARDIAN_API_KEY environment variable.
