or

  • MONGODB_URL - mongodb instance url
  • MONGODB_USER - mongodb username
  • MONGODB_PASSWORD - user password

  • MONGODB_RETRY_WRITES - retry writes parameter, true by default

Redis

  • REDIS_URL - redis instance url
  • REDIS_PASSWORD - redis password
  • REDIS_TIMEOUT - redis timeout value, default: 1s

Application

  • SECRET_KEY_BASE - custom key used for stored credentials encryption, Rails documentation

  • SETTINGS__COMMANDS_PREFIX - bot name/prefix for comment commands in merge requests
  • SETTINGS__ANONYMOUS_ACCESS - unauthenticated access to projects page and API resources. Default: true

Access

  • SETTINGS__GITLAB_URL - url of gitlab instance, ex: https://gitlab.com by default
  • SETTINGS__GITLAB_ACCESS_TOKEN - gitlab personal access token with api scope
  • SETTINGS__GITHUB_ACCESS_TOKEN - github personal access token with repository read scope, without it you can run into rate limits when fetching changelog and release notes for all dependencies which code comes from github

Gitlab API

  • SETTINGS__GITLAB_API_MAX_RETRY - max number of retry for each gitlab api call, ex: 5. Default: 3
  • SETTINGS__GITLAB_API_MAX_RETRY_INTERVAL - interval (in seconds) between each retry regarding the gitlab api call, ex: 2. Default: 1

Webhooks

WARNING

Not applicable for standalone mode

  • SETTINGS__DEPENDABOT_URL - url application can be reached on, example: https://dependabot-gitlab.com. This url will be used to automatically add necessary webhooks to project
  • SETTINGS__CREATE_PROJECT_HOOK - enable or disable automated hook creation, default true. This can be useful if the user associated with used access token, does not have maintainer role
  • SETTINGS__GITLAB_AUTH_TOKEN - optional gitlab webhook token which can be configured under webhook settings in gitlab, if not present, token set in gitlab webhook configuration will be ignored

Configuration file

  • SETTINGS__CONFIG_LOCAL_FILENAME - local configuration file location, will be used if no configuration file is found in project repository

    WARNING

    This configuration will be applied to all projects that do not have dependabot.yml configuration file in repository. This can lead to unexpected behavior if you have projects with different package managers and different folder structures.

Service

WARNING

Not applicable for standalone mode

  • SETTINGS__UPDATE_RETRY - amount of retries for dependency update job or false to disable. Default: 2
  • SETTINGS__EXPIRE_RUN_DATA - purge persisted dependency update run logs from database after period of time in seconds, default 1 month

Increasing this value can be useful if worker container is processing a lot of jobs and too small of a value can lead to sidekiq not being able to schedule healtcheck jobs in time. Default: 60
