Server Secrets

It is possible to provide a token or credentials for a number of external services. These may be used to lift a rate limit or provide access to private resources from a self-hosted instance.

There are two ways of setting secrets:

  1. Via environment variables. This is a good way to set them in a PaaS environment.
DRONE_TOKEN=...
DRONE_ORIGINS="https://drone.example.com"
  1. Via checked-in config/local.yml:
public:
  services:
    drone:
      authorizedOrigins: ['https://drone.example.com']
private:
  drone_token: '...'

For more complex scenarios, configuration files can cascade. See the node-config documentation for details.

Authorized origins

Several of the badges provided by Shields allow users to specify the target URL/server of the upstream instance to use via a query parameter in the badge URL (e.g. https://img.shields.io/nexus/s/com.google.guava/guava?server=https%3A%2F%2Foss.sonatype.org). This supports scenarios where your users may need badges from multiple upstream targets, for example if you have more than one Nexus server.

Accordingly, if you configure credentials for one of these services with your self-hosted Shields instance, you must also specifically authorize the hosts to which the credentials are allowed to be sent. If your self-hosted Shields instance then receives a badge request for a target that does not match any of the authorized origins, one of two things will happen:

  • if credentials are required for the targeted service, Shields will render an error badge.
  • if credentials are optional for the targeted service, Shields will attempt the request, but without sending any credentials.

When setting authorized origins through an environment variable, use a space to separate multiple origins. Note that failing to define authorized origins for a service will default to an empty list, i.e. no authorized origins.

It is highly recommended to use https origins with valid SSL, to avoid the possibility of exposing your credentials, for example through DNS-based attacks.

It is also recommended to use tokens for a service account having the fewest privileges needed for fetching the relevant status information.

Services

Azure DevOps

  • AZURE_DEVOPS_TOKEN (yml: private.azure_devops_token)

An Azure DevOps Token (PAT) is required for accessing private Azure DevOps projects.

Create a PAT using an account that has access to your target Azure DevOps projects. Your PAT only needs the following scopes:

  • Build (read)
  • Release (read)
  • Test Management (read)

Bitbucket (Cloud)

  • BITBUCKET_USER (yml: private.bitbucket_username)
  • BITBUCKET_PASS (yml: private.bitbucket_password)

Bitbucket badges use basic auth. Provide a username and password to give your self-hosted Shields installation access to private repositories hosted on bitbucket.org.

Bitbucket Server

  • BITBUCKET_SERVER_ORIGINS (yml: public.services.bitbucketServer.authorizedOrigins)
  • BITBUCKET_SERVER_USER (yml: private.bitbucket_server_username)
  • BITBUCKET_SERVER_PASS (yml: private.bitbucket_server_password)

Bitbucket badges use basic auth. Provide a username and password to give your self-hosted Shields installation access to a private Bitbucket Server instance.

Discord

Using a token for Dicsord is optional but will allow higher API rates.

  • DISCORD_BOT_TOKEN (yml: discord_bot_token)

Register an application in the Discord developer console. To obtain a token, simply create a bot for your application.

Drone

  • DRONE_ORIGINS (yml: public.services.drone.authorizedOrigins)
  • DRONE_TOKEN (yml: private.drone_token)

The self-hosted Drone API requires authentication. Log in to your Drone instance and obtain a token from the user profile page.

GitHub

  • GITHUB_URL (yml: public.services.github.baseUri)
  • GH_TOKEN (yml: private.gh_token)

Because of GitHub rate limits, you will need to provide a token, or else badges will stop working once you hit 60 requests per hour, the unauthenticated rate limit.

You can create a personal access token through the GitHub website. When you create the token, you can choose to give read access to your repositories. If you do that, your self-hosted Shields installation will have access to your private repositories.

When a gh_token is specified, it is used in place of the Shields token rotation logic.

GITHUB_URL can be used to optionally send all the GitHub requests to a GitHub Enterprise server. This can be done in conjunction with setting a token, though it's not required.

  • GH_CLIENT_ID (yml: private.gh_client_id)
  • GH_CLIENT_SECRET (yml: private.gh_client_secret)

These settings are used by shields.io for GitHub OAuth app authorization but will not be necessary for most self-hosted installations. See production-hosting.md.

Jenkins CI

  • JENKINS_ORIGINS (yml: public.services.jenkins.authorizedOrigins)
  • JENKINS_USER (yml: private.jenkins_user)
  • JENKINS_PASS (yml: private.jenkins_pass)

Provide a username and password to give your self-hosted Shields installation access to a private Jenkins CI instance.

Jira

  • JIRA_ORIGINS (yml: public.services.jira.authorizedOrigins)
  • JIRA_USER (yml: private.jira_user)
  • JIRA_PASS (yml: private.jira_pass)

Provide a username and password to give your self-hosted Shields installation access to a private JIRA instance.

Nexus

  • NEXUS_ORIGINS (yml: public.services.nexus.authorizedOrigins)
  • NEXUS_USER (yml: private.nexus_user)
  • NEXUS_PASS (yml: private.nexus_pass)

Provide a username and password to give your self-hosted Shields installation access to your private nexus repositories.

npm

  • NPM_ORIGINS (yml: public.services.npm.authorizedOrigins)
  • NPM_TOKEN (yml: private.npm_token)

Generate an npm token to give your self-hosted Shields installation access to private npm packages

SymfonyInsight (formerly Sensiolabs)

  • SL_INSIGHT_USER_UUID (yml: private.sl_insight_userUuid)
  • SL_INSIGHT_API_TOKEN (yml: private.sl_insight_apiToken)

The SymfonyInsight API requires authentication. To obtain a token, Create an account, sign in and obtain a uuid and token from your account page.

SonarQube

  • SONAR_ORIGINS (yml: public.services.sonar.authorizedOrigins)
  • SONARQUBE_TOKEN (yml: private.sonarqube_token)

Generate a token to give your self-hosted Shields installation access to a private SonarQube instance or private project on a public instance.

TeamCity

  • TEAMCITY_ORIGINS (yml: public.services.teamcity.authorizedOrigins)
  • TEAMCITY_USER (yml: private.teamcity_user)
  • TEAMCITY_PASS (yml: private.teamcity_pass)

Provide a username and password to give your self-hosted Shields installation access to your private nexus repositories.

Twitch

  • TWITCH_CLIENT_ID (yml: twitch_client_id)
  • TWITCH_CLIENT_SECRET (yml: twitch_client_secret)

Register an application in the Twitch developer console in order to obtain a client id and a client secret for making Twitch API calls.

Weblate

  • WEBLATE_ORIGINS (yml: public.services.weblate.authorizedOrigins)
  • WEBLATE_API_KEY (yml: private.weblate_api_key)

By default Weblate throttles unauthenticated request to only 100 requests per day, after this you will need an API key or else badges will stop working.

You can find your Weblate API key in your profile under "API access".

Wheelmap

  • WHEELMAP_TOKEN (yml: private.wheelmap_token)

The wheelmap API requires authentication. To obtain a token, Create an account, sign in and use the Authentication Token displayed on your profile page.

YouTube

  • YOUTUBE_API_KEY (yml: private.youtube_api_key)

The YouTube API requires authentication. To obtain an API key, log in to a Google account, go to the credentials page, and create an API key for the YouTube Data API v3.

Error reporting

  • SENTRY_DSN (yml: private.sentry_dsn)

A Sentry DSN may be used to send error reports from your installation to Sentry.io. For more info, see the self hosting docs.
