Configuring OpenID Connect in JFrog

Overview

OpenID Connect (OIDC) allows your GitHub Actions workflows to authenticate with JFrog to download and publish artifacts without storing JFrog passwords, tokens, or API keys in GitHub.

This guide gives an overview of how to configure JFrog to trust GitHub's OIDC as a federated identity, and demonstrates how to use this configuration in a GitHub Actions workflow.

For an example GitHub Actions workflow, see Sample GitHub Actions Integration in the JFrog documentation.

For an example GitHub Actions workflow using the JFrog CLI, see build-publish.yml in the jfrog-github-oidc-example repository.

Prerequisites

• Para saber os conceitos básicos de como o GitHub usa o OIDC (OpenID Connect), além da arquitetura e dos benefícios, confira "Sobre o enrijecimento de segurança com o OpenID Connect".

• Antes de prosseguir, você deve planejar sua estratégia de segurança para garantir que os tokens de acesso sejam atribuídos apenas de forma previsível. Para controlar como o provedor de nuvem emite os tokens de acesso, você precisa definir, pelo menos, uma condição, para que os repositórios não confiáveis não possam solicitar tokens de acesso aos seus recursos de nuvem. Para obter mais informações, confira "Sobre o enrijecimento de segurança com o OpenID Connect".

• To be secure, you need to set a Claims JSON in JFrog when configuring identity mappings. For more information, see "AUTOTITLE" and "Sobre o enrijecimento de segurança com o OpenID Connect."

  For example, you can set iss to https://token.actions.githubusercontent.com, and the repository to something like "octo-org/octo-repo"`. This will ensure only Actions workflows from the specified repository will have access to your JFrog platform. The following is an example Claims JSON when configuring identity mappings.

  JSON

  {
    "iss": "https://token.actions.githubusercontent.com",
    "repository": "octo-org/octo-repo"
  }
  

Adding the identity provider to JFrog

To use OIDC with JFrog, establish a trust relationship between GitHub Actions and the JFrog platform. For more information about this process, see OpenID Connect Integration in the JFrog documentation.

1. Sign in to your JFrog Platform.
2. Configure trust between JFrog and your GitHub Actions workflows.
3. Configure identity mappings.

Updating your GitHub Actions workflow

Once you establish a trust relationship between GitHub Actions and the JFrog platform, you can update your GitHub Actions workflow file.

In your GitHub Actions workflow file, ensure you are using the provider name and audience you configured in the JFrog Platform.

The following example uses the placeholder YOUR_PROVIDER_NAME.

- name: Fetch Access Token from Artifactory
        id: fetch_access_token
        env:
          ID_TOKEN: $
        run: |
          ACCESS_TOKEN=$(curl \
          -X POST \
          -H "Content-type: application/json" \
          https://example.jfrog.io/access/api/v1/oidc/token \
          -d \
          "{\"grant_type\": \"urn:ietf:params:oauth:grant-type:token-exchange\", \"subject_token_type\":\"urn:ietf:params:oauth:token-type:id_token\", \"subject_token\": \"$ID_TOKEN\", \"provider_name\": \"YOUR_PROVIDER_NAME\"}" | jq .access_token | tr -d '"')
          echo ACCESS_TOKEN=$ACCESS_TOKEN >> $GITHUB_OUTPUT

The following example shows part of a GitHub Actions workflow file using cURL.

- name: Get ID Token (cURL method)
        id: idtoken
        run: |
          ID_TOKEN=$(curl -sLS -H "User-Agent: actions/oidc-client" -H "Authorization: Bearer $ACTIONS_ID_TOKEN_REQUEST_TOKEN" \
          "${ACTIONS_ID_TOKEN_REQUEST_URL}&audience=jfrog-github" | jq .value | tr -d '"')
          echo "ID_TOKEN=${ID_TOKEN}" >> $GITHUB_OUTPUT

Alternatively, you can set the audience as an environment variable using the env context. For more information about the env context, see "Contextos."

jobs:
  build:
    runs-on: ubuntu-latest
    env:
      OIDC_AUDIENCE: 'YOUR_AUDIENCE'

Then, in your workflow file, retrieve the value of the variables stored in the env context. The following example uses the env context to retrieve the OIDC audience.

- name: Get ID Token (using env context)
        uses: actions/github-script@v6
        id: idtoken
        with:
          script: |
            const coredemo = require('@actions/core');
            let id_token = await coredemo.getIDToken(process.env.OIDC_AUDIENCE);
            coredemo.setOutput('id_token', id_token);
