Connect to cloud services

Version history
  • CI_JOB_JWT variable for reading secrets from Vault introduced in GitLab 12.10.
  • CI_JOB_JWT_V2 variable to support additional OIDC providers introduced in GitLab 14.7.
  • ID tokens to support any OIDC provider, including HashiCorp Vault, introduced in GitLab 15.7.
CI_JOB_JWT and CI_JOB_JWT_V2 were deprecated in GitLab 15.9 and are scheduled to be removed in GitLab 17.0. Use ID tokens instead.

GitLab CI/CD supports OpenID Connect (OIDC) to give your build and deployment jobs access to cloud credentials and services. Historically, teams stored secrets in projects or applied permissions on the GitLab Runner instance to build and deploy. OIDC capable ID tokens are configurable in the CI/CD job allowing you to follow a scalable and least-privilege security approach.

In GitLab 15.6 and earlier, you must use CI_JOB_JWT_V2 instead of an ID token, but it is not customizable. In GitLab 14.6 an earlier you must use the CI_JOB_JWT, which has limited support.


  • Account on GitLab.
  • Access to a cloud provider that supports OIDC to configure authorization and create roles.

ID tokens support cloud providers with OIDC, including:

  • AWS
  • Azure
  • GCP
  • HashiCorp Vault
Configuring OIDC enables JWT token access to the target environments for all pipelines. When you configure OIDC for a pipeline, you should complete a software supply chain security review for the pipeline, focusing on the additional access. For more information about supply chain attacks, see How a DevOps Platform helps protect against supply chain attacks.

Use cases

  • Removes the need to store secrets in your GitLab group or project. Temporary credentials can be retrieved from your cloud provider through OIDC.
  • Provides temporary access to cloud resources with granular GitLab conditionals including a group, project, branch, or tag.
  • Enables you to define separation of duties in the CI/CD job with conditional access to environments. Historically, apps may have been deployed with a designated GitLab Runner that had only access to staging or production environments. This led to Runner sprawl as each machine had dedicated permissions.
  • Allows shared runners to securely access multiple cloud accounts. The access is determined by the JWT token, which is specific to the user running the pipeline.
  • Removes the need to create logic to rotate secrets by retrieving temporary credentials by default.

How it works

Each job can be configured with ID tokens, which are provided as a CI/CD variable containing the token payload. These JWTs can be used to authenticate with the OIDC-supported cloud provider such as AWS, Azure, GCP, or Vault.

Authorization workflow

sequenceDiagram participant GitLab Note right of Cloud: Create OIDC identity provider Note right of Cloud: Create role with conditionals Note left of GitLab: CI/CD job with ID token GitLab->>+Cloud: Call cloud API with ID token Note right of Cloud: Decode & verify JWT with public key ( Note right of Cloud: Validate audience defined in OIDC Note right of Cloud: Validate conditional (sub, aud) role Note right of Cloud: Generate credential or fetch secret Cloud->>GitLab: Return temporary credential Note left of GitLab: Perform operation
  1. Create an OIDC identity provider in the cloud (for example, AWS, Azure, GCP, Vault).
  2. Create a conditional role in the cloud service that filters to a group, project, branch, or tag.
  3. The CI/CD job includes an ID token which is a JWT token. You can use this token for authorization with your cloud API.
  4. The cloud verifies the token, validates the conditional role from the payload, and returns a temporary credential.

Configure a conditional role with OIDC claims

To configure the trust between GitLab and OIDC, you must create a conditional role in the cloud provider that checks against the JWT. The condition is validated against the JWT to create a trust specifically against two claims, the audience and subject.

  • Audience or aud: Configured as part of the ID token:

        - echo $OIDC_TOKEN
  • Subject or sub: A concatenation of metadata describing the GitLab CI/CD workflow including the group, project, branch, and tag. The sub field is in the following format:

    • project_path:{group}/{project}:ref_type:{type}:ref:{branch_name}
Filter typeExample
Filter to main branchproject_path:mygroup/myproject:ref_type:branch:ref:main
Filter to any branchWildcard supported. project_path:mygroup/myproject:ref_type:branch:ref:*
Filter to specific projectproject_path:mygroup/myproject:ref_type:branch:ref:main
Filter to all projects under a groupWildcard supported. project_path:mygroup/*:ref_type:branch:ref:main
Filter to a Git tagWildcard supported. project_path:mygroup/*:ref_type:tag:ref:1.0
