Docker OIDC Action

The official GitHub Action for authenticating to Docker with OIDC.

It exchanges the GitHub-issued OIDC token for your workflow for a short-lived Docker access token — so you can log in to Docker Hub without storing a long-lived password or personal access token as a secret.

Note: The returned token's scope is currently limited to registry login (for example, with docker/login-action). Broader use, such as authenticating to the Docker Hub API, is not supported yet.

Prerequisites

Create an OIDC connection in your Docker organization and note its connection ID. Follow the steps in the Docker documentation.

Usage

The action requires id-token: write permission so the workflow can request a GitHub OIDC token. The exchanged Docker token is returned as the token output and is automatically masked in workflow logs.

jobs:
  build:
    runs-on: ubuntu-latest
    permissions:
      id-token: write # required to request the GitHub OIDC token
    steps:
      - name: Get Docker token
        id: docker_oidc
        uses: docker/oidc-action@v1
        with:
          connection_id: <my-connection-id>

      - name: Log in to Docker Hub
        uses: docker/login-action@v4
        with:
          username: <my-org-name>
          password: ${{ steps.docker_oidc.outputs.token }}
