What?

Vault Secrets Plugin for Vercel allows you to dynamically generate Vercel API tokens through Vault.

Why?

It is useful for more advanced CI/CD use cases where the common Vercel git integration is not being utilised. That is, Vercel might not even have access to your VCS and you will need to push instead of pull.

With this plugin, the CI/CD pipeline should:

Authenticate to Vault through a number of means. See hashicorp/vault-action docs for full list of available methods, such as:
- AppRole
- JWT OIDC
- A pre-defined token
Call the plugin to generate a short-lived Vercel token. TTL and scope (Vercel team) for the token are user-configurable.
Run the actual deployment pipeline, such as Github Actions for Vercel
After token lifetime runs out, Vault revokes the token automatically.

Example

Here's a full example of a Github Actions pipeline utilising this plugin:

name: Vercel Preview Deployment
env:
  VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }}
  VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }}
on:
  push:
    branches-ignore:
      - main

jobs:
  Deploy-Preview:
    runs-on: ubuntu-latest
    steps:
      - name: Import Secrets
        id: secrets
        uses: hashicorp/vault-action@65d7a12a8098b0aa7fcfdf22ad850c051f8b3ccb # v2.7.2
        with:
          url: ${{ secrets.VAULT_ADDR }}
          method: approle
          roleId: ${{ secrets.VAULT_ROLE_ID }}
          secretId: ${{ secrets.VAULT_SECRET_ID }}
          secrets: |
            vercel-secrets/token bearer_token | VERCEL_TOKEN

      - uses: actions/checkout@c85c95e3d7251135ab7dc9ce3241c5835cc595a9 # v3.5.3

      - name: Install Vercel CLI
        run: npm install --global vercel@latest

      - name: Pull Vercel Environment Information
        run: vercel pull --yes --environment=preview --token=${{ steps.secrets.outputs.VERCEL_TOKEN }}

      - name: Build Project Artifacts
        run: vercel build --token=${{ steps.secrets.outputs.VERCEL_TOKEN }}

      - name: Deploy Project Artifacts to Vercel
        run: vercel deploy --prebuilt --token=${{ steps.secrets.outputs.VERCEL_TOKEN }}

Project scope

Currently this project is scoped for "Hobby" and "Pro" Vercel accounts. This means you can create tokens that:

Hobby: have full admin level access to your Vercel account.
Pro: have project-level access only. Applicable when token creation request is provided with the Token ID parameter.

Enterprise plan features, such as these, are currently scoped out:

Granular token-specific permissions

I don't have an Enterprise plan at hand. Contributions are welcome, of course!
