vault-action

A helper action for easily pulling secrets from the K/V backend of vault.

Expects Version 2 of the KV Secrets Engine by default.

Example Usage

jobs:
    build:
        # ...
        steps:
            # ...
            - name: Import Secrets
              uses: RichiCoder1/vault-action
              with:
                url: https://vault.mycompany.com:8200
                token: ${{ secrets.VaultToken }}
                secrets: |
                    ci/aws accessKey | AWS_ACCESS_KEY_ID ;
                    ci/aws secretKey | AWS_SECRET_ACCESS_KEY ;
                    ci npm_token
            # ...

Authentication method

The method parameter can have these value :

• token: (by default) you must provide a token parameter

...
with:
  url: https://vault.mycompany.com:8200
  token: ${{ secrets.VaultToken }}

• approle: you must provide a roleId & secretId parameter

...
with:
  url: https://vault.mycompany.com:8200
  method: approle
  roleId: ${{ secrets.roleId }}
  secretId: ${{ secrets.secretId }}

Key Syntax

The secrets parameter is a set of multiple secret requests separated by the ; character.

Each secret request is comprised of the path and the key of the desired secret, and optionally the desired Env Var output name.

{{ Secret Path }} {{ Secret Key }} | {{ Output Environment Variable Name }}

Simple Key

To retrieve a key npmToken from path ci that has value somelongtoken from vault you could do:

with:
    secrets: ci npmToken

vault-action will automatically normalize the given data key, and output:

NPMTOKEN=somelongtoken

Set Environment Variable Name

However, if you want to set it to a specific environmental variable, say NPM_TOKEN, you could do this instead:

with:
    secrets: ci npmToken | NPM_TOKEN

With that, vault-action will now use your requested name and output:

NPM_TOKEN=somelongtoken

Multiple Secrets

This action can take multi-line input, so say you had your AWS keys stored in a path and wanted to retrieve both of them. You can do:

with:
    secrets: |
        ci/aws accessKey | AWS_ACCESS_KEY_ID ;
        ci/aws secretKey | AWS_SECRET_ACCESS_KEY

Using K/V version 1

By default, vault-action expects a K/V engine using version 2.

In order to work with a v1 engine, the kv-version parameter may be passed:

with:
    kv-version: 1

Custom Engine Path

When you enable the K/V Engine, by default it's placed at the path secret, so a secret named ci will be accessed from secret/ci. However, if you enabled the secrets engine using a custom path, you can pass it as follows:

with:
    path: my-secrets
    secrets: ci npmToken

This way, the ci secret in the example above will be retrieved from my-secrets/ci.

Namespace

This action could be use with namespace Vault Enterprise feature. You can specify namespace in request :

steps:
    # ...
    - name: Import Secrets
      uses: RichiCoder1/vault-action
      with:
        url: https://vault-enterprise.mycompany.com:8200
        method: token
        token: ${{ secrets.VaultToken }}
        namespace: ns1
        secrets: |
            ci/aws accessKey | AWS_ACCESS_KEY_ID ;
            ci/aws secretKey | AWS_SECRET_ACCESS_KEY ;
            ci npm_token

Masking

This action uses Github Action's built in masking, so all variables will automatically be masked if printed to the console or to logs.
