Adobe I/O Token Vending Machine (TVM)

This is an implementation of a TVM delivering temporary and restricted tokens to access various cloud services. Users authenticate to the TVM with their Adobe I/O Runtime (a.k.a OpenWhisk) credentials and are only authorized to access their own resources.

Use

curl -H "Authorization: ${AUTH}" "https://adobeio.adobeioruntime.net/apis/tvm/azure/blob/${NAMESPACE}"

API

Endpoints:
- Get AWS S3 token: https://adobeio.adobeioruntime.net/apis/tvm/aws/s3/${owNamespace}
- Get Azure Blob token: https://adobeio.adobeioruntime.net/apis/tvm/azure/blob/${owNamespace}
- Get Azure Cosmos token: https://adobeio.adobeioruntime.net/apis/tvm/azure/cosmos/${owNamespace}
For each of the above endpoints applies:
- HTTP method is GET
- OpenWhisk auth key must be passed in Authorization header
- OpenWhisk namespace must be passed in the url path
Deprecated:
- Get AWS S3 token https://adobeioruntime.net/api/v1/web/adobeio/tvm/get-s3-upload-token is still accessible (POST and GET) with params {"owAuth": "<myauth>", "owNamespace": "<mynamespace>"}

Deploy your own TVM

Why

You want to share a cloud service that you own (e.g 1 S3 account) with a set of OpenWhisk namespaces and you want to make sure that each namespace has access only to the resources they own (e.g can only see their S3 blobs).

This might be useful for you if:

You have multiple Adobe I/O Runtime namespaces and you need them to access a cloud service but you don't want to use the one exposed by Adobe's TVM
You are an OpenWhisk provider and want to provide an easy access to an external cloud service (e.g. storage)

Setup

npm install

Deployment Config

.env:

AIO_RUNTIME_APIVERSION=v1
AIO_RUNTIME_APIHOST=https://adobeioruntime.net
AIO_RUNTIME_NAMESPACE=<deployment_ns>
AIO_RUNTIME_AUTH=<deployment_auth_ns>

EXPIRATION_DURATION=<token expiration in seconds>
WHITELIST=<comma separated list of namespaces>

AWS_ACCESS_KEY_ID=<key id of IAM user created in AWS>
AWS_SECRET_ACCESS_KEY=<secret of IAM user created in AWS>
S3_BUCKET=<MY_BUCKET>

AZURE_STORAGE_ACCOUNT=<storage account name>
AZURE_STORAGE_ACCESS_KEY=<storage access key>

AZURE_COSMOS_ACCOUNT=<cosmosdb account name>
AZURE_COSMOS_MASTER_KEY=<cosmosdb master key>
AZURE_COSMOS_DATABASE_ID=<cosmosdb database name>
AZURE_COSMOS_CONTAINER_ID=<cosmosdb database name>

# for functional tests only
TEST_NAMESPACE_1=<test ns 1>
TEST_AUTH_1=<test auth 1>
TEST_NAMESPACE_2=<test ns 2>
TEST_AUTH_2=<test auth ns 2>

Use the WHITELIST variable to control which namespace can access the TVM and hence who can deploy files to your S3 Bucket.
- [ ⚠️ NOT RECOMMENDED ⚠️] Use WHITELIST=* to allow access to every OpenWhisk namespace in the same domain.

Setup Azure Blob

Create a storage account
Retrieve the access key
Fill AZURE_STORAGE_* variables in .env

Setup Azure CosmosDB

Create a cosmos account
Click on + Add Container:
- specify a database name
- specify a container name
- specify a partitionKey: call it /partitionKey => the name is important
- create the container
Configure the newly created container to have ttl set to on
Retrieve the account master key and set AZURE_COSMOS_MASTER_KEY

Setup AWS S3

Create a Bucket in S3 for your app

Create an IAM user with the following IAM policy in AWS (replace MY_BUCKET with your app bucket name):

  {
    "Version": "2012-10-17",
    "Statement": [
      {
        "Sid": "AllowTokenDelivery",
        "Effect": "Allow",
        "Action": "sts:GetFederationToken",
        "Resource": "*"
      },
      {
        "Sid": "AllowS3",
        "Effect": "Allow",
        "Action": [
            "s3:PutObject",
            "s3:DeleteObject",
            "s3:PutObjectAcl",
            "s3:ListBucket"
        ],
        "Resource": [
          "arn:aws:s3:::MY_BUCKET/*",
          "arn:aws:s3:::MY_BUCKET"
        ]
      }
    ]
  }

Configure the .env file, see config

Deploy the TVM endpoints

npm run deploy will deploy all TVM endpoints to the OpenWhisk namespace configured in .env

Undeploy

npm run undeploy

Release a new version

npm run release will run tests, bump up the version and deploy all TVM endpoints to the OpenWhisk namespace configured in .env.
note: this command will run functional tests and will need you to have additional OpenWhisk test namespaces setup up in your .env (see config)
