API Connect Backstage Plugin

Installing and using the API Connect Backstage Plugin

Getting the API Connect plugin - clone this repository.

Pre-requisites

• A working, scaffolded Backstage app, installed and configured - see https://backstage.io/docs/getting-started/
• A working PostgresSQL database hooked up to your Backstage install for pesistent data.

Installing the plugin

1. Unpack zip archive in plugins directory

2. From backstage app base path

yarn --cwd packages/backend add apic-backstage@^0.1.0

Configuration the API Connect Plugin

1. For each APIC instance/cloud you wish to configure you need to add name, url, clientId, clientSecret, username, password for a provider organisation in a section at the end of app-config.yaml

ibm:
 schedule: '*/10 * * * *'
 apic:
    - name: apic-instance-1
      url: https://api.<instance1>.com/api
      clientId: '<instance1-clientID>'
      clientSecret: '<instance1-clientSecret>'
      username: '<instance1-porg-user>'
      password: '<instance1-porg-pwd>'
      identityProvider: 'default-idp-2' # Default Local User Registry
    - name: apic-instance-2
      url: https://api.<instance2>.com/api
      clientId: '<instance2-clientID>'
      clientSecret: '<instance2-clientSecret>'
      apiKey: my-api-key

The values for the url, clientId and clientSecret can be found by downloading the toolkit credentials (https://www.ibm.com/docs/en/api-connect/10.0.x?topic=configuration-installing-toolkit#task_qsv_cgq_nt__download_creds)

The url is the value for the "endpoint" for the "toolkit", with the corresponding values for "client_id" mapping to "clientId", and "client_secret" mapping to "clientSecret".

For example the credentials.json for apic-instance-1 in the example above could be:

{
  "cloud_id": "<instance1-cloudID>",
  "toolkit": {
    "endpoint": "https://api.<instance1>com/api",
    "client_id": "<instance1-clientID>",
    "client_secret": "<instance1-clientSecret>"
  },
  "consumer_toolkit": {
    ...
  },
  ...
}

Note: the credentials.json uses snake case, the app-config.yaml API Connect configuration uses camel case.

The username and password or api key are for a provider organization member. For this tech preview it is assumed that there is a single user who is a member of each provider organization to be added to the backstage instance - they should have viewer role for each provider organization at least. This user can also be a member of more than one provider organization.

Using a Local User Registry:

If the user is located in a Local User Registry you will need to provide the identity provider along side the username and password.

Identity Provider can be obtained from running this APIC CLI command:

apic identity-providers:list --scope provider --server myserver.com --fields title,realm

Using an OIDC Registry

When using a user located in a OIDC registry you only need to provide an apiKey. You will need to edit the apiKey lifetime and enable multiple. Instructions on this can be found here https://www.ibm.com/docs/en/api-connect/10.0.8?topic=settings-configuring-api-key

Once you have done this you create an API Key by following the instructions at https://www.ibm.com/docs/en/api-connect/10.0.8?topic=applications-managing-platform-rest-api-keys

Now that you have your add API Key you would just need to add it to your config as shown in the example for apic-instance-2

2. For your Backstage app, edit packages/backend/src/index.ts. Add the following to the end of the file.

backend.add(import('apic-backstage'));

3. Start backstage app

yarn dev

Known Limitations

• only tested with local user registry and oidc.
• do not use capitals or punctuation other than - for the name in the apic config.
