Using CloudFound APIs on IBM Cloud:

To work with the IBM Cloud Services we mostly use the IAM API Keys or Access tokens to authenticate first. In similar way to work with Cloud Foundry (CF) applications and services of IBM Cloud using either cli or API , we have to authenticate first against the logging server and then perform the corresponding actions. Although this looks a straight forward approach, I had come across a bit of difficulty in finding the way to retrieve the CF authentication token using API so that I can retrieve the list of applications. So here I am sharing the instructions which I have followed.

To start with :

Make sure the user has Cloud Foundry Access
Ensure to create IAM API Key on IBM Cloud Console
Find the API end-points for the CF api end-points to authenticate

Retrieve Access Token using API

Using the Login server API Endpoint , retrieve the CF auth token. Make sure to set the region based on the IBM Cloud region where the CF applications are being deployed

https://iam.cloud.ibm.com/cloudfoundry/login/<REGION>/oauth/token'

Example command

curl -u "cf:" -X POST '<REPLACE_LOGIN_SERVER_API_ENDPOINT> ' --data-urlencode 'grant_type=password' --data-urlencode 'username=apikey' --data-urlencode 'password=<API_KEY_Value>'

Replace the REPLACE_LOGIN_SERVER_API_ENDPOINT with following entry for region us-south and replace the API Key value for the password

Example:

curl -u "cf:" -X POST 'https://iam.cloud.ibm.com/cloudfoundry/login/us-south/oauth/token' --data-urlencode 'grant_type=password' --data-urlencode 'username=apikey' --data-urlencode 'password=xxxxxxxxxxxxxxx'

Set Authorization header:

Basic-Auth:

username : “cf:"

Set Body Parameters:

'grant_type=password'

'username=apikey’

'password=<API_KEY_Value>'

Retrieve Access Token using CLI Command

1. Login to IBM Cloud

ibmcloud login

set Org , space ,resource group

2. Set CF API endpoint

ibmcloud target --cf-api api.us-south.cf.cloud.ibm.com

3. Get CF Auth token

ibmcloud cf oauth-token

Now, using the Access token from above,

Retrieve the List of Cloud Foundry Apps

Api end-point to retrieve the applications:
https://api.us-south.cf.cloud.ibm.com/v3/apps/

curl --location --request GET 'https://api.us-south.cf.cloud.ibm.com/v3/apps/' \

> --header 'Authorization: Bearer xxxxxxxxxxx'

Output:
