Verifying Your Configuration for Function Development
Before using Oracle Functions, it's a good idea to confirm that you have successfully completed the prerequisite steps for using Oracle Functions as described in Preparing for Functions and the Functions QuickStart Guides. Specifically, that you have:
- set up your tenancy (see Tenancy Configuration Notes for Oracle Functions)
- set up your development environment (see Client Environment Configuration Notes for Oracle Functions)
If you have successfully completed the configuration tasks, the Fn Project CLI will be able to communicate with the API endpoint.
To confirm that the Fn Project CLI can communicate with the API endpoint:
-
Log in to your development environment as a functions developer.
-
In a terminal window, try and view a list of applications that have been defined in Oracle Functions by entering:
fn list apps -
If you see either of the following, you can proceed to create and deploy functions because your system is configured correctly:
- A message indicating that no applications have been found, which is expected if this is the first time the tenancy has been configured for Oracle Functions.
- A list of applications that have already been created, which is expected if other users are already using the tenancy for functions development.
-
If you see an error message, it's likely that the Fn Project CLI cannot communicate with the API endpoint due to some incorrect configuration. Do the following:
- Review the configuration tasks to confirm you completed them as instructed (see Functions QuickStart Guides, Tenancy Configuration Notes for Oracle Functions, and Client Environment Configuration Notes for Oracle Functions).
- Review the solutions for common problems (see Troubleshooting Oracle Functions).
