Oracle Cloud native functions - create application from cli
Download as PPTX, PDF0 likes276 views
This document outlines the process for creating applications using Oracle Cloud Functions from the command line interface (CLI). It emphasizes that the information provided is for guidance only and should not be relied upon for purchasing decisions. Additionally, it details the steps required to configure the environment and deploy a serverless function application named 'neptune'.

[root@fnproject neptune]# fn create app neptune --annotation oracle.com/oci/subnetIds='["…ID1…","…ID2…","…ID3…"]'
Successfully created app: neptune
[root@fnproject neptune]#
[root@fnproject neptune]#
Step 1 :
• create the application named “neptune” using “fn create app”
• Ensure to replace …ID1… / …ID2… / …ID3… with the appropriate IDs of the subnets you want to use in OCI
