fn list context
fn create context eu-frankfurt-1 --provider oracle
fn use context eu-frankfurt-1
fn update context oracle.compartment-id ocid1.compartment.oc1..aaaaaaaa2nxjnqpnaafi3ybwvifgg3mzpgrdztpp6ehk6gmg4w5bvasbst6q
fn update context api-url https://functions.eu-frankfurt-1.oraclecloud.com
fn update context registry fra.ocir.io/oraseemeaceeociworkshop/ivandelic/fn/techdata-demo

Create Application in Console

fn create app <app-name> --annotation oracle.com/oci/subnetIds='["<subnet-ocid>"]'
fn create app metropole-app --annotation oracle.com/oci/subnetIds='["ocid1.subnet.oc1.eu-frankfurt-1.aaaaaaaavvofj2w65vvttuklkvg33zv77a7566hienkj5s32lwwrpgvqrbvq"]'
