8 OCI Console 8

9 Setting up your Credentials Keys and OCIDs Make an RSA public/private key pair in PEM format Get the fingerprint of your RSA key Get your tenancy OCID and user OCID Set up your local environment variables to run terraform 9

10 Make the Keys # make the private key openssl genrsa -out ~/.oci/oci_api_key.pem 2048 chmod go-rwx ~/.oci/oci_api_key.pem # make the public key from the private key openssl rsa -pubout -in ~/.oci/oci_api_key.pem -out ~/.oci/oci_api_key_public.pem # copy the public key to the clipboard cat ~/.oci/oci_api_key_public.pem pbcopy # get the key's fingerprint openssl rsa -pubout -outform DER -in ~/.oci/oci_api_key.pem openssl md5 -c 10

11 Get the Tenancy OCID 11

12 Get the Tenancy OCID 12
