How to Setup OCI CLI on Linux

This blog shows how to setup OCI CLI on Linux

[root@dev02 ~]# oci setup config
This command provides a walkthrough of creating a valid CLI config file.

The following links explain where to find the information required by this
script:

User API Signing Key, OCID and Tenancy OCID:

https://docs.cloud.oracle.com/Content/API/Concepts/apisigningkey.htm#Other

Region:

https://docs.cloud.oracle.com/Content/General/Concepts/regions.htm

General config documentation:

https://docs.cloud.oracle.com/Content/API/Concepts/sdkconfig.htm

Enter a location for your config [/root/.oci/config]:
Enter a user OCID: ocid1.user.oc1..adfdaaaaq54tehkijdffd2gpshbfgfsfgfgfgfp98dfdfdfdfjwrolhmq7bq
Enter a tenancy OCID: ocid1.tenancy.oc1..aaaaaaaaefb4u5ccdfdfsdfd87d89000901adfdfb2cgqfte2dosmdd5o2q
Enter a region (e.g. ap-melbourne-1, ap-mumbai-1, ap-osaka-1, ap-seoul-1, ap-sydney-1, ap-tokyo-1, ca-montreal-1, ca-toronto-1, eu-amsterdam-1, eu-frankfurt-1, eu-zurich-1, me-jeddah-1, sa-saopaulo-1, uk-gov-london-1, uk-london-1, us-ashburn-1, us-gov-ashburn-1, us-gov-chicago-1, us-gov-phoenix-1, us-langley-1, us-luke-1, us-phoenix-1): ap-mumbai-1
Do you want to generate a new API Signing RSA key pair? (If you decline you will be asked to supply the path to an existing key.) [Y/n]: Y
Enter a directory for your keys to be created [/root/.oci]:
Enter a name for your key [oci_api_key]:
Public key written to: /root/.oci/oci_api_key_public.pem
Enter a passphrase for your private key (empty for no passphrase):
Private key written to: /root/.oci/oci_api_key.pem
Fingerprint: 30:9c:4d:34:5b:36:4c:80:61:2a:62:dd:b8:d5:a5:9d
Config written to /root/.oci/config

If you haven't already uploaded your API Signing public key through the
console, follow the instructions on the page linked below in the section
'How to upload the public key':
