for your local Ubuntu Desktop Machine make a directory ocikeys and run following commands inside it
REMEMBER the url for .PEM file we would need this file later
/home/oracle/kube/ocikeys/oci_api_key.pem
oracle@oracle:~/kube/ocikeys$ openssl genrsa -out oci_api_key.pem 2048 Generating RSA private key, 2048 bit long modulus ................+++ ..........................................................+++ e is 65537 (0x010001) oracle@oracle:~/kube/ocikeys$ openssl rsa -pubout -in oci_api_key.pem -out oci_api_key_public.pem writing RSA key oracle@oracle:~/kube/ocikeys$ oracle@oracle:~/kube/ocikeys$ ls oci_api_key.pem oci_api_key_public.pem
Now should now open .pem file in a text pad and copy paste
