In the previous article A step by step guide to install and configure OCI client the oci client configuration.

OCI provides also token access. 

~ > oci session authenticate --profile-name MY_SESS_PROF --region eu-zurich-1 --tenancy-name <your tenancy name>

Config written to: /Users/mytest/.oci/config

    Try out your newly created session credentials with the following example command:

    oci iam region list --config-file /Users/mytest/.oci/config --profile MY_SESS_PROF --auth security_token

Note: The tenancy name can be found on the page “Tenancy details“

Let’s try out the OCI output suggestion: 

oci iam region list --config-file /Users/mytest/.oci/config --profile MY_SESS_PROF --auth security_token

{
  "data": [
    {
      "key": "AMS",
      "name": "eu-amsterdam-1"
    },
    {
      "key": "ARN",
      "name": "eu-stockholm-1"
    },
......

The $HOME/.config file was updated with the token and the session parameters are in the session directory as follows: 

~ > cd $HOME/.oci
.oci > tree
.
├── config
├── oci_api_key.pem
├── oci_api_key_public.pem
├── rsa.private
├── rsa.public
└── sessions
    └── MY_SESS_PROF
        ├── oci_api_key.pem
        ├── oci_api_key_public.pem
        └── token

.oci > cat config

For an easy use these env variables are available to avoid passing --profile and --auth parameters on oci command line:

~ > export OCI_CLI_PROFILE=MY_SESS_PROF
~ > export OCI_CLI_AUTH=security_token

Token validation: 

~ > oci session validate  --profile MY_SESS_PROF --auth security_token
Session is valid until 2022-10-06 17:59:00

The token can be refreshed before it’s expiration:

~ > oci session refresh --profile MY_SESS_PROF
Attempting to refresh token from https://auth.eu-zurich-1.oraclecloud.com/v1/authentication/refresh
Successfully refreshed token
~ > oci session validate  --profile MY_SESS_PROF --auth security_token
Session is valid until 2022-10-06 18:16:42
