As you can see there, the actual call to trigger a clone or also the termination of an environment is rather simple. I've recently used that a lot when I worked on my clone scripts. In that process, I had to create ~10 clones, and doing so with a simple REST call saved me a lot of time.<\/p>\n In said post, we got hold of a \"OAuth Bearer Token\" that is needed to call those APIs in a very manual way \"through the browser\". In real life, this does not really come in handy. This blog post will describe how a bearer token (including a refresh token) can be received through the command line.<\/p>\n In preparation for using the scripts shown below, we have to enable the usage of \"Device Codes\" for the Cloud Manager application in IDCS:<\/p>\n Furthermore you should take note of the client_id, the client_secret and the IDCS url. All 3 have also been used during Cloud Manager setup.<\/p>\n First of all, the following shell script does all the magic needed. You have to replace XXXXX, YYYYY and ZZZZZ with values from your environment:<\/p>\n When you call this script for the first time, it gives an output as follows:<\/p>\n {\"device_code\":\"xxxxxx\",\"user_code\":\"CTHJNLAM\",\"verification_uri\":\"https:\/\/idcs-ZZZZZ.identity.oraclecloud.com:443\/ui\/v1\/device\",\"expires_in\":300}<\/p>\n identified DEVICE_CODE 483150ce7704487da495593d1c97c2a4 press enter when done<\/p>\n Just open the verification URI provided in a browser, sign in to IDCS and pass the user_code CTHJNLAM.<\/p>\n Then, return to the shell script and press return. This will allow the script to get a Bearer Token including a Refresh token.<\/p>\n On every subsequent run, the \"previous\" refresh token (stored in the file mytoken) is exchanged for an access token and a new refresh token. That new refresh token is saved (each refresh token is a one-time-use token) and can then be used for the next run.<\/p>\n Using the access token we received through that way, we can conveniently access the Cloud Manager APIs.<\/p>\n![](\"\/.\/wp-content\/uploads\/2023\/02\/ACE-Director-Logo_175x51.jpg\"){kind=logo}
