Set up an Oracle Cloud Infrastructure API Signing Key for Use with Oracle Functions:
Before using Oracle Functions, you have to set up an Oracle Cloud Infrastructure API signing key.
The instructions in this topic assume:
- you are using Linux
For more information and other options, see Required Keys and OCIDs.
The instructions below describe how to create a new ~/.oci directory, how to generate a new private key file and public key file in that ~/.oci directory, how to upload the public key to Oracle Cloud Infrastructure to create a new API signing key, and how to obtain a fingerprint for the public API key. Be aware that instructions and examples elsewhere in this documentation assume the ~/.oci directory exists and contains the private and public key files.
To set up an API signing key:
Log in to your development environment as a functions developer.
In a terminal window, confirm that the ~/.oci directory does not already exist. For example, by entering:
ls ~/.oci
Assuming the ~/.oci directory does not already exist, create it. For example, by entering:
mkdir ~/.oci
Generate a private key encrypted with a passphrase that you provide by entering:
$ openssl genrsa -out ~/.oci/<private-key-file-name>.pem -aes128 2048
where <private-key-file-name> is a name of your choice for the private key file (for example, john_api_key_private.pem).
For example:
$ openssl genrsa -out ~/.oci/john_api_key_private.pem -aes128 2048
Generating RSA private key, 2048 bit long modulus
