Deploying an Authorizer Function

Find out how to deploy an authorizer function for use with API Gateway.

To deploy an authorizer function that you've written:

1. Build a Docker image from the code, push the Docker image to a Docker registry, and create a new function in OCI Functions based on the image. You can do this in different ways:

   • You can use the Fn Project CLI command fn deploy to build a new Docker image, push the image to the Docker registry, and create a new function in OCI Functions based on the image. See Creating and Deploying Functions.
   • You can use Docker commands to build the image and push it to the Docker registry, and then use the Fn Project CLI command fn create function (or the CreateFunction API operation) to create a new function in OCI Functions based on the image. See Creating Functions from Existing Docker Images.
2. Make a note of the OCID of the function you create in OCI Functions. For example, ocid1.fnfunc.oc1.phx.aaaaaaaaac2______kg6fq

3. If one doesn't exist already, create an Oracle Cloud Infrastructure policy and specify a policy statement to give API gateways access to function-related resources. The policy enables API deployments on those API gateways to invoke the authorizer function. For more information, see Create a Policy to Give API Gateways Access to Functions
