Invokes a function


oci fn function invoke [OPTIONS]

Required Parameters

--body [text]

The body of the function invocation. Note: The maximum size of the request is limited. This limit is currently 6MB and the endpoint will not accept requests that are bigger than this limit.

--file [filename]

The name of the file that will receive the response data, or ‘-‘ to write to STDOUT.

--function-id [text]

The OCID of this function.

Optional Parameters

--fn-intent [text]

An optional intent header that indicates to the FDK the way the event should be interpreted. E.g. ‘httprequest’, ‘cloudevent’.

Accepted values are:

cloudevent, httprequest
--fn-invoke-type [text]

Indicates whether Oracle Functions should execute the request and return the result (‘sync’) of the execution, or whether Oracle Functions should return as soon as processing has begun (‘detached’) and leave result handling to the function.

Accepted values are:

detached, sync
--from-json [text]

Provide input to this command as a JSON document from a file using the file://path-to/file syntax.

The --generate-full-command-json-input option can be used to generate a sample json file to be used with this command option. The key names are pre-populated and match the command option names (converted to camelCase format, e.g. compartment-id –> compartmentId), while the values of the keys need to be populated by the user before using the sample file as an input to this command. For any command option that accepts multiple values, the value of the key can be a JSON array.

Options can still be provided on the command line. If an option exists in both the JSON document and the command line then the command line specified value will be used.

For examples on usage of this option, please see our “using CLI with advanced JSON options” link:

Example using required parameter

Copy and paste the following example into a JSON file, replacing the example parameters with your own.

    oci fn application create --generate-param-json-input subnet-ids > subnet-ids.json

Copy the following CLI commands into a file named Run the command by typing “bash” and replacing the example parameters with your own.

Please note this sample will only work in the POSIX-compliant bash-like shell. You need to set up the OCI configuration and appropriate security policies before trying the examples.
