OpenWhisk - Invoke

Invokes deployed function. It allows to send event data to the function, read logs and display other important information of the function invocation.

serverless invoke [local] --function functionName

Options

• --function or -f The name of the function in your service that you want to invoke. Required.
• --data or -d String data to be passed as an event to your function. By default data is read from standard input.
• --path or -p The path to a json file with input data to be passed to the invoked function. This path is relative to the root directory of the service.
• --type or -t The type of invocation. Either RequestResponse, Event or DryRun. Default is RequestResponse.
• --log or -l If set to true and invocation type is RequestResponse, it will output logging data of the invocation. Default is false.

Provided lifecycle events

• invoke:invoke

Invoke Local

Invokes a function locally for testing and logs the output. You can only invoke Node.js runtime locally at the moment. Keep in mind that we mock the context with simple mock data.

serverless invoke local --function functionName

Options

• --function or -f The name of the function in your service that you want to invoke locally. Required.
• --path or -p The path to a json file holding input data to be passed to the invoked function. This path is relative to the root directory of the service. The json file should have event and context properties to hold your mocked event and context data.
• --data or -d String data to be passed as an event to your function. Keep in mind that if you pass both --path and --data, the data included in the --path file will overwrite the data you passed with the --data flag.

Examples

Apache OpenWhisk

serverless invoke --function functionName

This example will invoke your deployed function on the configured platform endpoint. This will output the result of the invocation in your terminal.

Function invocation with data

serverless invoke --function functionName --data '{"name": "Bernie"}'

Function invocation with data from standard input

node dataGenerator.js | serverless invoke --function functionName

Function invocation with logging

serverless invoke --function functionName --log

Just like the first example, but will also outputs logging information about your invocation.

Function invocation with data passing

serverless invoke --function functionName --path lib/data.json

This example will pass the json data in the lib/data.json file (relative to the root of the service) while invoking the specified/deployed function.
