OpenWhisk - Deploy Function
The sls deploy function
command deploys an individual function. This command simply compiles a deployment package with a single function handler. This is a much faster way of deploying changes in code.
serverless deploy function -f functionName
Note: Because this command is only deploying the function code, function properties such as environment variables and events will not be deployed.
