How to deploy multiple functions using serverless cli?

Question

From the doc, I can deploy a function like this

serverless deploy function -f functionName

https://www.serverless.com/framework/docs/providers/aws/cli-reference/deploy-function/

Can I deploy multiple functions with a command like this?

  serverless deploy function -f functionName1, functionName2

If can't, what should I do deploy multiple functions at once?

Thanks

The serverless-cli does not support deploying multiple functions in one go. I'm attached a bash function that you can add to your bashrc so it's always loaded automatically for you (instead of copy-ing and past-ing it when opening a new terminal)

serverless-deploy-function() {
    # Validate at least one parameter is passed
    [ "$#" -ne 1 ] && echo "USAGE $0 <PARAMETER>" && return 2

    # create a list of the first parameter (split by ,)
    declare -a FUNCTIONS_TO_DEPLOY=($(echo $1 | tr "," " "))

    # remove the first parameter from $@
    shift;
    # loop on the list of functions to deploy
    for x in $FUNCTIONS_TO_DEPLOY
    do
        echo Running \"serverless deploy function -f $x $@\"
        # Pass one function at a time and keep the rest of the arguments the same
        serverless deploy function -f $x $@
    done
}

To use it, you'll need to do something like this:

$ serverless-deploy-function function1,function2

Keep in mind, this should also support extra parameters given that you add them after the function(s) you want to deploy:

$ serverless-deploy-function function1,function2 --stage dev --region us-east-1

or for one function, as follows:

$ serverless-deploy-function function1 --stage dev --region us-east-1
