How do i update Google Cloud Function source?

Question

I've used this command to deploy a function from local source:

gcloud beta functions deploy helloWorld --trigger-http

Now, i have updated it's code. How do i deploy my changes?

When i'm using the same command, it returns status success with some details, but the deployed function remains intact (it uses the very first version of deployed code).

Answer 1

I am running into the same issue. I've deployed my original HTTP function, updated the source, and am now trying to redeploy.

This could perhaps be a bug in the gcloud CLI, but I was able to successfully redeploy from my local machine by leveraging the --source command line flag. Be sure to point this flag to the directory containing your index.js.

gcloud beta functions deploy helloWorld --source=/usr/local/path/to/source/dir --http-trigger

Where index.js would be located at /usr/local/path/to/source/dir/index.js. Further CLI documentation can be found at https://cloud.google.com/sdk/gcloud/reference/beta/functions/deploy.

Answer 2

Providing an updated answer for anyone that needs it. If you are wanting to just redeploy a function from source the following works assuming you are in the directory of the index.js file. And to clarify this is to redeploy to a gcp function that already exists, not a new one.

gcloud functions deploy <FUNCTION_NAME> --source=.
