Cloud function deployment time

Question

I am deploying a function to cloud function, but it takes substantial time to deploy. How can I optimize my deployment?

I have tried deployed with and without go.mod. I have also tried include vendor (go mod vendor).

gcloud functions deploy FuncX --entry-point FuncX --runtime go111 --trigger-http

I've observed similar behavior. This seems to happen when your go.mod file includes large packages that need to be fetched during deployment. To streamline deployments make sure, you can vendor your dependencies (go mod tidy, go mod vendor).

Note that if you your deployed files include a go.mod file, the vendor directory will be ignored. If you deploy your functions using the gcloud CLI, create a .gcloudignore file in your project's directory and add go.mod and go.sum to that file.

For example:

.gcloudignore

.gcloudignore
.git
.gitignore
go.mod
go.sum

In my case it reduced deployment time up to 4 times.
