gcloud Overwrite .gitignore in .gcloudignore

.gcloudignore is used to exclude certain files for deployment.

By default, .gcloudignore include the rules of .gitignore as well.

# This file specifies files that are *not* uploaded to Google Cloud Platform
# using gcloud. It follows the same syntax as .gitignore, with the addition of
# "#!include" directives (which insert the entries of the given .gitignore-style
# file at that point).
#
# For more information, run:
#   $ gcloud topic gcloudignore
#
.gcloudignore
# If you would like to upload your .git directory, .gitignore file or files
# from your .gitignore file, remove the corresponding line
# below:
.git
.gitignore

node_modules
#!include:.gitignore

I edited .gitignore to prevent secret.py from being added into git.

# custom
secret.py

But I need the file to be deployed via gcloud. Edit .gcloudignore in the following manner.

# This file specifies files that are *not* uploaded to Google Cloud Platform
# using gcloud. It follows the same syntax as .gitignore, with the addition of
# "#!include" directives (which insert the entries of the given .gitignore-style
# file at that point).
#
# For more information, run:
#   $ gcloud topic gcloudignore
#
.gcloudignore
# If you would like to upload your .git directory, .gitignore file or files
# from your .gitignore file, remove the corresponding line
# below:
.git
.gitignore

node_modules
#!include:.gitignore

# custom
!secret.py
