Cloud Container Builder, ZIP does not support timestamps before 1980 - google-app-engine

Question

I'm trying the following tutorial.
Automatic serverless deployments with Cloud Source Repositories and Container Builder
But I got the error below.
$ gcloud container builds submit --config deploy.yaml .
BUILD
Already have image (with digest): gcr.io/cloud-builders/gcloud
ERROR: (gcloud.beta.functions.deploy) Error creating a ZIP archive with the source code for directory .: ZIP does not support timestamps before 1980
ERROR
ERROR: build step 0 "gcr.io/cloud-builders/gcloud" failed: exit status 1
I'm now trying to solve it. Do you have any idea? My gcloud is the latest version.
$ gcloud -v
Google Cloud SDK 193.0.0
app-engine-go
app-engine-python 1.9.67
beta 2017.09.15
bq 2.0.30
core 2018.03.09
gsutil 4.28
Sample google cloud function code on the tutorial.
#index.js
exports.f = function(req, res) {
res.send("hello, gcf!");
};
#deploy.yaml
steps:
- name: gcr.io/cloud-builders/gcloud
args:
- beta
- functions
- deploy
- --trigger-http
- --source=.
- --entry-point=f
- hello-gcf # Function name
#deploying without Cloud Container Builder is fine.
gcloud beta functions deploy --trigger-http --source=. --entry-point=f hello-gcf

Answer 1

Container Builder tars your source folder. Maybe something in your . directory has corrupted dates? That's why moving it to the source folder fixes it.

Answer 2

While I don't know the reason, I found a workaround.
(1) make src directory and move index.js into it.
├── deploy.yaml
└── src
└── index.js
(2) deploy via Cloud Container Builder.
$ gcloud container builds submit --config deploy.yaml ./src

I ran into the same issue now. I could not solve it but at least I found out where it comes from.
When you locally submit your build there is a tar created and uploaded to a bucket. In this tar the folders are created at 01.01.1970:
16777221 8683238 drwxr-xr-x 8 user staff 0 256 "Jan 1 01:00:00 1970" "Jan 1 01:00:00 1970" "May 15 12:42:04 2019" "Jan 1 01:00:00 1970" 4096 0 0 test
This issue only occurs locally. If you have a github build trigger it works

I recently came across the same issue using Cloud Build (the successor to Container Builder).
What helped was adding a step to list all the files/folders in the Cloud Build environment (default directory is /workspace) to identify the problematic file/folder. You can do this by overriding the gcloud container's entrypoint to execute the ls command.
steps
- name: gcr.io/cloud-builders/gcloud
entrypoint: "ls"
args: ["-la", "/workspace"]
