Deploy python3 appengine standard env using bazel and cloud deploy using non containerized artifact?

[Akkul Sahariya]

Referring to this[

How to deploy to appengine flexible using bazel and google cloud deploy using non containerized artifact?]

I would appreciate if somebody could give me a definitive guide to using bazel to deploy a non containerized python3 standard env steps.

See Deploying artifacts on appengine. I would like to understand how to configure the cloudbuild.yaml to use bazel and run python3 server.

Right now I have changed my project structure to:

.
├── app.yaml
└── package
    ├── app
    │   ├── BUILD
    │   ├── entry.py
    │   ├── forms.py
    │   ├── __init__.py
    │   ├── jinja_custom_filter.py
    │   ├── models.py
    │   ├── __pycache__
    │   ├── static
    │   ├── templates
    │   ├── utils.py
    │   └── views.py
    ├── app.db
    ├── app.yaml
    ├── BUILD
    ├── cloudbuild.yaml
    ├── config.py
    ├── LICENSE
    ├── main.py
    ├── manage.py
    ├── requirements.txt
    └── WORKSPACE
so this structure is different from what I posted on SO.

Here is my main.py

#!flask/bin/python
from app.entry import app
import os
port = int(os.environ.get('PORT', 8081))
print('hello world!', port)

app.run(host='0.0.0.0', debug=True)

Now the error that i get is:

When deploying App GAE Standard, it auto creates the Cloud Build image but cannot be altered or use Bazel. If you intend to use Bazel command in Cloud Build you can follow the instructions here.

Based on the information you've provided, this seems to be running in GAE Flex but the title is GAE Standard. Can you confirm which one you are referring to?

[Akkul Sahariya]

Hi Aref,

So if I understood this correct:

IN CLOUDBUILD.YAML:
steps:
# Build the Docker image and load it into the Docker daemon.
- name: 'gcr.io/cloud-builders/docker'
  args: ['build', '--tag=gcr.io/$PROJECT_ID/deploy:latest', '.']
  # The loaded image name is the BUILD target's name, prefixed with bazel/.
- name: 'gcr.io/cloud-builders/bazel'
  args: ['run', 'gcr.io/$PROJECT_ID/deploy:latest']
# Re-tag the image to something in your project's gcr.io repository.
- name: 'gcr.io/cloud-builders/docker'
  args: ['tag', 'gcr.io/$PROJECT_ID/deploy:latest', 'gcr.io/$PROJECT_ID/server']
# Push the image.
images: ['gcr.io/$PROJECT_ID/server']


In WORKSPACE:
load(
    "@io_bazel_rules_docker//python:image.bzl",
    _py_image_repos = "repositories",
)

_py_image_repos()


IN BUILD FILES:
  load("@io_bazel_rules_docker//python:image.bzl", "py3_image")

  REPLACE py_binary with py3_image(
  name = "py_image",
  srcs = ["py_image.py"],
  deps = [":py_image_library"],
  main = "py_image.py",
  # "layers" is just like "deps", but it also moves the dependencies each into
  # their own layer, which can dramatically improve developer cycle time.  For
  # example here, the grpcio layer is ~40MB, but the rest of the app is only
  # ~400KB.  By partitioning things this way, the large grpcio layer remains
  # unchanging and we can reduce the amount of image data we repush by ~99%!
  layers = [
    requirement("grpcio"),
    "//examples/hellogrpc/proto:py",
  ],
  )

And then

sudo gcloud builds submit --config package/cloudbuild.yaml ./package/

 sudo gcloud app deploy app.yaml Enter code here...

Is this the correct way to use bazel and deploy to gae standard?

Thanks.

[Akkul Sahariya]

Another question is, is using bazel using standard gae a best practice or would you suggest otherwise?

You can follow the instructions provided here to help you with building Java App Engine application or Python App Engine application with Bazel. In addition, for best practices and deploying rules, I'd suggest review this page.

If you need additional assistance with technical question, it is recommended to post your detailed questions to Stackoverflow using the supported Cloud tags, as Google Groups is mainly reserved for general product discussions.

Hello Akkul, 

Right reply to your question depends on details such as correct paths and similar. If you followed the provided example faithfully, you should succeed. 

This discussion group is oriented more towards general opinions, trends, and issues of general nature touching App Engine and Cloud SQL. For coding and programming architecture, as well as using Bazel to deploy a non containerized python3 standard env, you may be better served in dedicated forums such as stackoverflow, where experienced programmers are within reach and ready to help.
