Instalasi di GAE - MappingSystem/Tutorial-Buka-Toko GitHub Wiki

Sesi ini kita akan kupas tentang cara mempersiapkan Instalasi Saleor di GAE

Table of Contents

Deploy

Setelah kita selesai membuat Aplikasi di PC maka kita bisa pasang via Source Code dan juga via Build Image baik secara Manual via Gcloud maupun secara Otomatis via Cloud Build.

Via Source Code

Pemasangan via Source Code di GAE akan mengikuti kaidah Django dimana berdasarkan tutorial app.yaml bisa pakai gunicorn

  • Masukkan code entrypoint: gunicorn -b :$PORT saleor.wsgi kedalam file app.yaml
  • Tambahkan baris dengan code gunicorn==19.7.1 kedalam file requirements.txt
  • Saleor butuh memory lebih dari 128MB. Minimum instance_class: F2/B2
app.yaml 
env: standard
service: product
runtime: python37
entrypoint: gunicorn -b :$PORT saleor.wsgi

instance_class: F2
automatic_scaling:
  max_instances: 1

env_variables:
  SECRET_KEY: [DJANGO_SECRET_KEY]
  ALLOWED_HOSTS: product-dot-chetabahana.appspot.com,www.chetabahana.com
  DATABASE_URL: postgresql://saleor:[email protected]/saleor
  DEFAULT_CURRENCY: Rp
  DEFAULT_COUNTRY: INDONESIA
  CREATE_IMAGES_ON_DEMAND: False

handlers:
- url: /static
  static_dir: static/

- url: /.*
  script: auto
$ gcloud app deploy --version=v1-4

Via Build Image

Setelan app.yaml lihat: 

docker run -d gcr.io/chetabahana/saleor
CONTAINER_ID=$(docker ps -alq)
docker cp $CONTAINER_ID:/app .
docker stop $CONTAINER_ID
cd app
rm -rf Pipfile
rm -rf Pipfile.lock
cat 'gunicorn==19.7.1' > requirements.txt
gcloud app deploy --version=v1-4

Database

Cloud SQL

Untuk jalankan Cloud SQL perlu Aktifkan Billing dan SQL Admin API 
$ gcloud sql connect instance-postgres --user=saleor

virtualenv env
source env/bin/activate
pip install -r requirements.txt
