Uji Koneksi

Lihat panduan set environment variables.

Untuk tes koneksi SQL di saleor amannya kita tidak setel DATABASE_URL spt dijelaskan di sbb:

Note (5. Create a PostgreSQL user)
You need to create the user to use within your project. 
Username and password are extracted from the DATABASE_URL environmental variable. 
If absent they both default to saleor.

Note (6. Create a PostgreSQL database)
Database name is extracted from the DATABASE_URL environment variable. 
If absent it defaults to saleor.

Console

Buat user saleor dengan password saleor di PENGGUNA dan database saleor di BASIS DATA

CloudShell

https://console.cloud.google.com/cloudshell/environment/view
Matikan dahulu SSL dengan cara Izinkan koneksi yang tidak aman di KONEKSI

gcloud sql connect cloud-sql-postgres-instance --user=saleor

Output

Whitelisting your IP for incoming connection for 5 minutes...done.
Connecting to database with SQL user [saleor].Password for user saleor:

Masukan password saleor tekan Enter. Outputnya spt berikut:

psql (9.6.10)
SSL connection (protocol: TLSv1.2, cipher: ECDHE-RSA-AES128-GCM-SHA256, bits: 128, compression: off)
Type "help" for help.

Tes Proxy

https://codelabs.developers.google.com/codelabs/cloud-postgresql-gke-memegen/#5

gcloud iam service-accounts create proxy-user --display-name "proxy-user"
gcloud iam service-accounts list

gcloud projects add-iam-policy-binding marketstore \ 
--member serviceAccount:[email protected] \
--role roles/cloudsql.client

gcloud iam service-accounts keys create key.json \ 
--iam-account [email protected]

Deploy Proxy

Follow a guide to setup "generic" Kubernetes cluster and remember to set environment variables when creating your workload based on the uploaded image.

kubectl create secret generic cloudsql-instance-credentials \
--from-file=credentials.json=key.json

kubectl create secret generic cloudsql-db-credentials \
    --from-literal=secretKey=[SECRET_KEY] \
    --from-literal=allowedHosts=shop.chetabahana.com \
    --from-literal=currency=Rp
