ANSLUTA FRÅN APP ENGINE (FLEX OCH STANDARD) TILL MOLNET SQL MED TCP OCH UNIX DOMAIN SOCKETS 2020
1.Skapa ett nytt projekt
gcloud projects create con-ae-to-sql
gcloud config set project con-ae-to-sql
gcloud projects describe con-ae-to-sql
2. Aktivera fakturering för ditt projekt:https://cloud.google .com/billing/docs/how-to/modify-project
3. Kör följande gcloud-kommando för att aktivera App Engine och skapa tillhörande programresurser
gcloud app create -region europe-west2
gcloud app describe
#Remember the location of you App Engine aplication, because we will create all our resources on the same region
4. Ställ in metadata för beräkning av projektinformation:
gcloud compute project-info describe --project con-ae-to-sql
#Enable the Api, and you can check that default-region,google-compute-default-zone are not set. Set the metadata.
gcloud compute project-info add-metadata --metadata google-compute-default-region=europe-west2,google-compute-default-zone=europe-west2-b
5.Aktivera Service Networking API:
gcloud services list --available
gcloud services enable servicenetworking.googleapis.com
6.Skapa 2 cloud sql-instanser, (en med intern ip och en med offentlig ip)- https://cloud.google.com/sql/docs/mysql/create-instance :
6.a Cloud SQL-instans med extern ip:
#Create the sql instance in the same region as App Engine Application
gcloud --project=con-ae-to-sql beta sql instances create database-external --region=europe-west2
#Set the password for the "[email protected]%" MySQL user:
gcloud sql users set-password root --host=% --instance database-external --password root
#Create a user
gcloud sql users create user_name --host=% --instance=database-external --password=user_password
#Create a database
gcloud sql databases create user_database --instance=database-external
gcloud sql databases list --instance=database-external
6.b Cloud SQL-instans med intern ip:
i.#Create a private connection to Google so that the VM instances in the default VPC network can use private services access to reach Google services that support it.
gcloud compute addresses create google-managed-services-my-network --global --purpose=VPC_PEERING --prefix-length=16 --description="peering range for Google" --network=default --project=con-ae-to-sql
gcloud services vpc-peerings connect --service=servicenetworking.googleapis.com --ranges=google-managed-services-my-network --network=default --project=con-ae-to-sql
#Check whether the operation was successful.
gcloud services vpc-peerings operations describe --name=operations/pssn.dacc3510-ebc6-40bd-a07b-8c79c1f4fa9a
#Listing private connections
gcloud services vpc-peerings list --network=default --project=con-ae-to-sql
ii.Create the instance:
gcloud --project=con-ae-to-sql beta sql instances create database-ipinternal --network=default --no-assign-ip --region=europe-west2
#Set the password for the "[email protected]%" MySQL user:
gcloud sql users set-password root --host=% --instance database-ipinternal --password root
#Create a user
gcloud sql users create user_name --host=% --instance=database-ipinternal --password=user_password
#Create a database
gcloud sql databases create user_database --instance=database-ipinternal
gcloud sql databases list --instance=database-ipinternal
gcloud sql instances list
gcloud sql instances describe database-external
gcloud sql instances describe database-ipinternal
#Remember the instances connectionName
OK, så vi har två mysql-instanser, vi kommer att ansluta från App Engine Standard till databas-ipinternal med serverlös åtkomst och TCP, från App Engine Standard till databasextern med unix-domänsocket, från App Engine Flex till databas-ipinternal med TCP, och från App Engine Flex till databasextern med unix-domänsocket.
7.Aktivera Cloud SQL Admin API
gcloud services list --available
gcloud services enable sqladmin.googleapis.com
8. För närvarande stöder inte App Engine-standardmiljöer anslutning till Cloud SQL-instansen med TCP. Din kod ska inte försöka komma åt instansen med en IP-adress (som 127.0.0.1 eller 172.17.0.1) om du inte har konfigurerat Serverless VPC Access. Så låt oss konfigurera Serverless VPC Access.
8.a Se till att Serverless VPC Access API är aktiverat för ditt projekt:
gcloud services enable vpcaccess.googleapis.com
8.b Skapa en anslutning:
gcloud compute networks vpc-access connectors create serverless-connector --network default --region europe-west2 --range 10.10.0.0/28
#Verify that your connector is in the READY state before using it
gcloud compute networks vpc-access connectors describe serverless-connector --region europe-west2
9.App Engine använder ett tjänstkonto för att auktorisera dina anslutningar till Cloud SQL. Detta tjänstkonto måste ha rätt IAM-behörighet för att kunna ansluta. Unless otherwise configured, the default service account is in the format [email protected] nt.com. Se till att tjänstkontot för din tjänst har följande IAM-roller:Cloud SQL Client, och för att ansluta från App Engine Standard till Cloud SQL på intern ip behöver vi också rollen Compute Network User.
gcloud iam service-accounts list
gcloud projects add-iam-policy-binding con-ae-to-sql --member serviceAccount:[email protected] --role roles/cloudsql.client
gcloud projects add-iam-policy-binding con-ae-to-sql --member serviceAccount:[email protected] --role roles/compute.networkUser
Nu när jag har konfigurerat inställningen
1. Anslut från App Engine Standard till Cloud SQL med Tcp och unix domanin-socket

app = Flask(__name__)
@app.route('/')
def hello():
engine_tcp = create_engine('mysql+pymysql://user_name:[email protected]:3306')
existing_databases_tcp = engine_tcp.execute("SHOW DATABASES;")
con_tcp = "Connecting from APP Engine Standard to Cloud SQL using TCP: databases => " + str([d[0] for d in existing_databases_tcp]).strip('[]') + "\n"
engine_unix_socket = create_engine('mysql+pymysql://user_name:[email protected]/user_database?unix_socket=/cloudsql/con-ae-to-sql:europe-west2:database-external')
existing_databases_unix_socket = engine_unix_socket.execute("SHOW DATABASES;")
con_unix_socket = "Connecting from APP Engine Standard to Cloud SQL using Unix Sockets: tables in sys database: => " + str([d[0] for d in existing_databases_unix_socket]).strip('[]') + "\n"
return con_tcp + con_unix_socket
gcloud app deploy -q
