+# Cloud SQL Database Example
+
+This example shows how create Cloud SQL databases for for MySQL and PostgreSQL using the Terraform module.
+
+**Figure 1.** *diagram of Google Cloud resources*
+
+![architecture diagram](./diagram.png)
+
+## Run Terraform
+
+```
+terraform init
+terraform plan
+terraform apply
+```
+
+## Test connection to database
+
+Install the Cloud SQL Proxy: https://cloud.google.com/sql/docs/mysql/sql-proxy#install
+
+Run the Cloud SQL proxy for MySQL instance:
+
+```
+GOOGLE_PROJECT=$(gcloud config get-value project)
+
+MYSQL_DB_NAME=$(terraform output -module mysql-db -json | jq -r '.instance_name.value')
+MYSQL_CONN_NAME="${GOOGLE_PROJECT}:us-central1:${MYSQL_DB_NAME}"
+
+PGSQL_DB_NAME=$(terraform output -module postgresql-db -json | jq -r '.instance_name.value')
+PGSQL_CONN_NAME="${GOOGLE_PROJECT}:us-central1:${PGSQL_DB_NAME}"
+
+./cloud_sql_proxy -instances=${MYSQL_CONN_NAME}=tcp:3306,${PGSQL_CONN_NAME}=tcp:5432
+```
+
+Start Cloud SQL Proxy for Postgres instance:
+
+```
+GOOGLE_PROJECT=$(gcloud config get-value project)
+
+PGSQL_DB_NAME=$(terraform output -module postgresql-db -json | jq -r '.instance_name.value')
+PGSQL_CONN_NAME="${GOOGLE_PROJECT}:us-central1:${PGSQL_DB_NAME}"
+
+./cloud_sql_proxy -instances=${PGSQL_CONN_NAME}=tcp:3306
+```
+
+Get the generated password:
+
+```
+echo MYSQL_PASSWORD=$(terraform output -module mysql-db -json | jq -r '.generated_user_password.value') 
+echo PGSQL_PASSWORD=$(terraform output -module postgresql-db -json | jq -r '.generated_user_password.value') 
+```
+
+Test the MySQL connection:
+
+```
+mysql -udefault -p --host 127.0.0.1 default
+```
+
+> When prompted, enter the value of MYSQL_PASSWORD
+
+Test the PostgreSQL connection:
+
+```
+psql -h 127.0.0.1 --user default
+```
+
+> When prompted, enter the value of PGSQL_PASSWORD
