Getting started with Managed Service for PostgreSQL

To use the service, create a cluster and connect to a DBMS:

All you need to create a database cluster is a folder in Yandex.Cloud that you are allowed to access. If you already have a folder in Yandex.Cloud, open the page of that folder in the management console. If there is no folder yet, create one:
1. On the management console home page, click Create folder.
2. Enter the folder name.
  
  The name may contain lowercase Latin letters, numbers, and hyphens. The first character must be a letter. The last character can't be a hyphen. The length of the name must be from 3 to 63 characters.
3. Click Create folder.
You can connect to DB clusters from both inside and outside of the Cloud:
1. To connect to a DB cluster from inside the Cloud, create a VM in the same network as the DB cluster (based on Linux or [Windows](../compute/quickstart/quick-create-windows md))
2. To enable connection to a cluster over the internet, request external IP addresses for hosts when creating the cluster.
In the management console, select the folder where you want to create a DB cluster.
Select Managed Service for PostgreSQL.
Click Create cluster and select the necessary DBMS.
Set the cluster parameters and click Create cluster. This process is described in detail in Creating PostgreSQL clusters.
When the cluster is ready, its status in the Managed Service for PostgreSQL dashboard will change to RUNNING.
To connect to the DB server, an SSL certificate is required. You can prepare all the necessary authentication data as follows:
```
$ mkdir ~/.postgresql
$ wget "https://storage.yandexcloud.net/cloud-certs/CA.pem" -O ~/.postgresql/CA.pem
```
You can connect to the database using the psql command (for more information, see Connecting to a database in a PostgreSQL cluster):
```
$ psql "host=<host address> \
      port=6432 \
      sslmode=verify-full \
      dbname=<DB name> \
      user=<DB username>"
```
