1C Cluster Domains

warning

When managing a domain, 1C server clusters are restarted to apply web server and web publishing settings for databases. This makes the databases unavailable and terminates all sessions.

We recommend scheduling maintenance during periods of low cluster load and using session blocking for associated information databases.

You can link a domain to a 1C cluster to access all infobases in the cluster using a custom link of the form https://<example.ru>/<infobase_name>.

For each database, only active domains linked to a server cluster will be displayed. You can view all domains, certificate expiration dates, and their statuses on the cluster page.

You can connect to infobases via a domain only if web publishing is enabled. You can view web publishing settings in the Control panel: in the top menu, click Products → 1C Managed Cloud → Infobases section → infobase page → Connection tab.

You can also transfer the domain to another cluster or delete the domain.

Bind a domain to a cluster

Only Latin-character domains can be bound to a 1C server cluster.

In the Control panel, in the top menu, click Products → 1C Managed Cloud.
Go to the 1C server clusters section
Open the cluster page → Connection tab.
Select Thin client / WEB.
In the Custom domains block, click Link.
Select a domain zone from the list or add a domain zone from another DNS hosting provider.
If the domain zone is on another DNS hosting provider:

7.1. In the DNS hosting of your domain, create a CNAME record with the value *.selcloud.ru.

7.2. Set the TTL value to 300 seconds or less.

7.3. Wait 15–20 minutes for the changes to take effect.

7.4. In the Control panel, in the Cluster address field, enter the domain from step 7.1.
If the domain is delegated in Selectel:

8.1. Select a zone from the list. The zone must be delegated. To delegate a zone to Selectel, see the Delegate a zone (domain) instructions.

8.2. Enter the subdomain name. You can use a third-level domain or higher.
If you do not have a Let’s Encrypt certificate for the domain, issue one. To do this, in the SSL/TLS certificate block, select Issue Let’s Encrypt certificate.
If you have your own certificate, upload it:

10.1. In the SSL/TLS certificate block, select Upload your own certificate.

10.2. Enter the certificate data or upload the certificate file in .pem or .crt format.

10.3Enter the private key data or upload the key file in .key format.
Click Link domain.

Transfer a domain to another cluster

A domain can be transferred to another 1C server cluster in the same project and pool. Along with the domain, the SSL/TLS certificate is also transferred to the other cluster.

Links from the domain to the databases of the new 1C server cluster will be unavailable. To keep access via existing links, move the databases to the target 1C server cluster in advance.

In the Control panel, in the top menu, click Products → 1C Managed Cloud.
Go to the 1C server clusters section
Open the cluster page → Connection tab.
Select Thin client / WEB.
In the Custom domains block, in the domain row, click .
Click Transfer to another cluster.
Select the cluster to which you want to transfer the domain from the list.
Click Transfer.
Wait for the domain to be moved to the other cluster. CNAME record verification may take up to five minutes.
The cluster will reboot.

Delete a domain

When a cluster is deleted, all user domains bound to it will also be deleted.

In the Control panel, in the top menu, click Products → 1C Managed Cloud.
Go to the 1C server clusters section
Open the cluster page → Connection tab.
Select Thin client / WEB.
In the Custom domains block, in the domain row, click .
Click Delete domain.
Enter the domain name to confirm.
Click Delete.
