Overview
The Overview tab is the primary connection hub for your MySQL database service. It displays everything needed to connect client applications, manage network access, configure private links, and control public accessibility.
How do I get the connection details for my database service?
Host
Hostname in the format <service-name>-<suffix>.<domain>. For HA services, Tessell keeps this DNS pointing to the current primary — applications should always use this hostname. Click the edit icon to rename the DNS (single-instance only); click copy to copy it.
Connect to
Indicates connections go to the Database.
Database
Database name for connection strings. Click copy to copy it.
Username
Username for connecting to the database. Click copy to copy.
Password
Set or reset the password here. Specify a new password and click Reset to change it. Click the eye icon to reveal the current password (encrypted by default).
Port
Database listener port. Default is 3306. Click copy to copy.
Service URL
Full connection URL. Each instance and database gets its own URL.
Note: Tessell supports DNS names without the suffix (format:
<servicename>.<domain>). Contact Tessell support to enable this.
Where do I find the SSL/TLS certificate for my database connection?
SSL/TLS is enabled at provisioning time — see Provisioning a MySQL DB service. Once enabled, the CA certificate section appears on this tab, letting you view, download, or copy the certificate.
How do I control which IP addresses can connect to my database?
The Allowed IP addresses section lists the client IPs from which connection requests are accepted (database port only).
Click the edit icon next to Allowed IP addresses.
In the Update Connectivity window, add or remove IP addresses.
Click + Add current client IP <address> to add your own IP automatically.
You can also add CIDR blocks to allow a range of addresses.
Click Update to apply.
Publicly accessible is disabled by default (Yes/No). To enable or disable it: click the edit icon next to Publicly accessible → toggle the value → click Update. Public access cannot be enabled if the VPC/VNet is configured for private access only.
How do I configure AWS PrivateLink for my database service?
AWS PrivateLink provides a private connection from your AWS VPC to the Tessell database service. Use this private link to connect to the primary instance; for HA services, it automatically routes to the acting primary during switchovers.
Steps to configure AWS PrivateLink
Click the edit icon next to AWS private link → the Private Link window opens.
Enter the ARN(s) of allowed AWS principals. Accepted formats:
AWS account:
arn:aws:iam::<account-id>:rootSpecific IAM user:
arn:aws:iam::<account-id>:user/<user-name>Specific IAM role:
arn:aws:iam::<account-id>:role/<role-name>
Click Create. The status changes to Updating.
Wait for the service endpoint to appear. Copy it.
In the AWS console, navigate to VPC → Endpoints → Create endpoint.
Choose Other endpoint services, paste the service endpoint noted above, and click Verify service.
Select the VPC and subnets, choose IPv4 for IP address type, and click Save.
Once the endpoint status is Available, note the DNS name from the VPC Details tab (the one without a region name).
Use this DNS name to connect to your database service.
How do I configure Azure Private Link for my database service?
Azure Private Link provides a private connection from your Azure VNet to the Tessell database service. Use this private link to connect to the primary instance; for HA services, it automatically routes to the acting primary during switchovers. A dedicated private link is required for DR/RR instances.
Steps to configure Azure Private Link
Click the edit icon next to Azure Private Link → the Private Link window opens.
Enter the allowed Azure subscription ID and press Enter.
Click Create. Wait for the service endpoint to appear and copy it.
In the Azure portal, navigate to Private endpoints → + Create.
On the Basics tab: choose a resource group, enter a name, and select a region.
On the Resource tab: select Connect to an Azure resource by resource ID or alias, and specify the service endpoint from the Tessell portal.
On the Virtual Network tab: select your virtual network and subnet.
Leave DNS as default → optionally add tags → click Create.
After Tessell approves the connection request, the connection state changes to Approved.
Note the private IP of the private endpoint and use it as the hostname in your service URL.
What are Tags on the Overview tab?
The Tags section displays key-value pair tags assigned to the database service. A unique tag is assigned at provisioning time.
What does the Refresh History section show?
The Refresh History section is displayed only for cloned services. It shows the last refreshed date and time for the clone.
