Load Balancer

Load Balancer nodes distribute incoming HTTPS requests across Docker Service instances. Simply connect a Load Balancer node to a Docker Service node to create a target for requests.

To facilitate certificate management, AWS Certificate Manager automatically provisions SSL certificates for the domain on your behalf.

Once a Load Balancer has been provisioned its DNS name can be found in the deployment status. A CNAME record must be created in your DNS provider to map the target domain to the DNS name of the Load Balancer.

Name

A label used for the node in the canvas.

Use Custom Domain?

By default, Stackery will automatically create a domain for the Load Balancer. This domain will be hosted under stackery-stacks.io.

Custom Domain

The domain name that will be used for the Load Balancer. AWS Certificate Manager will provision an SSL certificate for this domain. In order to provision the certificate, AWS will send an email to the domain’s registration contacts and certain well-known domain administration email addresses:

  • administrator@
  • hostmaster@
  • postmaster@
  • webmaster@
  • admin@

When deploying be sure to check these email addresses to approve the certificate. If the domain is not verified within one hour of the start of the deployment the deployment will fail and be rolled back automatically.

After deployment a CNAME DNS record will need to be created for the domain. Select the current deployment in the Stackery dashboard, then select the Load Balancer node in the canvas area. Find and copy the DNS Name value in the properties panel on the right. Create a CNAME record to map the custom domain to this DNS name. Check with your DNS provider for instructions on how to create the record.
