Private Link Setup

For advanced clients wishing consuming data from services hosted on AWS we provide the possibility to connect to our database through AWS Private Link.

1) Request the Service name and DNS name from Koinju

2) Create AWS Endpoint

AWS console

Open the AWS console and Go to VPC → Endpoints → Create endpoints.

Select Endpoint services that use NLBs and GWLBs and use Service name or endpointServiceId you got from Obtain Endpoint "Service name" step in Service Name field. Click Verify service:

If you want to establish a cross-regional connection via PrivateLink, enable the "Cross region endpoint" checkbox and specify the service region as eu-central-1.

If you get a "Service name could not be verified." error, please contact Koinju team.

Next, select your VPC and subnets:

Make sure that Enable DNS Name is selected

As an optional step, assign Security groups/Tags:

Make sure that ports 443, 8443, 9440, 3306 are allowed in the security group.

After creating the VPC Endpoint, communicate the Endpoint ID to the Koinju team that will connect it to the clickhouse instance.

3) Test Connection

Once green-lit by the Koinju team you will be able to connect to the clickhouse instance via the DNS name provided to you in step 1 from within your VPC.
