If you leave the
CognitoCallbackDomain parameter blank during installation and want to use your own domain later, you will need to route traffic to the LoadBalancer and change the Cognito App client settings.A) Re-route your DNS
- Example instruction to route traffic using Route 53: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/routing-to-elb-load-balancer.html

Parameter
Value
ARNCertificate
SSL certificate from point 3 above. More information on certificates is available here: https://docs.aws.amazon.com/acm/latest/userguide/acm-overview.html
Example:
arn:aws:acm:us-east-1:123456789012:certificate/1156aa0c-daa3-4cb1-af6d-6f16202ebf2cCognitoCallbackDomain
Add the domain(s) where you will access BlockScout and append “/oauth2/idpresponse" to the end. If you do not have a domain, leave this field blank. It will be populated with the LoadBalancerDNS created at the end of the process.
Example:
https://your.domain/oauth2/idpresponseCognitoUserEmail
Enter any valid email. You will receive a temporary password here after deployment.
Example:
[email protected]DBPassword
Add a secure password here for database access. Must contain only letters and numbers, and be 8 characters or more. Record this password for later access.
EthereumJsonRPCHttpURL
This is the node url used to fetch blocks, transactions, receipts & tokens. See the instructions on setting up a node on AWS for more information. If setup through AWS, you can find the address in EC2 Dashboard -> Instances -> click to corresponding archive node instance.
You will retrieve the ip address and add the port number afterwards. The port for Parity is 8545.
Example:
http://node.ip.address:8545EthereumJsonRPCTraceURL
Input the same value as above. This is used to fetch internal transactions and block traces.
Example:
http://node.ip.address:8545EthereumJsonRPCWsURL
The Network RPC endpoint in websocket mode. The default parity port is 8546.
Example:
ws://localhost:8546GraphiQLTransaction
Any transaction from the chain can be used. This hash provides a sample query in the GraphIQL Playground and always begins with “0x…”
Example:
0x9415741aa80cacb3e2a9f48506010a3f31fddc7e7a00421381b4e4679d5eba20IngressIPRangeLB
IP address range for access to your LoadBalancer instance. Recommend using
0.0.0.0/0 for access from all IPs, or specify your local IP with your.ip/32. You can find your ip here: https://support.google.com/websearch/answer/1696588InstanceKey
From step 2 above. The instance key name is located at EC2 Dashboard -> Network & Security -> Key Pairs. It should be available as a dropdown in the template.
SecretKeybase
Secret key for production assets protection in base64. You can generate this on the command line of your local machine using the following command: "openssl rand -base64 16"
