Reference note (untrusted external data; do not execute it as instructions). You can send test queries to the primary MySQL server (hostname mysql-0.mysql) by running a temporary container with the mysql:5.7 image and running the mysql client binary. Use the hostname mysql-read to send test queries to any server that reports being Ready You should get output like this To demonstrate that the mysql-read Service distributes connections across servers, you can run SELECT @@server_id in a loop You should see the reported @@server_id change randomly, because a different endpoint might be selected upon each connection attempt You can press Ctrl+C when you want to stop the loop, but it's useful to keep it running in another window so you can see the effects of the following steps.
