Deploying three MySQL instances with the help of OCI CLI (for more details on how to proceed with OCI CLI creation for MySQL instance, review )
Each of the three database has been deployed in a different Availability Domain; Each of these three databases have the same compartmentID and subnetID
Json file for deploying 1st DB database:
root@deploymentmachine:/home/tests/mydb# more mydb1.json
{

Deploy 1st DB with command:
root@deploymentmachine:/home/tests/mydb# oci mysql db-system create --from-json file://mydb1.json

}
Deploy 2nd DB with command:
root@deploymentmachine:/home/tests/mydb# oci mysql db-system create --from-json file://mydb2.json
Json file for deploying 3rd DB instance:
root@deploymentmachine:/home/tests/mydb# more mydb3.json

Deploy 3rd DB with command:
root@deploymentmachine:/home/tests/mydb# oci mysql db-system create --from-json file://mydb3.json
If no output errors after running command "oci mysql db-system create", check the Oracle Cloud UI:
Do not forget the Ingress rules for MySQL services:
The deployed instances have following private IPs:
