batcave-tf-mssql

This is a Terraform module for a Microsoft SQL Server (Standard Edition) for AWS RDS

• Note that credentials are stored in AWS Secrets Manger

Debugging Tips

Once the mssql RDS is up and running, you may want to test connectivity from the cluster. To do this:

1. Start an interactive diagnostic pod with mssql tooling (note your shell will hang, so you'll likely need multiple terminals open):

  kubectl run mssql-diag --image=mcr.microsoft.com/mssql-tools --restart=Never -n default --overrides='{"spec":{"tolerations":[{"effect": "NoSchedule","key": "CriticalAddonsOnly","operator": "Exists" }]}}' -i --tty

2. In a separate terminal, shell into the mssql-diag pod and run the following command to test connectivity:

sqlcmd -U regscale -P <password> -S <server-url> -Q "SELECT * FROM SYSOBJECTS WHERE xtype='U';"

You should see output showing the tables in the mssql database.

3. Delete the mssql-diag pod when finished
