Setup Redis on AWS CodeBuild

Question

I am setting a CI/CD using AWS CodeBuild. But I got a problem that can't start the redis system.

[Container] 2023/06/27 09:16:34 Running command sudo systemctl start redis6
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

[Container] 2023/06/27 09:16:34 Command did not exit successfully sudo systemctl start redis6 exit status 1
[Container] 2023/06/27 09:16:34 Phase complete: INSTALL State: FAILED
[Container] 2023/06/27 09:16:34 Phase context status code: COMMAND_EXECUTION_ERROR Message: Error while executing command: sudo systemctl start redis6. Reason: exit status
