reviewing the user data changes.
the solution suggested by @eliezerchavez works
the script that you provided @acantril for some reason do not work as expected
hi, it does work fine, i've just tested it. @herrmadbeef
I suspect you made a mistake and changing to this new script fixed it because you did another run through.
I tested several Times !
I used the script provided b @eliezerchavez
when I used yours I always got the following error
The scripts do the same thing ... it's just a more efficient way of doing it @herrmadbeef
But to repeat again, i've just tested it with my script and confirmed it works ok.
There are also no other reports of any issues.
@acantril
same Launch template
the only difference is this
Failed
#!/bin/bash -xe
Working
#!/bin/bash
I can show you the error and the change if you want
OR
I can create a branch with just with the change
Ok you keep saying "failed"
I've tested it, it's working fine
i've asked a few students to test, it's working fine.
Trust me, you had a typo of some kind or some other issue
the -xe does nothing which could cause this to fail.
if you want to see what the issue is
try with my script
connect to the instance
then look at the cloud-init logs and see where the failure is.
this will tell you what the issue is.
Failed to connect to database either means the database server is not running
it isn't installed
or the password you chose isn't the one i suggested and is causing issues.
