When I log in after trying to debug something I find that the command prompt gives me the following:
|
1 2 3 4 5 |
core@ci ~ $ ssh -i tco-gold.pem core@10.2.3.6 Last login: Wed May 27 19:45:10 2015 from 10.2.3.7 CoreOS stable (633.1.0) Failed Units: 1 coreos-cloudinit-547659032.service |
So to figure out where my script went wrong, I simply have to run the command:
|
1 |
systemctl status -l <name of service> |
So in my case it was:
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 |

It turns out, I put an extra ssh-keyscan in the the script and it thought it was the hostname!
Removing the extra characters worked.
