After spending a number of hours configuring an EC2 machine
id_rsa.pub > authorised_keys
id_rsa.pub >> authorised_keys
Panic!
Just lost all the configuration. To make matters worse, I hadn’t done a push to github. Was I just about to lose all my effort?
Thankfully, with some black magic I got the box back. One of the beautys of EC2 is the AMI. Exact machine images, yet modified with your own private key at create – exactly what I needed.
Stop machine
Create Image
Update with private key
Start.
IT WORKED LIKE A DREAM!
Couple of things like the hostname had been changed, but apart from that it was back and with all the configuration as I felt it – yet I could login. Wonderful.
