SSH Instance Access
Set up an ssh key, and add it to the current user’s authorized keys.
cd sshgen -f company # set it up with no password cat company.pub >> .ssh/authorized_keys # make sure to save off the public and private keys. One way: aws s3 cp company s3://my-bucket/company aws s3 cp company.pub s3://my-bucket/company.pub

Situation: You spin up a Linux instance with an additional drive, which you would like to access as /data.
sudo -i #if necessary lsblk #if necessary mkfs -t ext4 /dev/xvdb mkdir /data sudo mount /dev/xvdb /data cp /etc/fstab /etc/fstab.orig echo "/dev/xvdb /data ext4 defaults,nofail 0 2" >> /etc/fstab mount -a #test
Basic Run Script
If your linux dist uses Upstart, put something like this into /etc/init/myapp.conf.
