In certain cases, the cloud-init service might stop and that would cause the AWS instance to not boot. Use the following steps to recover:<\/p>\n\n\n\n

  1. Launch a new recovery instance of type t2.micro(x86x64) in the same Availability Zone (ie us-east-1a). Ensure that you enable a public ip or associate an elastic ip with this recovery instance to access internet.<\/li>
  2. Detach the root volume of the impaired instance <\/li>
  3. Attach the volume as a secondary volume to the recovery instance.<\/li>
  4. SSH into the recovery instance and mount the volume the secondary volume.
    # sudo su <\u2014\u2014\u2014\u2014\u2014\u2014 become a root user.
    # sudo mkdir \/mnt\/recovery <\u2014\u2014\u2014\u2014\u2014\u2014 make a directory.
    # sudo mount \/dev\/xvdf1 \/mnt\/recovery <\u2014\u2014\u2014\u2014\u2014\u2014 Mount the secondary volume to the recovery instance.
    # mount -o bind \/proc \/mnt\/recovery\/proc
    # mount -o bind \/dev \/mnt\/recovery\/dev
    # mount -o bind \/sys \/mnt\/recovery\/sys
    # chroot \/mnt\/recovery # cd \/ # ll \/etc\/resolv.conf # rm -f \/etc\/resolv.conf # echo \"nameserver 8.8.8.8\" > \/etc\/resolv.conf # apt update # apt remove cloud-init # apt purge cloud-init -y # apt install cloud-init -y # cd \/var\/lib\/cloud\/ # rm -rf * # cd # exit <\u2014\u2014\u2014\u2014 we have come out of the chroot using exit command. # umount \/mnt\/recovery\/{proc,sys,dev} <\u2014\u2014\u2014\u2014 and now we have to unmount the secondary volume. # umount \/mnt\/recovery # lsblk <\u2014\u2014\u2014\u2014 to confirm if volume has been unmounted.<\/code><\/li>
  5. Now, you can detach the secondary volume and attach it to the original instance: as \/dev\/sda1.<\/li>
  6. Now, create a new AMI from the impaired instance and launch a new instance of your choice.<\/li><\/ol>\n\n\n\n
