Burn an AMI

# Fix:
#  /etc/hosts
#  /etc/hostname
#  /etc/fstab

# Nuke files that would be inconvenient to persist: chef config and startup files; log files; and files that contain keys of some sort.

Burning an EBS-backed AMI

Just use the console. MAKE SURE TO STOP, UNMOUNT AND DETACH ALL EBS volumes first.

Burning an Instance-backed (s3) AMIs

From your local machine, bring over your credentials

  scp -i ~/.hadoop-ec2/keypairs/hoolock.pem ~/.hadoop-ec2/{certs/cert.pem,certs/pk.pem,keypairs/hoolock.pem} ubuntu@

On the target machine:

cd /mnt
eval $(sudo blkid /dev/sda1 | awk -F: '{ print $2 }') 
# credentials
AWS_ACCOUNT_ID=123456781234 AWS_ACCESS_KEY_ID=2341245 AWS_SECRET_ACCESS_KEY=125324635473465743674637
# ... move the keys to /mnt (so that they are ignored in the bundling)
sudo mv /tmp/*.pem /mnt

Modify the following to suit. (A note about AMI_EXCLUDES: the ec2-bundle-vol
will complain about excluded dirs that don’t exist — remove those. Be careful
though, because it is a VERY BAD THING if directories that do exist (say, a
500GB attached drive) aren’t excluded!)

# edit these:
# i386 or x86_64
# might need to add: /ebs1,/ebs2,/data,/var/lib/cassandra,/srv/chef/cache

export EC2_CERT=/mnt/cert.pem
export EC2_PRIVATE_KEY=/mnt/pk.pem
kern=$(wget -q -O -) ; echo $kern
eval `cat /etc/lsb-release `
ami_name=infochimps.chef-client.${DISTRIB_CODENAME}.east.ami-${BITS}-`date "+%Y%m%d"`
sudo mkdir -p /mnt/$ami_bucket

# This will take a long fucking time. 15 minutes on a small instance. It fucking sucks.
time sudo ec2-bundle-vol --kernel $kern --exclude=$AMI_EXCLUDES -r $BITS -d /mnt/$ami_bucket -u $AWS_ACCOUNT_ID --cert cert.pem --privatekey pk.pem --ec2cert /etc/ec2/amitools/cert-ec2.pem

( cd /mnt/$ami_bucket ; ec2-unbundle --manifest image.manifest.xml --destination /mnt --privatekey $EC2_PRIVATE_KEY  )

time ec2-bundle-image --image /mnt/image --kernel $kern -u $AWS_ACCOUNT_ID --cert cert.pem --privatekey pk.pem --ec2cert /etc/ec2/amitools/cert-ec2.pem

time ec2-upload-bundle    -b $ami_bucket -m /mnt/$ami_bucket/image.manifest.xml -a $AWS_ACCESS_KEY_ID -s $AWS_SECRET_ACCESS_KEY

If you are in a region other than us-east-1

  1. export AWS_REGION=us-west-1

  3. sudo mkdir -p /mnt/$ami_bucket
  4. time sudo ec2-bundle-vol —exclude=$AMI_EXCLUDES -d /mnt/$ami_bucket -u $AWS_ACCOUNT_ID —cert cert.pem —privatekey pk.pem —ec2cert /etc/ec2/amitools/cert-ec2.pem
