TurnKey Linux Virtual Appliance Library

Announcing TurnKey OpenStack optimized builds

OpenStack Logo

As we mentioned before, making TurnKey easy to deploy on as many public and private clouds is an important goal for us. Unfortunately there are too many players in the cloud software space for us to support every single one. It's much easier to put effort into making TurnKey work well with the winning horses.

TurnKey has been supported on the leading public cloud platform Amazon EC2 from early on, not to mention simplifying management and deployment via the Hub.

OpenStack is particularly interesting, because as it is most likely the future of open source clouds.

I originally got intrigued when I heard about NASA planning to open source Nebula in 2009, which has become the basis for Nova, the compute component in OpenStack. Since then, I've been following OpenStack development from a far and have been itching to develop support for TurnKey on the platform.

The time has finally arrived, and I'm pleased to announce TurnKey optimized builds are hot out of our build farm, and available for immediate download and deployment.

You can get them from the "Download -> More Builds" link on the appliance pages.

TurnKey OpenStack optimized builds

  • EBS auto-mounting support: we've updated our custom EBSmount mechanism for OpenStack, which automatically mounts EBS devices when attached.
  • Support for automating instance setup: via the user-data scripts mechanism.
  • Automatic APT configuration on boot: saves bandwidth costs by using the closest package archive for maximum performance.
  • SSH key support: instances that are launched with a key-pair will be configured accordingly.
  • SSH host key fingerprints displayed in system log: verification of server to prevent man-in-the-middle (mitm) attacks.
  • Randomly generated root password: is set on first boot, and displayed in the system log **.
  • Randomly generated mysql/postgres passwords: the MySQL root and/or PostgreSQL postgres passwords are set to to the same random password as root **.
  • Instance metadata python library and CLI: used internally, but useful for advanced users. (learn more).

** Because OpenStack builds are used in headless deployments (without a console), they include an inithook which preseeds default values, and random passwords:

/usr/lib/inithooks/firstboot.d/29preseed

MASTERPASS=$(mcookie | cut --bytes 1-8)

cat>$INITHOOKS_CONF<<EOF
export ROOT_PASS=$MASTERPASS
export DB_PASS=$MASTERPASS
export APP_PASS=turnkey
export APP_EMAIL=admin@example.com
export APP_DOMAIN=DEFAULT
export HUB_APIKEY=SKIP
export SEC_UPDATES=FORCE

Depending on your use case, you can utilize user-data (note the security implications) to preseed during boot, or once the system has booted by executing turnkey-init.

Exemplary import of TurnKey Core on OpenStack

There are several ways of uploading an image into an OpenStack deployment, below is one way to get you started.


# cd /tmp
# tar -zxf turnkey-core-11.3-lucid-x86-openstack.tar.gz
# ls turnkey-core-11.3-lucid-x86
    turnkey-core-11.3-lucid-x86-initrd
    turnkey-core-11.3-lucid-x86-kernel
    turnkey-core-11.3-lucid-x86.img

# IMG=turnkey-core-11.3-lucid-x86

# glance add -A $GLANCE_TOKEN \
    is_public=true \
    container_format=aki \
    disk_format=aki \
    name="$IMG-kernel" \
    < /tmp/$IMG/$IMG-kernel

Added new image with ID: 5

    container_format=ami \
    disk_format=ami \
    kernel_id=$KERNEL_ID \
    name="$IMG" \
    < /tmp/$IMG/$IMG.img

Great guys!

I'll be downloading/testing some of the appliances by the weekend and come back with some feedback. It's very nice to have the TKL arsenal at my disposal in openstack.

Nice one Alon

I have heard a bit about this tech. And although I'm very happy with my PVE server (especially now it has the TKL library in OVZ at my fingertips!) I might have to set up a testing OpenStack server perhaps to have a look at what all the fuss is about!

Looking forward to hearing about your experience Adrian.

Keep up the great work guys! :)

Sweet!

Going to spin up an instance at Rackspace and give it a try :-)

You guys rock!


Did it work?

Hi flexbean, did you ever get this to work with Rackspace? Wanna share your experience?

TurnKey Core 12.0rc available for OpenStack

Following the announcement of TurnKey Core 12.0rc (ISO, Amazon EC2, OpenVZ), we've released an OpenStack optimized build (download).

Please note that TKL 12.0 (based on Debian Squeeze) requires the initrd for deployment in OpenStack, for example:

# cd /tmp
# tar -zxf turnkey-core-12.0rc2-squeeze-x86-openstack.tar.gz
# ls turnkey-core-12.0rc2-squeeze-x86
    turnkey-core-12.0rc2-squeeze-x86-initrd
    turnkey-core-12.0rc2-squeeze-x86-kernel
    turnkey-core-12.0rc2-squeeze-x86.img

# IMG=turnkey-core-12.0rc2-squeeze-x86

# glance add -A $GLANCE_TOKEN \
    is_public=true \
    container_format=ari \
    disk_format=ari \
    name="$IMG-initrd" \
    < /tmp/$IMG/$IMG-initrd

Added new image with ID: 16

# RAMDISK_ID=16

# glance add -A $GLANCE_TOKEN \
    is_public=true \
    container_format=aki \
    disk_format=aki \
    name="$IMG-kernel" \
    < /tmp/$IMG/$IMG-kernel

Added new image with ID: 17

# KERNEL_ID=17

# glance add -A $GLANCE_TOKEN \
    is_public=true \
    container_format=ami \
    disk_format=ami \
    ramdisk_id=$RAMDISK_ID \
    kernel_id=$KERNEL_ID \
    name="$IMG" \
    < /tmp/$IMG/$IMG.img

Added new image with ID: 18

 

If you come across any issues, or have ideas on improving the optimized build, please post a comment.

Thanks Alon!

I was missing the initrd part. I'll try that and see how it goes...

unable to register openstack core at folsom

I made a test env on my ubuntu 12.10 with using devstack script.

The command:

glance add -A $GLANCE_TOKEN is_public=true container_format=ari disk_format=ari name="$IMG-initrd" < /tmp/$IMG/$IMG-initrd

gaves me: glance: error: unrecognized arguments: -A 

Without -A gaves me:

You must provide a username via either --os-username or env[OS_USERNAME]

Any clue?

failed to add an image.

Hi,

I am sutiing devstack and tried to add an icescrum appliance turnkey-icescrum-12.0, but i got

I used the script turnke2glance.sh
