Overview
|
|
========
|
|
|
|
While creating an image is the preferred method for providing a base
|
|
for the Guest Instance, there may be cases where creating an image
|
|
is impractical. In those cases a Guest instance can be based on
|
|
an available Cloud Image and configured at boot via cloud-init.
|
|
|
|
Currently the most tested Guest image is Ubunutu 14.04 (trusty).
|
|
|
|
Setting up the Image
|
|
====================
|
|
|
|
* Visit the `Ubuntu Cloud Archive <https://cloud-images.ubuntu.com/releases/trusty/release>`_ and download ``ubuntu-14.04-server-cloudimg-amd64-disk1.img``.
|
|
|
|
* Upload that image to glance, and note the glance ID for the image.
|
|
|
|
* Cloud-Init files go into the directory set by the ``cloudinit_location``
|
|
configuration parameter, usually ``/etc/trove/cloudinit``. Files in
|
|
that directory are of the format ``[datastore].cloudinit``, for
|
|
example ``mysql.cloudinit``.
|
|
|
|
* Create a cloud-init file for your datastore and put it into place.
|
|
For this example, it is assumed you are using Ubuntu 16.04, with
|
|
the MySQL database and a Trove Agent from the Pike release. You
|
|
would put this into ``/etc/trove/cloudinit/mysql.cloudinit``.
|
|
|
|
.. code-block:: console
|
|
|
|
#cloud-config
|
|
# For Ubuntu-16.04 cloudimage
|
|
apt_sources:
|
|
- source: "cloud-archive:pike"
|
|
packages:
|
|
- trove-guestagent
|
|
- mysql-server-5.7
|
|
write_files:
|
|
- path: /etc/sudoers.d/trove
|
|
content: |
|
|
Defaults:trove !requiretty
|
|
trove ALL=(ALL) NOPASSWD:ALL
|
|
runcmd:
|
|
- stop trove-guestagent
|
|
- cat /etc/trove/trove-guestagent.conf /etc/trove/conf.d/guest_info.conf >/etc/trove/trove.conf
|
|
- start trove-guestagent
|
|
|
|
|
|
* If you need to debug guests failing to launch simply append
|
|
the cloud-init to add a user to allow you to login and
|
|
debug the instance.
|
|
|
|
* When using ``trove-manage datastore_version_update`` to
|
|
define your datastore simply use the Glance ID you have for
|
|
the Trusty Cloud image.
|
|
|
|
When trove launches the Guest Instance, the cloud-init will install
|
|
the Pike Trove Guest Agent and MySQL database, and then adjust
|
|
the configuration files and launch the Guest Agent.
