This document describes changes and steps to upgrade from kamaki 0.8.X to

kamaki 0.9

Configuration file

------------------

Kamaki 0.9 uses a redesigned configuration file. The new configuration file

version is v3.

The new file consists of at least two groups: global and remote "default". The

global field holds all settings releated to kamaki client and cli

functionality. The remote "default" field holds authentication information for

connecting to the cloud.

A sample configuration file:

  # Kamaki configuration file v3 (kamaki >= v0.9)

  [global]

  colors = on

  [remote "default"]

  url = https://astakos.example.com/astakos/identity/v2.0/

  token = myu53r70k3n==

How to convert an old configuration file

----------------------------------------

When loading a kamaki command, kamaki inspect the configuration file. If the

configuration file is judged to be a valid v3 kamaki configuration file, the

kamaki command will be executed normally. Otherwise, kamaki will attempt to

convert the file.

Step 1: backup the kamaki configuraiton file ( usually $HOME/.kamakirc )

Step 2: Run a cloud kamaki command. We suggest the following:

  kamaki user authenticate

Step 3: Kamaki will create a list of suggested modifications. Users may permit

or deny these changes (y or n). To convert the file, press y .

In case of a denial, kamaki will exit. Otherwise the configuration file will

be converted.

Kamaki attempts to preserve as much information as possible, by performing

option renames and moving values under the correct groups. In any case,

kamaki prints on console all actions, whether modifications or deletions, so

that no information is lost.

Single authentication url

-------------------------

Since Synnefo version 0.14, cloud clients can be authenticated onb a single

URL, which is common for the whole cloud system. The authentication mechanism

provides all information nessecary for running any available cloud service.

Kamaki takes advantage of this feature, requiring users to remove all

service-specific settings and using a single authentication URL,token pair for

the whole cloud. This affects all CLI users, whether they use cyclades,

plankton or pithos.

For example, instead of this:

  [global]

  token = myu53r70k3n==

  [user]

  url = https://astakos.example.com/

  [file]

  url = https://pithos.example.com/pithos/v1

  container = image

  [image]

  url = https://image.example.com/plankton/v1

the new configuration file may look like this:

  [global]

  pithos_container = image

  [remote "default"]

  url = https://astakos.example.com/astakos/identity/v2.0/

  token = myu53r70k3n==

Kamaki will use the default url to authenticate the synnefo user and then it

will automatically retrieve the astakos, image and pithos urls needed for the

rest of the operations.
