Some advanced or ui features +are optional and can be installed separately. Kamaki behavior can be configured in +the kamaki config file. + +Quick Setup +----------- + +Existing kamaki users should consult the +`migration guide <#migrating-from-kamaki-0-8-x-to-0-9>`_ first. + +Kamaki has to be configured for a specific Synnefo deployment, with an +authentication url and user token pair. Users should also pick an alias to name +the cloud configuration. This can be any single word, e.g. "default", "mycloud" +or whatever suits kamaki users. + +.. code-block:: console + + $ kamaki config set cloud..url + $ kamaki config set cloud..token myt0k3n== + +If only one cloud is configured, kamaki automatically picks it as the default. +Otherwise, a default cloud should be specified: + +.. code-block:: console + + $ kamaki config set default_cloud + +Since Synnefo version 0.14, a synnefo cloud UI offers a single authentication +URL, which should be set as the cloud URL for kamaki. All service-specific URLs +are retrieved and handled automatically by kamaki, through this URL. Users of +synnefo clouds >=0.14 are advised against using any service-specific URLs. + +Migrating from kamaki 0.8.X to 0.9 +---------------------------------- + +This section refers to running installations of kamaki version <= 0.8.X To +check the current kamaki version: + +.. code-block:: console + + $ kamaki -V + +Existing kamaki users should convert their configuration files to v9. To do +that, kamaki 0.9 can inspect the configuration file and suggests a list of +config file transformations, which are performed automatically (after users' +permission). This mechanism is invoked when an API-related kamaki command is +fired. On example 2.1 we suggest using the `user authenticate` command to fire +the kamaki config file conversion mechanism. + +.. code-block:: console + :emphasize-lines: 1 + + Example 2.1: Convert config file while authenticating user "exampleuser" + + $ kamaki user authenticate + Config file format version >= 9.0 is required + Configuration file: "/home/exampleuser/.kamakirc" + but kamaki can fix this: + Calculating changes while preserving information + ... rescue global.token => cloud.default.token + ... rescue config.cli => global.config_cli + ... rescue history.file => global.history_file + ...

[Y, y] + +At this point, we should examine the kamaki output. Most options are renamed to +be understood by the new kamaki. + +Let's take a look at the discarded options: + +* `global.account` and `user.account` are not used anymore. + The same is true for the synonyms `store.account` and `pithos.account`. + These options were used to explicitly set a user account or uuid to a + pithos call. In the latest Synnefo version (>= 0.14), these features are + meaningless and therefore omitted. + +* `global.data_log` option has never been a valid kamaki config option. + In this example, the user accidentally misspelled the term `log_data` + (which is a valid kamaki config option) as `data_log`. To fix this, the + user should set the correct option after the conversion is complete + (Example 2.2). + +Users should press *y* when they are ready. Kamaki has now modified the default +config file to conform with kamaki config file v3. Now users should rescue +unrescued information (if any). + +.. code-block:: console + :emphasize-lines: 1 + + Example 2.2: Rescue misspelled log_data option + + $ kamaki config set log_data on + +In order to convert more files, users may run kamaki with the -c option, which +runs kamaki with a different configuration file (Example 2.3) and apply the +steps described above. + +.. code-block:: console + :emphasize-lines: 1 + + Example 2.3: Use kamaki to update a configuration file called ".myfilerc" + + $ kamaki -c .myfilerc user authenticate + +Multiple clouds +--------------- + +The following refers to users of multiple Synnefo and/or Open Stack +deployments. In the following, a Synnefo or Open Stack cloud deployment will +frequently be called as a **cloud**. + +Kamaki supports accessing multiple clouds from the same kamaki setup. Before +kamaki 0.9, this was possible only by using multiple config files. Since 0.9, +kamaki supports multiple clouds in the same configuration. + +Each cloud corresponds to a Synnefo (or Open Stack) cloud deployment. +Since Synnefo version 0.14, each deployment offers a single point of +authentication, as an **authentication URL** and **token** pair. Users can +retrieve this information through the cloud UI. + +Once a user has retrieved one URL/token pair per cloud, it is time to assign a +name to each cloud and let kamaki know about them. + +For example, let the user have access to two clouds with the following authentication information :: + + cloud alias: devel + authentication URL: https://devel.example.com/astakos/identity/v2.0/ + authentication token: myd3v3170k3n== + + cloud alias: testing + autentication URL: https://testing.example.com/astakos/identity/v2.0/ + authentication token: my73571ng70k3n== + +.. note:: the cloud alias is arbitrary and decided by the user. It is just a + name to call a cloud setup in the kamaki context. + +The user should let kamaki know about these setups: + +.. code-block:: console + + $ kamaki config set cloud.devel.url https://devel.example.com/astakos/identity/v2.0/ + $ kamaki config set cloud.devel.token myd3v3170k3n== + $ + $ kamaki config set cloud.testing.url https://testing.example.com/astakos/identity/v2.0/ + $ kamaki config set cloud.testing.token my73571ng70k3n== + $ + +To check if all settings are loaded, a user may list all clouds, as shown +bellow: + +.. code-block:: console + + $ kamaki config getcloud + cloud.default.url = https://example.com/astakos.identity/v2.0/ + cloud.default.url = myd3f4u1770k3n== + cloud.devel.url = https://devel.example.com/astakos/identity/v2.0/ + cloud.devel.token = myd3v3170k3n== + cloud.testing.url = https://testing.example.com/astakos/identity/v2.0/ + cloud.testing.token = my73571ng70k3n== + $ + +or query kamaki for a specific cloud: + +.. code-block:: console + + $ kamaki config get cloud.devel + cloud.devel.url = https://devel.example.com/astakos/identity/v2.0/ + cloud.devel.token = myd3v3170k3n== + $ + +Now kamaki can use any of these clouds, with the **- - cloud** attribute.
