47 Arvados **requires** a Postgres database for its API server and SSL for communications. If you don't satisfy these two requirements, things
48 won't work. It also uses an Nginx server as a redirector but probably almost any other webserver/redirector can be used instead.
50 We suggest you use the `postgres-formula <https://github.com/saltstack-formulas/postgres-formula/>`_,
51 the `nginx-formula <https://github.com/saltstack-formulas/nginx-formula/>`_ and the
52 `letsencrypt-formula <https://github.com/saltstack-formulas/letsencrypt-formula/>`_ to satisfy these dependencies.
53 In the **test/salt/pillar/examples/** directory there are example pillar YAMLs to set up these packages, using the mentioned formulas
54 as Arvados needs them.
59 As Arvados is a *suite* of tools that can be installed in different hosts and configured to interact, this formula is split in
60 those components, which can be installed or removed independently of the other components. This means that you'll get flexibility
61 to install your cluster as you prefer at the expense of having to take care on some steps:
63 The formula has the following components/submodules available:
65 * `api <https://doc.arvados.org/install/install-api-server.html>`_: installs the Arvados API server packages. Requires a running
66 Postgres database and an Nginx+Passenger server.
67 * `config <https://doc.arvados.org/v2.0/admin/config.html>`_: creates and deploys a valid Arvados config file. This state is automatically
68 include in all the components that require it (at the moment, all but `shell`), so you will rarely need to invoke this state manually.
69 * `controller <https://doc.arvados.org/v2.0/install/install-api-server.html>`_: installs the Arvados API controller.
70 * `keepproxy <https://doc.arvados.org/v2.0/install/install-keepproxy.html>`_: installs and configures the Arvados Keepproxy gateway
72 * `keepstore <https://doc.arvados.org/v2.0/install/install-keepstore.html>`_: installs and configures an Arvados Keep storages.
73 * `keepweb <https://doc.arvados.org/v2.0/install/install-keep-web.html>`_: installs and configures the WebDAV access to the Keep storages.
74 * `repo <https://doc.arvados.org/v2.0/install/packages.html>`_: configures the repositories to install arvados. It's enabled by default.
75 * `shell <https://doc.arvados.org/v2.0/install/install-shell-server.html>`_: installs the user CLI apps to communicate with the cluster.
76 * `websocket <https://doc.arvados.org/v2.0/install/install-ws.html>`_: installs the websocket notifcations gateway.
77 * `workbench <https://doc.arvados.org/v2.0/install/install-workbench-app.html>`_: installs the webUI to communicate with the cluster.
78 * `workbench2 <https://doc.arvados.org/v2.0/install/install-workbench2-app.html>`_: installs the next generation webUI for Arvados.
80 If you just use the `arvados` meta-state, it will install all the components in a single host.
82 Also, please note that the individual subcomponents' `clean` states **won't remove the config file**: as the config is common to all the suite
83 components and they can be installed in the same host, removing it with a subcomponent might break others.
85 If you want to remove the config in a host where you're removing a subcomponent, use the `arvados.config.clean` state after the
86 `arvados.<subcomponent>.clean` state.
88 Finally, the `arvados.clean` meta-state will remove everything, config included, and can be used in any host to remove all of arvados files.
93 For each of the components, there are *meta-states* named after the component that will include other states in the component subdir
94 that perform the actual work.
96 For example, using *arvados.keepstore* will include, in order:
98 * arvados.keepstore.package.install
100 * arvados.keepstore.service.running
102 while using *arvados.keepstore.clean* will include, in order:
104 * arvados.keepstore.service.clean
105 * arvados.keepstore.package.clean
107 Or you can use individual states, like
109 * arvados.keepstore.package.install
110 * arvados.keepstore.service.clean
112 to get the *keepstore* package installed with the service stopped.
114 The generic description for the states is
122 *Meta-state (This is a state that includes other states)*.
124 This installs the *WHOLE* arvados suite in a single host,
125 manages the arvados configuration file and then
126 starts the associated arvados services.
131 *Meta-state (This is a state that includes other states)*.
133 This state will undo everything performed in the ``arvados`` meta-state in reverse order, i.e.
134 stops the services, removes the configuration file and then uninstalls the packages.
140 This state will configure the arvados cluster. As all the arvados components use the same config
141 file, any of the following components will include this state and you will rarely need to call it
142 independently. You can still do, ie, to get a parsed config file to use somewhere else.
144 ``arvados.config.clean``
145 ^^^^^^^^^^^^^^^^^^^^^^^^^
147 This state will remove the configuration of the arvados node.
152 This state will configure the arvados repository.
154 ``arvados.repo.clean``
155 ^^^^^^^^^^^^^^^^^^^^^^
157 This state will remove the arvados repository configuration.
160 ``arvados.<component>``
161 ^^^^^^^^^^^^^^^^^^^^^^^
163 *Meta-state (This is a state that includes other states)*.
165 This state will install the package, configure the component (if applicable) and start the service (if applicable).
167 ``arvados.<component>.clean``
168 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
170 *Meta-state (This is a state that includes other states)*.
172 This state will undo everything performed in the ``arvados.<component>`` meta-state in reverse order, i.e.
173 stop the service and uninstall the package/s.
175 ``arvados.<component>.package``
176 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
178 This state will install the arvados <component> package/s only.
180 ``arvados.<component>.package.clean``
181 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
183 This state will remove the packages of the arvados <component> node and has a depency on
184 ``arvados.<component>.service.clean`` via include list (if applicable).
186 ``arvados.<component>.service``
187 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
189 This state will start the arvados service and has a dependency on ``arvados.config``
192 ``arvados.<component>.service.clean``
193 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
195 This state will stop the arvados service and disable it at boot time.
201 Linux testing is done with ``kitchen-salt``.
211 $ gem install bundler
213 $ bin/kitchen test [platform]
215 Where ``[platform]`` is the platform name defined in ``kitchen.yml``,
216 e.g. ``debian-10-3000-1-py3``.
218 ``bin/kitchen converge``
219 ^^^^^^^^^^^^^^^^^^^^^^^^
221 Creates the docker instance and runs the ``arvados`` main state, ready for testing.
223 ``bin/kitchen verify``
224 ^^^^^^^^^^^^^^^^^^^^^^
226 Runs the ``inspec`` tests on the actual instance.
228 ``bin/kitchen destroy``
229 ^^^^^^^^^^^^^^^^^^^^^^^
231 Removes the docker instance.
236 Runs all of the stages above in one go: i.e. ``destroy`` + ``converge`` + ``verify`` + ``destroy``.
238 ``bin/kitchen login``
239 ^^^^^^^^^^^^^^^^^^^^^
241 Gives you SSH access to the instance for manual testing.
