26 **Commit message formatting is significant!!**
28 Please see `How to contribute <https://github.com/saltstack-formulas/.github/blob/master/CONTRIBUTING.rst>`_ for more details.
33 In the `Arvados repository <https://github.com/arvados/arvados/>`_ you can find `a provision script <https://github.com/arvados/arvados/tree/master/tools/salt-install>`_
34 to deploy a single-node, all-in-one Arvados cluster (The script uses this formula to get a cluster up and running in Saltstack's master-less mode).
36 The `single-node` install does not include SLURM: it is intended for an `all-in-one-host` installation,
37 so it uses `crunch-dispatch-local` to run containers in the same instance.
39 The provision script can be run anywhere, so you can run it in an AWS instance and you'll get a `single-node` Arvados cluster there.
41 The Arvados formula allows you to `install any dispatcher available <https://github.com/saltstack-formulas/arvados-formula/blob/master/pillar.example#L182-L191>`_,
42 provided you configure the pillars the way you need them.
44 Arvados currently has three dispatchers:
46 * **crunch-dispatch-local** (for single node installations and testing purposes, not suitable for production),
47 * **arvados-dispatch-cloud** (for dynamic compute on AWS or Azure) and
48 * **crunch-dispatch-slurm** (for SLURM integration).
53 Arvados **requires** a Postgres database for its API server and SSL for communications. If you don't satisfy these two requirements, things
54 won't work. It also uses an Nginx server as a redirector but probably almost any other webserver/redirector can be used instead.
56 We suggest you use the `postgres-formula <https://github.com/saltstack-formulas/postgres-formula/>`_,
57 the `nginx-formula <https://github.com/saltstack-formulas/nginx-formula/>`_ and the
58 `letsencrypt-formula <https://github.com/saltstack-formulas/letsencrypt-formula/>`_ to satisfy these dependencies.
59 In the **test/salt/pillar/examples/** directory there are example pillar YAMLs to set up these packages, using the mentioned formulas
60 as Arvados needs them.a
62 In the **test/salt/states/examples/** directory there are some example helper states to set up a few requirements for single-node
63 (all-in-one) Arvados host.
68 As Arvados is a *suite* of tools that can be installed in different hosts and configured to interact, this formula is split in
69 those components, which can be installed or removed independently of the other components. This means that you'll get flexibility
70 to install your cluster as you prefer at the expense of having to take care on some steps:
72 The formula has the following components/submodules available:
74 * `api <https://doc.arvados.org/install/install-api-server.html>`_: installs the Arvados API server packages. Requires a running
75 Postgres database and an Nginx+Passenger server.
76 * `config <https://doc.arvados.org/v2.0/admin/config.html>`_: creates and deploys a valid Arvados config file. This state is automatically
77 include in all the components that require it (at the moment, all but `shell`), so you will rarely need to invoke this state manually.
78 * `controller <https://doc.arvados.org/v2.0/install/install-api-server.html>`_: installs the Arvados API controller.
79 * `keepproxy <https://doc.arvados.org/v2.0/install/install-keepproxy.html>`_: installs and configures the Arvados Keepproxy gateway
81 * `keepstore <https://doc.arvados.org/v2.0/install/install-keepstore.html>`_: installs and configures an Arvados Keep storages.
82 * `keepweb <https://doc.arvados.org/v2.0/install/install-keep-web.html>`_: installs and configures the WebDAV access to the Keep storages.
83 * `repo <https://doc.arvados.org/v2.0/install/packages.html>`_: configures the repositories to install arvados. It's enabled by default.
84 * `shell <https://doc.arvados.org/v2.0/install/install-shell-server.html>`_: installs the user CLI apps to communicate with the cluster.
85 * `websocket <https://doc.arvados.org/v2.0/install/install-ws.html>`_: installs the websocket notifcations gateway.
86 * `workbench <https://doc.arvados.org/v2.0/install/install-workbench-app.html>`_: installs the webUI to communicate with the cluster.
87 * `workbench2 <https://doc.arvados.org/v2.0/install/install-workbench2-app.html>`_: installs the next generation webUI for Arvados.
89 If you just use the `arvados` meta-state, it will install all the components in a single host.
91 Also, please note that the individual subcomponents' `clean` states **won't remove the config file**: as the config is common to all the suite
92 components and they can be installed in the same host, removing it with a subcomponent might break others.
94 If you want to remove the config in a host where you're removing a subcomponent, use the `arvados.config.clean` state after the
95 `arvados.<subcomponent>.clean` state.
97 Finally, the `arvados.clean` meta-state will remove everything, config included, and can be used in any host to remove all of arvados files.
102 For each of the components, there are *meta-states* named after the component that will include other states in the component subdir
103 that perform the actual work.
105 For example, using *arvados.keepstore* will include, in order:
107 * arvados.keepstore.package.install
108 * arvados.config.file
109 * arvados.keepstore.service.running
111 while using *arvados.keepstore.clean* will include, in order:
113 * arvados.keepstore.service.clean
114 * arvados.keepstore.package.clean
116 Or you can use individual states, like
118 * arvados.keepstore.package.install
119 * arvados.keepstore.service.clean
121 to get the *keepstore* package installed with the service stopped.
123 The generic description for the states is
131 *Meta-state (This is a state that includes other states)*.
133 This installs the *WHOLE* arvados suite in a single host,
134 manages the arvados configuration file and then
135 starts the associated arvados services.
140 *Meta-state (This is a state that includes other states)*.
142 This state will undo everything performed in the ``arvados`` meta-state in reverse order, i.e.
143 stops the services, removes the configuration file and then uninstalls the packages.
149 This state will configure the arvados cluster. As all the arvados components use the same config
150 file, any of the following components will include this state and you will rarely need to call it
151 independently. You can still do, ie, to get a parsed config file to use somewhere else.
153 ``arvados.config.clean``
154 ^^^^^^^^^^^^^^^^^^^^^^^^^
156 This state will remove the configuration of the arvados node.
161 This state will configure the arvados repository.
163 ``arvados.repo.clean``
164 ^^^^^^^^^^^^^^^^^^^^^^
166 This state will remove the arvados repository configuration.
169 ``arvados.<component>``
170 ^^^^^^^^^^^^^^^^^^^^^^^
172 *Meta-state (This is a state that includes other states)*.
174 This state will install the package, configure the component (if applicable) and start the service (if applicable).
176 ``arvados.<component>.clean``
177 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
179 *Meta-state (This is a state that includes other states)*.
181 This state will undo everything performed in the ``arvados.<component>`` meta-state in reverse order, i.e.
182 stop the service and uninstall the package/s.
184 ``arvados.<component>.package``
185 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
187 This state will install the arvados <component> package/s only.
189 ``arvados.<component>.package.clean``
190 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
192 This state will remove the packages of the arvados <component> node and has a depency on
193 ``arvados.<component>.service.clean`` via include list (if applicable).
195 ``arvados.<component>.service``
196 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
198 This state will start the arvados service and has a dependency on ``arvados.config``
201 ``arvados.<component>.service.clean``
202 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
204 This state will stop the arvados service and disable it at boot time.
210 Linux testing is done with ``kitchen-salt``.
220 $ gem install bundler
222 $ bin/kitchen test [platform]
224 Where ``[platform]`` is the platform name defined in ``kitchen.yml``,
225 e.g. ``debian-10-3000-1-py3``.
227 ``bin/kitchen converge``
228 ^^^^^^^^^^^^^^^^^^^^^^^^
230 Creates the docker instance and runs the ``arvados`` main state, ready for testing.
232 ``bin/kitchen verify``
233 ^^^^^^^^^^^^^^^^^^^^^^
235 Runs the ``inspec`` tests on the actual instance.
237 ``bin/kitchen destroy``
238 ^^^^^^^^^^^^^^^^^^^^^^^
240 Removes the docker instance.
245 Runs all of the stages above in one go: i.e. ``destroy`` + ``converge`` + ``verify`` + ``destroy``.
247 ``bin/kitchen login``
248 ^^^^^^^^^^^^^^^^^^^^^
250 Gives you SSH access to the instance for manual testing.
