Workbench2 is the web-based user interface for Arvados.

{% include 'notebox_begin' %}
Workbench2 is the replacement for Arvados Workbench. Workbench2 is suitable for day-to-day use, but does not yet implement every feature of the traditional Workbench.
{% include 'notebox_end' %}

h2(#configure). Update config.yml

Edit @config.yml@ to set the keys below.  The full set of configuration options are in the "Workbench section of config.yml":{{site.baseurl}}/admin/config.html

<notextile>
<pre><code>    Services:
      Workbench2:
        ExternalURL: <span class="userinput">"https://workbench2.ClusterID.example.com"</span>
</code></pre>
</notextile>

h2(#update-nginx). Update Nginx configuration

Workbench2 does not require its own database. It is a set of html, javascript and css files that are served as static files from Nginx.

Use a text editor to create a new file @/etc/nginx/conf.d/arvados-workbench2.conf@ with the following configuration.  Options that need attention are marked in <span class="userinput">red</span>.

<notextile>
<pre><code>server {
    listen       80;
    server_name  workbench2.<span class="userinput">ClusterID.example.com</span>;
    return 301   https://workbench2.<span class="userinput">ClusterID.example.com</span>$request_uri;
}

server {
  listen       443 ssl;
  server_name  workbench2.<span class="userinput">ClusterID.example.com</span>;

  ssl_certificate     <span class="userinput">/YOUR/PATH/TO/cert.pem</span>;
  ssl_certificate_key <span class="userinput">/YOUR/PATH/TO/cert.key</span>;

  index  index.html;

  # <span class="userinput">Workbench2 uses a call to /config.json to bootstrap itself</span>
  # <span class="userinput">and find out where to contact the API server.</span>
  location /config.json {
    return 200 '{ "API_HOST": "<span class="userinput">ClusterID.example.com</span>" }';
  }

  location / {
    root      /var/www/arvados-workbench2/workbench2;
    index     index.html;
    try_files $uri $uri/ /index.html;
    if (-f $document_root/maintenance.html) {
      return 503;
    }
  }
}
</code></pre>
</notextile>

h2. Vocabulary configuration

Workbench2 will load, if available, a vocabulary definition which lists available metadata properties for groups and collections.  To learn how to configure the property vocabulary definition, please visit the "Metadata Vocabulary Format":{{site.baseurl}}/admin/metadata-vocabulary.html page in the Admin section.

{% assign arvados_component = 'arvados-workbench2' %}

{% include 'install_packages' %}

{% include 'restart_api' %}

h2(#confirm-working). Confirm working installation

Visit @https://workbench2.ClusterID.example.com@ in a browser.  You should be able to log in using the login method you configured in the previous step.  If @Users.AutoAdminFirstUser@ is true, you will be an admin user.

h2(#trusted_client). Trusted client flag

Log in to Workbench once to ensure that the Arvados API server has a record of the Workbench client. (It's OK if Workbench says your account hasn't been activated yet. We'll deal with that next.)

In the <strong>API server</strong> project root, start the Rails console.  {% include 'install_rails_command' %}

At the console, enter the following commands to locate the ApiClient record for your Workbench installation (typically, while you're setting this up, the @last@ one in the database is the one you want), then set the @is_trusted@ flag for the appropriate client record:

<notextile><pre><code>irb(main):001:0&gt; <span class="userinput">wb = ApiClient.all.last; [wb.url_prefix, wb.created_at]</span>
=&gt; ["https://workbench.example.com/", Sat, 19 Apr 2014 03:35:12 UTC +00:00]
irb(main):002:0&gt; <span class="userinput">include CurrentApiClient</span>
=&gt; true
irb(main):003:0&gt; <span class="userinput">act_as_system_user do wb.update_attributes!(is_trusted: true) end</span>
=&gt; true
</code></pre>
