h2(#configure). Update config.yml

Edit @/etc/arvados/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:
      Workbench:
        ExternalURL: <span class="userinput">"https://workbench.ClustedID.example.com"</span>
    Workbench:
      SecretKeyBase: <span class="userinput">aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa</span>
    Users:
      AutoAdminFirstUser: true
</code></pre>
</notextile>

This application needs a secret token. Generate a new secret:

<notextile>
<pre><code>~$ <span class="userinput">ruby -e 'puts rand(2**400).to_s(36)'</span>
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
</code></pre>
</notextile>

Then put that value in the @Workbench.SecretKeyBase@ field.

You probably want to enable @Users.AutoAdminFirstUser@ .  The first user to log in when no other admin user exists will automatically be made an admin.

h2(#update-nginx). Update nginx configuration

Use a text editor to create a new file @/etc/nginx/conf.d/arvados-workbench.conf@ with the following configuration.  Options that need attention are marked with "TODO".

<notextile>
<pre><code>server {
  listen       <span class="userinput">[your public IP address]</span>:443 ssl;
  server_name  workbench.<span class="userinput">ClusterID.example.com</span>;

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

  root /var/www/arvados-workbench/current/public;
  index  index.html;

  passenger_enabled on;
  # If you're using RVM, uncomment the line below.
  #passenger_ruby /usr/local/rvm/wrappers/default/ruby;

  # `client_max_body_size` should match the corresponding setting in
  # the API.MaxRequestSize and Controller's server's Nginx configuration.
  client_max_body_size 128m;
}
</code></pre>
</notextile>

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

{% include 'install_packages' %}

{% include 'restart_api' %}

h2(#confirm-working). Confirm working installation

Visit @https://workbench.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>
