h2(#install_workbench). Install Workbench2 and dependencies

Workbench2 does not require its own database. It is a set of html, javascript and css files that are served as static files from a web server like Nginx or Apache2.

On a Debian-based system, install the following package:

<notextile>
<pre><code>~$ <span class="userinput">sudo apt-get install arvados-workbench2</span>
</code></pre>
</notextile>

On a Red Hat-based system, install the following package:

<notextile>
<pre><code>~$ <span class="userinput">sudo yum install arvados-workbench2</span>
</code></pre>
</notextile>

h2. Set up Web server

For best performance, we recommend you use Nginx as your Web server to serve Workbench2. Workbench2 consists entirely of static files. To do that:

<notextile>
<ol>
<li>Install Nginx</li>

<li><p>Edit the http section of your Nginx configuration to serve Workbench2's files. You might add a block like the following, adding SSL and logging parameters to taste:</p>

<pre><code>server {
  listen       <span class="userinput">[your public IP address]</span>:443 ssl;
  server_name  workbench2.<span class="userinput">uuid-prefix.your.domain</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>;

  index  index.html;

  # Workbench2 uses a call to /config.json to bootstrap itself and talk to the desired API server
  location /config.json {
    return 200 '{ "API_HOST": "<span class="userinput">uuid-prefix.your.domain</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>
</li>

<li>Restart Nginx.</li>

</ol>
</notextile>

h2. Trusted client setting

Log in to Workbench2 once to ensure that the Arvados API server has a record of the Workbench2 client.

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 Workbench2 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://workbench2.<span class="userinput">uuid_prefix.your.domain</span>/", Sat, 20 Apr 2019 01:23:45 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>
</notextile>
