This tutorial describes how to find and copy a publicly shared pipeline from the Arvados Playground. Please note that you can use similar steps to copy any template you can access from the Arvados Playground to your cluster.

h3. Access a public pipeline in the Arvados Playground using Workbench

the Arvados Playground provides access to some public data, which can be used to experience Arvados in action. Let's access a public pipeline and copy it to your cluster, so that you can run it in your environment.

Start by visiting the "*Arvados Playground public projects page*":https://playground.arvados.org/projects/public. This page lists all the publicly accessible projects in this arvados installation. Click on one of these projects to open it. We will use "*lobSTR v.3 (Public)*":https://playground.arvados.org/projects/qr1hi-j7d0g-up6qgpqz5ie2vfq as the example in this tutorial.

Once in the "*lobSTR v.3 (Public)*":https://playground.arvados.org/projects/qr1hi-j7d0g-up6qgpqz5ie2vfq project, click on the *Pipeline templates* tab. In the pipeline templates tab, you will see a template named *lobSTR v.3*. Click on the <span class="fa fa-lg fa-gears"></span> *Show* button to the left of this name. This will take to you to the "*lobSTR v.3*":https://playground.arvados.org/pipeline_templates/qr1hi-p5p6p-9pkaxt6qjnkxhhu template page.

Once in this page, you can take the *uuid* of this template from the address bar, which is *qr1hi-p5p6p-9pkaxt6qjnkxhhu*. Next, we will copy this template to your Arvados instance.

h3. Copying a pipeline template from the Arvados Playground to your cluster

As described above, navigate to the publicly shared pipeline template "*lobSTR v.3*":https://playground.arvados.org/pipeline_templates/qr1hi-p5p6p-9pkaxt6qjnkxhhu on the Arvados Playground.  We will now copy this template with uuid *qr1hi-p5p6p-9pkaxt6qjnkxhhu* to your cluster.

{% include 'tutorial_expectations' %}

We will use the Arvados *arv-copy* command to copy this template to your cluster. In order to use arv-copy, first you need to setup the source and destination cluster configuration files. Here, *qr1hi* would be the source cluster and your Arvados instance would be the *dst_cluster*.

During this setup, if you have an account in the Arvados Playground, you can use "your access token":#using-your-token to create the source configuration file. If you do not have an account in the Arvados Playground, you can use the "anonymous access token":#using-anonymous-token for the source cluster configuration.

h4(#using-anonymous-token). *Configuring source and destination setup files using anonymous access token*

Configure the source and destination clusters as described in the "*Using arv-copy*":http://doc.arvados.org/user/topics/arv-copy.html tutorial in user guide, while using *5vqmz9mik2ou2k9objb8pnyce8t97p6vocyaouqo3qalvpmjs5* as the API token for source configuration.

<notextile>
<pre><code>~$ <span class="userinput">cd ~/.config/arvados</span>
~$ <span class="userinput">echo "ARVADOS_API_HOST=qr1hi.arvadosapi.com" >> qr1hi.conf</span>
~$ <span class="userinput">echo "ARVADOS_API_TOKEN=5vqmz9mik2ou2k9objb8pnyce8t97p6vocyaouqo3qalvpmjs5" >> qr1hi.conf</span>
</code></pre>
</notextile>

You can now copy the pipeline template from *qr1hi* to *your cluster*. Replace *dst_cluster* with the *uuid_prefix* of your cluster.

<notextile>
<pre><code>~$ <span class="userinput"> arv-copy --no-recursive --src qr1hi --dst dst_cluster qr1hi-p5p6p-9pkaxt6qjnkxhhu</span>
</code></pre>
</notextile>

*Note:* When you are using anonymous access token to copy the template, you will not be able to do a recursive copy since you will not be able to provide the dst-git-repo parameter. In order to perform a recursive copy of the template, you would need to use the Arvados API token from your account as explained in the "using your token":#using-your-token section below.

h4(#using-your-token). *Configuring source and destination setup files using personal access token*

If you already have an account in the Arvados Playground, you can follow the instructions in the "*Using arv-copy*":http://doc.arvados.org/user/topics/arv-copy.html user guide to get your *Current token* for source and destination clusters, and use them to create the source *qr1hi.conf* and dst_cluster.conf configuration files.

You can now copy the pipeline template from *qr1hi* to *your cluster* with or without recursion. Replace *dst_cluster* with the *uuid_prefix* of your cluster.

*Non-recursive copy:*
<notextile>
<pre><code>~$ <span class="userinput"> arv-copy --no-recursive --src qr1hi --dst dst_cluster qr1hi-p5p6p-9pkaxt6qjnkxhhu</span></code></pre>
</notextile>

*Recursive copy:*
<notextile>
<pre><code>~$ <span class="userinput">arv-copy --src qr1hi --dst dst_cluster --dst-git-repo $USER/tutorial qr1hi-p5p6p-9pkaxt6qjnkxhhu</span></code></pre>
