h1. Setting up an arvbox dev federation

For development of federation features, you can run multiple arvbox instances and configure them for federation.

Make sure you have the latest 'arvbox' script and arvbox-dev image.

<pre>

curl -O https://raw.githubusercontent.com/curoverse/arvados/master/tools/arvbox/bin/arvbox

chmod +x arvbox

docker pull arvados/arvbox-dev

</pre>

h2. Create two arvbox instances

<pre>

$ export ARVBOX_CONTAINER=cluster1

$ arvbox start dev

$ export ARVBOX_CONTAINER=cluster2

$ arvbox start dev

</pre>

Make note of the cluster ids and IP addresses.  In this example cluster1 is 1b7fr and cluster2 is 2gvh8.

Note that Docker assigns IP addresses sequentially.  To ensure you get the same IP addresses each time you'll need to start cluster1 first, followed by cluster2, and you don't want any other containers running.  Your cluster ids will be different than this example.

h2. Set configuration overrides

Create ~/.arvbox/cluster1/var/cluster_config.yml.override

<pre>

Clusters:

  1b7fr:  # cluster1 id

    RemoteClusters:

      1b7fr:

        Host: 172.17.0.2:8000

        Proxy: true

      2gvh8:

        Host: 172.17.0.3:8000

        Proxy: true

</pre>

Create ~/.arvbox/cluster2/var/cluster_config.yml.override

<pre>

Clusters:

  2gvh8:  # cluster2 id

    RemoteClusters:

      1b7fr:

        Host: 172.17.0.2:8000

        Proxy: true

      2gvh8:

        Host: 172.17.0.3:8000

        Proxy: true

</pre>

h2. Copy root certificates

<pre>

docker cp ~/.arvbox/cluster2/var/arvbox2-root-cert.crt cluster1:/usr/local/share/ca-certificates/

docker cp ~/.arvbox/cluster1/var/arvbox-root-cert.crt cluster2:/usr/local/share/ca-certificates/

docker exec cluster1 update-ca-certificates

docker exec cluster2 update-ca-certificates

</pre>

You probably also want to install the root certificates on the host: https://doc.arvados.org/install/arvbox.html

h2. Restart services

<pre>

$ export ARVBOX_CONTAINER=cluster1

$ arvbox sv restart api

$ arvbox sv restart controller

$ arvbox sv restart keepstore0

$ arvbox sv restart keepstore1

$ export ARVBOX_CONTAINER=cluster2

$ arvbox sv restart api

$ arvbox sv restart controller

$ arvbox sv restart keepstore0

$ arvbox sv restart keepstore1

</pre>

h2. Testing

# Visit workbench2 at 172.17.0.2:3001 and create a user account.

# Copy the token

# Visit workbench2 at 172.17.0.3:3001 and specify "log in with user from cluster1"

# You should be logged into workbench on the cluster2 with the user from cluster1

At the command line:

<pre>

$ export ARVADOS_API_HOST=172.17.0.3:8000

$ export ARVADOS_API_TOKEN=token_copied_in_previous_step

$ arv user current

</pre>

This shows cluster2 accepting a token for cluster1.  Look for the "writable_by" field in the response including uuids with both cluster1 and cluster2.
