+In a multi-host installation, containers are dispatched in docker daemons running in the <i>compute instances</i>, which need some special setup. We provide a "compute image builder script":https://github.com/arvados/arvados/tree/{{ branchname }}/tools/compute-images that you can use to build a template image following "these instructions":https://doc.arvados.org/install/crunch2-cloud/install-compute-node.html. Once you have that image created, you will need to update the <i>pillars/arvados.sls</i> file with the AMI ID and the private ssh key for the dispatcher.
