Compute Node Substrate Configuration and Startup

Now that your compute node is fully configured, you are ready to configure Fuzzball Substrate to act as a Compute node agent and enable/start it.

You begin by adding the following variables to /etc/default/fuzzball-substrate.env. This lets Substrate know where it should look to find its configuration files. /fuzzball/shared in our example is the mount point of the file system shared by Orchestrate and the Substrate nodes.

# cat >/etc/default/fuzzball-substrate.env<<EOF
FB_POLL_CONFIG=/fuzzball/shared/substrate/substrate-config.yaml

# aids crash recovery
FB_MOUNTNS=true
EOF

Now you can enable/start the service like so.

# systemctl enable --now fuzzball-substrate.service

At this point you have installed Fuzzball Orchestrate on a server node and Fuzzball Substrate on a compute node! Next, follow the initial configuration guide to get add your compute node to the cluster, configure Fuzzball Orchestrate to use storage, and start adding users!
